RISK FACTORS

Investing in our securities involves a high degree of risk. Before investing in our securities, you should carefully consider the risks, uncertainties and assumptions described below and discussed under the heading “Risk Factors” included in our most recent Annual Report on Form 10-K for the year ended December 31, 2016, which is incorporated by reference into this prospectus, and which may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future. Our business, financial condition, results of operations and future growth prospects could be materially and adversely affected by any of these risks. In these circumstances, the market price of our common stock could decline, and you may lose all or part of your investment. Please see “Cautionary Note Regarding Forward-Looking Statements” and “Incorporation by Reference.”

Risks Related to This Offering

The sale or issuance of our common stock to Lincoln Park may cause dilution and the sale of the shares of common stock acquired by Lincoln Park, or the perception that such sales may occur, could cause the price of our common stock to fall.

On August 8, 2017, we entered into the Purchase Agreement with Lincoln Park, pursuant to which Lincoln Park has committed to purchase up to $15,000,000 of our common stock. Upon the execution of the Purchase Agreement, we issued 450,000 Commitment Shares to Lincoln Park as a fee for its commitment to purchase shares of our common stock under the Purchase Agreement. The remaining shares of our common stock that may be issued under the Purchase Agreement may be sold by us to Lincoln Park at our discretion from time to time over a 30-month period commencing after the satisfaction of certain conditions set forth in the Purchase Agreement, including that the SEC has declared effective the registration statement that includes this prospectus. The purchase price for the shares that we may sell to Lincoln Park under the Purchase Agreement will fluctuate based on the price of our common stock. Depending on market liquidity at the time, sales of such shares may cause the trading price of our common stock to fall.

We generally have the right to control the timing and amount of any future sales of our shares to Lincoln Park. Additional sales of our common stock, if any, to Lincoln Park will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to Lincoln Park all, some, or none of the additional shares of our common stock that may be available for us to sell pursuant to the Purchase Agreement. If and when we do sell shares to Lincoln Park, after Lincoln Park has acquired the shares, Lincoln Park may resell all, some or none of those shares at any time or from time to time in its discretion. Therefore, sales to Lincoln Park by us could result in substantial dilution to the interests of other holders of our common stock. Additionally, the sale of a substantial number of shares of our common stock to Lincoln Park, or the anticipation of such sales, could make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect sales.

We may require additional financing to sustain our operations and without it we may not be able to continue operations.

At June 30, 2017, we had cash of $7,702,000 and a working capital surplus of $5,635,000. We had an operating cash flow deficit of $5,116,000 for the six months ended June 30, 2017 and for the year ended December 31, 2016, an operating cash flow deficit of $7,760,000. The Company believes that its existing cash, and the potential proceeds available under the Purchase Agreement with Lincoln Park, should be sufficient to fund the Company’s operations for at least the next twelve months. We have generated significant losses to date and expect to continue to incur significant operating losses as we advance our product candidates through drug development and the regulatory process. In the future, we will be dependent on obtaining funding from third parties, such as proceeds from the issuance of debt, sale of equity, funded research and development programs and payments under partnership and collaborative agreements, in order to maintain our operations and meet our obligations to licensors. There is no guarantee that debt, additional equity or other funding will be available to us on acceptable terms, or at all.

We may direct Lincoln Park to purchase up to $15,000,000 worth of shares of our common stock under the Purchase Agreement over a 30-month period generally in amounts up to 150,000 shares of our common stock, which may be increased to up to 500,000 shares of our common stock depending on the market price of our common stock at the time of sale and subject to a maximum limit of $1,000,000 per purchase, on any such business day. Assuming a purchase price of $0.595 per share (the closing sale price of the common stock on August 17, 2017) and the purchase by Lincoln Park of the 6,850,000 purchase shares, proceeds to us would be $4,075,750.

Table of Contents

The extent we rely on Lincoln Park as a source of funding will depend on a number of factors including, the prevailing market price of our common stock and the extent to which we are able to secure working capital from other sources. If obtaining sufficient funding from Lincoln Park were to prove unavailable or prohibitively dilutive, we will need to secure another source of funding in order to satisfy our working capital needs. Even if we sell all $15,000,000 under the Purchase Agreement to Lincoln Park, we may still need additional capital to fully implement our business, operating and development plans. Should the financing we require to sustain our working capital needs be unavailable or prohibitively expensive when we require it, the consequences could be a material adverse effect on our business, operating results, financial condition and prospects.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as “intends,” “believes,” “anticipates,” “indicates,” “plans,” “expects,” “suggests,” “may,” “should,” “potential,” “designed to,” “will” and similar references. Such statements include, but are not limited to, statements about: our ability to successfully develop RXI-109, Samcyprone™, and our other product candidates (collectively, “our product candidates”); the future success of our clinical trials with our product candidates; the timing for the commencement and completion of clinical trials; the future success of our strategic partnerships; and our ability to implement cost-saving measures. Forward-looking statements are neither historical facts nor assurances of future performance. These statements are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions.

Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results and financial condition may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others: the risk that our clinical trials with our product candidates may not be successful in evaluating the safety and tolerability of these candidates or providing evidence of increased surgical scar reduction compared to placebo or clearance of common warts; the successful and timely completion of clinical trials; uncertainties regarding the regulatory process; the availability of funds and resources to pursue our research and development projects, including clinical trials with our product candidates; general economic conditions and those identified in this prospectus under the heading “Risk Factors” and in other filings the Company periodically makes with the Securities and Exchange Commission. Forward-looking statements contained in this prospectus speak as of the date hereof and the Company does not undertake to update any of these forward-looking statements to reflect a change in its views or events or circumstances that occur after such date.

In evaluating our business, prospective investors should carefully consider these factors in addition to the other information set forth in this prospectus, including under the caption “Risk Factors.” All forward-looking statements included in this document are based on information available to us on the date hereof. We disclaim any intent to update any forward-looking statements.

USE OF PROCEEDS

This prospectus relates to shares of our common stock that may be offered and sold from time to time by Lincoln Park. We will receive no proceeds from the sale of shares of common stock by Lincoln Park in this offering. We may receive up to $15,000,000 in aggregate gross proceeds under the Purchase Agreement from any sales we make to Lincoln Park pursuant to the Purchase Agreement after the date of this prospectus. We estimate that the net proceeds to us from the sale of our common stock to Lincoln Park pursuant to the Purchase Agreement will be up to $14,900,000 over an approximately 30-month period, assuming that we sell the full amount of our common stock that we have the right, but not the obligation, to sell to Lincoln Park under the Purchase Agreement, and after other estimated fees and expenses. See “Plan of Distribution” elsewhere in this prospectus for more information.

We expect to use any proceeds that we receive under the Purchase Agreement for working capital and general corporate purposes.

LINCOLN PARK TRANSACTION

General

On August 8, 2017, we entered into the Purchase Agreement and the Registration Rights Agreement with Lincoln Park. Pursuant to the terms of the Purchase Agreement, Lincoln Park has agreed to purchase from us up to $15,000,000 of our common stock (subject to certain limitations) from time to time during the term of the Purchase Agreement. Pursuant to the terms of the Registration Rights Agreement, we have filed with the SEC the registration statement that includes this prospectus to register for resale under the Securities Act the shares that have been or may be issued to Lincoln Park under the Purchase Agreement.

Pursuant to the terms of the Purchase Agreement, at the time we signed the Purchase Agreement and the Registration Rights Agreement, we issued 450,000 Commitment Shares to Lincoln Park as consideration for its commitment to purchase shares of our common stock under the Purchase Agreement.

We do not have the right to commence any sales to Lincoln Park under the Purchase Agreement until certain conditions set forth in the Purchase Agreement, all of which are outside of Lincoln Park’s control, have been satisfied, including the registration statement that includes this prospectus being declared effective by the SEC. Thereafter, we may, from time to time and at our sole discretion, direct Lincoln Park to purchase shares of our common stock in amounts up to 150,000 shares on any single business day, which amounts may be increased to up to 500,000 shares of our common stock depending on the market price of our common stock at the time of sale but in no event greater than $1,000,000 per such purchase. The purchase price per share is based on the market price of our common stock immediately preceding the time of sale as computed under the Purchase Agreement. Lincoln Park may not assign or transfer its rights and obligations under the Purchase Agreement.

Under applicable rules of The NASDAQ Capital Market, in no event may we issue or sell to Lincoln Park under the Purchase Agreement shares of our common stock in excess of the Exchange Cap (which is 4,647,142 shares, or 19.99% of the shares of our common stock outstanding immediately prior to the execution of the Purchase Agreement), unless (i) we obtain stockholder approval to issue shares of common stock in excess of the Exchange Cap or (ii) the average price of all applicable sales of our common stock to Lincoln Park under the Purchase Agreement equals or exceeds $0.6422 per share (which represents the closing consolidated bid price of our common stock on August 8, 2017, plus an incremental amount to account for our issuance of the Commitment Shares to Lincoln Park), such that the transactions contemplated by the Purchase Agreement are exempt from the Exchange Cap limitation under applicable NASDAQ rules. In any event, the Purchase Agreement specifically provides that we may not issue or sell any shares of our common stock under the Purchase Agreement if such issuance or sale would breach any applicable rules or regulations of The NASDAQ Capital Market.

The Purchase Agreement also prohibits us from directing Lincoln Park to purchase any shares of common stock if those shares, when aggregated with all other shares of our common stock then beneficially owned by Lincoln Park and its affiliates, would result in Lincoln Park and its affiliates exceeding the Beneficial Ownership Cap.

Purchase of Shares Under the Purchase Agreement

Under the Purchase Agreement, on any business day selected by us, we may direct Lincoln Park to purchase up to 150,000 shares of our common stock on any such business day, which we refer to as a “Regular Purchase,” provided, however, that (i) the Regular Purchase may be increased to up to 200,000 shares, provided that the closing sale price is not below $0.65 on the purchase date, (ii) the Regular Purchase may be increased to up to 250,000 shares, provided that the closing sale price is not below $0.75 on the purchase date, (iii) the Regular Purchase may be increased to up to 300,000 shares, provided that the closing sale price is not below $0.80 on the purchase date, (iv) the Regular Purchase may be increased to up to 350,000 shares, provided that the closing sale price is not below $0.90 on the purchase date, and (v) the Regular Purchase may be increased to up to 500,000 shares, provided that the closing sale price is not below $1.00 on the purchase date. In each case, the maximum amount of any single Regular Purchase may not exceed $1,000,000 per purchase. The purchase price per share for each such Regular Purchase will be equal to the lower of:

 

•

the lowest sale price for our common stock on the purchase date of such shares; or

 

•

the arithmetic average of the three lowest closing sale prices for our common stock during the 10 consecutive business days ending on the business day immediately preceding the purchase date of such shares.

Table of Contents

In addition to Regular Purchases described above, we may also direct Lincoln Park, on any business day on which we have properly submitted a Regular Purchase notice and the closing sale price of our common stock is not below $0.60 (subject to adjustment for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction as provided in the Purchase Agreement), to purchase an additional amount of our common stock, which we refer to as an “Accelerated Purchase,” not to exceed the lesser of:

 

•

30% of the aggregate shares of our common stock traded during normal trading hours on the purchase date; and

 

•

3 times the number of purchase shares purchased pursuant to the corresponding Regular Purchase.

The purchase price per share for each such Accelerated Purchase will be equal to the lower of:

 

•

97% of the volume weighted average price during (i) the entire trading day on the purchase date, if the volume of shares of our common stock traded on the purchase date has not exceeded a volume maximum calculated in accordance with the Purchase Agreement, or (ii) the portion of the trading day of the purchase date (calculated starting at the beginning of normal trading hours) until such time at which the volume of shares of our common stock traded has exceeded such volume maximum; or

 

•

the closing sale price of our common stock on the accelerated purchase date.

In addition to the Regular Purchases and Accelerated Purchases described above, from time to time after the 10^th day following the date that we are first able to begin selling shares to Lincoln Park under the Purchase Agreement, we may also direct Lincoln Park, on any business day that the closing price of our common stock is not below $0.75 (subject to adjustment for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction), to purchase additional amounts of our common stock, which we refer to as an “Additional Purchase,” provided, however, that (i) we may direct Lincoln Park to purchase shares in an Additional Purchase only if at least 20 business days have passed since the most recent Additional Purchase, as applicable, was completed, (ii) Lincoln Park’s committed obligation under any single Additional Purchase shall not exceed $500,000, and (iii) Lincoln Park’s committed obligation under all Additional Purchases shall not exceed $3,000,000 in the aggregate.

The purchase price for each such Additional Purchase shall be equal to the lower of:

 

•

95% of the purchase price under a Regular Purchase on the date we give notice for the related Additional Purchase; or

 

•

$2.00 per share.

In the case of the Regular Purchases, Accelerated Purchases and Additional Purchases, the purchase price per share will be equitably adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction occurring during the business days used to compute the purchase price.

Other than as described above, there are no trading volume requirements or restrictions under the Purchase Agreement, and we will control the timing and amount of any sales of our common stock to Lincoln Park.

Events of Default

Events of default under the Purchase Agreement include the following:

 

•

the effectiveness of the registration statement of which this prospectus forms a part lapses for any reason (including, without limitation, the issuance of a stop order), or any required prospectus supplement and accompanying prospectus are unavailable for the resale by Lincoln Park of our common stock offered hereby, and such lapse or unavailability continues for a period of 10 consecutive business days or for more than an aggregate of 30 business days in any 365-day period;

 

•

suspension by our principal market of our common stock from trading for a period of one business day;

 

15

---

Table of Contents

•

the de-listing of our common stock from The NASDAQ Capital Market, our principal market, provided our common stock is not immediately thereafter trading on the New York Stock Exchange, the NASDAQ Global Market, the NASDAQ Global Select Market, the NYSE Market, the OTC Bulletin Board or OTC Markets (or nationally recognized successor thereto);

 

•

the failure of our transfer agent to issue to Lincoln Park shares of our common stock within three business days after the applicable date on which Lincoln Park is entitled to receive such shares;

 

•

any breach of the representations or warranties or covenants contained in the Purchase Agreement or Registration Rights Agreement that has or could have a material adverse effect on us and, in the case of a breach of a covenant that is reasonably curable, that is not cured within five business days;

 

•

if at any time the Exchange Cap is reached, to the extent applicable;

 

•

any voluntary or involuntary participation or threatened participation in insolvency or bankruptcy proceedings by or against us; or

 

•

if at any time we are not eligible to transfer our common stock electronically.

Lincoln Park does not have the right to terminate the Purchase Agreement upon any of the events of default set forth above. During an event of default, all of which are outside of Lincoln Park’s control, we may not direct Lincoln Park to purchase any shares of our common stock under the Purchase Agreement.

Our Termination Rights

We have the unconditional right, at any time, for any reason and without any payment or liability to us, to give notice to Lincoln Park to terminate the Purchase Agreement. In the event of bankruptcy proceedings by or against us, the Purchase Agreement will automatically terminate without action of any party.

No Short-Selling or Hedging by Lincoln Park

Lincoln Park has agreed that neither it nor any of its affiliates shall engage in any direct or indirect short-selling or hedging of our common stock during any time prior to the termination of the Purchase Agreement.

Prohibitions on Variable Rate Transactions

There are no restrictions on future financings, rights of first refusal, participation rights, penalties or liquidated damages in the Purchase Agreement or Registration Rights Agreement other than a prohibition on entering into a “Variable Rate Transaction,” as defined in the Purchase Agreement.

Effect of Performance of the Purchase Agreement on Our Stockholders

All 7,300,000 shares registered in this offering which have been or may be issued or sold by us to Lincoln Park under the Purchase Agreement are expected to be freely tradable. It is anticipated that shares registered in this offering will be sold over a period of up to 30 months commencing on the date that the registration statement including this prospectus becomes effective. The sale by Lincoln Park of a significant amount of shares registered in this offering at any given time could cause the market price of our common stock to decline and to be highly volatile. Sales of our common stock to Lincoln Park, if any, will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to Lincoln Park all, some or none of the additional shares of our common stock that may be available for us to sell pursuant to the Purchase Agreement. If and when we do sell shares to Lincoln Park, after Lincoln Park has acquired the shares, Lincoln Park may resell all, some or none of those shares at any time or from time to time in its discretion. Therefore, sales to Lincoln Park by us under the Purchase Agreement may result in substantial dilution to the interests of other holders of our common stock. In addition, if we sell a substantial number of shares to Lincoln Park under the Purchase Agreement, or if investors expect that we will do so, the actual sales of shares or the mere existence of our arrangement with Lincoln Park may make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect such sales. However, we have the right to control the timing and amount of any additional sales of our shares to Lincoln Park and the Purchase Agreement may be terminated by us at any time at our discretion without any cost to us.

Table of Contents

Pursuant to the terms of the Purchase Agreement, we have the right, but not the obligation, to direct Lincoln Park to purchase up to $15,000,000 of our common stock, exclusive of the 450,000 shares issued to Lincoln Park on such date as a commitment fee. Depending on the price per share at which we sell our common stock to Lincoln Park pursuant to the Purchase Agreement, we may need to sell to Lincoln Park under the Purchase Agreement more shares of our common stock than are offered under this prospectus in order to receive aggregate gross proceeds equal to the $15,000,000 total commitment available to us under the Purchase Agreement. If we choose to do so, we must first register for resale under the Securities Act such additional shares of our common stock, which could cause additional substantial dilution to our stockholders. The number of shares ultimately offered for resale by Lincoln Park under this prospectus is dependent upon the number of shares we direct Lincoln Park to purchase under the Purchase Agreement.

The Purchase Agreement prohibits us from issuing or selling to Lincoln Park under the Purchase Agreement (i) shares of our common stock in excess of the Exchange Cap, unless we obtain stockholder approval to issue shares in excess of the Exchange Cap or the average price of all applicable sales of our common stock to Lincoln Park under the Purchase Agreement equal or exceed $0.6422 per share, such that the transactions contemplated by the Purchase Agreement are exempt from the Exchange Cap limitation under applicable NASDAQ rules, and (ii) any shares of our common stock if those shares, when aggregated with all other shares of our common stock then beneficially owned by Lincoln Park and its affiliates, would exceed the Beneficial Ownership Cap.

The following table sets forth the amount of gross proceeds we would receive from Lincoln Park from our sale of shares to Lincoln Park under the Purchase Agreement at varying purchase prices:

 

Assumed Average Purchase Price Per Share		Number of Registered Shares to be Issued if Full Purchase (1)				Percentage of Outstanding Shares After Giving Effect to the Issuance to Lincoln Park (2)				Proceeds from the Sale of Shares to Lincoln Park Under the $15M Purchase Agreement

Although the Purchase Agreement provides that we may sell up to $15,000,000 of our common stock to Lincoln Park, we are only registering 7,300,000 shares under this prospectus which represents: (i) 450,000 shares that we already issued to Lincoln Park as a commitment fee for making the commitment under the Purchase Agreement, and (ii) an additional 6,850,000 shares which may be issued to Lincoln Park in the future under the Purchase Agreement, if and when we sell shares to Lincoln Park under the Purchase Agreement, and which may or may not cover all the shares we ultimately sell to Lincoln Park under the Purchase Agreement, depending on the purchase price per share. As a result, we have included in this column only those shares that we are registering in this offering. If we seek to issue shares of our common stock, including shares from other transactions that may be aggregated with the transactions contemplated by the Purchase Agreement under the applicable rules of The NASDAQ Capital Market, in excess of 4,647,142 shares, or 19.99% of the total common stock outstanding immediately prior to the execution of the Purchase Agreement, we may be required to seek stockholder approval in order to be in compliance with the rules of The NASDAQ Capital Market.

The denominator is based on 23,247,338 shares outstanding as of August 7, 2017, adjusted to include the issuance of (i) 450,000 commitment shares issued to Lincoln Park upon the execution of the Purchase Agreement, and (ii) the number of shares set forth in the adjacent column which we would have sold to Lincoln Park, assuming the purchase price in the adjacent column. The numerator is based on the number of shares issuable under the Purchase Agreement at the corresponding assumed purchase price set forth in the adjacent column.

DESCRIPTION OF SECURITIES

Authorized Capital Stock

Our authorized capital stock consists of 100,000,000 shares of common stock, par value $0.0001 per share, and 10,000,000 shares of preferred stock, par value $0.0001 per share, of which 8,100 are authorized as Series B Convertible Preferred Stock and 1,800,000 are authorized as Series C Convertible Preferred Stock.

As of August 8, 2017, there were 23,697,338 shares of our common stock issued and outstanding. There were no shares of our Series B Convertible Preferred Stock or Series C Convertible Preferred Stock issued or outstanding.

Common Stock

The holders of our common stock are entitled to one vote for each share on all matters voted on by stockholders, including elections of directors, and, except as otherwise required by law or provided in any resolution adopted by our Board with respect to any series of preferred stock, the holders of such shares will possess all voting power. Our certificate of incorporation does not provide for cumulative voting in the election of directors. The shares of common stock have no conversion rights or sinking fund provisions and are not liable for further call or assessment. Subject to any preferential rights of any outstanding series of our preferred stock created by our Board from time to time, the holders of common stock are entitled to such dividends as may be declared from time to time by our Board from funds available therefor and upon liquidation are entitled to receive their pro rata share of all assets available for distribution to such holders. Our common stock is not redeemable.

The holders of our common stock have no preemptive rights.

The rights, preferences and privileges of holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

Preferred Stock

Our Board of Directors, without further action by the holders of our common stock, may issue shares of our preferred stock in one or more series. Our Board is vested with the authority to fix by resolution the designations, preferences and relative, participating, optional or other special rights, and such qualifications, limitations or restrictions thereof, including, without limitation, redemption rights, dividend rights, liquidation preferences and conversion or exchange rights of any class or series of preferred stock, and to fix the number of classes or series of preferred stock, the number of shares constituting any such class or series and the voting powers for each class or series.

The authority possessed by our Board to issue preferred stock could potentially be used to discourage attempts by third parties to obtain control of us through a merger, tender offer, proxy contest or otherwise by making such attempts more difficult or more costly. Our Board may issue preferred stock with voting rights or conversion rights that, if exercised, could adversely affect the voting power of the holders of common stock. There are no current agreements or understandings with respect to the future issuance of preferred stock and our Board has no present intention to issue any additional shares of preferred stock.

Outstanding Warrants

As of August 8, 2017, we had outstanding warrants to purchase 14,077,779 shares of common stock at a weighted-average exercise price of $1.30 per share, of which 1,300,002 expire on June 2, 2020 and 12,777,777 expire on December 21, 2021.

Anti-Takeover Effects of Provisions of the Certificate of Incorporation and Bylaws

Certificate of Incorporation and Bylaw Provisions. Our certificate of incorporation and bylaws include a number of provisions that may have the effect of encouraging persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with our board of directors rather than pursue non-negotiated takeover attempts. They are intended to enhance long-term value to our stockholders by increasing the likelihood of continued stability in the composition of our board of directors and its policies and discouraging certain types of transactions that may involve an actual or threatened acquisition of us. These provisions are also designed to reduce our vulnerability to an unsolicited acquisition proposal and to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our stock that could result from actual or rumored takeover attempts. These provisions include the items described below.

Filling Vacancies. Any vacancy on our board of directors, however occurring, including a vacancy resulting from an increase in the size of our board of directors, may only be filled by the affirmative vote of a majority of our directors then in office even if less than a quorum.

Table of Contents

No Written Consent of Stockholders. Our certificate of incorporation provides that all stockholder actions are required to be taken by a vote of the stockholders at an annual or special meeting, and that stockholders may not take any action by written consent in lieu of a meeting.

Meetings of Stockholders. Our certificate of incorporation provides that only our board of directors or holders of 5% or more of our outstanding shares of common stock may call special meetings of stockholders and only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders. Our bylaws limit the business that may be conducted at an annual meeting of stockholders to those matters properly brought before the meeting.

Advance Notice Requirements. Our bylaws include advance notice procedures with regard to stockholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of our stockholders. These procedures provide that notice of stockholder proposals must be timely given in writing to our corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the annual meeting for the preceding year. The notice must contain certain information specified in the amended and restated bylaws.

Amendment to Bylaws and Certificate of Incorporation. As required by the Delaware General Corporation Law (the “DGCL”) any amendment of our certificate of incorporation must first be approved by a majority of our board of directors and, if required by law or our certificate of incorporation, thereafter be approved by a majority of the outstanding shares entitled to vote on the amendment, and a majority of the outstanding shares of each class entitled to vote thereon as a class. Our bylaws may be amended by the affirmative vote of a majority vote of the directors then in office, subject to any limitations set forth in the bylaws.

Blank Check Preferred Stock. Our amended and restated certificate of incorporation provides for 10,000,000 authorized shares of preferred stock. The existence of authorized but unissued shares of preferred stock may enable our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest, or otherwise. For example, if in the due exercise of its fiduciary obligations, our board of directors were to determine that a takeover proposal is not in the best interests of our company or our stockholders, our board of directors could cause shares of preferred stock to be issued without stockholder approval in one or more private offerings or other transactions that might dilute the voting or other rights of the proposed acquirer or insurgent stockholder or stockholder group. In this regard, our amended and restated certificate of incorporation grants our board of directors broad power to establish the rights and preferences of authorized and unissued shares of preferred stock. The issuance of shares of preferred stock could decrease the amount of earnings and assets available for distribution to holders of shares of common stock. The issuance may also adversely affect the rights and powers, including voting rights, of these holders and may have the effect of delaying, deterring, or preventing a change of control of us.

Delaware Business Combination Statute

Section 203 of the DGCL provides that, subject to exceptions set forth therein, an “interested stockholder” of a Delaware corporation shall not engage in any business combination, including mergers or consolidations or acquisitions of additional shares of the corporation, with the corporation for a three-year period following the date that such stockholder becomes an interested stockholder unless:

 

•

Prior to such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

 

•

Upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, other than statutorily excluded shares; or

 

•

On or subsequent to such date, the business combination is approved by the board of directors of the corporation and authorized at an annual or special meeting of the stockholders by the affirmative vote of at least 66-2/3% of the outstanding voting stock which is not owned by the interested stockholder.

Except as otherwise set forth in Section 203, an “interested stockholder” is defined to include:

 

•

Any person that is the owner of 15% or more of the outstanding voting stock of the corporation, or is an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within three years immediately prior to the date of determination; and

 

•

The affiliates and associates of any such person.

Table of Contents

Section 203 may make it more difficult for a person who would be an interested stockholder to effect various business combinations with a corporation for a three-year period. We have not elected to be exempt from the restrictions imposed under Section 203. The provisions of Section 203 may encourage persons interested in acquiring us to negotiate in advance with our board, since the stockholder approval requirement would be avoided if a majority of the directors then in office approves either the business combination or the transaction which results in any such person becoming an interested stockholder. Such provisions also may have the effect of preventing changes in our management. It is possible that such provisions could make it more difficult to accomplish transactions, which our stockholders may otherwise deem to be in their best interests.

Exchange Listing

Our common stock is listed on the Nasdaq Capital Market under the trading symbol “RXII.” The warrants issued in connection with the Company’s underwritten public offering on December 21, 2016 are listed on the Nasdaq Capital Market under the trading symbol “RXIIW.”

DESCRIPTION OF BUSINESS

Overview

RXi is a clinical-stage company developing innovative therapeutics based on our proprietary self-delivering RNAi (sd-rxRNA^®) platform and Samcyprone™ which address significant unmet medical needs. We have a pipeline of discovery, preclinical and clinical product candidates in the areas of dermatology, ophthalmology and cell-based cancer immunotherapy. The Company’s clinical development programs include RXI-109, an sd-rxRNA for the treatment of dermal and ocular scarring, and Samcyprone™, a topical immunomodulator, for the treatment of warts. The Company’s pipeline, coupled with our extensive patent portfolio, provides for product development and business development opportunities across a broad spectrum of therapeutic areas.

Our Pipeline

Our pipeline focuses on three areas: dermatology, including cosmetic product development, ophthalmology and cell-based cancer immunotherapy. Our RNAi therapies are designed to “silence,” or down-regulate, the expression of a specific gene that may be over-expressed in a disease condition and our topical immunotherapy agent, Samcyprone™, treats diseases by inducing, enhancing or suppressing an immune response in the skin. The following is a summary of our current product candidates and their development status:

 

Dermatology Franchise

RXI-109—Dermal Scarring

The Company’s lead product candidate and first RNAi clinical product candidate, RXI-109, is a self-delivering RNAi compound (sd-rxRNA) that commenced human clinical trials in 2012. RXI-109 is designed to reduce the expression of connective tissue growth factor (“CTGF”), a critical regulator of several biological pathways involved in fibrosis, including scar formation in the skin and eye. RXI-109 is currently being evaluated in a Phase 2 clinical trial, Study 1402, to prevent or reduce dermal scarring following scar revision surgery of an existing hypertrophic scar.

 

25

Table of Contents

The Company initially conducted two Phase 1 clinical trials evaluating RXI-109 in a surgical setting. Both trials demonstrated the safety and tolerability of RXI-109 in ascending single and multi-doses, and also provided the first evidence of clinical activity in a surgical setting. With the successful completion of the Phase 1 trials, in November 2013 the Company initiated its Phase 2 program for RXI-109 with Study 1301, a Phase 2 clinical trial evaluating the use of RXI-109 to prevent the recurrence of hypertrophic scars following scar revision surgery. Enrollment and dosing for this study have been completed.

Preliminary data observations from Study 1301 were used in the design of the Company’s second Phase 2 clinical trial in hypertrophic scars, Study 1402, which commenced in July 2014. In October 2015, we reported that preliminary data from Study 1402 demonstrated that scars at revision sites were judged to be better at three months after a treatment regimen with five mg/cm intradermal administration of RXI-109 than scars at untreated revision sites in those same subjects. Based in part on this new information, two more cohorts (Cohorts 3 and 4) were added to Study 1402 in November 2015. For these two cohorts, the number of doses was increased to either eight or nine doses of RXI-109 over a six-month period to better cover the extended wound healing/scarring profile of hypertrophic scars. Enrollment of subjects into these two new cohorts completed ahead of schedule during the third quarter of 2016.

In December 2016, the Company announced that preliminary data from the first two cohorts from Study 1402 at nine months confirmed the positive differentiation by a blinded panel of observers from untreated surgery incisions in hypertrophic scars from the previously presented data for a subset of subjects treated with five mg/cm of RXI-109 at three months. In addition, these data extend this observation to all time points, including the post-treatment follow-up period through nine months post-surgery. RXI-109 was safe and well tolerated. Additionally, as expected, the limited three-month data available from Cohort 3 appeared to align with that of the first two cohorts as these subjects all had the same dosing schedule through the third month. A complete read-out of the whole study, including all four cohorts with follow-up until nine months post-surgery, is expected in the second half of 2017.

Scarring represents a high unmet medical need as there are currently no U.S. Food and Drug Administration (“FDA”) approved therapies in the U.S. for the treatment and prevention of scars in the skin. Scar revision surgery is one treatment option, but often the scar recurs. If approved, RXI-109 could be a “first-in-class” RNAi treatment for the prevention or reduction of post-surgical dermal scarring. Given the large number of surgical procedures, there is a significant market for a scar prevention therapeutic such as RXI-109.

Samcyprone™—Warts

In December 2014, the Company broadened its clinical pipeline with an exclusive, global license to Samcyprone™, our second clinical candidate. Samcyprone™ is a proprietary topical formulation of the small molecule diphenylcyclopropenone (“DPCP”), an immunomodulator that works by initiating a T-cell response. The use of Samcyprone™ allows sensitization using much lower concentrations of DPCP than are used with existing compounded DPCP solutions, avoiding hyper-sensitization to subsequent challenge doses. DPCP, the active ingredient in Samcyprone™, has long been used to treat warts and has also been used for several other indications, such as to stimulate hair re-growth in alopecia areata and to clear cutaneous metastases of melanoma. In March 2015, the FDA granted Orphan Drug Designation to the Company for Samcyprone™ for the treatment of malignant melanoma stages IIb to IV. Samcyprone™ is currently being evaluated in a Phase 2a clinical trial, Study 1502, for the clearance of common warts.

Study 1502, initiated in December 2015, includes a sensitization phase in which a spot on the subject’s upper arm and one or more warts are treated with Samcyprone™. After being sensitized in this way, the subjects enter into the treatment phase where up to four warts are treated on a once weekly basis for ten weeks with a ten-fold lower concentration of Samcyprone™ than in the sensitization phase. During the trial, the warts are scored, photographed and measured to monitor the level of clearance.

In December 2016, the Company announced the results from a preliminary review of sensitization and wart clearance data from a subset of subjects that had completed the ten-week treatment phase of Study 1502. Results showed that greater than 90% of the subjects demonstrated a sensitization response, a prerequisite to be able to develop a therapeutic response. Additionally, more than 60% of the subjects responded to the treatment by exhibiting either complete or greater than 50% clearance of all treated warts with up to ten weekly treatments. Samcyprone™ treatment has been generally safe and well tolerated and has had drug-related adverse events relating to local reactions, which are typically expected for this type of treatment due to the sensitization and challenge responses in the skin. The Company added a second cohort, which is expected to be fully enrolled in the second half of 2017, to explore the opportunity to reduce the sensitization dose level, which will be more convenient to physicians and subjects. Early read-outs of the study are anticipated in the second half of 2017.

Table of Contents

Cutaneous warts are extremely common, being experienced by most people at some time during their lives. Although most warts will spontaneously disappear without treatment, treatment is sought for recalcitrant warts and to prevent recurrence. There are many different treatment modalities for warts, including physical destruction and immunomodulation. However, treatment of warts is complicated by low success rates, prolonged duration of therapy and the potential for recurrence. There is a clear unmet need for new therapies for warts, and if approved, Samcyprone™ could be a more effective and convenient treatment than the currently available therapies.

Additional Dermatology Programs

In addition to our dermal scarring and wart programs, we continue to advance our preclinical and discovery programs with our sd-rxRNA technology. The Company has selected tyrosinase (“TYR”) and collagenase (“MMP1”) as targets for our self-delivering platform because they are relevant for both consumer health and therapeutic development. TYR is a key enzyme in the synthesis of melanin. Melanin is produced by melanocytes and is the pigment that gives human skin, hair and eyes their color. The inhibition of TYR can play a key role in the management of skin conditions including cutaneous hyperpigmentation disorders such as lentigines (freckles, age spots and liver spots) and possibly melanoma. MMP1 is a key enzyme involved in the breakdown of extracellular matrix. Reduction of MMP1 may be beneficial in the treatment of skin aging disorders, arthritis, acne scarring, blistering skin disorders, corneal erosions, endometriosis and possibly cancer metastasis.

Cosmetic Development

Cosmetics are compounds that affect the appearance of the skin and make no preventative or therapeutic claims. These compounds may be developed more rapidly than therapeutics, therefore the path to market may be much shorter and less expensive. In October 2015, we announced the selection of lead compounds targeting TYR and MMP1 for cosmetic development.

RXI-231 — Uneven Skin Tone and Pigmentation

RXI-231, an sd-rxRNA compound targeting TYR, is in development as a cosmetic ingredient that may improve the appearance of uneven skin tone and pigmentation. Efficacy and toxicity testing in cell culture and skin equivalents for RXI-231 was successfully completed in December 2016. The Company initiated human testing of RXI-231 in June 2017 with a U.S. clinical testing site. In addition to evaluating safety, the Company will assess the effect of RXI-231 on the appearance of skin pigmentation in a follow-on study.

RXI-185 — Wrinkles and Skin Laxity

RXI-185, an sd-rxRNA compound targeting MMP1, is in development as a cosmetic ingredient that may improve the appearance of wrinkles or skin laxity. Results from studies by the Company have shown a pronounced reduction in MMP1 mRNA levels that correspond to a similar reduction in MMP1 enzyme activity in cell culture in vitro.

RXI-109 – Retinal Scarring

As in dermal scarring, RXI-109 can also be used to target CTGF in the eye, where CTGF is known to be involved in retinal scarring. Building on the work in our dermal clinical program, the Company filed a new investigational drug application (“IND”) in July 2015 for RXI-109 as a potential therapeutic for the scarring component of retinal diseases in the eye, such as wet age-related macular degeneration (“AMD”). In November 2015, we initiated a Phase 1/2 clinical trial to evaluate the safety and clinical activity of RXI-109 in reducing the progression of retinal scarring.

Study 1501 is a multi-dose, dose escalation study conducted in subjects with AMD with evidence of subretinal fibrosis. Each subject receives four doses of RXI-109 by intraocular injection at one month intervals for a total dosing period of three months. The safety and tolerability of RXI-109, as well as the potential for clinical activity, is evaluated over the course of the study using numerous assessments to monitor the health of the retina and to assess visual acuity. To date, there have been no safety issues that have precluded continuation of dosing. Study 1501 has been completely enrolled and dosing in the third cohort at the highest planned dose level is ongoing. The Company expects to complete subject participation in the study by the end of 2017 and to share top-line data in early 2018.

Currently, there is no effective way to prevent the formation or progression of retinal scars that may occur as a consequence of a number of debilitating ocular diseases. In advanced neo-vascular or wet-AMD, our first area of study, retinal scarring often results in continued vision loss even if the patient is being treated with an anti-vascular endothelial growth factor (“VEGF”) therapy. RXI-109 has the potential to fill this unmet medical need by reducing this continuing damage to the retina and in doing so help preserve these patients’ vision for a longer period of time.

Additional Ophthalmology Programs

In addition to the clinical trial for the use of RXI-109 as a potential therapeutic for retinal scarring, we are advancing other early-stage ophthalmology programs. Currently, the Company is directing its development efforts toward advancing RXI-109 for the treatment of corneal scarring. To date, our preclinical studies have shown that CTGF protein levels are reduced in a dose-dependent manner in both the retina and cornea following an intravitreal injection of RXI-109 in monkeys. Elevated CTGF is implicated in the formation of corneal scarring that can occur after eye injury or after certain infections, and it has been proposed that a reduction of CTGF may be an important step towards reducing corneal scarring. Scarring of the cornea can impact the transparency of the cornea, and thus negatively impact vision. We are currently working towards a non-invasive delivery formulation of RXI-109 to reduce CTGF in the front of the eye.

Cell-based Cancer Immunotherapy

In January 2017, the Company entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) pursuant to which it acquired 100% of the issued and outstanding shares of capital stock of MirImmune Inc. (“MirImmune”) for an aggregate of 2,750,371 shares of common stock of the Company and 1,118,224 shares of Series C Convertible Preferred Stock (the “Series C Convertible Preferred Stock”). On June 9, 2017, with the approval of the Company’s stockholders in accordance with the stockholder approval requirements of Nasdaq Marketplace Rule 5635, each share of the Company’s Series C Convertible Preferred Stock outstanding was automatically converted into one share of common stock, such that no shares of Series C Convertible Preferred Stock remained issued or outstanding.

Under the terms of the Stock Purchase Agreement, if certain development or commercial milestones are achieved within two years, the Company will be required to either (i) issue to the sellers a number of shares of common stock or (ii) pay the equivalent value in cash.

Prior to its acquisition by the Company, MirImmune was a privately held biopharmaceutical company engaged in the development of cancer immunotherapies. The Company previously granted an exclusive license to MirImmune in March 2015 to utilize the Company’s novel and proprietary sd-rxRNA technology for use in developing ex vivo cell-based cancer immunotherapies.

Our approach to immunotherapy builds on well-established methodologies of adoptive cell transfer. Immune cells, such as T-lymphocytes, are isolated from specific patients or retrieved from allogeneic immune cell banks and then expanded and sometimes processed to express tumor-binding receptors. Our method will introduce a new and important step in ex vivo processing of immune cells. This step uses our sd-rxRNA technology to reduce or eliminate the expression of immunosuppressive receptors or proteins by the therapeutic immune cells, potentially making them less sensitive to tumor resistance mechanism and thus improving their ability to destroy the tumor cells.

The Company’s approach builds on current immunotherapy approaches but provides some key advantages. One major advantage is that pre-treatment with our targeted compounds allows multiple immune checkpoints to be attenuated within the same therapeutic cell, an improvement which could dramatically increase their tumor cell killing capability. In addition, these therapeutic immune cells may lack some known side effects associated with the checkpoint inhibitor toxicity while potentially improving efficacy over current immunotherapy approaches.

Using our sd-rxRNA technology, MirImmune demonstrated in vitro that multiple sd-rxRNA compounds can be used alone or in combination to target and silence extracellular, as well as intracellular, checkpoints in immune cells. Additional in vitro data demonstrated that PD-1 silencing by sd-rxRNA in patient-derived tumor infiltrating lymphocytes (TILs) resulted in enhanced killing of melanoma tumor cells from the same patient in culture. MirImmune also showed in a mouse model of human ovarian cancer that in vivo treatment with mesothelin-targeting CAR T-cells transfected with a PD-1 targeting sd-rxRNA significantly reduced the rate of tumor growth as compared to vehicle control. Furthermore, the silencing of PD-1 in the CAR T-cells isolated from these tumors persisted for at least one month.

In December 2016, new data was provided by MirImmune demonstrating silencing of a number of undisclosed immunosuppressive targets in natural killer cells (NK cells) using our sd-rxRNA compounds. This adds to a remarkable set of immune checkpoint modulation studies in human T-cells, including CAR T-cells and TILs. In immune cells tested to date, the sd-rxRNA treatment results in potent silencing while maintaining close to 100% transfection efficiency and nearly full cell viability. Moreover, the silencing effect has been validated in a number of clinically used cell treatment protocols.

Building on the work completed by MirImmune prior to its acquisition by the Company, our cell-based cancer immunotherapy program with sd-rxRNA includes lead compounds for a number of immune checkpoint targets that provide long lasting immune checkpoint silencing, individually and in combination, in adoptively transferred cells. An improved efficacy upon the silencing of checkpoints has been demonstrated in various types of adoptively transferred cells relevant in cancer immunotherapy, such as CAR T-cells and TILs. The Company’s ongoing discovery programs include, but are not limited to, the evaluation of sd-rxRNA compounds to silence targets related to cytokine release syndrome. The Company has also initiated in vivo evaluations of multiple checkpoint inhibiting sd-rxRNA compounds co-transfected in CAR T-cells in mouse models for solid tumors, with data from this study expected in the second half of 2017.

Additionally, the Company recently selected two sd-rxRNA compounds from its immunotherapy pipeline for preclinical development. For oncology treatments based on adoptive cell transfer (ACT), compounds RXI-762 and RXI-804 suppress the expression of immune checkpoint proteins PD-1 and TIGIT, respectively, which can result in an improved efficacy to the targeted tumors. This decision triggered the selection of a manufacturing facility to initiate production of cGMP grade material, initially for the first of these two compounds (RXI-762). This also supports moving RXI-762 into clinical development as early as 2018 as part of an ACT therapy.

Market Opportunity

As there are currently no FDA-approved drugs to prevent scar formation, a therapeutic of this type could have great benefit for trauma and surgical patients, particularly as a treatment during the surgical revision of existing unsatisfactory scars. According to the American Society for Plastic Surgery, there are approximately 180,000 scar revision surgeries in the United States every year. In addition to cosmetic and reconstructive surgeries, medical interventions which could incorporate an anti-scarring agent include treatment of scarring that results from trauma, surgery or burns (especially relating to raised or hypertrophic scarring or contracture scarring), and surgical revision of existing unsatisfactory scars. Moreover, there are over 42 million medical procedures in the U.S. each year that could potentially benefit from a therapeutic treatment that could successfully reduce or prevent scarring; thus, the market potential is quite large.

AMD is the leading cause of severe vision loss in adults over age 50. According to the National Eye Institute, in 2010 approximately 2.07 million people had AMD. The National Eye Institute further states that as the proportion of people in the U.S. age 65 and older grows larger, more people are developing age-related diseases, such as AMD. Due to the aging population, this number is expected to double to an estimated 5.44 million people in the year 2050. There is no cure for AMD and over 50% of patients start to develop scarring after 2 years on anti-VEGF therapy, the current standard of care. This represents a large number of patients with an unmet medical need that could benefit from a therapeutic treatment that could successfully reduce or prevent scarring in the retina, and thereby improve vision loss.    

Overexpression of CTGF is implicated in dermal scarring, subretinal fibrosis and other fibrotic diseases. Because of this, we believe that RXI-109 or other CTGF-targeting RNAi compounds may be able to treat the fibrotic component of numerous additional indications. These indications are as wide ranging as acute spinal injury, endometriosis, organ fibrosis including liver and pulmonary fibrosis, cutaneous scleroderma and vascular restenosis, in addition to numerous ocular diseases that result in retinal scarring. If the current clinical trials of RXI-109 produce successful results, we may explore opportunities in these additional indications that can be accessed by local administration, starting with intradermal or intravitreal injection. Although the Company does not intend to develop systemic uses of RXI-109 at this time, the Company is open to business development and out-licensing opportunities for those applications.

DPCP, the active ingredient in Samcyprone™, is a small molecule that has been used since the late 1970s to stimulate regrowth of hair in patients with alopecia areata. Recent publications have supported its use as an immunomodulator for the treatment of alopecia areata, warts and cutaneous metastases of malignant melanoma, a combined market potential of over an estimated $1 billion. Although it has been used by physicians for several decades, it has never been reviewed or approved by a regulatory authority as a drug. If FDA approval is granted, Samcyprone™, RXi’s proprietary formulation of DPCP, is expected to achieve market exclusivity.

Despite many advances, there is still a significant unmet need for cancer treatments. There are currently close to 180 therapies across various phases of development in the T-cell immunotherapy market. This growth is supported by robust and opportunistic pipelines targeting various indications. Pharmaceutical and large biotechnology companies are actively looking for complementary technology platforms that enhance their cellular pipelines. Initial clinical trials of adoptive cell transfer, our approach to immunotherapy, have shown limited success in treatment of solid tumors. One of the major issues is the immunosuppressive tumor microenvironment. Multiple inhibitory receptors, or immune checkpoints, are responsible for immunosuppression. Our sd-rxRNA treatment can be seamlessly integrated in existing and new adoptive cell transfer therapies to overcome immunosuppression issues. Our sd-rxRNA compounds silence various immunosuppressive genes and boost the ability of therapeutic cells to kill tumors, while offering a safe and versatile approach to reduction of immunosuppression in therapeutic cells.

Introduction to RNAi

RNAi is a naturally occurring phenomenon where short, double-stranded RNA molecules interfere with the expression of targeted genes. The discovery of RNAi is regarded as a significant advancement in the scientific community, as evidenced by the 2006 Nobel Prize in Medicine awarded to the co-discoverers of RNAi, including Dr. Craig Mello, one of the founders of RXi.

RNAi offers a novel approach to the drug development process because RNAi compounds can potentially be designed to target any one of the thousands of human genes, many of which are “undruggable” by other modalities. The specificity of RNAi is achieved by an intrinsic, well-understood biological mechanism based on designing the sequence of an RNAi compound to match the sequence of the targeted gene. The sequence of the entire human genome is now known, and the mRNA coding sequence for many proteins is already available. Supported by numerous gene-silencing reports and our own research, we believe that this sequence information can be used to design RNAi compounds to interfere with the expression of almost any specific gene.

Our RNAi Therapeutic Platform

The first design of RNAi compounds to be pursued for the development of human therapeutics were short, double-stranded RNAs that included at least one overhanging single-stranded region and limited modifications, known as small-interfering RNA, or siRNA, which we will also refer to as classic siRNA.

We believe that classic siRNAs have drawbacks that may limit the usefulness of those agents as human therapeutics, and that we may be able to utilize the technologies we have licensed and developed internally to optimize RNAi compounds for use as human therapeutic agents. For sd-rxRNA, it is the combination of the duplex length, the nucleotide sequence and the configuration of chemical modifications that are important for effective RNAi therapeutics.

Drug delivery has been the primary challenge in developing RNAi therapeutics since its initial discovery. One conventional solution to the delivery problem involves encapsulation into a lipid-based particle, such as a liposome, to improve circulation time and cellular uptake. Scientists at RXi have used an alternative approach to delivery in which drug-like properties were built into the RNAi compound itself. These novel compounds are termed ‘self-delivering’ RNAi compounds or sd-rxRNA.

sd-rxRNAs are hybrid oligonucleotide compounds that the Company believes combine the beneficial properties of both conventional RNAi and antisense technologies. Traditional, single-stranded antisense compounds have favorable tissue distribution and cellular uptake properties. However, they do not have the intracellular potency that is a hallmark of double-stranded RNAi compounds. Conversely, the duplex structure and hydrophilic character of traditional RNAi compounds results in poor tissue distribution and cellular uptake. In an attempt to combine the best properties of both technologies, sd-rxRNA have a single-stranded phosphorothioate region, a short duplex region, and contain a variety of nuclease-stabilizing and lipophilic chemical modifications. The combination of these features allows sd-rxRNA to achieve efficient spontaneous cellular uptake and potent, long-lasting intracellular activity.

We believe that our next generation sd-rxRNA compounds offer significant advantages over siRNAs used by other companies developing RNAi therapeutics, highlighted by the following characteristics:

 

•

Efficient cellular uptake in the absence of a delivery vehicle;

 

•

Potent RNAi activity;

 

•

More resistant to nuclease degradation than unformulated oligonucleotides;

•

Able to suppress long non-coding RNAs, both in cytoplasm and the nucleus;

 

•

Readily manufactured;

 

•

Potentially more specific for the target gene; and

 

•

More reliable at blocking immune side effects than classic siRNA.

Our Route of Administration

The route by which an RNAi therapeutic is brought into contact with the body depends on the intended organ or tissue to be treated. Delivery routes can be simplified into two major categories: (1) local (when a drug is delivered directly to the tissue of interest); and (2) systemic (when a drug accesses the tissue of interest through the circulatory system). Local delivery may avoid some hurdles associated with systemic approaches such as rapid clearance from circulation and inefficient tissue extravasation (crossing the endothelial barrier from the blood stream). However, the local delivery approach can only be applied to a limited number of organs or tissues (e.g., skin, eye, lung and potentially the central nervous system).

The key to therapeutic success with RNAi lies in delivering intact RNAi compounds to the target tissue and the interior of the target cells. To accomplish this, we have developed a comprehensive platform that includes chemically synthesized RNAi compounds that are optimized for stability and efficacy and combine efficient cellular uptake with a local delivery approach.

Our sd-rxRNA molecules have unique properties that improve tissue and cell uptake. We have studied sd-rxRNA molecules in animal models for dermal and ocular delivery. Direct administration of sd-rxRNA via injection with no additional delivery vehicle to the skin or to the eye demonstrates that target gene silencing can be measured after local administration. The dose levels required for these direct-injection methods are small and suitable for clinical development. The Company has a number of clinical trials currently ongoing with RXI-109, an sd-rxRNA compound, for local delivery in the skin and the eye. Other target tissues that are potentially accessible for local delivery using sd-rxRNA compounds include the lung, the central nervous system, mucosal tissues and sites of inflammation and tumor (direct administration).

We have also studied our sd-rxRNA compounds for use in the well-established methodologies of adoptive cell transfer. Immune cells are isolated from specific patients or retrieved from allogeneic immune cell banks and then expanded and possibly processed to express tumor-binding receptors. Our process involves ex vivo treatment of the immune cells with our sd-rxRNA compounds to inhibit the expression of immune checkpoint genes. The enhanced cells are then returned and used to treat the same patient.

Introduction to Samcyprone™

Immunotherapy is the treatment of disease by inducing, enhancing or suppressing an immune response. Active agents in immunotherapy are collectively called immunomodulators. They are a diverse array of recombinant, synthetic and natural preparations that help to regulate or normalize the immune system.

Our Samcyprone™ Therapeutic Pipeline

Samcyprone™, licensed by the Company in 2014, is a proprietary topical formulation of the small molecule DPCP. DPCP has been used for decades as a treatment to stimulate hair re-growth in patients with alopecia areata and more recently as a treatment for recalcitrant wart removal and as an aid in the reduction of cutaneous metastases of melanoma. As it is currently used, a doctor must prescribe DPCP to be formulated by a compounding facility, generally in acetone. There are no standardized methods of formulation or procedures for use. Because it works by causing an immune response, the level of response can vary greatly from person to person. Moreover, some pharmacies will not even compound it, even if it is prescribed.

Samcyprone™ works by initiating a T-cell response. T-cells or T lymphocytes are a type of white blood cell that play a key role in cell-mediated immunity. The use of Samcyprone™ will improve ease of use, allow for lower sensitizing and challenge doses than in current use and should result in an improved safety margin and a more consistent immune response.

There will be several advantages to using an FDA regulated formulation like the one we are developing. First, the amount of DPCP used in our own ointment formulation is lower than that generally used in acetone formulation. This should result in reduced side effects that happen due to accidental over-sensitization when a higher than necessary concentration is used. Second, we are developing an optimized dosing regimen so that a standardized response can be expected. And third, the ointment formulation will be easier to prescribe and to use than an acetone formulation, allowing for ease of application at the appropriate site on the skin.

Intellectual Property

We protect our proprietary information by means of United States and foreign patents, trademarks and copyrights. In addition, we rely upon trade secret protection and contractual arrangements to protect certain of our proprietary information and products. We have pending patent applications that relate to potential drug targets, compounds we are developing to modulate those targets, methods of making or using those compounds and proprietary elements of our drug discovery platform.

Much of our technology and many of our processes depend upon the knowledge, experience and skills of key scientific and technical personnel. To protect our rights to our proprietary know-how and technology, we require all employees, as well as our consultants and advisors when feasible, to enter into confidentiality agreements that require disclosure and assignment to us of ideas, developments, discoveries and inventions made by these employees, consultants and advisors in the course of their service to us, and we vigorously defend that position with partners, as well as with employees who leave the Company.

We have also obtained rights to various patents and patent applications under licenses with third parties, which require us to pay royalties, milestone payments, or both. The degree of patent protection for biotechnology products and processes, including ours, remains uncertain, both in the United States and in other important markets, because the scope of protection depends on decisions of patent offices, courts and lawmakers in these countries. There is no certainty that our existing patents or others, if obtained, will afford us substantial protection or commercial benefit. Similarly, there is no assurance that our pending patent applications or patent applications licensed from third parties will ultimately be granted as patents or that those patents that have been issued or are issued in the future will stand if they are challenged in court. We assess our license agreements on an ongoing basis, and may from time to time terminate licenses to technology that we do not intend to employ in our technology platforms, or in our product discovery or development activities.

MirImmune Inc. In March 2015, RXi granted an exclusive license to MirImmune to utilize the Company’s novel and proprietary sd-rxRNA technology for MirImmune’s use in developing ex vivo cell-based cancer immunotherapies to target immune inhibitory pathways (checkpoints) which are responsible for limiting the efficacy of cancer immunotherapies. Under the terms of the agreement, MirImmune was responsible for all research, development, manufacturing, regulatory and commercialization activities for the licensed products.

On October 7, 2016, RXi entered into an exclusive option agreement pursuant to which the Company had the exclusive option, but not the obligation, to purchase 100% of the outstanding capital stock of MirImmune. In January 2017, the Company exercised the option and entered into the Stock Purchase Agreement pursuant to which it acquired 100% of the outstanding shares of capital stock of MirImmune for an aggregate of 2,750,371 shares of common stock of the Company and 1,118,224 shares of Series C Convertible Preferred Stock. On June 9, 2017, with the approval of the Company’s stockholders in accordance with the stockholder approval requirements of Nasdaq Marketplace Rule 5635, each share of the Company’s Series C Convertible Preferred Stock outstanding was automatically converted into one share of common stock, such that no shares of Series C Convertible Preferred Stock remained issued or outstanding.

Upon execution of the license agreement, RXi was issued shares of common stock of Thera and was granted a five year warrant to purchase additional shares of common stock of Thera pursuant to the terms of the license agreement. The Company is eligible to receive future cash, additional equity and royalties based on the achievement of certain milestones.

Research and Development

To date, our research programs have primarily focused on developing technology necessary to make RNAi compounds available by local administration for diseases for which we intend to develop an RNAi therapeutic, identifying and testing RNAi compounds against therapeutically relevant targets in the fields of dermatology and ophthalmology and identifying lead product candidates and moving those product candidates into the clinic. With our recent acquisition of MirImmune, our research programs will also focus on developing, identifying and testing RNAi therapeutics in the field of cell-based cancer immunotherapy. Since we commenced operations, research and development has composed a significant proportion of our total operating expenses and is expected to compose the majority of our spending for the foreseeable future.

There are risks in any new field of drug discovery that preclude certainty regarding the successful development of a product. We cannot reasonably estimate or know the nature, timing and costs of the efforts necessary to complete the development of, or the period in which material net cash inflows are expected to commence from, any product candidate. Our inability to make these estimates results from the uncertainty of numerous factors, including but not limited to:

 

•

Our ability to advance product candidates into preclinical research and clinical trials;

 

•

The scope and rate of progress of our preclinical program and other research and development activities;

 

•

The scope, rate of progress and cost of any clinical trials we commence;

 

•

The cost of filing, prosecuting, defending and enforcing patent claims and other intellectual property rights;

 

•

Clinical trial results;

 

•

The terms and timing of any collaborative, licensing and other arrangements that we may establish;

 

•

The cost and timing of regulatory approvals;

 

•

The cost of establishing clinical and commercial supplies of our product candidates and any products that we may develop;

 

•

The cost and timing of establishing sales, marketing and distribution capabilities;

 

•

The effect of competing technological and market developments; and

 

•

The effect of government regulation and insurance industry efforts to control healthcare costs through reimbursement policy and other cost management strategies.

Failure to complete any stage of the development of our product candidates in a timely manner could have a material adverse effect on our operations, financial position and liquidity.

Research and Development Expense

Research and development expense consists of compensation-related costs for our employees dedicated to research and development activities, fees related to our Scientific Advisory Board members, expenses related to our ongoing research and development efforts primarily related to our clinical trials, drug manufacturing, outside contract services, licensing and patent fees and laboratory supplies and services for our research programs. We expect research and development expenses to increase as we expand our discovery, preclinical and clinical activities.

Total research and development expense for the six months ended June 30, 2017 and 2016 was $2,676,000 and $2,644,000, respectively.

Total research and development expense for the years ended December 31, 2016 and 2015 was $5,415,000 and $6,925,000, respectively.

Competition

We believe that numerous companies are investigating or plan to investigate a variety of proposed anti-scarring therapies or cell-based immunotherapies in clinical trials or are working in the RNAi area generally. Many other companies are pursuing non-RNAi-based therapies for one or more fibrotic disease indications, including ocular scarring or other indications that we may seek to pursue. The companies include large and small pharmaceuticals, chemical and biotechnology companies, as well as universities, government agencies and other private and public research organizations.

We believe that other companies currently developing anti-scarring therapies, both dermal and ocular, include CoDa Therapeutics, Inc., Sirnaomics, Inc., FirstString Research, Inc., Promedior, Inc., FibroGen, Inc., miRagen Therapeutics, Inc., Ophthotech Corporation, Vascular BioSciences, Allergan plc, and Suneva Medical, Inc.

We believe that other companies currently developing cell-based cancer immunotherapies include Juno Therapeutics, Inc., Kite Pharma, Inc., Cellectis S.A., Adaptimmune Therapeutics plc, Lion Biotechnologies, Inc., Bellicum Pharmaceuticals, Inc., and NantKwest, Inc. Many larger pharmaceutical companies such as Novartis International AG, Celgene Corporation, Pfizer Inc., GlaxoSmithKline plc, Amgen, Inc., Johnson & Johnson and EMD Serono, Inc. have entered the field through major deals with biotechnology companies and academia.

We believe that other companies working in the RNAi area, generally, include Alnylam Pharmaceuticals, Inc., Benitec Biopharma Limited, Silence Therapeutics plc, Quark Pharmaceuticals, Inc., Arbutus Biopharma Corporation, Arrowhead Pharmaceuticals, Inc., Dicerna Pharmaceuticals, Inc., Sylentis, S.A. and Roche Innovation Center Copenhagen A/S, as well as a number of large pharmaceutical companies.

We do not believe that there are any companies developing treatments for cutaneous warts that would be considered direct competitors with the Company; however, there are several existing treatments for cutaneous warts with which Samcyprone™ could potentially compete. Current topical medicinal treatments for warts include salicylic acid, off label use of Imiquimod and Picato^® and the most common ablative treatments include removal through medical procedures, such as cryotherapy, surgery or chemical peels.

Government Regulation

The United States and many other countries extensively regulate the preclinical and clinical testing, manufacturing, labeling, storage, record-keeping, advertising, promotion, export, marketing and distribution of drugs and biologic products. The FDA regulates pharmaceutical and biologic products under the Federal Food, Drug, and Cosmetic Act, the Public Health Service Act and other federal statutes and regulations.

To obtain approval of our future product candidates from the FDA, we must, among other requirements, submit data supporting safety and efficacy for the intended indication as well as detailed information on the manufacture and composition of the product candidate. In most cases, this will require extensive laboratory tests and preclinical and clinical trials. The collection of these data, as well as the preparation of applications for review by the FDA involve significant time and expense. The FDA also may require post-marketing testing to monitor the safety and efficacy of approved products or place conditions on any approvals that could restrict the therapeutic claims and commercial applications of these products. Regulatory authorities may withdraw product approvals if we fail to comply with regulatory standards or if we encounter problems at any time following initial marketing of our products.

The first stage of the FDA approval process for a new biologic or drug involves completion of preclinical studies and the submission of the results of these studies to the FDA. These data, together with proposed clinical protocols, manufacturing information, analytical data and other information submitted to the FDA in an IND application, must become effective before human clinical trials may commence. Preclinical studies generally involve FDA regulated laboratory evaluation of product characteristics and animal studies to assess the efficacy and safety of the product candidate.

After the IND becomes effective, a company may commence human clinical trials. These are typically conducted in three sequential phases, but the phases may overlap. Phase 1 trials consist of testing the product candidate in a small number of patients or healthy volunteers, primarily for safety at one or more doses. Phase 2 trials, in addition to safety, evaluate the efficacy of the product candidate in a patient population somewhat larger than Phase 1 trials. Phase 3 trials typically involve additional testing for safety and clinical efficacy in an expanded population at multiple test sites. A company must submit to the FDA a clinical protocol, accompanied by the approval of the Institutional Review Board (“IRB”) at the institutions participating in the trials, prior to commencement of each clinical trial.

To obtain FDA marketing authorization, a company must submit to the FDA the results of the preclinical and clinical testing, together with, among other things, detailed information on the manufacture and composition of the product candidate, in the form of a new drug application (an “NDA”), or, in the case of a biologic, a biologics license application (a “BLA”).

The amount of time taken by the FDA for approval of an NDA or BLA will depend upon a number of factors, including whether the product candidate has received priority review, the quality of the submission and studies presented, the potential contribution that the compound will make in improving the treatment of the disease in question and the workload at the FDA.

The FDA may, in some cases, confer upon an investigational product the status of a fast track product. A fast track product is defined as a new drug or biologic intended for the treatment of a serious or life threatening condition that demonstrates the potential to address unmet medical needs for this condition. The FDA can base approval of an NDA or BLA for a fast track product on an effect on a surrogate endpoint, or on another endpoint that is reasonably likely to predict clinical benefit. If a preliminary review of clinical data suggests that a fast track product may be effective, the FDA may initiate review of entire sections of a marketing application for a fast track product before the sponsor completes the application.

Table of Contents

We anticipate that our products will be manufactured by our strategic partners, licensees or other third parties. Before approving an NDA or BLA, the FDA will inspect the facilities at which the product is manufactured and will not approve the product unless the manufacturing facilities are in compliance with the FDA’s current good manufacturing practices (“cGMP”), which are regulations that govern the manufacture, holding and distribution of a product. Manufacturers of biologics also must comply with the FDA’s general biological product standards. Our manufacturers also will be subject to regulation under the Occupational Safety and Health Act, the Nuclear Energy and Radiation Control Act, the Toxic Substance Control Act and the Resource Conservation and Recovery Act and other applicable environmental statutes. Following approval, the FDA periodically inspects drug and biologic manufacturing facilities to ensure continued compliance with the cGMP. Our manufacturers will have to continue to comply with those requirements. Failure to comply with these requirements subjects the manufacturer to possible legal or regulatory action, such as suspension of manufacturing or recall or seizure of product. Adverse patient experiences with the product must be reported to the FDA and could result in the imposition of marketing restrictions through labeling changes or market removal. Product approvals may be withdrawn if compliance with regulatory requirements is not maintained or if problems concerning safety or efficacy of the product occur following approval.

The labeling, advertising, promotion, marketing and distribution of a drug or biologic product also must be in compliance with FDA and Federal Trade Commission requirements which include, among others, standards and regulations for off-label promotion, industry sponsored scientific and educational activities, promotional activities involving the internet, and direct-to-consumer advertising. We also will be subject to a variety of federal, state and local regulations relating to the use, handling, storage and disposal of hazardous materials, including chemicals and radioactive and biological materials. In addition, we will be subject to various laws and regulations governing laboratory practices and the experimental use of animals. In each of these areas, as above, the FDA has broad regulatory and enforcement powers, including the ability to levy fines and civil penalties, suspend or delay issuance of product approvals, seize or recall products and deny or withdraw approvals.

We will also be subject to a variety of regulations governing clinical trials and sales of our products outside the United States. Whether or not FDA approval has been obtained, approval of a product candidate by the comparable regulatory authorities of foreign countries and regions must be obtained prior to the commencement of marketing the product in those countries. The approval process varies from one regulatory authority to another and the time may be longer or shorter than that required for FDA approval. In the European Union, Canada and Australia, regulatory requirements and approval processes are similar, in principle, to those in the United States.

Environmental Compliance

Our research and development activities involve the controlled use of potentially harmful biological materials as well as hazardous materials, chemicals and various radioactive compounds. We are subject to federal, state and local laws and regulations governing the use, storage, handling and disposal of these materials and specific waste products. We are also subject to numerous environmental, health and workplace safety laws and regulations, including those governing laboratory procedures, exposure to blood-borne pathogens and the handling of bio-hazardous materials. The cost of compliance with these laws and regulations could be significant and may adversely affect capital expenditures to the extent we are required to procure expensive capital equipment to meet regulatory requirements.

Employees

As of August 8, 2017, we had sixteen full-time employees, nine of whom were engaged in research and development, and seven of whom were engaged in management, administration and finance. None of our employees are represented by a labor union or covered by a collective bargaining agreement nor have we experienced any work stoppages.    

Properties

Our executive offices are located at 257 Simarano Drive, Suite 101, Marlborough, MA 01752. On December 17, 2013, we entered into a lease (the “Lease”) with 257 Simarano Drive, LLC, Brighton Properties, LLC, Robert Stubblebine 1, LLC and Robert Stubblebine 2, LLC to lease office and laboratory space in the building known as the “Main Building” located at 257 Simarano Drive, Marlborough, Massachusetts, covering approximately 7,581 square feet. The premises are used by the Company for office and laboratory space. The term of the Lease commenced on April 1, 2014 and continues for five years, expiring on March 31, 2019. The base rent for the premises during the first year of the Lease was $107,709.50 per annum, payable monthly. Each year thereafter, the base rent increases by approximately 3% over the base rent from the prior year.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of our financial condition and results of operations should be read in conjunction with our financial statements and the notes to those financial statements included elsewhere in this prospectus. This discussion contains forward-looking statements that involve significant risks and uncertainties. As a result of many factors, such as those set forth under “Risk Factors” and elsewhere in this prospectus, our actual results may differ materially from those anticipated in these forward-looking statements. Please refer to the discussion under the heading “Cautionary Note Regarding Forward-Looking Statements” above.

Overview

RXi Pharmaceuticals Corporation (“RXi,” “we,” “our” or the “Company”) is a clinical-stage company developing innovative therapeutics based on our proprietary self-delivering RNAi (sd-rxRNA^®) platform and Samcyprone™ which address significant unmet medical needs. We have a pipeline of discovery, preclinical and clinical product candidates in the areas of dermatology, ophthalmology and cell-based cancer immunotherapy. The Company’s clinical development programs include RXI-109, an sd-rxRNA for the treatment of dermal and ocular scarring, and Samcyprone™, a topical immunomodulator, for the treatment of warts. The Company’s pipeline, coupled with our extensive patent portfolio, provides for product development and business development opportunities across a broad spectrum of therapeutic areas.

RNAi therapies are designed to “silence,” or down-regulate, the expression of a specific gene that may be over-expressed in a disease condition. The Company’s first RNAi clinical product candidate, RXI-109, is a self-delivering RNAi compound (sd-rxRNA) that commenced human clinical trials in 2012. RXI-109 is designed to reduce the expression of connective tissue growth factor (“CTGF”), a critical regulator of several biological pathways involved in fibrosis, including scar formation in the skin and eye. RXI-109 is currently being evaluated in a Phase 2 clinical trial, Study 1402, to prevent or reduce dermal scarring following scar revision surgery of an existing hypertrophic scar and a Phase 1/2 clinical trial, Study 1501, to evaluate the safety and clinical activity of RXI-109 to prevent the progression of retinal scarring in subjects with wet age-related macular degeneration (“AMD”).

Study 1402, the Company’s Phase 2 clinical trial in hypertrophic scars, commenced in July 2014. In October 2015, we reported that preliminary data from Study 1402 demonstrated that scars at revision sites were judged to be better at three months after a treatment regimen with five mg/cm intradermal administration of RXI-109 than scars at untreated revision sites in those same subjects. Based in part on this new information, two more cohorts (Cohorts 3 and 4) were added to Study 1402 in November 2015. For these two cohorts, the number of doses was increased to either eight or nine doses of RXI-109 over a six-month period to better cover the extended wound healing/scarring profile of hypertrophic scars. Enrollment of subjects into these two new cohorts completed ahead of schedule during the third quarter of 2016.

In December 2016, the Company announced that preliminary data from the first two cohorts from Study 1402 at nine months confirmed the positive differentiation by a blinded panel of observers from untreated surgery incisions in hypertrophic scars from the previously presented data for a subset of subjects treated with five mg/cm of RXI-109 at three months. In addition, these data extend this observation to all time points, including the post-treatment follow-up period through nine months post-surgery. RXI-109 was safe and well tolerated. Additionally, as expected, the limited three-month data available from Cohort 3 appeared to align with that of the first two cohorts as these subjects all had the same dosing schedule through the third month. A complete read-out of the whole study, including all four cohorts with follow-up until nine months post-surgery, is expected in the second half of 2017.

Study 1501, the Company’s Phase 1/2 clinical trial in retinal scars, commenced in November 2015, and is a multi-dose, dose escalation study conducted in subjects with AMD with evidence of subretinal fibrosis. Each subject receives four doses of RXI-109 by intraocular injection at one month intervals for a total dosing period of three months. The safety and tolerability of RXI-109, as well as the potential for clinical activity, is evaluated over the course of the study using numerous assessments to monitor the health of the retina and to assess visual acuity. To date, there have been no safety issues that have precluded continuation of dosing. Study 1501 has been completely enrolled and dosing in the third cohort at the highest planned dose level is ongoing. The Company expects to complete subject participation in the study by the end of 2017 and to share top-line data in early 2018.

Samcyprone™, the Company’s second clinical candidate, is a proprietary topical formulation of the small molecule diphenylcyclopropenone (“DPCP”), an immunomodulator that works by initiating a T-cell response. The use of Samcyprone™ allows sensitization using much lower concentrations of DPCP than are used with existing compounded DPCP solutions, avoiding hyper-sensitization to subsequent challenge doses. Samcyprone™ is currently being evaluated in a Phase 2a clinical trial, Study 1502, for the clearance of common warts.

Table of Contents

Study 1502, initiated in December 2015, includes a sensitization phase in which a spot on the subject’s upper arm and one or more warts are treated with Samcyprone™. After being sensitized in this way, the subjects enter into the treatment phase where up to four warts are treated on a once weekly basis for ten weeks with a ten-fold lower concentration of Samcyprone™ than in the sensitization phase. During the trial, the warts are scored, photographed and measured to monitor the level of clearance.

In December 2016, the Company announced the results from a preliminary review of sensitization and wart clearance data from a subset of subjects that had completed the ten-week treatment phase of Study 1502. Results showed that greater than 90% of the subjects demonstrated a sensitization response, a prerequisite to be able to develop a therapeutic response. Additionally, more than 60% of the subjects responded to the treatment by exhibiting either complete or greater than 50% clearance of all treated warts with up to ten weekly treatments. Samcyprone™ treatment has been generally safe and well tolerated and has had drug-related adverse events relating to local reactions, which are typically expected for this type of treatment due to the sensitization and challenge responses in the skin. The Company added a second cohort, which is expected to be fully enrolled in the second half of 2017, to explore the opportunity to reduce the sensitization dose level, which will be more convenient to physicians and subjects. Early read-outs of the study are anticipated in the second half of 2017.

In addition to our clinical programs, we continue to advance our preclinical and discovery programs with our sd-rxRNA technology. In October 2015, we announced the selection of lead compounds targeting tyrosinase (“TYR”) and collagenase (“MMP1”) as targets for our self-delivering platform because they are relevant for both consumer health and therapeutic development. Cosmetics are compounds that affect the appearance of the skin and make no preventative or therapeutic claims. These compounds may be developed more rapidly than therapeutics, therefore the path to market may be much shorter and less expensive. RXI-231, an sd-rxRNA compound targeting TYR, is in development as a cosmetic ingredient that may improve the appearance of uneven skin tone and pigmentation. RXI-185, an sd-rxRNA compound targeting MMP1, is in development as a cosmetic ingredient that may improve the appearance of wrinkles or skin laxity. Efficacy and toxicity testing in cell culture and skin equivalents for RXI-231 was successfully completed in December 2016. The Company initiated human testing of RXI-231 in June 2017 with a U.S. clinical testing site. In addition to evaluating safety, the Company will assess the effect of RXI-231 on the appearance of skin pigmentation in a follow-on study.

On April 14, 2016, the Board of Directors of the Company approved a 1-for-10 reverse stock split of the Company’s outstanding common stock, which was effected on April 18, 2016. The number of authorized shares of the Company remain unchanged. Stockholders who would have otherwise been entitled to fractional shares as a result of the reverse stock split received a cash payment in lieu of receiving fractional shares. Shares of common stock underlying outstanding stock options and other equity instruments were proportionately reduced and the respective exercise prices, if applicable, were proportionately increased in accordance with the terms of the agreements governing such securities. All share and per share amounts in the financial statements have been retroactively adjusted for all periods presented to give effect to the reverse stock split, including reclassifying an amount equal to the reduction in par value to additional paid-in capital.

On December 21, 2016, the Company closed an underwritten public offering (the “2016 Offering”) of (i) 3,797,777 Class A Units, at a public offering price of $0.90 per unit, consisting of one share of the Company’s common stock and a five-year warrant to purchase one share of common stock at an exercise price of $0.90 per share (the “2016 Warrants”) and (ii) 8,082 Class B Units, at a public offering price of $1,000 per unit, consisting of one share of Series B Convertible Preferred Stock (the “Series B Convertible Preferred Stock”), which was convertible into 1,111.11 shares of common stock, and 1,111.11 2016 Warrants. The Class A Units include an additional 1,666,666 Class A Units pursuant to the exercise by the underwriters of their over-allotment option. The total net proceeds of the 2016 Offering, including the exercise of the over-allotment option, were $10,051,000 after deducting underwriting discounts and commissions and offering expenses paid by the Company.

On January 6, 2017, the Company entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) by and among the Company, RXi Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company (“RXi Merger Sub”), MirImmune Inc. (“MirImmune”), the stockholders of MirImmune set forth on the signature pages thereto (each a “Seller” and collectively, the “Sellers”), and Alexey Wolfson, Ph.D., in his capacity as the Sellers’ Representative. Pursuant to the Stock Purchase Agreement, the Company acquired from the Sellers all of the issued and outstanding shares of capital stock of MirImmune for an aggregate of 2,750,371 shares of common stock of the Company and an aggregate of 1,118,224 shares of Series C Convertible Preferred Stock (the “Series C Convertible Preferred Stock”). On June 9, 2017, with the approval of the Company’s stockholders in accordance with the stockholder approval requirements of Nasdaq Marketplace Rule 5635, each share of the Company’s Series C Convertible Preferred Stock outstanding was automatically converted into one share of common stock, such that no shares of Series C Convertible Preferred Stock remained issued or outstanding.

Table of Contents

In connection with and promptly following the closing of the Stock Purchase Agreement, MirImmune was merged with and into RXi Merger Sub (the “Merger”), with RXi Merger Sub continuing as the surviving entity and changing its name to “MirImmune, LLC”. As a result of the Merger, MirImmune, LLC remains and will operate as a wholly-owned subsidiary of the Company.

Building on the work completed by MirImmune prior to its acquisition by the Company, our cell-based cancer immunotherapy program with sd-rxRNA includes lead compounds for a number of immune checkpoint targets that provide long lasting immune checkpoint silencing, individually and in combination, in adoptively transferred cells. An improved efficacy upon the silencing of checkpoints has been demonstrated in various types of adoptively transferred cells relevant in cancer immunotherapy, such as CAR T-cells and tumor infiltrating lymphocytes (TILs). The Company’s ongoing discovery programs include, but are not limited to, the evaluation of sd-rxRNA compounds to silence targets related to cytokine release syndrome. The Company has also initiated in vivo evaluations of multiple checkpoint inhibiting sd-rxRNA compounds co-transfected in CAR T-cells in mouse models for solid tumors, with data from this study expected in the second half of 2017.

Additionally, the Company recently selected two sd-rxRNA compounds from its immunotherapy pipeline for preclinical development. For oncology treatments based on adoptive cell transfer (ACT), compounds RXI-762 and RXI-804 suppress the expression of immune checkpoint proteins PD-1 and TIGIT, respectively, which can result in an improved efficacy to the targeted tumors. This decision triggered the selection of a manufacturing facility to initiate production of cGMP grade material, initially for the first of these two compounds (RXI-762). This also supports moving RXI-762 into clinical development as early as 2018 as part of an ACT therapy.

On August 8, 2017, the Company entered into a purchase agreement (the “Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”), pursuant to which the Company has the right to sell to Lincoln Park up to $15,000,000 in shares of the Company’s common stock, subject to certain limitations and conditions set forth therein, over the 30-month term of the Purchase Agreement.

Since inception, we have incurred significant losses. Substantially all of our losses to date have resulted from research and development expenses in connection with our clinical and research programs and from general and administrative costs. At June 30, 2017 and December 31, 2016, we had an accumulated deficit of $74.1 million and $66.1 million, respectively. We expect to continue to incur significant losses for the foreseeable future, particularly as we advance our development programs for RXI-109 and Samcyprone™ and expand our program in cell-based cancer immunotherapy.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based upon our financial statements, which have been prepared in accordance with United States generally accepted accounting principles (“GAAP”). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to the impairment of long-lived assets, certain accrued expenses and stock-based compensation. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions and could have a material impact on our reported results. While our significant accounting policies are more fully described in the Notes to our financial statements included elsewhere in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2017, which was filed with the SEC on August 10, 2017 and our Annual Report on Form 10-K for the year ended December 31, 2016, which was filed with the SEC on March 30, 2017, we believe the following accounting policies to be the most critical in understanding the judgments and estimates we use in preparing our financial statements.

Research and Development Expenses

Research and development costs are charged to expense as incurred and relate to salaries, employee benefits, facility-related expenses, supplies, stock-based compensation related to employees and non-employees involved in the Company’s research and development, external services, other operating costs and overhead related to our research and development departments, costs to acquire technology licenses and expenses associated with preclinical activities and our clinical trials.

Table of Contents

Preclinical and clinical trial expenses relate to third-party services, subject-related fees at the sites where our clinical trials are being conducted, laboratory costs, analysis costs, toxicology studies and investigator fees. Costs associated with these expenses are generally payable on the passage of time or when certain milestones are achieved. Expense is recorded during the period incurred or in the period in which a milestone is achieved. In order to ensure that we have adequately provided for preclinical and clinical expenses during the proper period, we maintain an accrual to cover these expenses. These accruals are assessed on a quarterly basis and are based on such assumptions as expected total cost, the number of subjects and clinical trial sites and length of the study. Actual results may differ from these estimates and could have a material impact on our reported results. Our historical accrual estimates have not been materially different from our actual costs.

Stock-based Compensation

The Company follows the provisions of the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC”) Topic 718, “Compensation – Stock Compensation” (“ASC 718”), which requires the measurement and recognition of compensation expense for all stock-based payment awards made to employees, officers and non-employee directors, including stock options. Stock compensation expense based on the grant date fair value estimated in accordance with the provisions of ASC 718 is recognized as an expense over the requisite service period. Determining the amount of stock-based compensation to be recorded requires us to develop highly subjective estimates to be used in calculating the grant-date fair value of stock options. We use the Black-Scholes option pricing model to value our option grants and determine the related compensation expense. The use of the model requires us to make estimates of the following assumptions:

Expected volatility — Due to our limited trading history, we are responsible for estimating volatility and currently use the expected volatilities of similar entities. We have considered a number of factors in making our determination as to entities that are considered similar, such as the industry, stage of development, size of the company, and financial leverage.

Expected term — We use the simplified method to estimate the expected term assumption. The simplified method is based on the vesting period and the contractual term for each grant, or for each vesting-tranche for awards with graded vesting.

Risk-free interest rate — The yield on zero-coupon U.S. Treasury securities for a period that is commensurate with the expected term assumption is used as the risk-free interest rate.

Dividend yield — We utilize a dividend yield of zero based on the fact that we have never paid cash dividends and currently have no intention to pay cash dividends.

For stock options granted as consideration for services rendered by non-employees, the Company recognizes compensation expense in accordance with the requirements of FASB ASC Topic 505-50, “Equity Based Payments to Non-Employees.” Non-employee option grants that do not vest immediately upon grant are recorded as an expense over the requisite service period of the underlying stock options. At the end of each financial reporting period prior to vesting, the value of these options, as calculated using the Black-Scholes option-pricing model, will be re-measured using the fair value of the Company’s common stock and the non-cash compensation recognized during the period will be adjusted accordingly. Since the fair market value of options granted to non-employees is subject to change in the future, the amount of the future compensation expense will include fair value re-measurements until the stock options are fully vested.

Derivative Financial Instruments

During the normal course of business we may issue warrants to vendors as consideration to perform services. We may also issue warrants as part of a debt or equity financing. Warrants and other derivative financial instruments are accounted for either as equity or as an asset or liability, depending on the characteristics of each derivative financial instrument. Warrants classified as equity are measured at fair value and recorded as additional paid in capital in stockholders’ equity at the date of issuance. No further adjustments to their valuation are made. Derivative financial instruments classified as an asset or liability are measured at fair value on the issuance date and are revalued on each subsequent balance sheet date. The changes in the fair value are recognized as current period income or loss.

Research and Development Expenses

Research and development expenses were approximately $5,415,000 for the year ended December 31, 2016, compared with $6,925,000 for the year ended December 31, 2015. The decrease of $1,510,000, or 22%, was due to a decrease of $1,121,000 in research and development expense primarily related to cash and equity fees payable to Hapten Pharmaceuticals, LLC upon the close of the Samcyprone™ license agreement and manufacturing expenses for the RXI-109 drug product, which both occurred in 2015. An additional decrease of $389,000 in stock-based compensation expense was due to the full vesting of stock options in 2016 from stock options that were granted in 2012.    

General and Administrative Expenses

General and administrative expenses were approximately $3,619,000 for the year ended December 31, 2016, compared with $3,346,000 for the year ended December 31, 2015.

These increases were offset by a decrease of $390,000 in stock-based compensation expense due to the full vesting of stock options in 2016 from stock options that were granted in 2012.

Accretion of convertible preferred stock and dividends was approximately $2,075,000 for the year ended December 31, 2016, compared with $209,000 for the year ended December 31, 2015. In connection with the completion of the Company’s public offering in December 2016, the Company issued shares of Series B Convertible Preferred Stock (the “Series B Convertible Preferred Stock”). The increase of $1,866,000 was due to the one-time charge of $2,075,000 related to the beneficial conversion feature of the Series B Convertible Preferred Stock offset by a decrease of $209,000 related to the fair value of dividends on the Company’s Series A and Series A-1 Convertible Preferred Stock (the “Series A and Series A-1 Convertible Preferred Stock”).

All shares of the Series A and Series A-1 Convertible Preferred Stock were fully converted during the quarter ended June 30, 2015, resulting in no further accumulation and payment of dividends on these series of preferred stock. In November 2015, the Company filed a Certificate Eliminating the Series A Convertible Preferred Stock and a Certificate Eliminating the Series A-1 Convertible Preferred Stock from the Certificate of Incorporation of the Company with the Secretary of State of the State of Delaware. As a result, the shares of unissued Series A and Series A-1 Convertible Preferred Stock were returned to the status of authorized but unissued shares of preferred stock of the Company, without designation as to series or preferences or rights.

Liquidity and Capital Resources

On December 18, 2014, the Company entered into a purchase agreement (the “2014 Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”), pursuant to which the Company had the right to sell to Lincoln Park up to $10.8 million in shares of the Company’s common stock, subject to certain limitations and conditions set forth in the 2014 Purchase Agreement. The 2014 Purchase Agreement expired on April 17, 2017. Under the 2014 Purchase Agreement, the Company sold a total of 70,000 shares of common stock to Lincoln Park for net proceeds of approximately $216,000.

On June 2, 2015, we sold 2,600,000 units in a public offering at a price of $4.00 per unit (the “2015 Offering”). Each unit consisted of one share of common stock, a 13-month overallotment purchase right to purchase one-half of one share of common stock at a price of $4.55 per full share of common stock (the “Overallotment Purchase Rights”) and a five-year warrant to purchase one-half of one share of common stock at a price of $5.20 per full share of common stock (the “2015 Warrants”). As a result of the 2015 Offering, the Company received net proceeds of approximately $9,200,000 after placement agent fees and offering expenses.

Overallotment Purchase Rights totaling 1,300,002 were issued in connection with the 2015 Offering. During the year ended December 31, 2015, 43,500 Overallotment Purchase Rights were exercised for gross proceeds of $198,000. The Company’s remaining outstanding Overallotment Purchase Rights of 1,256,502 expired on July 2, 2016 and were not exercised.

On December 21, 2016, the Company closed an underwritten public offering (the “2016 Offering”) of (i) 3,797,777 Class A Units, at a public offering price of $0.90 per unit, consisting of one share of the Company’s common stock and a five-year warrant to purchase one share of common stock at an exercise price of $0.90 per share (the “Warrants”) and (ii) 8,082 Class B Units, at a public offering price of $1,000 per unit, consisting of one share of Series B Convertible Preferred Stock (the “Series B Convertible Preferred Stock”), which was convertible into 1,111.11 shares of common stock, and 1,111.11 Warrants. The Class A Units include an additional 1,666,666 Class A Units pursuant to the exercise by the underwriters of their over-allotment option. The total net proceeds of the 2016 Offering, including the exercise of the over-allotment option, were $10,051,000 after deducting underwriting discounts and commissions and offering expenses paid by the Company.

On August 8, 2017, the Company entered into a purchase agreement (the “2017 Purchase Agreement”) with Lincoln Park, pursuant to which the Company has the right to sell to Lincoln Park up to $15,000,000 in shares of the Company’s common stock, subject to certain limitations and conditions set forth therein, over the 30-month term of the 2017 Purchase Agreement.

We had cash of $7.7 million as of June 30, 2017, compared with cash of $12.9 million as of December 31, 2016. The Company believes that its existing cash, and the potential proceeds available under our equity facility with Lincoln Park, should be sufficient to fund the Company’s operations for at least the next twelve months. We have generated significant losses to date, have not generated any product revenue to date and may not generate product revenue in the foreseeable future, or ever. We expect to incur significant operating losses as we advance our product candidates through drug development and the regulatory process. In the future, we will be dependent on obtaining funding from third parties, such as proceeds from the issuance of debt, sale of equity, funded research and development programs and payments under partnership and collaborative research and business development agreements, in order to maintain our operations and meet our obligations to licensors. There is no guarantee that debt, additional equity or other funding will be available to us on acceptable terms, or at all. If we fail to obtain additional funding when needed, we would be forced to scale back or terminate our operations or to seek to merge with or to be acquired by another company.

Director Independence

We believe that the Company benefits from having a strong and independent Board. For a director to be considered independent, the Board must determine that the director does not have any direct or indirect material relationship with the Company that would affect his or her exercise of independent judgment. On an annual basis, the Board reviews the independence of all directors under the applicable NASDAQ listing standards. The Company also considers each director’s affiliations with the Company and members of management, as well as significant holdings of Company securities. This review considers all known relevant facts and circumstances in making an independence determination. Based on this review, the Board has made an affirmative determination that all directors, other than Dr. Cauwenbergh, are independent. It was determined that Dr. Cauwenbergh lacks independence because of his status as the Company’s President and Chief Executive Officer.

In addition, NASDAQ listing standards require that, subject to specified exceptions, each member of our Audit, Compensation and Nominating and Governance Committees be independent and that our Audit Committee members also satisfy independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Our Board has determined that Messrs. Brownlie and Dorman and Dr. Freeman, members of the Audit Committee, Messrs. Bitterman and Brownlie and Dr. Lockshin, members of the Compensation Committee, and Drs. Lockshin and Freeman and Messr. Dorman, members of the Nominating and Governance Committee, are independent under the applicable NASDAQ listing standards and the Exchange Act.

SECURITY OWNERSHIP OF BENEFICIAL OWNERS AND MANAGEMENT

Based on information available to us and filings with the Securities and Exchange Commission (the “SEC”), the following table sets forth certain information regarding the beneficial ownership (as defined by Rule 13d-3 under the Securities Exchange Act of 1934) of our outstanding common stock for (i) each of our directors, (ii) each of our “named executive officers,” as defined in the Executive Compensation section above, (iii) all of our directors and executive officers as a group and (iv) persons known to us to beneficially own more than 5% of our outstanding common stock. The following information is presented as of August 10, 2017 or such other date as may be reflected below.

Beneficial ownership and percentage ownership are determined in accordance with the rules of the SEC and include voting or investment power with respect to shares of stock. This information does not necessarily indicate beneficial ownership for any other purpose. Under these rules, shares of common stock issuable under stock options or warrants that are exercisable within 60 days of August 10, 2017 are deemed outstanding for the purpose of computing the percentage ownership of the person holding the options or warrants, but are not deemed outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated and subject to applicable community property laws, to our knowledge, each stockholder named in the following table possesses sole voting and investment power over their shares of common stock, except for those jointly owned with that person’s spouse. Unless otherwise indicated below, the address of each person listed on the table is c/o RXi Pharmaceuticals Corporation, 257 Simarano Drive, Suite 101, Marlborough, MA 01752.

CERTAIN RELATIONSHIPS AND RELATED-PARTY TRANSACTIONS

Since the past two years, there has not been, nor is there currently proposed, any transaction or series of related transactions to which we were or will be a party in which the amount involved exceeded or will exceed $120,000 and in which the other parties included or will include any of our directors, executive officers, holders of 5% or more of our voting securities, or any member of the immediate family of any of the foregoing persons, other than compensation arrangements with directors and executive officers, which are described where required in “Directors, Executive Officers, Promotors and Control Persons,” “Executive Compensation,” and the transactions described below.

Procedures for Review, Approval or Ratification of Transactions with Related Persons

Our Board of Directors has a policy to review and approve all transactions with directors, officers and holders of more than 5% of our voting securities and their affiliates. The policy provides that, prior to Board consideration of a transaction with such a related party, the material facts as to the related party’s relationship or interest in the transaction must be disclosed to the Board, and the transaction will not be considered approved by the Board unless a majority of the directors who are not interested in the transaction (if applicable) approve the transaction. Furthermore, when stockholders are entitled to vote on a transaction with a related party, the material facts of the related party’s relationship or interest in the transaction must be disclosed to the stockholders, who must approve the transaction in good faith.    

Indemnification Agreements

We have entered into indemnification agreements with each of our executive officers and directors. These agreements provide that, subject to limited exceptions and among other things, we will indemnify each of our executive officers and directors to the fullest extent permitted by law and advance expenses to each indemnitee in connection with any proceeding in which a right to indemnification is available.

Stock Purchase Agreement

On January 6, 2017, the Company entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) by and among the Company, RXi Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company (“RXi Merger Sub”), MirImmune Inc., a Delaware corporation (“MirImmune”), the stockholders of MirImmune set forth on the signature pages thereto (each a “Seller” and collectively, the “Sellers”), and Alexey Wolfson, Ph.D., in his capacity as the Sellers’ Representative. Pursuant to the Stock Purchase Agreement, the Company acquired from the Sellers 100% of the issued and outstanding shares of capital stock of MirImmune for an aggregate of 2,750,371 shares of the Company’s common stock and an aggregate of 1,118,224 shares of Series C Convertible Preferred Stock, par value $0.0001 per share (the “Series C Convertible Preferred Stock”). Such consideration represents in the aggregate a number of shares of capital stock equal to approximately 19.99% of the outstanding common stock immediately prior to the execution of the Stock Purchase Agreement, plus approximately 19.99% of the common stock underlying the outstanding Series B Convertible Preferred Stock immediately prior to the execution of the Stock Purchase Agreement, which was previously issued in the Company’s registered securities offering pursuant to a registration statement on Form S-1 (File No. 333-214199) (the “Financing”). On June 9, 2017, with the approval of the Company’s stockholders in accordance with the stockholder approval requirements of Nasdaq Marketplace Rule 5635, each share of the Company’s Series C Convertible Preferred Stock outstanding was automatically converted into one share of common stock, such that no shares of Series C Convertible Preferred Stock remained issued or outstanding.

Under the terms of the Stock Purchase Agreement, if certain development or commercial milestones (the “Milestones”) are achieved within two years of the Closing (as defined therein), the Company will be required to either: (i) issue to the Sellers a number of shares of common stock (the “Milestone Shares”) equal to the sum of 2,519,091 shares of common stock (which represents 13% of the outstanding common stock and 13% of the common stock underlying the shares of Series B Convertible Preferred Stock, in each case as of immediately following the closing of the Financing), plus an additional number of shares of common stock equal to 13% of the common stock issued upon exercise of any warrants issued under the Financing, which would result in the issuance of a maximum of 1,661,111 additional shares of common stock, but only to the extent that such warrants have been exercised prior to the Milestones being achieved; or (ii) pay the equivalent value of the Milestone Shares in cash to the Sellers, subject to certain adjustments set forth in the Stock Purchase Agreement. In certain circumstances, if the Company has not received stockholder approval for the issuance of the Milestone Shares, the Company may be required to instead issue shares of Series C Convertible Preferred Stock in lieu of part or all of the common stock otherwise issuable as Milestone Shares.

Table of Contents

Pursuant to the Stock Purchase Agreement, we issued 817,813 shares of common stock and 332,499 shares of Series C Convertible Preferred Stock to Alexey Eliseev, Ph.D., a Seller in the agreement and co-founder of MirImmune. The approximate dollar value of such shares is equal to $0.8 million. Additionally, Dr. Eliseev is eligible to receive 748,926 Milestone Shares, or the equivalent value in cash, if the Milestones are achieved within two years. The amount of Milestone Shares to be issued may increase as provided above. Assuming no such increase takes place, the approximate dollar value of such Milestone Shares is equal to approximately $0.4 million, (based on an assumed Milestone Share price per common share of $0.595 which was the closing price of our common stock on August 17, 2017). In connection with the Stock Purchase Agreement Dr. Eliseev also executed and delivered a three-year non-compete agreement with the Company under which Dr. Eliseev agreed to not interfere with the Company’s business or solicit the Company’s employees or business contacts. Dr. Eliseev is the Chief Business Officer of the Company.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the Delaware General Corporation Law (“DGCL”) authorizes a corporation to indemnify its directors and officers against liabilities arising out of actions, suits and proceedings to which they are made or threatened to be made a party by reason of the fact that they have served or are currently serving as a director or officer to a corporation. The indemnity may cover expenses (including attorneys’ fees) judgments, fines and amounts paid in settlement actually and reasonably incurred by the director or officer in connection with any such action, suit or proceeding. Section 145 permits corporations to pay expenses (including attorneys’ fees) incurred by directors and officers in advance of the final disposition of such action, suit or proceeding. In addition, Section 145 provides that a corporation has the power to purchase and maintain insurance on behalf of its directors and officers against any liability asserted against them and incurred by them in their capacity as a director or officer, or arising out of their status as such, whether or not the corporation would have the power to indemnify the director or officer against such liability under Section 145.

Our certificate of incorporation provides that we will indemnify to the fullest extent authorized or permitted by the DGCL or any other applicable law as now or hereafter in effect any person made, or threatened to be made, a defendant or witness to any action, suit or proceeding (whether civil, criminal or otherwise) by reason of the fact that he is or was a director of our corporation or by reason of the fact that such director, at our request, is or was serving any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise in any capacity. Our certificate of incorporation also provides that no amendment or repeal of the certificate of incorporation will apply to or have any effect on any right to indemnification provided in the certificate of incorporation with respect to any acts or omissions occurring prior to such amendment or repeal.

As permitted by the DGCL, our bylaws, as amended, provide that we will indemnify to the fullest extent authorized or permitted by applicable law as now or hereafter in effect any person who was or is made, or is threatened to be made, a party or is otherwise involved in any action, suit or proceeding (whether civil, criminal, administrative or investigative), by reason of the fact that he (or a person for whom he is the legal representative) is or was a director or officer of our corporation, is or was serving at our request as a director, officer, employee, member, trustee or agent of another corporation or of a partnership, joint venture, trust, nonprofit entity or other enterprise.

Consequently, no director of the corporation will be personally liable to the corporation or its stockholders for monetary damages for any breach of fiduciary duty by such a director as a director. However, notwithstanding the preceding sentence, a director will be liable to the extent provided by Delaware law (1) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) for payments of unlawful dividends or for unlawful stock repurchases or redemption, or (4) for any transaction from which the director derived an improper personal benefit.

We have entered into indemnification agreements with each of our executive officers and directors. These agreements provide that, subject to limited exceptions and among other things, we will indemnify each of our executive officers and directors to the fullest extent permitted by law and advance expenses to each indemnitee in connection with any proceeding in which a right to indemnification is available.

We also maintain insurance on behalf of any person who is or was our director, officer, trustee, employee or agent or serving at our request as a director, officer, trustee, employee or agent of another corporation, partnership, joint venture, trust, non-profit entity or other enterprise against any liability asserted against the person and incurred by the person in any such capacity, or arising out of his or her status as such.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted for directors, officers, or persons who control us, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

In the three years preceding the filing of this Registration Statement, we have issued the following securities that were not registered in the Securities Act.

On March 20, 2015, the Company entered into an exchange agreement with Tang Capital Partners, LP (“TCP”) pursuant to which TCP exchanged a total of 2,000 shares of Series A Preferred Stock for a like number of shares of Series A-1 Preferred Stock.

With respect to the foregoing exchange agreement, the Company issued the Series A-1 Preferred Stock in transactions exempt from the registration requirements of the Securities Act by virtue of the exemption provided for in Section 3(a)(9) of the Act for securities exchanged by the issuer with an existing security holder.

On February 4, 2015, the Company issued 20,000 shares of common stock to Hapten Pharmaceuticals, LLC, pursuant to that certain Assignment and Exclusive License Agreement dated as of December 17, 2014, in partial consideration for certain patent rights and related assets and rights, including an investigational new drug application and clinical data for Hapten’s Samcyprone™ gel products for therapeutic and prophylactic use.

Holders of Series A Convertible Preferred Stock received dividends payable in shares of Series A Convertible Preferred Stock of 105 and 356 during the years ended December 31, 2015 and 2014, respectively.

Holders of Series A-1 Convertible Preferred Stock received dividends payable in shares of Series A-1 Convertible Preferred Stock of 21 and 240 during the years ended December 31, 2015 and 2014, respectively.

On January 6, 2017, the Company issued a total of 3,868,595 shares of common stock to MirImmune Inc. (“MirImmune”) pursuant to that certain Stock Purchase Agreement dated January 6, 2017, in consideration for the Company’s acquisition of MirImmune outstanding capital stock.

On August 8, 2017, The Company issued 450,000 shares of common stock, at a price per share of $0.58, to Lincoln Park Capital Fund, LLC (“Lincoln Park”) pursuant to that certain Purchase Agreement dated August 8, 2017.

On June 7, 2013, the Compensation Committee approved an employee stock purchase plan (“ESPP”), which was subsequently approved by the Company’s stockholders at the Company’s 2014 Annual Meeting of Stockholders and amended by the Company’s stockholders at the Company’s 2016 Annual Meeting of Stockholders. The ESPP allows employees to contribute a percentage of their cash earnings, subject to certain maximum amounts, to be used to purchase shares of the Company’s common stock on each of two semi-annual purchase dates. The purchase price is equal to 90% of the market value per share on either (a) the date of grant of a purchase right under the ESPP or (b) the date on which such purchase right is deemed exercised, whichever is lower.

As of June 30, 2017, an aggregate of 511,333 shares of common stock were reserved for issuance under the Company’s ESPP, of which 11,333 shares of common stock have been issued under the ESPP and 500,000 shares are available for future issuances.

As of June 30, 2017, we have not sold any shares of common stock to employees, directors, and consultants for cash consideration upon the exercise of stock options and stock awards.

Unless otherwise noted, all of the transactions described in Item 15 were exempt from registration under the Securities Act pursuant to Section 4(a)(2) of the Securities Act in that such sales did not involve a public offering, under Rule 701 promulgated under the Securities Act, in that they were offered and sold either pursuant to written compensatory plans or pursuant to a written contract relating to compensation, as provided by Rule 701, or under Rule 506 of Regulation D promulgated under the Securities Act.

ITEM 16. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES

See the Exhibit Index set forth on page II-6 to this Registration Statement, which is incorporated herein by reference.

ITEM 17. UNDERTAKINGS

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, or the Act, may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The Registrant hereby undertakes:

(a) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

provided, however, that paragraphs (a)(i), (a)(ii) and (a)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Exchange Act that are incorporated by reference in the registration statement.

(b) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(c) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;

(d) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the Registration Statement as of the date the filed prospectus was deemed part of and included in the Registration Statement; and

Table of Contents

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the Registration Statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the Registration Statement relating to the securities in the Registration Statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the Registration Statement or made in a document incorporated or deemed incorporated by reference into the Registration Statement or prospectus that is part of the Registration Statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the Registration Statement or prospectus that was part of the Registration Statement or made in any such document immediately prior to such effective date;

(e) That, for purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part of this Registration Statement as of the time it was declared effective;

(f) That, for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(g) To deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information; and

(h) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
