NOTES TO CONDENSED FINANCIAL STATEMENTS

(Unaudited)

 

 

1.

Nature of the Business

Proteostasis Therapeutics, Inc. (the “Company”) was incorporated in Delaware on December 13, 2006. The Company is an innovative biopharmaceutical company committed to the discovery and development of novel therapeutics that treat diseases caused by an imbalance in the proteostasis network, a set of pathways that control protein biosynthesis, folding, trafficking and clearance. The Company’s initial therapeutic focus is on cystic fibrosis, which is caused by defects in the cystic fibrosis transmembrane conductance regulator (“CFTR”) protein and insufficient CFTR protein function. The Company’s lead product candidate, PTI-428, is in early clinical development, and the Company’s other drug candidates are in the clinical, preclinical development and discovery phases.

The Company has incurred losses from operations since its inception. As of March 31, 2017, the Company had an accumulated deficit of $172.5 million. During the three months ended March 31, 2017, the Company incurred a loss of $15.1 million and used $15.3 million of cash in operations. The Company expects to continue to generate operating losses in the foreseeable future. The Company currently expects that its cash, cash equivalents and short-term investments of $70.2 million will be sufficient to fund its operating expenses and capital requirements, based upon its current operating plan, at least 12 months from the issuance date of these financial statements. The future viability of the Company beyond that point is dependent on its ability to raise additional capital to finance its operations. Although the Company has been successful in raising capital in the past, there is no assurance that it will be successful in obtaining such additional financing on terms acceptable to the Company, if at all. If the Company is unable to obtain funding, the Company would be forced to delay, reduce or eliminate its research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect its business prospects, or the Company may be unable to continue operations.

Summary of Significant Accounting Policies

Unaudited Interim Financial Information

The condensed balance sheet at December 31, 2016 was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (“GAAP”). The accompanying condensed financial statements as of March 31, 2017 and for the three months ended March 31, 2017 are unaudited. The accompanying unaudited interim financial statements have been prepared by the Company, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited condensed financial statements should be read in conjunction with the Company’s audited financial statements and the notes thereto for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 30, 2017. In the opinion of management, all adjustments, consisting only of normal recurring adjustments as necessary, for the fair statement of the Company’s condensed financial position as of March 31, 2017 and condensed results of its operations and cash flows for the three months ended March 31, 2017 have been made. The results of operations for three months ended March 31, 2017 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2017.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Significant estimates and assumptions reflected in these financial statements include, but are not limited to, revenue recognition, the accrual for research and development expenses and the valuation of common stock and the derivative liability. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates.

Restricted Cash

As of March 31, 2017 and December 31, 2016, restricted cash consisted of a certificate of deposit collateralizing a letter of credit issued as a security deposit in connection with the Company’s lease of its corporate facilities.

8


 

Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. As of March 31, 2017 and December 31, 2016, the Company’s cash equivalents consisted of money market funds.

Short-term Investments

Short-term investments represent holdings of available-for-sale marketable securities in accordance with the Company’s investment policy and cash management strategy. Short-term investments mature within one-year from the balance sheet date. Investments in marketable securities are recorded at fair value, with any unrealized gains and losses, net of taxes, reported as a component of stockholders’ equity until realized or until a determination is made that an other-than-temporary decline in market value has occurred. The cost of marketable securities sold is determined based on the specific identification method and any realized gains or losses on the sale of investments are reflected as a component of other expense, net.

Fair Value Measurements

Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

 

Level 1—Quoted prices in active markets for identical assets or liabilities.

 

Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.

 

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.

The Company’s derivative liability, short-term investments and cash equivalents are carried at fair value determined according to the fair value hierarchy described above (see Note 4). The carrying value of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate their fair value due to the short-term nature of these assets and liabilities.

Net Loss per Share

In February 2016, upon the closing of the IPO, all of the outstanding shares of the Company’s redeemable convertible preferred stock automatically converted into 9,699,600 shares of the Company’s common stock. Prior to this conversion, the Company followed the two-class method when computing net loss per share as the Company had issued shares that met the definition of participating securities. The two-class method determines net loss per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed. The Company’s redeemable convertible preferred stock contractually entitled the holders of such shares to participate in dividends, but did not contractually require the holders of such shares to participate in losses of the Company. Accordingly, the two-class method did not apply for periods in which the Company reported a net loss or a net loss attributable to common stockholders resulting from dividends or accretion related to its redeemable convertible preferred stock.

Basic net income (loss) per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net loss per share attributable to common stockholders is computed by dividing the diluted net loss attributable to common stockholders by the weighted average number of common shares, including potential dilutive common shares assuming the dilutive effect of outstanding stock options and unvested restricted common shares, as determined using the treasury stock method. For periods in which the Company has reported net losses, diluted net loss per common share attributable to common stockholders is the same as basic net loss per common share attributable to common stockholders, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. For any period in which the Company has reported net income, basic net income per common share attributable to common stockholders is adjusted for certain amounts to calculate diluted net loss per common share attributable to common stockholders, since

dilutive common shares are assumed to have been issued if their effect is dilutive and not to have been issued if their effect is anti-dilutive.

Recently Issued Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which supersedes existing revenue recognition guidance under GAAP. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard defines a five-step process to achieve this principle, and will require companies to use more judgment and make more estimates than under the current guidance. The Company expects that these judgments and estimates will include identifying performance obligations in the customer contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which delays the effective date of ASU 2014-09 such that the standard is effective for public entities for annual periods beginning after December 15, 2017 and for interim periods within those fiscal years. Early adoption of the standard is permitted for annual periods beginning after December 15, 2016. In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing. The new standard clarifies two aspects of ASU 2014-09, Revenue from Contracts with Customers (Topic 606): identifying performance obligations and the licensing implementation guidance. These new standards will become effective for the Company on January 1, 2018. The Company is currently evaluating the impact that the adoption of these new standards will have on its financial statements and related disclosures

In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). This guidance will require that lease arrangements longer than 12 months result in an entity recognizing an asset and liability equal to the present value of the lease payments in the statement of financial position. This guidance is effective for annual periods beginning after December 15, 2018, and interim periods therein. This standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of ASU 2016-02 will have on its financial statements and related disclosures.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). The new standard involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The new standard was adopted by the Company on January 1, 2017 on a modified retrospective basis. As a result, the Company has made an accounting policy election to account for forfeitures as they occur. The adoption of ASU 201609 also requires excess tax benefits and tax deficiencies be recorded in the income statement as opposed to additional paidin capital when the awards vest or are settled. This had no material impact on the condensed financial statements as of and for the three months ended March 31, 2017.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The new standard clarifies certain aspects of the statement of cash flows, including the classification of debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, distributions received from equity method investees and beneficial interests in securitization transactions. The new standard also clarifies that an entity should determine each separately identifiable source or use within the cash receipts and cash payments on the basis of the nature of the underlying cash flows. In situations in which cash receipts and payments have aspects of more than one class of cash flows and cannot be separated by source or use, the appropriate classification should depend on the activity that is likely to be the predominant source or use of cash flows for the item. The new standard will be effective for the Company on January 1, 2018. The Company is currently evaluating the impact that the adoption of this standard will have on its statements of cash flows.

Derivative Liability

The fair value of the derivative liability is based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The fair value of the derivative instrument was determined using the Monte-Carlo simulation analysis. In determining the fair value of the derivative liability, the inputs impacting fair value include the fair value of the Company’s common stock, expected term of the derivative instrument, expected volatility of the common stock price, risk-free interest rate, expected sales-based milestone payments, discount rate, probability of a change of control event, and the probability that the counterparty would elect to accept the alternative cash payment in lieu of its right to the future sales-based milestone payments.

 

As of March 31, 2017 and December 31, 2016, the Company determined the per share common stock price available based on the closing price of its common stock on the NASDAQ Global Market as of March 31, 2017. The Company determined the expected term of the instrument to be 2.50 years as of March 31, 2017 and December 31, 2016, respectively. The Company estimated its expected stock volatility to be 73.5% and 81.1% as of March 31, 2017 and December 31, 2016, respectively, based on the historical volatility of publicly traded peer companies for terms matching the expected term of the instrument for each respective period. The risk-free interest rate was determined to be 1.39% and 1.33% as of March 31, 2017 and December 31, 2016, respectively, by reference to the U.S. Treasury yield curve for terms matching the expected term of the instrument for each respective period.

Stock-Based Compensation

2016 Stock Option and Incentive Plan

On February 3, 2016, the Company’s stockholders approved the 2016 Stock Option and Incentive Plan (the “2016 Plan”), which became effective on February 9, 2016. The 2016 Plan provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock units, restricted stock awards and other stock-based awards. The number of shares initially reserved for issuance under the 2016 Plan is 1,581,839 shares. The number of shares of common stock that may be issued under the 2016 Plan will automatically increase on each January 1, beginning on January 1, 2017, by the lesser of 3% of the shares of the

12


 

Company’s common stock outstanding on the immediately preceding December 31 or an amount determined by the Company’s board of directors or the compensation committee of the board of directors. The shares of common stock underlying any awards that are forfeited, canceled, repurchased or are otherwise terminated by the Company under the 2016 Plan and the 2008 Plan will be added back to the shares of common stock available for issuance under the 2016 Plan.

As of March 31, 2017, the total number of shares reserved under the 2016 Plan and 2008 Plan was 3,655,783 and the Company had 1,569,330 shares available for future issuance under the 2016 Plan.

2016 Employee Stock Purchase Plan

On February 3, 2016, the Company’s stockholders approved the 2016 Employee Stock Purchase Plan (the “2016 ESPP”), which became effective in connection with the completion of the Company’s initial public offering. A total of 138,757 shares of common stock were reserved for issuance under this plan. In addition, the number of shares of common stock that may be issued under the 2016 ESPP will automatically increase on each January 1, beginning on January 1, 2017 and ending on January 1, 2026, by the least of (i) 138,757 shares of common stock, (ii) 1% of the Company’s shares of common stock outstanding on the immediately preceding December 31 and (iii) an amount determined by the Company’s board of directors or the compensation committee of the board of directors.

As of March 31, 2017, the total number of shares reserved under the 2016 ESPP was 277,514 shares. During the three months ended March 31, 2017 and 2016, no shares were issued under the 2016 ESPP.

Stock Option Grants and Shares to Non-employees

Prior to 2013, the Company issued options to purchase 203,964 shares of common stock to non-employees, primarily members of the Company’s scientific advisory board, that vest upon the achievement of specified development and clinical milestones. As of March 31, 2017, options for the purchase of 83,250 shares held by non-employees remained unvested, pending achievement of the specified milestones, and had an aggregate fair value of $0.5 million.

Collaboration Agreement

Astellas

Under the Collaborative Research, Development, Commercialization and License Agreement (as further amended, the “Astellas Agreement”) with Astellas Pharma Inc. (“Astellas”), entered into in November 2014, the Company recognized revenue of $1.0 million and $0.4 million for the three months ended March 31, 2017 and 2016, respectively. The Company recognizes revenue from all upfront payments, research funding payments, non-substantive milestone payments and reimbursements of third-party costs under this arrangement, together as a single unit, over the three and a half year research term of the agreement, which commenced in January 2015, with a cumulative catch-up for the elapsed portion of the services being recognized at the time any non-substantive milestone payment or other consideration is earned. Amounts recorded as deferred revenue under the Astellas Agreement totaled $2.6 million and $3.0 million as of March 31, 2017 and December 31, 2016, respectively.

Biogen

Under the now-terminated collaboration agreement we had with Biogen New Ventures, formerly Biogen Idec New Ventures Inc. (“Biogen”), we recognized revenue of $0.8 million for the three months ended March 31, 2016. The Company did not have any deferred revenue under the Biogen agreement as of March 31, 2017 and December 31, 2016 and will not recognize any additional revenue under this terminated agreement in the future.

The Company’s potential dilutive securities, which include stock options and a warrant to purchase common stock, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same.

The Company has reported a net loss for all periods presented. Therefore, diluted net loss per common share is the same as basic net loss per common share. The following potentially dilutive securities outstanding, prior to the use of the treasury stock method or if-converted method, have been excluded from the computation of diluted weighted-average shares outstanding, because such securities had an antidilutive impact due to the losses reported:

Management’s Discussion and Analysis of Financial Condition and Results of Operation

The following discussion and analysis of our financial condition and the results of operations should be read in conjunction with our financial statements and related notes thereto included elsewhere in this Quarterly Report on Form 10-Q (“Quarterly Report”) and our audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016 (the “Annual Report”) filed with the Securities and Exchange Commission on March 30, 2017. Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report, including information with respect to our plans and strategy for our business, includes forward looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section in our Annual Report and in this Quarterly Report, our actual results could differ materially from the results described, in or implied, by the forward-looking statements contained in the following discussion and analysis.

Overview

We are an innovative biopharmaceutical company committed to the discovery and development of novel therapeutics that treat diseases caused by an imbalance in the proteostasis network, a set of pathways that control protein biosynthesis, folding, trafficking and clearance. Leveraging our unique and comprehensive expertise of the proteostasis network, we have developed the Disease Relevant Translation, or DRT, technology platform, a validated drug screening approach for identifying highly translatable therapeutics based on predictive and functionally pertinent phenotypic assays and disease relevant models. Using this proprietary platform, we identified a new class of small molecules, which we call amplifiers, that modulate proteins in the proteostasis network. Our initial therapeutic focus is cystic fibrosis, or CF, which is caused by defects in the cystic fibrosis transmembrane conductance regulator, or CFTR, protein and insufficient CFTR protein function. We continue to grow our CF focused pipeline with novel CFTR modulators including correctors, potentiators, read-through agents and amplifiers. We have exploited the novel mechanism of action of the amplifiers as a drug screening tool in our DRT platform and have identified correctors and potentiators to be developed as part of a combination therapy. We are developing and, if approved, intend to commercialize our own triple combination therapy to be indicated for CF patients who have at least one F508del mutation representing the majority of the patient population.

The approval of CFTR modulator based therapy, consisting of a potentiator and a combination of a potentiator and a corrector, has validated the clinical benefit of a small molecule pharmacological approach to improve CFTR function and has become a standard of care for eligible CF patients. These developments have spurred drug discovery and development initiatives that include a combinational approach of multiple modulators. Several companies are currently developing combined uses of three CFTR modulators whose goal is the restoration of CFTR protein activity in CF patients by using one potentiator and two corrector molecules. Correctors, such as lumacaftor or tezacaftor, are believed to improve protein folding and trafficking to enable abnormally folded CFTR protein to achieve some level of activity without repairing the actual protein mutation. Potentiators, such as ivacaftor, are believed to increase the opening time of the CFTR protein channel resulting in higher ion flow across the cell membrane.

Unlike other triple combination drug discovery and development approaches for CF, our program includes PTI-428, an amplifier, a novel CFTR modulator with unique and distinguished molecular properties. PTI-428 is an orally bioavailable CFTR modulator belonging to the amplifier class. CFTR modulators are compounds that affect the folding, trafficking, function and clearance of CFTR protein and can be classified according to the ways in which they affect CFTR protein. Amplifiers, which include PTI-428, are CFTR modulators that selectively increase the amount of the unfolded form of CFTR protein, thereby providing additional substrate for other CFTR modulators, such as correctors and potentiators, to act upon. Using industry-standard in vitro studies, we have demonstrated that co-administration of PTI-428 with these other CFTR modulators significantly improves the in vitro CFTR protein activity achieved by these CFTR modulators alone.

Due to the unique ability of amplifiers to selectively increase the amount of the unfolded form of CFTR protein and its synergistic mechanism of action with certain other types of CFTR modulators, we believe that PTI-428 could become the anchor therapeutic agent for combination therapies comprising multiple classes of CFTR modulators for the treatment of CF. A triple combination regimen that includes PTI-428 with PTI-801, a corrector, and PTI-808, a potentiator, has been shown to restore in vitro CFTR protein activity to approximately 100% of normal, in patient-derived human bronchial epithelial, or HBE, cells homozygous for F508del.

With the recent advent of CFTR modulators, the CF treatment paradigm is shifting from palliative care, which addresses only the symptoms of CF, to disease-modifying agents that target the genetic mutations and protein dysfunction that cause the disease. We are developing and intend to commercialize PTI-428 for CF patients with an F508del mutation of the CFTR gene, the most common CFTR gene mutation. In the United States, approximately 86% of all CF patients have an F508del mutation of the CFTR gene, of which approximately 53% are homozygous (having two copies of the F508del mutation), and approximately 47% are heterozygous (having an F508del mutation and one other mutation).

Our analyses of published data by Vertex Pharmaceuticals Incorporated, or Vertex, of its CFTR modulators (the potentiator ivacaftor and the correctors lumacaftor and tezacaftor) and combinations thereof, show a strong correlation between the in vitro CFTR protein activity and lung function improvement. We have shown in vitro that PTI-428 increases the amount of available CFTR protein and, when combined with ivacaftor and either lumacaftor or tezacaftor, nearly doubles the CFTR protein activity in the cell compared to a combination of only ivacaftor and either lumacaftor or tezacaftor. In December 2015, the investigational new drug application, or IND, that we submitted to the U.S. Food and Drug Administration, or FDA, for a Phase 1 clinical trial to evaluate our PTI-428 product candidate became effective. We initiated our first Phase 1 clinical trial in CF patients and healthy volunteers in the first half of 2016. The Phase 1 trial in CF patients includes single ascending dose, or SAD, and multiple ascending dose, or MAD, cohorts. The Phase 1 trial in healthy volunteers includes SAD and MAD cohorts to assess the safety, pharmacokinetic and exploratory biomarker results

We reported preliminary safety, pharmacokinetic and exploratory biomarker data from SAD and MAD cohorts in the Phase 1 clinical trial in healthy volunteers. The safety review committee, which includes both our representatives and those of the clinical contract research organization that we have retained to conduct our trials, did not identify any safety concerns about PTI-428 based upon reviews of adverse events, vital signs, ECGs, chemistry and hematology lab values from healthy volunteers in these cohorts. Preliminary exploratory biomarker nasal CFTR mRNA and protein data confirm target engagement. Additionally, we observed approximately a two-fold increase in CFTR mRNA and protein from nasal brushing data in healthy volunteer subjects where PTI-428 achieved a threshold concentration further confirming the biological activity of the drug in target tissue. We aim to report preliminary data, including lung function, from a 14-day MAD cohort from at least 8 CF patient subjects receiving PTI-428 or placebo for 7 days in addition to Orkambi as their background, standard of care therapy in the second quarter of 2017. We will assess lung function, as measured by forced expiratory volume in one second, or FEV1, as well as changes in sweat chloride. Upon completion of the Phase 1 clinical trial, we plan to initiate a 28-day Phase 2 clinical trial for PTI-428, and expect data from patients stable on Orkambi in the second half of 2017. We expect patients from the 14-day MAD cohort to be eligible to enroll in this longer duration study after a wash-out period. The goal of these cohorts is to identify a dose level for the triple combination proof of concept, or POC, study described in greater detail below. We plan to conduct studies in patients on Kalydeco or in those patients who are not taking CFTR modulator therapy. We intend to expand our clinical trial for PTI-428 in Europe where we expect to devote substantial resources having received approval and favorable ranking from the Clinical Trial Network of the European Cystic Fibrosis Society, or the CTN, a patient advocacy group that reviews protocols for CF trials and provides recommendations to its member sites. Discussions with the Therapeutic Development Network, or TDN, part of the Cystic Fibrosis Foundation Therapeutics, the U.S. equivalent to the CTN, continue for the sanctioning of our PTI-428 study, however we cannot assure you the TDN will ever approve this study, or, if approved, the timing of such approval. We believe TDN endorsement is an important factor for U.S. CF centers in deciding whether to participate in a CF trial, and which trials to prioritize. TDN has deferred endorsement of PTI-428, which we believe has contributed to a delay in our trial. There is also a large number of CF programs in clinical development at this time, including numerous corrector and combination trials from Vertex and other companies with greater resources and experience than us, which we believe has also contributed to a delay in our PTI-428 trial.

We are leveraging our DRT technology platform and other expertise to design and develop our own correctors and potentiators that are optimized to work synergistically with our drug candidates and show a higher combined effect compared to combinations with third-party CFTR modulators. We believe the mechanism of action of PTI-428 enhances the yield of high throughput screening, or HTS, of small molecule libraries and has enabled the identification of a number of novel proprietary correctors and potentiators that restored in vitro CFTR protein activity to normal levels in HBE cells homozygous for F508del. We have submitted an IND for PTI-801, a corrector molecule, to the FDA in the first quarter of 2017, which is now active, and plan to submit the IND for PTI-808, a potentiator molecule, during the second quarter of 2017 subject to satisfactory completion of our toxicology and other preclinical testing to support our IND application. PTI-801 and PTI-808 are drug development candidates which, when combined with PTI-428, are active components of our PTI-NC-733 triple combination product candidate. We expect POC data in CF patients treated with PTI-801 in the second half of 2017 and intend to initiate dose range finding, or DRF, studies with PTI-808 at the end of 2017. The DRF study with PTI-808 is also intended to be considered a POC study for the triple combination. We believe that the treatment paradigm in CF for the vast majority of patients could be based on combination therapies of CFTR modulators anchored by PTI-428. Our internal drug discovery effort is ongoing, and our DRT technology platform has and continues to generate additional CFTR modulators of known and new pharmacological classes, including readthrough agents, that are being evaluated for further development.

A Phase 1 healthy volunteer study for PTI-801 to assess its safety and PK has commenced. The Phase 1 study will also investigate PTI-801 in CF patients. We plan for this trial to run in U.S. and European sites and are working with both the TDN and CTN to review our protocol for sanctioning. Subject to favorable results from our healthy volunteer arm, we expect data from patients stable on Orkambi who have been dosed with PTI-801 for 14 days in the second half of 2017. Subject to filing and effectiveness of an IND for PTI-808, and positive results from our PTI-428 and PTI-801 programs, we aim to initiate a trial for our triple combination by the end of 2017 in CF patients homozygous for F508del who are not taking Orkambi, focusing on countries where Orkambi is not widely reimbursed or available, among others.

In addition, we have partnered with a major pharmaceutical company, Astellas Pharma Inc., or Astellas, on our unfolded protein response, or UPR, program. The UPR program is intended to reduce the accumulation of unfolded proteins in the endoplasmic reticulum, or ER, which is observed in many diseases caused by an imbalance in the proteostasis network and characterized by defects in protein folding, trafficking and clearance, including genetic, neurodegenerative and retinal degenerative diseases. In August 2016, we announced the achievement of a preclinical milestone by demonstrating that selective modulation of the UPR pathway is an effective disease-modifying approach in the treatment of multiple diseases with few or no therapies currently available.

Since our inception in 2006, we have devoted substantially all of our resources to organizing and staffing our company, business planning, raising capital, acquiring and developing product and technology rights, and conducting research and development activities for our product candidates. We do not have any products approved for sale and have not generated any revenue from product sales. We have funded our operations to date with proceeds from the sale of preferred stock, the issuance of convertible promissory notes, proceeds from our initial public offering in February 2016, our follow-on public offering in September 2016, and, to a lesser extent, payments received in connection with collaboration agreements and a research grant.

Since our inception, we have incurred significant operating losses. Our net losses were $15.1 million and $8.0 million for the three months ended March 31, 2017 and 2016, respectively. As of March 31, 2017, we had an accumulated deficit of $172.5 million. We expect to continue to incur significant expenses and increasing operating losses for at least the next several years. We expect our expenses and capital requirements will increase substantially in connection with our ongoing activities, as we:

 

expand clinical trials for PTI-428;

 

advance our combination therapy candidates, PTI-801 and PTI-808, components of PTI-NC-733, into Phase 1 and Phase 2 clinical trials;

 

seek regulatory approval for our product candidates;

 

seek support and approval from our collaboration partners, the Therapeutics Development Network of the Cystic Fibrosis Foundation and other interested parties;

 

hire personnel to support our product development, manufacturing, commercialization and administrative efforts; and

 

advance the research and development efforts of our DRT technology platform and other product candidates, including, without limitation, back-up compounds.

We will not generate revenue from product sales unless and until we successfully complete clinical development and obtain regulatory approval for our product candidates. If we obtain regulatory approval for any of our product candidates, we expect to incur significant expenses related to developing our internal commercialization capability to support product sales, marketing and distribution. In addition, we will continue to incur additional costs associated with operating as a public company.

As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through the sale of public or private equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all. If we fail to raise capital or enter into such agreements as, and when, needed, we may have to significantly delay, scale back or discontinue the development and commercialization of one or more of our product candidates.

We expect that our cash, cash equivalents and short-term investments as of March 31, 2017 will enable us to fund our operating expenses and capital requirements, based upon our current operating plan, through the second quarter of 2018. See “—Liquidity and Capital Resources”.

Components of our Results of Operations

Revenue

To date, we have not generated any revenue from product sales and do not expect to generate any revenue from the sale of products in the foreseeable future. All of our revenue during the three months ended March 31, 2017 was derived from our collaboration agreement with Astellas, while all of our revenue during the three months ended March 31, 2016 was derived from our collaboration agreements with Astellas and Biogen.

Under the Astellas collaboration agreement, entered into in November 2014, we recognized revenue of $1.0 million and $0.4 million for the three months ended March 31, 2017 and 2016, respectively. We recognize revenue from all upfront payments, research funding payments, non-substantive milestone payments and reimbursements of third-party costs under this arrangement, together

17


 

as a single unit, over the three and a half-year research term, which commenced in January 2015, with a cumulative catch-up for the elapsed portion of the research services being recognized at the time any non-substantive milestone payment or other consideration is earned. Amounts recorded as deferred revenue under the Astellas collaboration agreement totaled $2.6 million and $3.0 million as of March 31, 2017 and December 31, 2016, respectively.

Under the now-terminated collaboration agreement we had with Biogen New Ventures, formerly Biogen Idec New Ventures Inc. (“Biogen”), we recognized revenue of $0.8 million for the three months ended March 31, 2016. We recognized revenue from all upfront license payments, research funding payments, non-substantive milestone payments and reimbursements of third-party costs under this arrangement, together as a single unit, over the four-year research term, which commenced in December 2013, with a cumulative catch-up for the elapsed portion of the research services being recognized at the time any non-substantive milestone payment or other consideration is earned. We did not have any deferred revenue under the agreement as of March 31, 2017 and December 31, 2016 and we will not recognize any additional revenue under this terminated agreement in the future.

We expect that any future revenue recognized under the Astellas collaboration agreement will fluctuate from quarter to quarter as a result of the uncertain timing of future milestone payments and the uncertain quantity of our research services provided from quarter to quarter. Further, subject to the terms and conditions of our collaboration agreement, our collaborator has certain unilateral rights to discontinue their participation in the research activities and, as a result, future payments to us under the agreement.

Operating Expenses

Research and Development Expenses

Research and development expenses, which include costs of research services incurred in connection with our collaboration agreements and research grant, consist primarily of costs incurred in connection with the discovery and development of our product candidates, which include:

 

employee-related expenses, including salaries, related benefits, travel and stock-based compensation expense for employees engaged in research and development functions;

 

expenses incurred in connection with the preclinical and clinical development of our product candidates and under agreements with contract research organizations, or CROs;

 

facilities, depreciation and other expenses, which include direct and allocated expenses for rent and maintenance of facilities, insurance and supplies; and

 

payments made under third-party licensing agreements.

We expense research and development costs as incurred. We recognize external development costs based on an evaluation of the progress to completion of specific tasks using information provided to us by our service providers.

Our direct research and development expenses are tracked on a program-by-program basis and consist primarily of external costs, such as fees paid to consultants, central laboratories, contractors and CROs in connection with our clinical trials and preclinical development activities. We do not allocate employee costs, costs associated with our platform technology and facility expenses, including depreciation or other indirect costs, to specific product development programs because these costs are deployed across multiple product development programs and, as such, are not separately classified. We use internal resources to manage our preclinical development activities and perform data analysis for such activities. These employees work across multiple development programs and, therefore, we do not track their costs by program.

The table below summarizes our research and development expenses incurred by development program:

We expect that our expenses will increase substantially in connection with our ongoing preclinical development activities and our clinical trials. At this time, we cannot reasonably estimate the costs for completing the clinical development of PTI-428 or PTI-801 for the treatment of CF or the cost associated with the development of any of our other product candidates.

18


 

The successful development and commercialization of our product candidates is highly uncertain. This is due to the numerous risks and uncertainties associated with product development and commercialization, including the uncertainty of:

 

the scope, progress, outcome and costs of our preclinical development activities, clinical trials and other research and development activities;

 

establishing an appropriate safety profile with IND-enabling studies;

 

successful patient enrollment in, and the initiation and completion of, clinical trials;

 

the cooperation and approval we receive from third parties including clinical investigators, CROs, the TDN and CTN;

 

the timing, receipt and terms of any marketing approvals from applicable regulatory authorities;

 

establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;

 

obtaining, maintaining, defending and enforcing patent claims and other intellectual property rights;

 

significant and changing government regulation;

 

launching commercial sales of our product candidates, if and when approved, whether alone or in collaboration with others; and

 

maintaining a continued acceptable safety profile of the product candidates following approval.

Any changes in the outcome of any of these variables, or others identified within this filing, with respect to the development of our product candidates in preclinical and clinical development could mean a significant change in the costs and timing associated with the development of these product candidates. For example, if the FDA or another regulatory authority were to delay our planned start of clinical trials or require us to conduct clinical trials or other testing beyond those that we currently expect or if we experience significant delays in enrollment in any of our planned clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development of that product candidate.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related costs, including stock-based compensation, for personnel in executive, finance and administrative functions. General and administrative expenses also include direct and allocated facility-related costs as well as professional fees for legal, patent, consulting, accounting and audit services.

We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support our continued research activities and development of our product candidates. We also anticipate that we will continue to incur increased accounting, audit, legal, patent, regulatory, compliance, director and officer insurance costs and director expenses, as well as investor and public relations expenses associated with being a public company.

Other Income (Expense), Net

Interest Income. Interest income consists of interest earned on cash equivalents and short-term investments held by us during the three months ended March 31, 2017. There were no short-term investments held by us during the three months ended March 31, 2016.

Other Income (Expense), Net. Other income (expense), net primarily consists of the amortization of premium on our short-term investments and the gains or losses associated with the changes in the fair values of our derivative liability. The derivative liability relates to a cash settlement option associated with the change of control provision in our CFFT collaboration agreement, which meets the definition of a derivative. Therefore, we have classified this derivative as a liability that we remeasure to fair value at each reporting period, and we record the changes in the derivative liability as a component of other income (expense), net.

Critical Accounting Policies and Significant Judgments and Estimates

Our financial statements are prepared in accordance with generally accepted accounting principles in the United States, or GAAP. The preparation of our financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and the disclosure of contingent assets and liabilities in our financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis.

19


 

Our actual results may differ from these estimates under different assumptions or conditions. During the three months ended March 31, 2017, there were no material changes to our critical accounting policies. Our critical accounting policies are described under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations— Critical Accounting Policies and Significant Judgments and Estimates” in our Annual Report on Form 10-K filed with the Securities and Exchange Commission, or SEC, on March 30, 2017 and the notes to the financial statements appearing elsewhere in this Quarterly Report on Form 10-Q. We believe that of our critical accounting policies, the following accounting policies involve the most judgment and complexity:

 

revenue recognition;

 

accrued research and development expenses;

 

stock-based compensation; and

 

valuation of derivative liability.

Accordingly, we believe the policies set forth above are critical to fully understanding and evaluating our financial condition and results of operations. If actual results or events differ materially from the estimates, judgments and assumptions used by us in applying these policies, our reported financial condition and results of operations could be materially affected.

Revenue

Revenue was $1.0 million for the three months ended March 31, 2017, compared to $1.2 million for the three months ended March 31, 2016. The decrease of $0.2 million is the result of a reduction of $0.8 million of revenue recognized under the Biogen collaboration that terminated in the fourth quarter of 2016. This decrease was offset by an increase of $0.6 million of revenue recognized under the Astellas agreement which was largely driven by the timing of invoicing for reimbursable activity for the three months ended March 31, 2017. We did not receive any payment or reimbursement under the Astellas agreement during the three months ended March 31, 2016 as a result of the fourth amendment to such agreement.

Research and Development Expenses

Research and development expenses were $13.1 million for the three months ended March 31, 2017, compared to $6.9 million for the three months ended March 31, 2016. The increase of $6.2 million was primarily due to an increase of $3.1 million related to activities supporting the continued advancement of our Phase 1 clinical trials of PTI-428 and preclinical activities and early clinical trial costs supporting the advancement of PTI-801, PTI-808 and our combination solution, PTI-NC-733. Consulting fees associated with our preclinical activities and clinical trials increased by $0.9 million during the three months ended March 31, 2017 as compared to the three months ended March 31, 2016. Additionally, there was an increase of $1.4 million in personnel-related costs, including $0.2 million in employee stock-based compensation expense, primarily driven by an overall increase in headcount to support the development of our internal pipeline.

20


 

General and Administrative Expenses

General and administrative expenses were $3.2 million for the three months ended March 31, 2017, compared to $2.3 million for the three months ended March 31, 2016. The increase of $0.9 million in general and administrative expenses was primarily due to an increase of $0.6 million in personnel-related costs, including an increase of $0.3 million in non-employee stock-based compensation expense, primarily due to the effects of hiring additional full-time employees to support operations. Additionally, there was an increase of $0.4 million in professional fees, which is primarily the result of increased expenses related to consulting services provided during the three months ended March 31, 2017 to support our operating as a public company. These increases were offset by a decrease of $0.1 million in facility related costs.

Interest Income

We recorded interest income for the three months ended March 31, 2017 of $0.2 million as compared to no interest income for the three months ended March 31, 2016. The increase was primarily due to interest earned on short-term investments held during the three months ended March 31, 2017. There were no short-term investments outstanding during the three months ended March 31, 2016.

Other Income (Expense), Net

We recorded less than $0.1 million of other expense for the three months ended March 31, 2017 compared to less than $0.1 million of other income for the three months ended March 31, 2016.

Liquidity and Capital Resources

Since our inception, we have incurred significant operating losses. We have generated limited revenue to date from our collaboration agreements and research grant. We have not yet commercialized any of our product candidates, which are in various phases of preclinical development and clinical trials, and we do not expect to generate revenue from sales of any product for several years, if at all. We have funded our operations to date with proceeds received from our initial public offering and subsequent follow-on offering, the sale of preferred stock, the issuance of convertible promissory notes and, to a lesser extent, payments received in connection with collaboration agreements and a research grant.

As of March 31, 2017, we had cash, cash equivalents and short-term investments of $70.2 million. We expect that our cash, cash equivalents and short-term investments as of March 31, 2017 will enable us to fund our operating expenses and capital requirements, based upon our current operating plan, through the second quarter of 2018. Our future viability beyond that point is dependent on our ability to raise additional capital to finance our operations. Although we have been successful in raising capital in the past, there is no assurance that we will be able successful in obtaining such additional financing on terms acceptable to us, if at all. If we are unable to obtain funding, we could be forced to delay, reduce or eliminate our research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect our business prospects, or we may be unable to continue operations.

Operating Activities. Net cash used in operating activities was $15.3 million during the three months ended March 31, 2017, primarily driven by our net loss of $15.1 million and changes in our operating assets and liabilities of $0.9 million, partially offset by non-cash charges of $0.7 million. Our net loss was primarily attributed to an increase of $6.2 million in research and development activities associated with the advancement of our preclinical studies and clinical trials and an increase of $0.9 million in general and administrative expenses. 

 

During the three months ended March 31, 2016, operating activities used $8.4 million of cash, primarily resulting from our net loss of $8.0 million and cash used by changes in our operating assets and liabilities of $0.7 million, partially offset by net non-cash

21


 

charges of $0.3 million. Our net loss was primarily attributed to research and development activities and our general and administrative expenses, as we had limited collaboration revenue in the period.

Investing Activities. During the three months ended March 31, 2017, net cash provided by investing activities was $12.1 million, primarily consisting of proceeds received from maturities of short-term investments and offset by additional purchases of short-term investments.

During the three months ended March 31, 2016, we used less than $0.1 million of cash in investing activities, consisting of purchases of property and equipment.

Financing Activities. During the three months ended March 31, 2017, net cash provided by financing activities was less than $0.1 million, primarily resulting from the exercise of stock options.

During the three months ended March 31, 2016, net cash provided by financing activities was $44.4 million, primarily resulting from gross proceeds of $46.5 million from the sale of common stock in connection with the initial public offering, partially offset by payments of $2.1 million of initial public offering costs.

Operating Capital Requirements

We expect our expenses to increase substantially in connection with our ongoing activities, particularly as we advance the preclinical activities and clinical trials of our product candidates in development.

Our expenses will also increase as we:

 

pursue the clinical development of our most advanced product candidates, including PTI-428 and PTI-801;

 

seek the support and approval from our collaboration partners, the TDN and other interested parties;

 

continue the research and development of our other product candidates;

 

seek to identify and develop additional product candidates;

 

seek marketing approvals for any of our product candidates that successfully complete clinical development;

 

develop and expand our sales, marketing and distribution capabilities for our product candidates for which we obtain marketing approval;

 

scale up our manufacturing processes and capabilities to support our ongoing preclinical activities and clinical trials of our product candidates and commercialization of any of our product candidates for which we obtain marketing approval;

 

maintain, expand and protect our intellectual property portfolio;

 

expand our operational, financial and management systems and increase personnel, including personnel to support our clinical development, manufacturing and commercialization efforts and our operations as a public company; and

 

increase our product liability and clinical trial insurance coverage as we initiate our clinical trials and commercialization efforts.

Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical drugs, we are unable to estimate the exact amount of our working capital requirements. Our future funding requirements will depend on many factors, including:

 

the number and characteristics of the product candidates we pursue;

 

the scope, progress, results and costs of researching and developing our product candidates, and conducting preclinical studies and clinical trials;

 

the timing of, and the costs involved in, obtaining regulatory approvals for our product candidates;

 

the timing of, and costs involved in, manufacturing our drug candidates and any drugs we successfully commercialize;

 

our ability to establish and maintain strategic collaborations, licensing or other arrangements and the financial terms of such agreements;

 

delays that may be caused by changing regulatory requirements;

22


 

 

cost and timing of hiring new employees to support our continued growth;

 

the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims, including litigation costs and the outcome of such litigation; and

 

the timing, receipt and amount of sales of, or milestone payments related to or royalties on, our current or future product candidates, if any.

Until such time, if ever, as we can generate product revenue sufficient to achieve profitability, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaboration agreements, other third-party funding, strategic alliances, licensing arrangements or marketing and distribution arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of a common stockholder. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through other third-party funding, collaborations agreements, strategic alliances, licensing arrangements or marketing and distribution arrangements, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market products or product candidates that we would otherwise prefer to develop and market ourselves.

Based upon our current operating plan, we believe our existing cash, cash equivalents and short-term investments will enable us to fund our operating expenses and capital expenditure requirements through the second quarter of 2018.

The quarterly retainer may be settled in cash, common stock of the Company or a combination thereof, at our discretion.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined in the rules and regulations of the Securities and Exchange Commission.

 

 

Item  3.

Quantitative and Qualitative Disclosures About Market Risks

Interest Rate Fluctuation Risk

Our cash, cash equivalents and short-term investments as of March 31, 2017, consisted of money market funds, government-sponsored enterprise securities and U.S. treasury securities. The primary objectives of our investment activities are to preserve principal, provide liquidity and maximize income without significantly increasing risk. Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. However, because of the nature of the instruments in our portfolio, a sudden change in market interest rates would not be expected to have a material impact on our financial condition and/or results of operation.

Item  4.

Management’s Evaluation of our Disclosure Controls and Procedures.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities and Exchange Act of 1934 is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to our management, including our President and Chief Executive Officer, who is our principal executive officer, and our Vice President of Finance, who is also our principal financial and accounting officer, as appropriate, to allow timely decisions regarding required disclosure.

As of March 31, 2017, our management, with the participation of our principal executive officer and principal financial and accounting officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of 1934). Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our principal executive officer and principal financial and accounting officer have concluded based upon the evaluation described above that, as of March 31, 2017, our disclosure controls and procedures were effective at the reasonable assurance level.

There were no changes in our internal control over financial reporting during the three months ended March 31, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

 

 

Item  1.

Legal Proceedings

In the ordinary course of business, we are from time to time involved in lawsuits, claims, investigations, proceedings, and threats of litigation relating to intellectual property, commercial arrangements, employment and other matters. While the outcome of these proceedings and claims cannot be predicted with certainty, as of March 31, 2017, we were not party to any material pending legal proceedings, and we are not aware of any claims or actions pending or threatened against us that would have a material adverse impact on our financial position, results of operations or cash flows.

 

 

Item  1A.

Risk Factors

Information regarding risk factors appears in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2016, which was filed with the SEC on March 30, 2017. There have been no material changes from the risk factors previously disclosed in that Annual Report on Form 10-K.

 

Item  2.

Unregistered Sales of Equity Securities and Use of Proceeds

Use of Proceeds from Registered Securities

On February 17, 2016, we closed the sale of 6,250,000 shares of common stock to the public at an initial public offering price of $8.00 per share. The offer and sale of the shares in the IPO were registered under the Securities Act pursuant to a registration statement on Form S-1 (File No. 333-208735), which was filed with the SEC on December 23, 2015 and amended subsequently and declared effective on February 10, 2016. The underwriters of the offering were Leerink Partners and RBC Capital Markets, acting as joint book-running managers for the offering and as representatives of the underwriters. Baird and H.C. Wainwright & Co. acted as co-managers for the offering. We raised approximately $42.5 million in net proceeds in the IPO after deducting underwriting discounts and commissions of approximately $3.5 million and other offering expenses of $4.0 million. No offering expenses were paid directly or indirectly to any of our directors or officers (or their associates) or persons owning ten percent or more of any class of our equity securities or to any other affiliates. There has been no material change in the planned use of proceeds from our initial public offering as described in our final prospectus filed with the SEC pursuant to Rule 424(b) of the Securities Act.
