Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On March 26, 2015, we entered into an amendment to our existing Controlled Equity Offering^SM Sales Agreement with Cantor Fitzgerald & Co. (“Cantor”), pursuant to which we may issue and sell shares of common stock from time to time through Cantor acting as sales agent, having an aggregate offering price of up to $14,257,211, which is the balance remaining from the $18,000,000 originally contemplated by the sales agreement, after taking into account the $3,742,789 previously sold under the sales agreement. Sales of our common stock through Cantor, if any, may be made by any method deemed to be an “at-the-market” offering as defined in Rule 415 under the U.S. Securities Act of 1933, as amended, or any other method permitted by law, including in privately negotiated transactions. Subject to the terms and conditions of the sales agreement, Cantor will use commercially reasonable efforts consistent with its normal trading and sales practices, applicable state and federal law, rules and regulations and the rules of The NASDAQ Capital Market to sell shares from time to time based upon our instructions, including any price, time or size limits specified by us. We will pay Cantor a commission of 3.0% of the aggregate gross proceeds from each sale of shares and we have agreed to provide Cantor with customary indemnification and contribution rights.

The foregoing summary of such amendment does not purport to be complete and is qualified in its entirety by reference to the full text of such amendment, a copy of which is filed herewith as Exhibit 1.1. This Current Report on Form 8-K also incorporates by reference the amendment to the sales agreement into our shelf registration statement on Form S-3 (File No. 333-192606) previously filed with the SEC.

This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of an offer to buy any shares under such amendment, nor shall there be any sale of such shares in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.
