SCHEDULE 13D

This Amendment No. 1 (“Amendment No. 1”) amends and supplements the Schedule 13D originally filed with the Securities and Exchange Commission (the “SEC”) on May 22, 2015 by the Reporting Persons, (the “Schedule 13D”), with respect to shares of common stock, par value $0.001 per share, of the Issuer (“Common Stock”) beneficially owned by the Reporting Persons. This Amendment No. 1 is being filed to report that the Reporting Persons have ceased to be the beneficial owner of more than 5% of the class of securities. Except as amended or supplemented in this Amendment No. 1, all other information in the Schedule 13D is as set forth in the Schedule 13D. Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable. Capitalized terms used herein but not defined shall have the meanings ascribed thereto in the Schedule 13D.

The following Items of the Schedule 13D are hereby amended as follows:

Item 2. Identity and Background.

(a) This Amendment No. 1 is being filed on behalf of each of the following persons pursuant to Rule 13d-1(k) of Regulation D-G under the Securities Exchange Act of 1934, as amended (the “Exchange Act”): PVP V, PVPE V, PVPFF V, PVPSFF V, PVM V, Flint, McGuire and Nashat (collectively, the “Reporting Persons”). The Reporting Persons are making this single, joint filing because they may be deemed to constitute a “group” within the meaning of Section 13(d)(3) of the Exchange Act. The agreement between the Reporting Persons to file as a group (the “Joint Filing Agreement”) is attached hereto as Exhibit A.

(c) Flint and McGuire are the managing members of PVM V, and Amir Nashat (“Nashat”) is the holder of an assignee interest in PVM V.

The principal business address of each of the entities and individuals named in this Item 2 is c/o Polaris Partners, One Marina Park Drive, 10th Floor, Boston, MA 02210.

Item 5. Interest in Securities of the Issuer.

The information below is based on a total of 3,531,370 shares of Common Stock outstanding as of June 28, 2019 as reported by the Issuer to the Reporting Persons, after taking into account a 1:14 reverse stock split of the Issuer’s Common Stock effected on June 28, 2019.

(a) PVP V directly beneficially owns 125,992 shares of Common Stock, or approximately 3.6% of the Common Stock outstanding. PVPE V directly beneficially owns 2,456 shares of Common Stock, or approximately 0.1% of the Common Stock outstanding. PVPFF V directly beneficially owns 863 shares of Common Stock, or approximately 0.0% of the Common Stock outstanding. PVPSFF V directly beneficially owns 1,260 shares of Common Stock, or approximately 0.0% of the Common Stock outstanding. PVM V, as the general partner of PVP V, PVPE V, PVPFF V and PVPSFF V, may be deemed to indirectly beneficially own the securities owned by PVP V, PVPE V, PVPFF V and PVPSFF V. Nashat directly owns 898 shares of Common Stock, or approximately 0.0% of the Common Stock outstanding.

(b) The managing members of PVM V may be deemed to share the power to vote or direct the voting of and to dispose or direct the disposition of the securities of the Issuer that are beneficially owned by PVP V, PVPE V, PVPFF V and PVPSFF V. Each such person disclaims beneficial ownership of all securities other than those he or she owns directly, if any, or by virtue of his or her indirect pro rata interest, as a member of PVM V, in the securities owned by PVP V, PVPE V, PVPFF V and PVPSFF V. PVM V may be deemed to have sole power to vote or direct the voting of and to dispose or direct the disposition of the securities of the Issuer that are beneficially owned by PVP V, PVPE V, PVPFF V and PVPSFF V. Nashat, as a former member of the board of directors of the Issuer, is no longer deemed to share voting and dispositive power with respect to the securities of the Issuer beneficially owned by PVP V, PVPE V, PVPEF V and PVPSFF V, respectively.

(e) The Reporting Persons have ceased to be the beneficial owner of more than 5% of the class of securities due to dilution resulting from increases in the total number of shares of Common Stock outstanding.
