Explanatory Note
Pursuant to Rule 13d-2 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), this Amendment No. 2 to Schedule 13D (this “Amendment No. 2”) amends the Schedule 13D originally filed with the United States Securities and Exchange Commission (the “SEC”) on June 7, 2013, as amended by a Schedule 13D/A on February 10, 2014 (the “Schedule 13D”) by Bay City Capital LLC, a Delaware limited liability company (“BCC”), on behalf of the Reporting Persons pursuant to the Joint Filing Agreement attached to the Original Schedule 13D as Exhibit 99.1. Except as specifically amended by this Amendment No. 2, items in the Schedule 13D remain unchanged. Capitalized terms used but not otherwise defined herein have the meanings ascribed to them in the Schedule 13D. BCC is the manager of Bay City Capital Management V LLC, a Delaware limited liability company (“Management V”), which is the general partner of Bay City Capital Fund V, L.P., a Delaware limited partnership (“Fund V”), and Bay City Capital Fund V Co-Investment Fund, L.P., a Delaware limited partnership (“Co-Investment V”). BCC is also an advisor to Fund V and Co-Investment V.
| Item 5. | Interest in Securities of the Issuer. |
Items 5(a) and (b) of the Schedule 13D are amended and restated in their entirety to read as follows:

| (1) | Fund V and Co-Investment V constitute a “group” under Section 13(d) of the Exchange Act and consequently are deemed to have beneficial ownership of all shares held by members of the group. |
| (2) | This percentage is calculated based upon 33,608,532 shares of the Issuer’s common stock outstanding as of August 8, 2014 as computed in accordance with Rule 13d-3(d)(1)(i) promulgated under the Exchange Act. |
| (3) | Management V holds no shares of common stock directly. Management V is deemed to have beneficial ownership of common stock owned by Fund V and Co-Investment V due to its role as general partner of such funds. Investment and voting decisions by Management V are exercised by BCC as manager. |
| (4) | BCC holds no shares of common stock directly. Due to its role as manager of Management V, BCC is deemed to have beneficial ownership of common stock deemed to be beneficially owned by Management V. |
| (5) | Amounts in this column include 24,532 shares for Fund V and 467 shares for Co-Investment V underlying stock options issued to Carl Goldfischer, a director of the Issuer, Managing Director of BCC and a Member of Management V, in connection with his service as a director of the Issuer. Dr. Goldfischer shall have the right to exercise (a) the stock option with respect to 17,666 shares upon the earlier of (i) the expiration of Dr. Goldfischer’s initial term of office as a director of the Issuer, scheduled to occur on the 2015 meeting of the Issuer’s stockholders and (ii) June 30, 2015, and (b) the stock option with respect to 7,333 shares on July 23, 2015. Dr. Goldfischer has entered into an agreement with Fund V and Co-Investment V to immediately transfer any shares obtained via such stock options to Fund V and Co-Investment V upon exercise. |
The information required by Item 5 with respect to persons with whom voting or dispositive power is shared is set forth in Items 2 and 3 of the Original Schedule 13D.
