(the "Issuer"). Except as specifically provided herein, this Amendment No. 15 does not modify any of the information previously reported in the Schedule 13D, which remains unchanged.

Item 4.

Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and supplemented as follows: On February 27, 2026, 474,632 shares held by NSV Partners III, L.P. and 220,086 shares held by New Science Ventures, LLC, respectively, were distributed on a pro rata basis for no consideration. The Reporting Person is the majority member and managing member of (i) NSV Partners III GP, LLC, which is the general partner of NSV Partners III, L.P., and (ii) New Science Ventures, LLC. On March 4, 2026, pursuant to the Agreement and Plan of Merger, dated as of January 7, 2026 (the "Merger Agreement"), by and among the Issuer, Eli Lilly and Company, an Indiana corporation ("Parent"), and RYLS Merger Corporation, a Delaware corporation and wholly-owned subsidiary of Parent ("Merger Sub"), Merger Sub merged with and into the Issuer, with the Issuer surviving the Merger as a wholly owned subsidiary of Parent (the "Merger"). At the effective time of the Merger (the "Effective Time"), all of the shares of the Common Stock beneficially owned by the Reporting Person immediately prior to the Effective Time were converted into the right to receive $14.00 per share in cash, less any applicable tax withholding (the "Common Merger Consideration"), and all of the shares of Common Stock acquirable upon the exercise of stock options held by the Reporting Person immediately prior to the Effective Time were canceled and converted into the right to receive an amount in cash, without interest and less any applicable tax withholdings, equal to the product of (x) the total number of shares of Common Stock subject to such stock option immediately prior to the Effective Time multiplied by (y) the excess, if any, of the Common Merger Consideration over the applicable exercise price per share of Common Stock under such stock option. As a result of the Merger, as of the Effective Time, the Reporting Person no longer beneficially owned any securities of the Issuer, and the Voting and Support Agreement described in Item 4 of Amendment No. 14 to this Schedule 13D terminated in accordance with its terms.
