Item 3.

Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated to read as follows:

As of January 11, 2024, Matthew Perry ceased to be a partner at Partners. Mr. Perry continues to serve as a director of the Issuer.

Item 5.

Interest in Securities of the Issuer.

Items 5(a)-(c) are hereby amended and restated to read as follows:

(a)       The aggregate percentage of Shares reported owned by each person named herein is based on 11,487,808 Shares outstanding as of November 2, 2023, which is the total number of Shares outstanding as reported in the Issuer’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 7, 2023.

As of the date hereof, the Reporting Persons and the Partners Managed Accounts hold an aggregate of 5,003 shares of Series X Preferred Stock, convertible into an aggregate of 5,003,000 Shares. Each share of Series X Preferred Stock is convertible into 1,000 Shares.

As of the date hereof, the Series X Beneficial Ownership Limitation prohibits the conversion of all the Series X Preferred Stock held by the Reporting Persons and the Partners Managed Accounts.

As of the date hereof, (i) BVF beneficially owned 1,789,844 Shares, excluding 2,313,000 Shares issuable upon the conversion of certain Series X Preferred Stock held by it, representing percentage ownership of approximately 15.6% of the Shares outstanding, (ii) BVF2 beneficially owned 1,618,637 Shares, excluding 1,506,000 Shares issuable upon the conversion of certain Series X Preferred Stock held by it, representing percentage ownership of approximately 14.1% of the Shares outstanding, (iii) Trading Fund OS beneficially owned 75,287 Shares, excluding 412,000 Shares issuable upon the conversion of certain Series X Preferred Stock held by it, representing percentage ownership of less than 1% of the Shares outstanding, and (iv) 149,975 Shares were held in the Partners Managed Accounts, excluding 772,000 Shares issuable upon the conversion of certain Series X Preferred Stock held in the Partners Managed Accounts, representing percentage ownership of approximately 1.3% of the Shares outstanding.

BVF2 GP, as the general partner of BVF2, may be deemed to beneficially own the 1,618,637 Shares beneficially owned by BVF2, representing percentage ownership of approximately 14.1% of the Shares outstanding.

(c)       The Reporting Persons have not entered into any transactions in the securities of the Issuer during the past sixty days.

The filing of this Schedule 13D shall not be deemed an admission that the Reporting Persons are, for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, the beneficial owners of any securities of the Issuer that he or it does not directly own. Each of the Reporting Persons specifically disclaims beneficial ownership of the securities reported herein that he or it does not directly own.
