The following constitutes Amendment No. 3 ("Amendment No. 3") to the Schedule 13D filed with the Securities and Exchange Commission on March 13, 2025 (as amended, the "Schedule 13D"). This Amendment No. 3 supplements Item 4 and amends and restates Item 5(a)-(c) as set forth below. Capitalized terms used herein and not otherwise defined in this Amendment No. 3 have the meanings set forth in the Schedule 13D.

**Item 4. Purpose of Transaction**

The Reporting Persons intend to continue preliminary discussions with the Issuer regarding a potential financing transaction involving the issuance of convertible bonds (the "Bonds") by a newly formed subsidiary of the Issuer (the "Bond Issuer"). The proposed transaction contemplates a financing of at least $10.0 million from a consortium of investors led by the Reporting Persons. The proceeds of the financing are intended to be used to advance the Issuer's CMC and clinical trials for v2.0 process development and GMP manufacturing. The terms currently under discussion provide that the Bonds would be convertible into common equity of the Bond Issuer or exchangeable for Common Stock of the Issuer. The transaction is subject to certain closing conditions and the Bonds would be subject to certain negative pledges and covenants.

The Reporting Persons also intend to engage in preliminary discussions with the Issuer in connection with certain restructuring or merger and acquisition transactions involving the parties, and the terms and conditions thereof, certain of which may include, without limitation, changes to the Issuer's capital structure or any of the matters set forth in clauses (a)-(j) of Item 4 of Schedule 13D.

The percentage set forth on row (13) and the number of shares of Common Stock set forth on rows (8), (10) and (11) give effect to the 45% beneficial ownership limitation cap.

**(b)**
See rows (7) through (10) of the cover page to this Schedule 13D for the shares of Common Stock as to which the Reporting Persons have the sole or shared power to vote or direct the vote and sole or shared power to dispose or to direct the disposition.
