Item 1. Security and Issuer

This Amendment No. 2 amends and supplements the statement on Schedule 13D originally filed with the Securities and Exchange Commission (the “SEC”) on September 6, 2024 and Amendment No. 1 on September 13, 2024 (as amended, the “Statement” or the “Schedule 13D”) by the Reporting Persons with respect to the Common Stock of the Company.

Unless amended or supplemented below, the information in the Statement remains unchanged. The address of the principal executive offices of the Company is 855 Oak Grove Avenue, Suite 100, Menlo Park, CA 94025.

Item 2. Identity and Background

(a)

This Schedule 13D is being filed jointly by (1) Fairmount; (2) Fund II; (3) Co-Invest; (4) Peter Harwin; and (5) Tomas Kiselak (Mr. Harwin and Mr. Kiselak, Fairmount, Fund II, and Co-Invest are collectively referred to herein as the “Reporting Persons”). The joint filing agreement of the Reporting Persons is attached as Exhibit 99.1 to this Schedule 13D.

Fairmount serves as investment manager for Fund II and Co-Invest and may be deemed a beneficial owner, for purposes of Section 13(d) of the Securities Exchange Act of 1934 (the “Act”), of any securities of the Company held by Fund II and Co-Invest. Fund II and Co-Invest have delegated to Fairmount the sole power to vote and the sole power to dispose of all securities held in Fund II’s and Co-Invest’s portfolio, including the shares of Common Stock reported herein. Because Fund II and Co-Invest have divested themselves of voting and investment power over the reported securities they hold and may not revoke that delegation on less than 61 days’ notice, Fund II and Co-Invest disclaim beneficial ownership of the securities they hold for purposes of Section 13(d) of the Act and therefore disclaim any obligation to report ownership of the reported securities under Section 13(d) of the Act. The general partner of Fairmount is Fairmount Funds Management GP LLC (“Fairmount GP”). As managing members of Fairmount GP, Mr. Harwin and Mr. Kiselak may be deemed beneficial owners, for purposes of Section 13(d) of the Act, of any securities of the Company beneficially owned by Fairmount. Fairmount, Fairmount GP, Mr. Harwin and Mr. Kiselak disclaim beneficial ownership of the securities reported in this Schedule 13D other than for the purpose of determining their obligations under Section 13(d) of the Act, and the filing of this Schedule 13D shall not be deemed an admission that any of Fairmount, Fairmount GP, Mr. Harwin or Mr. Kiselak is the beneficial owner of such securities for any other purpose.

(b)

The principal business address of each of the Reporting Persons is 200 Barr Harbor Drive, Suite 400, West Conshohocken, PA 19428.

(c)

The principal business of Fairmount is to provide discretionary investment management services to qualified investors through Fund II and Co-Invest, which are each private pooled investment vehicles. The principal occupation of Mr. Harwin and Mr. Kiselak is investment management.

(d)(e)

The exercise of the Pre-Funded Warrants is subject to a beneficial ownership limitation of 9.99% of the outstanding Common Stock and the conversion of the Series B Preferred Stock is subject to a beneficial ownership limitation of 19.99%. The securities exclude shares of Common Stock issuable upon exercise of Pre-Funded Warrants and conversion of shares of Series B Preferred Stock in excess of such beneficial ownership limitations. At such time as Fairmount and its affiliates beneficially own 9.0% or less of the Common Stock, the beneficial ownership limitation with respect to the Series B Preferred Stock will automatically reduce to 9.99%.

Pursuant to the terms of the Certificate of Designation of Preferences, Rights and Limitations of Series A Non-Voting Convertible Preferred Stock, dated September 12, 2024 (the “Certificate of Designation”), following stockholder approval received on November 14, 2024 of the issuance of shares of Common Stock upon conversion of the Series A Preferred Stock, each share of Series A Preferred Stock automatically converted into 1,000 shares of Common Stock.

The securities exclude shares of Common Stock issuable upon exercise of Pre-Funded Warrants and conversion of shares of Series B Preferred Stock in excess of such beneficial ownership limitations.
