This Amendment No. 7 to the Schedule 13D is being filed by Perceptive Advisors LLC (“Perceptive Advisors”), Joseph Edelman (“Mr. Edelman”) and Perceptive Life Sciences Master Fund, Ltd. (the “Master Fund,” and together with Perceptive Advisors and Mr. Edelman, each of the foregoing, a “Reporting Person,” and collectively, the “Reporting Persons”). Perceptive Advisors serves as the investment advisor to the Master Fund and Mr. Edelman is the managing member of Perceptive Advisors. The agreement among the Reporting Persons to file this Schedule 13D jointly in accordance with Rule 13d-1(k) of the Securities Exchange Act of 1934, as amended, is attached as Exhibit 1 to the initial Schedule 13D filed May 18, 2023.

The address of the principal business office of each of the Reporting Persons is 51 Astor Place 10th Floor, New York, NY 10003.

The principal business of Perceptive Advisors is managing funds in connection with purchasing, holding and selling securities for investment purposes. The principal business of the Master Fund is to invest in securities. The principal occupation of Mr. Edelman is as the managing member of Perceptive Advisors and other related entities.

During the last five years, none of the Reporting Persons, nor to the Reporting Persons’ knowledge, any of the persons listed on Schedule A to this Amendment No. 7 to Schedule 13D, has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

During the last five years, none of the Reporting Persons, nor to the Reporting Persons’ knowledge, any of the persons listed on Schedule A to this Amendment No. 7 to Schedule 13D, has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree of final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws, other than the previously announced settlement order entered into by Perceptive Advisors with the Securities and Exchange Commission dated September 6, 2022 (File No. 3-21031).

Perceptive Advisors is a Delaware limited liability company. Mr. Edelman is a United States citizen. The Master Fund is a Cayman Islands corporation.

The information set forth in rows 11 and 13 of the cover pages to this Amendment No. 7 to Schedule 13D is incorporated by reference and assumes the exercise of pre-funded warrants held by the Reporting Persons to purchase 250,000 shares of the Issuer’s Common Stock (the “Pre-Funded Warrants”). The terms of the Pre-Funded Warrants provide that the Pre-Funded Warrants may not be exercised if, after such exercise, the Reporting Persons would beneficially own, as determined in accordance with Section 13(d) if the Securities Exchange Act of 1934, as amended, more than 9.99% of the shares of Common Stock then issued and outstanding after giving effect to such exercise (the “Beneficial Ownership Limitation”). As of the date hereof, the Beneficial Ownership Limitation permits the Reporting Persons to exercise all of its Pre-Funded Warrants for an aggregate of 250,000 shares of Common Stock. The percentage set forth in row 13 is based on 38,871,594 shares of Common Stock outstanding as of August 2, 2024, as reported by the Issuer in its Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on August 7, 2024, and assumes the exercise of the Pre-Funded Warrants.

The information set forth in rows 7 through 10 of the cover pages to this Amendment No. 7 to Schedule 13D is incorporated by reference and assumes the exercise of the Pre-Funded Warrants.

Except as set forth on Schedule B, no Reporting Person has effected any transaction in shares of Common Stock in the past sixty days.
