This amendment No. 2 to Schedule 13D amends and supplements the Schedule 13D filed with the SEC on October 15, 2020 and amendment No. 1 to the Schedule 13D filed with the SEC on December 21, 2023 (collectively, the “Prior Schedule 13D”) by Redmile Group, LLC, Jeremy C. Green, and Redmile Biopharma Investments II, L.P. relating to the Common Stock of the Issuer.

ITEM 3.

Source and Amount of Funds or Other Consideration.

Item 3 of the Prior Schedule 13D is hereby amended and supplemented by adding the following paragraph immediately after the last paragraph of Item 3:

On December 4, 2024, certain private investment vehicles managed by Redmile, including Redmile Biopharma Investments II, L.P. (“RBI II” and collectively with the other private investment vehicles managed by Redmile, the “Redmile Clients”), engaged in cross trades with respect to 1,026,888 shares of Common Stock. RBI II also purchased 133,371 shares of Common Stock and certain other Redmile Clients sold 133,371 shares of the Issuer’s Common Stock, in each case, concurrently with the cross trades at the same price. The reported transactions occurred simultaneously, at which time the price per share of the Common Shares was $1.25 per share. The source of funds for the concurrent purchases of Common Stock by RBI II was the working capital of RBI II. For the avoidance of doubt, the reported transactions resulted in no realized profit to Redmile or Jeremy Green and the cross trades and other transactions resulted in no change to the aggregate beneficial ownership of Redmile or Mr. Green.

ITEM 5.

Interest in Securities of the Issuer.

Item 5 of the Prior Schedule 13D is hereby amended and restated in its entirety as follows:

(a) The aggregate amount of shares of Common Stock that may be deemed beneficially owned by the Reporting Persons is comprised of the following: (i) 456,784 shares of Common Stock held by Redmile Capital Fund, L.P., (ii) 494,932 shares of Common Stock held by Redmile Capital Offshore Master Fund, Ltd., (iii) 374,149 shares of Common Stock held by Redmile Capital Offshore II Master Fund, Ltd., (iv) 301,022 shares of Common Stock and a Warrant (as defined below) to purchase 1,233,414 shares of Common Stock held by Redmile Strategic Long Only Trading Sub, Ltd., (v) 467,910 shares of Common Stock and a Warrant to purchase 316,997 shares of Common Stock held by Redmile Strategic Trading Sub, Ltd., (vi) 3,338,997 shares of Common Stock and a Warrant to purchase 1,550,412 shares of Common Stock held by Redmile Biopharma Investments II, L.P., and (vii) 105,930 shares of Common Stock held by RedCo I, L.P. Redmile is the investment manager/adviser to each of the Redmile Clients listed in items (i) through (vii) and, in such capacity, exercises voting and investment power over all of the securities held by the Redmile Clients and may be deemed to be the beneficial owner of these securities. Jeremy C. Green serves as the managing member of Redmile and also may be deemed to be the beneficial owner of these shares. Redmile and Mr. Green each disclaim beneficial ownership of these securities, except to the extent of its or his pecuniary interest in such shares, if any.

Subject to the Beneficial Ownership Blocker (as defined below), Redmile and Mr. Green may be deemed to beneficially own the 3,100,823 shares of Common Stock issuable upon exercise of certain pre-funded warrants to purchase Common Stock (the “Warrants”) described in the preceding paragraph. Pursuant to the terms of the Warrants, the Common Stock that may be acquired upon exercise of the Warrants shall be limited to the extent that, following such exercise, the total number of shares of Common Stock then beneficially owned by the holder of the Warrants, together with such holder’s affiliates and any other person whose beneficial ownership of Common Stock would be aggregated with such holder’s for the purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), would exceed the Beneficial Ownership Limitation (the “Beneficial Ownership Blocker”). The “Beneficial Ownership Limitation” is 9.99% of the shares of Common Stock then issued and outstanding, which percentage may be changed at a holder’s election upon 61 days’ notice to the Issuer. Because the percentage of shares of Common Stock held directly by the Redmile Clients at the time of this filing exceeds 9.99% in the aggregate, the exercise of the Warrants held by Redmile Clients are limited in their entirety by the Beneficial Ownership Blocker and the Reporting Persons therefore cannot be deemed to have beneficial ownership of any of the shares of Common Stock issuable upon exercise of the Warrants and such shares have not been included in the aggregate amount of securities reported in this Schedule 13D.

- 5 -

Redmile and Mr. Green may also be deemed to beneficially own 85,236 shares of Common Stock subject to options to purchase shares of Common Stock that are exercisable within 60 days of the date of this filing. The stock options were granted to Mike Lee, a managing director of Redmile, in connection with his service as a member of the Board of Directors of the Issuer. Pursuant to the policies of Redmile, Mr. Lee holds the stock options as a nominee on behalf, and for the sole benefit, of Redmile and has assigned all economic, pecuniary and voting rights in respect of the stock options to Redmile.

For purposes of this Schedule 13D, the percent of class calculated based on 47,739,708 shares of Common Stock outstanding on November 1, 2024, as disclosed in the Issuer’s Quarterly Report for the quarterly period ended September 30, 2024 filed on Form 10-Q with the SEC on November 14, 2024.
