Item 4

Ownership:

Items 5 through 9 and 11 of each of the cover pages to this Amendment No. 2 are incorporated herein by reference. Set forth below is the aggregate number of shares of Common Stock of the Issuer directly held by each of 667, L.P. (“667”) and Baker Brothers Life Sciences, L.P. (“Life Sciences”, and together with 667, the “Funds”), which may be deemed to be indirectly beneficially owned by the Reporting Persons, as well as shares of Common Stock that may be acquired upon the exercise of the Prefunded Warrants (as defined below), subject to the limitations on exercise described below.

The information set forth below is based upon 68,321,396 shares of Common Stock outstanding as of August 5, 2024, as reported in the Issuer’s Form 10-Q filed with the Securities and Exchange Commission on August 8, 2024. Such percentage figures are calculated in accordance with Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Name	Number of Shares of Common Stock we own or have the right to acquire within 60 days		Percent of Class Outstanding
667, L.P.		929,241		1.4	%
Baker Brothers Life Sciences, L.P.		10,116,095		14.8	%
Total		11,045,336		16.2	%

The Funds hold warrants issued in 2020 and 2022 to purchase shares of Common Stock that are exercisable at any time on a 1-for-1 basis into Common Stock at an exercise price of $0.0001 per share with no expiration date (the “$0.0001 Prefunded Warrants”). The $0.0001 Prefunded Warrants are only exercisable to the extent that after giving effect or immediately prior to such exercise the holders thereof, their affiliates and any person who are members of a Section 13(d) group with the holders or one of their affiliates would beneficially own in the aggregate, for purposes of Rule 13d-3 under the Exchange Act, no more than 4.99% of the outstanding Common Stock (the “$0.0001 Maximum Percentage”). By written notice to the Issuer, the Funds may from time to time increase or decrease the $0.0001 Maximum Percentage applicable to that Fund to any other percentage not in excess of 19.99%. Any such increase or decrease will not be effective until the 61st day after such notice is delivered to the Issuer. Due to the $0.0001 Maximum Percentage, the Funds cannot presently exercise any shares of $0.0001 Prefunded Warrants.

The Funds hold warrants issued in 2024 to purchase shares of Common Stock that are exercisable at any time on a 1-for-1 basis into Common Stock at an exercise price of $0.001 per share with no expiration date (the “$0.001 Prefunded Warrants” and together with the $0.0001 Prefunded Warrants, the “Prefunded Warrants”). The $0.001 Prefunded Warrants are only exercisable to the extent that after giving effect or immediately prior to such exercise the holders thereof, their affiliates and any person who are members of a Section 13(d) group with the holders or one of their affiliates would beneficially own in the aggregate, for purposes of Rule 13d-3 under the Exchange Act, no more than 9.99% of the outstanding Common Stock (the “$0.001 Maximum Percentage”). By written notice to the Issuer, the Funds may from time to time increase or decrease the $0.001 Maximum Percentage applicable to that Fund to any other percentage not in excess of 9.99%. Any such increase or decrease will not be effective until the 61st day after such notice is delivered to the Issuer. Due to the $0.001 Maximum Percentage, the Funds cannot presently exercise any shares of $0.001 Prefunded Warrants.

As a result of these restrictions, the number of shares of Common Stock that may be issued upon exercise of the Prefunded Warrants by the above holders may change depending upon changes in the outstanding Common Stock.

Pursuant to the management agreements, as amended, among the Adviser, the Funds and their respective general partners, the Funds’ respective general partners relinquished to the Adviser all discretion and authority with respect to the investment and voting power of the securities held by the Funds, and thus the Adviser has complete and unlimited discretion and authority with respect to the Funds’ investments and voting power over investments.

The Adviser GP is the sole general partner of the Adviser. The Adviser GP, Felix J. Baker and Julian C. Baker as managing members of the Adviser GP, and the Adviser may be deemed to be beneficial owners of securities of the Issuer directly held by the Funds.
