The following constitutes Amendment No. 4 to the Schedule 13D filed by the undersigned (“Amendment No. 4”). This Amendment No. 4 amends the Schedule 13D as specifically set forth herein.

Item 3.Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated to read as follows:

The Shares beneficially owned by BVF, BVF2 and Trading Fund OS and held in the Partners Managed Account were purchased with working capital (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business) in open market purchases, except as otherwise noted.

The aggregate purchase price of the 2,656,191 Shares directly beneficially owned by BVF is approximately $57,393,095, including brokerage commissions. The aggregate purchase price of the 550,425 pre-funded warrants (the “Pre-Funded Warrants”) owned by BVF, which BVF acquired in the Issuer’s public offering priced on January 5, 2024 (the “Offering”), is approximately $13,898,176.

The aggregate purchase price of the 2,104,075 Shares directly beneficially owned by BVF2 is approximately $44,181,738, including brokerage commissions. The aggregate purchase price of the 375,856 Pre-Funded Warrants owned by BVF2, which BVF2 acquired in the Offering, is approximately $9,490,326.

The aggregate purchase price of the 294,632 Shares directly beneficially owned by Trading Fund OS is approximately $5,346,778, including brokerage commissions. The aggregate purchase price of the 52,733 Pre-Funded Warrants owned by Trading Fund OS, which Trading Fund OS acquired in the Offering, is approximately $1,331,503.

The aggregate purchase price of the 106,903 Shares held in the Partners Managed Account is approximately $1,876,596, including brokerage commissions. The aggregate purchase price of the 11,085 Pre-Funded Warrants held in the Partners Managed Account, which the Partners Managed Account acquired in the Offering, is approximately $279,895.

Stock options held by Mr. Hrustanovic referencing 40,127 Shares, 20,063 Shares, 12,000 Shares and 12,000 Shares, 72,190 Shares of which Mr. Hrustanovic may be deemed to beneficially own, were awarded to him on August 20, 2020, June 16, 2021, June 15, 2022 and June 15, 2023, respectively, for no consideration in connection with his service on the Board. Pursuant to a certain agreement entered into between Partners and Mr. Hrustanovic, Mr. Hrustanovic is obligated to transfer the economic benefit, if any, received upon the sale of the Shares issuable upon exercise of the above referenced stock options to Partners.

Item 5.Interest in Securities of the Issuer.

Items 5(a) – (c) are hereby amended and restated to read as follows:

(a)       The aggregate percentage of Shares reported owned by each person named herein is based upon a denominator that is the sum of: (i) 57,700,734 Shares outstanding as of January 9, 2024, which is the total number of Shares outstanding following the closing of the Offering as reported in the Issuer’s prospectus supplement on Form 424B5 filed with the Securities and Exchange Commission on January 5, 2024 (the “Prospectus Supplement”), and (ii) certain or all of the 669,370 Shares underlying the Pre-Funded Warrants held by the Reporting Persons that are currently exercisable, as applicable.
