The following constitutes Amendment No. 1 to the Schedule 13D filed by the undersigned (“Amendment No. 1”). This Amendment No. 1 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 Accounts 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 Shares beneficially owned by BVF is approximately $14,407,167, including brokerage commissions. The aggregate purchase price of the Shares beneficially owned by BVF2 is approximately $10,502,043, including brokerage commissions. The aggregate purchase price of the Shares beneficially owned by Trading Fund OS is approximately $1,682,523, including brokerage commissions. The aggregate purchase price of the Shares beneficially owned by the Partners Managed Accounts is approximately $1,449,055, including brokerage commissions.

The aggregate purchase price of the non-voting common stock directly owned by BVF is approximately $10,876,185, including brokerage commissions. The aggregate purchase price of the non-voting common stock directly owned by BVF2 is approximately $7,939,807, including brokerage commissions. The aggregate purchase price of the non-voting common stock directly owned by Trading Fund OS is approximately $1,641,127, including brokerage commissions.

Pursuant to a certain agreement entered into between Partners and Dr. Hrustanovic, Dr. Hrustanovic is obligated to transfer the economic benefit, if any, received upon the sale of the Shares issuable upon exercise of the above referenced options to Partners. As of the date hereof, Dr. Hrustanovic does not beneficially own any Shares.

Item 5.Interest in Securities of the Issuer.

Item 5 is hereby amended and restated to read as follows:

(a)       The aggregate percentage of Shares reported owned by each person named herein is based on 18,241,690 Shares outstanding, which is the total number of Shares outstanding following the Issuer’s IPO as disclosed in the Issuer’s Prospectus on Form 424(b)(4) filed with the Securities and Exchange Commission on April 23, 2021.

As of the date hereof, BVF beneficially owns, subject to the limitation described below, 1,900,815 shares of non-voting common stock and 941,300 Shares. As of the close of business on May 25, 2021, the Beneficial Ownership Limitation limits the aggregate conversion of the non-voting common stock by BVF to 0 out of the 1,900,815 Shares underlying the non-voting common stock, resulting in percentage ownership of approximately 5.2%.

As of the date hereof, BVF2 beneficially owns, subject to the limitation described below, 1,390,756 shares of non-voting common stock and 686,372 Shares. As of the close of business on May 25, 2021, the Beneficial Ownership Limitation limits the aggregate conversion of the non-voting common stock by BVF2 to 0 out of the 1,390,756 Shares underlying the non-voting common stock, resulting in percentage ownership of approximately 3.8%.

As of the date hereof, Trading Fund OS beneficially owns, subject to the limitation described below, 286,691 shares of non-voting common stock and 112,482 Shares. As of the close of business on May 25, 2021, the Beneficial Ownership Limitation limits the aggregate conversion of the non-voting common stock by Trading Fund OS to 0 out of the 286,691 Shares underlying the non-voting common stock, resulting in percentage ownership of less than 1%.
