This Amendment No. 2 (“Amendment No. 2”) amends and supplements the amended statement on Schedule 13D (“Amendment No. 1”) filed on January 4, 2022 by Boxer Capital, LLC (“Boxer Capital”), Boxer Asset Management Inc. (“Boxer Management”), Joe Lewis, MVA Investors, LLC (“MVA Investors”), Aaron I. Davis, BCTG Holdings, LLC (“BCTG Holdings”), and, as its original filing on Schedule 13D regarding the Issuer, Braslyn Ltd. (“Braslyn) (together, the “Reporting Persons”), which, in respect of the Reporting Persons other than Braslyn, amended and supplemented the original statement on Schedule 13D filed by them on August 20, 2021 (as previously amended, the “Original Filing”). The Original Filing remains in effect except to the extent that it is amended, restated or superseded by information contained in this Amendment No. 2. Capitalized terms used and not defined in this Amendment No. 2 have the meanings set forth in the Original Filing.
Item 3.    Source and Amount of Funds or Other Consideration.
Item 3 is hereby amended to add the following:
On August 11, 2023, MVA Investors, using funds on hand, purchased 475,000 shares of Common Stock at a price of $5.15 per share from the Issuer in a private placement for an aggregate purchase price of $2,446,250, pursuant to a securities purchase agreement dated August 10, 2023 (“Private Placement”). In connection with the Private Placement, Boxer Capital purchased 2,340,579 prefunded warrants (the “Prefunded Warrants”) at a cash purchase price of $5.1499 per each Prefunded Warrant for an aggregate purchase price of $12,053,747.79. The Prefunded Warrants have an exercise price of $0.0001 per share of Common Stock and are immediately exercisable and remain exercisable in full; provided, that, the Prefunded Warrants are subject to a limitation (the “Blocker”) that prohibits the Reporting Persons from exercising the Prefunded Warrants if the result would cause their aggregate beneficial ownership of Common Stock to exceed 9.99% of the Common Stock then outstanding. As a result of the Blocker, the Prefunded Warrants cannot now be exercised by the Reporting Persons and do not give them beneficial ownership of shares of Common Stock.
Item 4.    Purpose of Transaction.
Item 4 is hereby amended to add the following:
Pursuant to the Private Placement, MVA Investors purchased 475,000 shares of Common Stock at a price of $5.15 per share for an aggregate purchase price of $2,446,250. In connection with the Private Placement, Boxer Capital purchased 2,340,579 prefunded warrants (the “Prefunded Warrants”) at a purchase price of $5.1499 per each Prefunded Warrant for an aggregate purchase price of $12,053,747.79. The Prefunded Warrants have an exercise price of $0.0001 per share of Common Stock and are immediately exercisable and remain exercisable in full; provided, that, the Prefunded Warrants are subject to the Blocker. As a result of the Blocker, the Prefunded Warrants cannot now be exercised by the Reporting Persons and do not give them beneficial ownership of shares of Common Stock.
