Item 1.

Security and Issuer

Item 1 is amended and replaced in its entirety as follows:

This amendment (“Amendment No. 3”) amends the Schedule 13D originally filed with the SEC on August 13, 2020, as subsequently amended by Amendment No. 1 filed on November 1, 2021 and Amendment No. 2 filed on May 11, 2022 (collectively, the “Schedule”), to report and reflect that Novo Holdings A/S ceased to be a beneficial owner of the Issuer’s Common Stock. All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Schedule

Item 3.

Source and Amount of Funds or Other Consideration

Item 3 is amended and replaced in its entirety as follows:

On April 19, 2022, Checkmate Pharmaceuticals, Inc., a Delaware corporation (the “Issuer”), filed an 8-K with the Securities and Exchange Commission disclosing an Agreement and Plan of Merger, by and among the Issuer and Regeneron Pharmaceuticals, Inc. (“Regeneron”). On May 31, 2022, Regeneron completed a cash tender offer to purchase, subject to certain conditions, any and all of the outstanding shares of common stock of the Issuer at a price per share of $10.50 (the “Tender Offer”). Novo Holdings A/S tendered all of its 1,670,100 shares of the Issuer’s common stock to Regeneron in the Tender Offer. Regeneron accepted all tendered shares in the Tender Offer on June 2, 2022, for an aggregate purchase price to Novo Holdings A/S of approximately $17,536,050. Following the acceptance by Regeneron of all tendered shares in the Tender Offer, Novo Holdings A/S no longer held any shares of the Issuer.
