Item 1.Security and Issuer

 

Item 1 of the Statement is hereby amended and supplemented as follows:

 

This Amendment No. 5 (this “Amendment No. 5” or this “Schedule 13D/A”) amends and supplements the statement on Schedule 13D originally filed with the Securities and Exchange Commission (the “SEC”) on May 6, 2021, as amended by Amendment No. 1 filed on June 16, 2021, Amendment No. 2 filed on August 12, 2022, Amendment No. 3 filed on January 10, 2023 and Amendment No. 4 filed on February 14, 2024 (as amended, the “Statement”) by the Reporting Persons with respect to the Common Stock, $0.0001 par value (the “Common Stock”), of Werewolf Therapeutics, Inc. (the “Issuer”). Unless otherwise defined herein, capitalized terms used in this Amendment No. 5 shall have the meanings ascribed to them in the Statement. Unless amended or supplemented below, the information in the Statement remains unchanged.

 

Item 2.Identity and Background

 

Item 2 of the Statement is hereby amended and restated as follows:

 

(a)This Schedule 13D/A is being filed on behalf of RA Capital Management, L.P. (“RA Capital”), Peter Kolchinsky, Rajeev Shah, and RA Capital Healthcare Fund, L.P. (the “Fund”). RA Capital, Dr. Kolchinsky, Mr. Shah and the Fund are collectively referred to herein as the “Reporting Persons.” The agreement among the Reporting Persons to file this Schedule 13D/A jointly in accordance with Rule 13d-1(k) of the Securities Exchange Act of 1934, as amended, (the “Act”) is attached hereto as Exhibit 1.

 

The Reporting Persons’ beneficial ownership of the Issuer’s Common Stock consists of (i) 5,701,056 shares of Common Stock directly held by the Fund; (ii) 443,825 shares of Common Stock directly held by the RA Capital Nexus Fund II, L.P (the “Nexus Fund II”); (iii) a total of 34,800 vested stock options (right to buy) held by Derek DiRocco for the benefit of RA Capital; and (iv) 13,200 stock options (right to buy) scheduled to vest within 60 days of this filing held by Dr. DiRocco for the benefit of RA Capital.

 

RA Capital Healthcare Fund GP, LLC is the general partner of the Fund and RA Capital Nexus Fund II GP, LLC is the general partner of the Nexus Fund II. The general partner of RA Capital is RA Capital Management GP, LLC, of which Dr. Kolchinsky and Mr. Shah are the controlling persons. RA Capital serves as investment adviser for each of the Fund and the Nexus Fund II and may be deemed a beneficial owner, for purposes of Section 13(d) of the Act, of any securities of the Issuer held by the Fund or the Nexus Fund II. Each of the Fund and the Nexus Fund II has delegated to RA Capital the sole power to vote and the sole power to dispose of all securities held in its portfolio, including the shares of the Issuer’s Common Stock reported herein. Because each of the Fund and the Nexus Fund II has divested itself of voting and investment power over the reported securities it holds and may not revoke that delegation on less than 61 days’ notice, each of the Fund and the Nexus Fund II disclaims beneficial ownership of the securities it holds for purposes of Section 13(d) of the Act and therefore disclaims a ny obligation to report ownership of the reported securities under Section 13(d) of the Act. As managers of RA Capital, Dr. Kolchinsky and Mr. Shah may be deemed beneficial owners, for purposes of Section 13(d) of the Act, of any securities of the Issuer beneficially owned by RA Capital. RA Capital, Dr. Kolchinsky, and Mr. Shah disclaim beneficial ownership of the securities reported in this Schedule 13D/A other than for the purpose of determining their obligations under Section 13(d) of the Act, and the filing of this Schedule 13D/A shall not be deemed an admission that either RA Capital, Dr. Kolchinsky, or Mr. Shah is the beneficial owner of such securities for any other purpose.

 

(b)The address of the principal business office of each of the Reporting Persons is 200 Berkeley Street, 18th Floor, Boston, MA 02116.

 

(c)The Fund is a private investment vehicle. RA Capital provides investment management services to the Fund and the Nexus Fund II. The principal occupation of each of Dr. Kolchinsky and Mr. Shah is investment management.

 

(d)During the last five years, none of the Reporting Persons has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

 

(e)During the last five years, none of the Reporting Persons has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree of final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

(f)See Item 6 of the cover pages.

 

Item 5.Interest in Securities of the Issuer

 

Item 5 of the Statement is hereby amended and restated as follows:

 

(a)The information set forth in rows 11 and 13 of the cover pages to this Schedule 13D/A is incorporated by reference. The percentage set forth in row 13 is based on 43,455,367 shares of Common Stock outstanding as of April 29, 2024, as reported in the Issuer’s Quarterly Report on Form 10-Q filed with the SEC on May 3, 2024.

 

(b)The information set forth in rows 7 through 10 of the cover pages to this Schedule 13D/A and Item 2 above is incorporated by reference.
