SCHEDULE 13D/A
Item 1. Security and Issuer
Item 1 of the Statement is hereby amended and supplemented as follows:
This Amendment No. 4 amends and supplements the statement on Schedule 13D originally filed with the Securities and Exchange Commission on May 6, 2021, as amended by Amendment No. 1 filed on June 16, 2021, Amendment No. 2 filed on August 12, 2022 and Amendment No. 3 filed on January 10, 2023 (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. 4 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”) who are collectively referred to herein as the “Reporting Persons.” |
The Reporting Persons’ ownership of the Issuer’s securities include (1) 5,701,056 shares of Common Stock held by the Fund, (2) 443,825 shares of Common Stock held by the RA Capital Nexus Fund II, L.P. (the “Nexus Fund II”), (3) a total of 32,866 vested stock options (right to buy), an d (4) 1,288 stock options (right to buy) which shall vest within 60 days of this filing.
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 the Fund and the Nexus Fund II and may be deemed a beneficial owner, for purposes of Section 13(d) of the Securities Exchange Act of 1934 (the “Act”), of any securities of the Issuer held by the Fund or the Nexus Fund II. The Fund and the Nexus Fund II have delegated to RA Capital the sole power to vote and the sole power to dispose of all securities held in the Fund’s and the Nexus Fund II’s portfolio, including the shares of the Issuer’s Common Stock reported herein. Because the Fund and the Nexus Fund II have divested themselves of voting and investment power over the reported securities they hold and may not revoke that delegation on less than 61 days’ notice, the Fund and the Nexus Fund II disclaim beneficial ownership of the securities they hold for purposes of Section 13(d) of the Act and therefore disclaim any 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 Statement other than for the purpose of determining their obligations under Section 13(d) of the Act, and the filing of the Statement 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 Dr. Kolchinsky and Mr. Shah is investment management. |
| CUSIP No. 95075A107 | 13D/A |
| (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 Statement is incorporated herein by reference. The percentages set forth in row 13 of the cover pages are based on 40,660,732 outstanding shares of Common Stock of the Issuer as of January 31, 2024, as reported in the Issuer’s Form 8-K filed with the Securities and Exchange Commission (“SEC”) on February 9, 2024 plus, as applicable, an aggregate of 34,154 shares underlying vested stock options and stock options which will vest within 60 days. |
| (b) | The information set forth in rows 7 through 10 of the cover pages to this Statement and Item 2 above is incorporated herein by reference. |
| (c) | The following table lists the Reporting Persons’ transactions in Common Stock that were effected during the sixty day period prior to the filing of this Schedule 13D/A5: |
| Transaction | Purchaser | Date | No. Shares | Price |
| Vest Stock Option (Right to Buy) | RA Capital | December 30, 2023 | 644 | (1) |
| Vest Stock Option (Right to Buy) | RA Capital | January 30, 2024 | 644 | (1) |
| Vest Stock Option (Right to Buy) | RA Capital | February 29, 2024 | 644 | (1)* |
| Vest Stock Option (Right to Buy) | RA Capital | March 30, 2024 | 644 | (1)* |
| (1) | This option represents a right to purchase a total of 23,200 shares of the Issuer's Common Stock, one third of which vested on April 30, 2022, with the remaining two-thirds vesting in equal monthly installments over the following two years, subject to Dr. DiRocco’s continued service to the Issuer through each vesting date. These options have an exercise price of $16.00. |
| * | Represents future vesting within 60 days from the filing date of this Schedule 13D/A. |
| (d) | No person (other than the Reporting Persons) is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Common Stock subject to this Statement. |
| (e) | Not applicable. |
5 The Common Stock and percentage ownership reported in this amendment reflect an increase in the number of outstanding shares of the Issuer. The vesting options in Item 5(c) did not cause a material change in the Reporting Persons’ beneficial ownership.
