This Schedule 13D is being filed by the following persons (each a “Reporting Person” and together the “Reporting Persons”):

1.	HealthCap VII, L.P., a Delaware limited partnership (the “Fund”); and

2.	HealthCap VII GP S.A., a corporation organized under the laws of Switzerland (the “General Partner”), which is the sole general partner of the Fund.

The principal business address of each Reporting Person is c/o HealthCap VII GP S.A., 23 Avenue Villamont, Lausanne, Switzerland CH 1005. The principal business of the Reporting Persons and the Managers (as defined below) is venture capital investment focused on the health care sector.

During the last five years, none of the Reporting Persons or the Managers has been party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding were or are subject to a judgment, decree or 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.

The Reporting Persons have entered into a Joint Filing Agreement, dated as of the date hereof, a copy of which is filed with this Schedule 13D as Exhibit 1.01, pursuant to which the Reporting Persons have agreed to file this statement jointly in accordance with the provisions of Rule 13d-1(k) under the Act.

Item 3. Source and Amount of Funds or Other Consideration.

As more fully described in Items 4 and 6 below, on September 20, 2022, Sesen Bio, Inc., a Delaware corporation (“Sesen Bio”), Seahawk Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Sesen Bio (“Merger Sub”), and CARISMA Therapeutics Inc., a Delaware corporation (“Carisma”), entered into an Agreement and Plan of Merger and Reorganization (as amended from time to time, the “Merger Agreement”), pursuant to which, among other things, and subject to the satisfaction or waiver of certain conditions set forth in the Merger Agreement, Merger Sub merged with and into Carisma, with Carisma continuing as a wholly-owned subsidiary of Sesen Bio and the surviving corporation of the merger (the “Merger”). At the effective time of the Merger, Sesen Bio filed an amendment to its certificate of incorporation, to change its name to “CARISMA Therapeutics Inc.”

Page 6 of 10

Prior to the Merger, the Fund owned 1,485,912 of Carisma’s capital stock, consisting of (i) 250,647 shares of Carisma common stock issuable upon conversion of the Carisma Series A preferred stock (“Series A Conversion Shares”), acquired pursuant to the Series A Preferred Stock Purchase Agreement, dated June 26, 2018, by and among Carisma, CARISMA Therapeutics S.à r.l., a société à responsabilité limitée organized under the laws of Luxembourg, and the investors listed therein, including the Fund (the “Series A SPA”), (ii) 937,501 shares of Carisma common stock issuable upon the conversion of the Carisma special voting preferred stock (“Special Voting Conversion Shares”), acquired pursuant to the Series A SPA, and (iii) 297,764 shares of Carisma common stock issuable upon the conversion of the Carisma Series B special voting preferred stock (“Series B Conversion Shares,” and together with Series A Conversion Shares and Special Voting Conversion Shares, collectively, the “Pre-Merger Carisma Shares”), acquired pursuant to the Series B Preferred Stock Purchase Agreement, dated December 22, 2020, by and among Carisma, CARISMA Therapeutics S.à r.l., a société à responsabilité limitée organized under the laws of Luxembourg, and the investors listed therein, including the Fund (the “Series B SPA”), held by the Fund. The Pre-Merger Carisma Shares were acquired by the Fund using funds obtained from working capital.

Pursuant to the Merger Agreement, upon the effectiveness of the Merger, each outstanding Pre-Merger Carisma Share was converted into the right to receive a number of shares of Sesen Bio common stock calculated in accordance with the Merger Agreement. Cash was paid in lieu of fractional shares. Accordingly, the Fund now owns 3,579,611 shares of the common stock of the combined company.

The foregoing references to and descriptions of the Merger Agreement and the transactions contemplated thereby, do not purport to be complete and are subject to, and are qualified in their entirety by reference to, the full text of the Merger Agreement, attached hereto as Exhibits 1.02-1.04 to include its amendments.

Item 4. Purpose of Transaction.

The Fund acquired the shares of Common Stock for investment purposes.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors, including but not limited to the Issuer’s financial position and strategic direction, price levels of its Common Stock, conditions in the securities markets, and general economic and industry conditions, the Reporting Persons may take actions with respect to their investment in the Issuer. These actions include changing their current investment purpose and/or, from time to time, (i) acquiring or causing affiliates to acquire additional shares in open market transactions, in privately negotiated transactions or through other methods; (ii) disposing or causing affiliates to dispose of some or all of the shares in open market transactions, in privately negotiated transactions or through other methods, including distributions by the Fund directly to its limited partners; or (iii) continuing to hold or causing affiliates to hold the shares (or any combination or derivative thereof). In addition, the Reporting Persons may engage in discussions with the Issuer’s management, members of its board of directors, stockholders and other relevant parties or take other actions concerning the Issuer’s operations, capital expenditures, financings, executive compensation practices, capital structure and any matter set forth in paragraphs (a) through (j) of Item 4 of Schedule 13D.
