Item 1.

Security and Issuer

 

This Amendment No. 1 (the “Amendment”) amends and supplements the Schedule 13D filed by the Reporting Person with the Securities and Exchange Commission on March 8, 2021. This Schedule 13D, as amended and restated (the “Schedule 13D”) relates to shares of common stock, par value $0.0001 per share (the “Common Stock”), of Adicet Bio, Inc. (the “Issuer”). The Issuer’s principal executive offices are located at 500 Boylston Street, 12^th Floor, Boston, MA 02116. This Amendment is being filed to correct the number of shares of Common Stock held as reported on the original Schedule 13D filed on March 8, 2021. Except as specifically provided herein, this Amendment does not modify or amend any of the information previously reported in the Schedule 13D. Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to such terms in the Schedule 13D.  Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable.
