Sensei Biotherapeutics Acquires Faeth Therapeutics and Raises $200M

Sensei Biotherapeutics announced that it has acquired Faeth Therapeutics. The acquisition brings Faeth's lead asset Piktor, into Sensei's pipeline. Concurrent with the acquisition, Sensei entered into a definitive agreement for the sale of Series B non-voting convertible preferred stock in a private placement financing, which is expected to result in gross proceeds to Sensei of approximately $200M before deducting placement agent and other offering expenses. The financing included participation from B Group Capital, Balyasny Asset Management, Columbia Threadneedle Investments, Cormorant Asset Management, Fairmount, Logos Capital, RA Capital Management, Vivo Capital, multiple leading life sciences funds, and other institutional investors. Sensei expects to use the proceeds primarily to advance Piktor through key clinical milestones, including topline data from an ongoing Phase 2 trial in second-line advanced endometrial cancer, as well as the initiation of a Phase 1b trial in HR+/HER2- advanced breast cancer, both expected by year end 2026, with remaining proceeds for general corporate purposes and completion of Sensei's ongoing Phase 1/2 trial of solnerstotug.
