Poseida Therapeutics Inc. is being bought out for $1.5 billion by partner Roche Holdings Inc. to develop allogeneic CAR T therapies to treat hematologic malignancies. The two companies began their collaboration in August 2022, a deal that brought Poseida $110 million up front and another $110 million in near-term milestone payments. With the acquisition, Roche plans to develop CAR T programs for solid tumors and autoimmune diseases with Poseida's genetic engineering platform and preclinical programs.

Poseida Therapeutics Inc. has updated progress made in its early-stage pipeline of differentiated T stem cell memory cell-rich allogeneic CAR T therapies in oncology and autoimmune diseases.

Poseida Therapeutics Inc. has received FDA clearance of its IND application for P-CD19CD20-ALLO1, an allogeneic dual chimeric antigen receptor (CAR) T-cell product candidate being developed for relapsed or refractory B-cell malignancies in partnership with F. Hoffmann-La Roche Ltd. The company is actively focused on opening clinical sites for a phase I study in adults with relapsed or refractory B-cell malignancies.

Shares of Poseida Therapeutics Inc. (NASDAQ:PSTX) closed Aug. 3 at $4.51, up $2.08, or 85%, as a result of the collaboration and licensing deal with Roche Holding AG that brings $110 million up front as well as the same amount in near-term milestone payments described by CEO Mark Gergen as “highly achievable,” and the arrangement could be worth as much as $6 billion if goals farther down the road are met.
