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.
