Roche has announced that it has entered into a definitive merger agreement to acquire Poseida Therapeutics, a public clinical-stage biopharmaceutical company pioneering donor-derived CAR-T cell therapies.
Based in San Diego, California, Poseida’s R&D portfolio includes pre-clinical and clinical-stage off-the-shelf (also referred to as allogeneic) CAR-T therapies across several therapeutic areas including haematological malignancies, solid tumours, and autoimmune disease, as well as manufacturing capabilities and technology platforms.
The acquisition builds on the existing partnership between Roche and Poseida following the collaboration and licence agreement established in 2022, which focuses on developing off-the-shelf CAR-T cell therapies to address medical needs of patients with haematological malignancies.
The joint vision of Poseida, Roche and Genentech, a member of the Roche Group, is to deliver the next generation of off-the-shelf CAR-T cell therapies with increased potency and favourable safety at a scale that can potentially reach more patients and enable broad commercial use.
“This exciting acquisition will allow us to drive further progress in allogeneic cell therapy while leveraging the successful existing partnership with Poseida,” said Levi Garraway, Head of Product Development and Chief Medical Officer at Roche. “We are very encouraged by the early clinical data, and this acquisition builds on our joint progress to catalyse the development of potentially first and best-in-class cell therapies in oncology, immunology and neurology.”
Poseida Therapeutics is a clinical-stage biopharmaceutical company advancing differentiated allogeneic cell therapies and genetic medicines with the capacity to cure. The company's pipeline includes investigational allogeneic CAR-T cell therapies for haematologic cancers, autoimmune diseases, and solid tumours, as well as investigational in vivo genetic medicines that address patient populations with high unmet medical need. Poseida’s approach is based on its proprietary genetic editing platforms, including its non-viral transposon-based DNA delivery system, Cas-CLOVER™Site-Specific Gene Editing System, Booster Molecule and nanoparticle gene delivery technologies, as well as in-house GMP cell therapy manufacturing. The Company has formed strategic collaborations with Roche and Astellas to unlock the promise of cell therapies for cancer patients.
The total deal value, including certain milestone payments, is worth up to US $1.5 billion. The transaction is expected to close in the first quarter of 2025, subject to customary closing conditions.
