Poseida initiates P-BCMA-ALLO1 Phase 1b clinical trial in patients with multiple myeloma, generating $20 million payment from Roche
SAN DIEGO, Sept. 5, 2024 -- Poseida Therapeutics, Inc. (Nasdaq: PSTX), a clinical-stage allogeneic cell therapy and genetic medicines company advancing differentiated non-viral treatments for patients with cancer and rare diseases, announced today that new clinical data from an ongoing Phase 1 study of P-BCMA-ALLO1 in patients with relapsed/refractory multiple myeloma will be presented in an oral session at the 21st International Myeloma Society (IMS) Annual Meeting, which is being held in Rio de Janeiro from September 25-28, 2024. The Company is developing P-BCMA-ALLO1, an investigational off-the-shelf allogeneic CAR-T cell therapy enriched for stem cell memory T cells (TSCM), in partnership with Roche for the treatment of relapsed/refractory multiple myeloma.
"Despite therapeutic advances, multiple myeloma remains an incurable hematologic cancer and relapses are common with BCMA-targeting immunotherapies, such as bispecific T-cell engagers and autologous CAR-T therapies. As a result, patient-focused, off-the-shelf therapies are needed that can provide clinical benefit to patients with relapsed or refractory disease," said Syed Rizvi, M.D., Chief Medical Officer of Poseida Therapeutics. "We look forward to presenting the latest data from our ongoing Phase 1 study of P-BCMA-ALLO1 and its potential as an 'off-the-shelf' therapy for patients at IMS. We are also pleased to announce the initiation of the Phase 1b portion of the study, which will allow us to further explore the promise of this program."
