About P-BCMA-ALLO1
P-BCMA-ALLO1 is an allogeneic CAR-T product candidate licensed to Roche targeting B-cell maturation antigen (BCMA) for the treatment of relapsed/refractory multiple myeloma in Phase 1 development. This allogeneic program includes a VH-based binder that targets BCMA and has shown early evidence of encouraging safety and efficacy. Additional information about the Phase 1 study is available at www.clinicaltrials.gov using identifier: NCT04960579.
About P-FVIII-101
P-FVIII-101 is a liver-directed gene therapy partnered combining Poseida’s piggyBac platform and nanoparticle delivery technologies for the in vivo treatment of Hemophilia A. Hemophilia A is a bleeding disorder caused by a deficiency in Factor VIII production with a high unmet need. P-FVIII-101 utilizes the piggyBac gene integration system delivered via lipid nanoparticle, which has demonstrated stable and sustained Factor VIII expression in animal models.
