About P-PSMA-101
P-PSMA-101 is an autologous CAR-T therapeutic candidate in metastatic castration-resistant prostate cancer (mCRPC). It is designed to target prostate-specific membrane antigen (PSMA), which is expressed on mCRPC cells. It was developed using Poseida’s proprietary piggyBac DNA Modification System, which produces product candidates with a high percentage of stem cell memory T (TSCM) cells. A Phase 1 trial of P-PSMA-101 in mCRPC was initiated in May 2020.
