Poseida Therapeutics Presents Preclinical Solid Tumor Data for P-PSMA-101, a CAR-T Therapy Predominantly Comprised of Stem Cell Memory T Cells, at the Prostate Cancer Foundation Annual Retreat

Poseida Therapeutics Inc. (“Poseida”), a San Diego-based clinical-stage company translating best-in-class gene therapy technologies into lifesaving cell therapies, today presented preclinical data on P-PSMA-101, the company’s PSMA-specific chimeric antigen receptor T cell (CAR-T) stem cell memory drug candidate for the treatment of prostate cancer, showing potent anti-tumor activity, a persistent and durable response, and no T-cell exhaustion observed. This preclinical study demonstrated that Poseida’s advanced CAR-T cell therapy could completely eliminate solid tumors in a previously incurable preclinical model of prostate cancer, and was selected for oral presentation today at the 24th Prostate Cancer Foundation Annual Retreat in Washington DC.
