Date and Time: Thursday, December 8, 2022 at 12:30-1:15 PM CET


P-MUC1C-ALLO1 is an allogeneic CAR-T product candidate in Phase 1 development for multiple solid tumor indications. Poseida believes P-MUC1C-ALLO1 has the potential to treat a wide range of solid tumors derived from epithelial cells, such as breast, colorectal, lung, ovarian, pancreatic and renal carcinomas, as well as other cancers expressing a cancer-specific form of the Mucin 1 protein, or MUC1-C. P-MUC1C-ALLO1 is designed to be fully allogeneic, with genetic edits to eliminate or reduce both host-vs-graft and graft-vs-host alloreactivity. Poseida has demonstrated the elimination of tumor cells to undetectable levels in preclinical models of both breast and ovarian cancer. Additional information about the Phase 1 study is available at using identifier: NCT05239143.


P-BCMA-ALLO1 is an allogeneic CAR-T product candidate, partnered with Roche, targeting B-cell maturation antigen (BCMA) for the treatment of relapsed/refractory multiple myeloma in Phase 1 development. In vitro and in vivo P-BCMA-ALLO1 preclinical studies, showed effective, targeted cancer cell killing and cytokine secretion, with similar or superior anti-tumor efficacy compared to an autologous CAR-T therapy. Additional information about the Phase 1 study is available at using identifier: NCT04960579.
