Detailed Description
This is an open label, multi-center Phase 1 study that will follow a 3 + 3 design of dose-escalating cohorts of single and multiple doses of P-MUC1C-ALLO1 to determine a Recommended Phase 2 Dose (RP2D). P-MUC1C-ALLO1 is an allogeneic chimeric antigen receptor (CAR) T cell therapy designed to target cancer cells expressing Mucin1 cell surface associated C-Terminal (MUC1-C) antigen. Additional participants will be treated with P-MUC1C-ALLO1 at the determined RP2D. Following enrollment, subjects will be treated with P-MUC1C-ALLO1 and will undergo serial measurements of safety, tolerability and response. Rimiducid may be administered as indicated.
