A Phase 1b Study Evaluating Combinations With PSCA-Targeting Chimeric Antigen Receptor (CAR)-T Cells for Patients With PSCA+ Metastatic Castration-Resistant Prostate Cancer

City of Hope Medical Center·interventional·Posted Apr 10, 2023·Updated Nov 19, 2025

In Brief

A Phase 1 clinical trial evaluating Autologous Anti-PSCA-CAR-4-1BB/TCRzeta-CD19t-expressing T-lymphocytes, Biopsy, and 6 other interventions for Castration-Resistant Prostate Carcinoma and 2 related conditions. Currently recruiting, targeting 21 participants across 1 site.

Detailed Summary

This phase Ib trial tests the safety, side effects, and best dose of autologous anti-prostate stem cell antigen (PSCA)-chimeric antigen receptor (CAR)-4-1BB/TCRzeta-CD19t-expressing T-lymphocytes (PSCA-CAR T cells), plus or minus radiation, in treating patients with castration-resistant prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Castration-resistant prostate cancer continues to grow and spread despite the surgical removal of the testes or medical intervention to block androgen production. CAR T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. Giving PSCA-targeting CAR T-cells, with or without radiation, may kill more tumor cells in men with castration-resistant prostate cancer.
