A Phase I Study to Evaluate PSCA-Targeting Chimeric Antigen Receptor (CAR)-T Cells for Patients With PSCA+ Metastatic Castration Resistant Prostate Cancer

City of Hope Medical Center·interventional·Posted Mar 13, 2019·Updated Jun 2, 2026

In Brief

A Phase 1 clinical trial evaluating Autologous Anti-PSCA-CAR-4-1BB/TCRzeta-CD19t-expressing T-lymphocytes, Cyclophosphamide, and 2 other interventions for Castration-Resistant Prostate Carcinoma and 4 related conditions. Active but no longer recruiting, targeting 14 participants across 1 site.

Detailed Summary

This phase I trial studies side effects and best dose of PSCA-chimeric antigen receptor (CAR) T cells in treating patients with prostate stem cell antigen positive (PSCA+) castration resistant prostate cancer that has spread to other places in the body (metastatic). PSCA-CAR T cells are immune cells that have been engineered in the laboratory to kill tumor cells. This is done by using a virus to insert a piece of deoxyribonucleic acid (DNA) into the immune cells that allows them to recognize prostate tumor cells. It is not yet known how well PSCA-CAR T cells works in killing tumor cells in patients with metastatic castration resistant prostate cancer.

Arms & Interventions

Treatment (PSCA CAR T cells)experimental

Patients may receive lymphodepleting regimen (either standard or modified) including fludarabine IV on days -5 to -3 and cyclophosphamide IV on days -5 to -3 or on days -4 and/or -3. The study PI and the protocol team will choose a chemotherapy regimen, for lymphodepletion prior to the PSCA-CAR T cell infusion (with the exception of cohorts 1 and -1 which will not receive lymphodepletion), based on the research participant's disease type and prior therapies. Patients then receive autologous anti-PSCA-CAR-4-1BB/TCRzeta-CD19t-expressing T lymphocytes IV over 10-15 minutes at day 0.
