Description

Summary

An open-label, multi-center, single and cyclic ascending dose study of P-PSMA-101 autologous CAR-T cells in patients with mCRPC and SGC.

Official Title

A Phase 1 Dose Escalation and Expanded Cohort Study of P-PSMA-101 in Subjects With Metastatic Castration-Resistant Prostate Cancer (mCRPC) and Advanced Salivary Gland Cancers (SGC)

Details

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-PSMA-101 to determine a Recommended Phase 2 Dose (RP2D). Additional participants will be treated with P-PSMA-101 at the determined RP2D.

Following consent, enrolled participants will undergo a leukapheresis procedure to obtain peripheral blood mononuclear cells (PBMCs) which will be sent to a manufacturing site to produce P-PSMA-101 CAR-T cells. The cells will then be returned to the investigational site and administered after a lymphodepleting chemotherapy regimen. Rimiducid may be administered as indicated.

Lead Scientist at University of California Health

  • David Oh (ucsf)
    I am a physician-scientist focused on developing novel immunotherapies with enhanced activity and reduced toxicity, for patients with solid cancers. Clinically, I see patients in the Cancer Immunotherapy Program where I lead numerous early phase trials, with a particular focus on adoptive cell therapies for solid tumors (CAR-T and TCR).
