Summary

The purpose of this study is to evaluate the safety and activity of BPX-601 CAR-T cells
in participants with previously treated advanced solid tumors (prostate) expressing high
levels of prostate stem cell antigen (PSCA). Participants' T cells are modified to
recognize and target the PSCA tumor marker on cancer cells.

Objectives

The goal of this study is to characterize the feasibility, safety, and clinical activity
of PSCA-specific CAR-T cells, BPX-601, administered with rimiducid to subjects with
previously treated, PSCA-positive advanced solid tumors (prostate). BPX-601 CAR-T cells
are genetically engineered to express a chimeric antigen receptor (CAR) to target the
PSCA antigen and a rimiducid-inducible signaling domain which functions as a molecular
"go-switch" to enhance activation and proliferation.

Phase 1: Cell dose escalation to identify the maximum dose of BPX-601 administered with
single or repeat doses of rimiducid.

Phase 2: Indication-specific dose expansion to assess the safety, pharmacodynamics
(including BPX-601 persistence), and clinical activity at the recommended dose identified
in Phase 1 in various PSCA-expressing solid tumors.

Eligibility

  1. Metastatic castration-resistant prostate cancer (mCRPC), with progressive disease per PCWG3 criteria during or following the direct prior line of therapy.
  2. Measurable disease per RECIST v1.1 at baseline; subjects with mCRPC with bone only metastases must have measurable PSA.
  3. Age =18 years.
  4. Life expectancy > 12 weeks.
  5. ECOG 0-1
  6. Adequate organ function.
**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments.
