Engineered t cells take on Hard-to-Treat prostate cancer
NCT ID NCT07285694
First seen Jun 26, 2026 · Last updated Sep 04, 2026 · Updated 3 times
Summary
This study tests a new treatment called AB-3028, which uses a patient's own immune cells (T cells) that have been modified in a lab to better attack prostate cancer cells. It is for men with metastatic castration-resistant prostate cancer, a type that has stopped responding to hormone therapy. The trial will enroll 190 participants to check safety and find the best dose.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AB-3028 (engineered T cells)
- What this could lead to
- If successful, this could lead to a new treatment option for men with advanced prostate cancer that has stopped responding to standard therapies.
- What could go wrong
- This is an early-phase trial (Phase 1/2) with a small number of participants, so the treatment may not prove effective or safe. T cell therapies can cause serious side effects like cytokine release syndrome.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Key Inclusion Criteria: 1. At least 18 years of age at time of signing informed consent form. 2. Histologically confirmed adenocarcinoma of the prostate, meeting all of the following criteria: • Documented progressive metastatic castration-resistant prostate cancer (mCRPC) based on PCWG3 criteria. 3. Prior prostate cancer treatment with at least 1 novel androgen receptor pathway inhibitor (ARPI) therapy. • PSMA+ by PSMA PET. * Measurable disease by RECIST 1.1 criteria, or evaluable disease via measurable PSA (≥ 1 ng/mL) per PCWG3 criteria. 4. Adequate organ functions. Key Exclusion Criteria: 1. Any prior systemic therapy for CRPC within 14 days prior to scheduled protocol required leukapheresis. 2. Central nervous system (CNS) metastatic disease, leptomeningeal disease, or cord compression. 3. Unwillingness to participate in an extended safety monitoring period.
