ClinConnect Summary
This clinical trial is studying a new treatment approach for men with metastatic castration-resistant prostate cancer (CRPC) that has not responded to standard therapies. The treatment involves using modified immune cells, known as PSMA CAR-T cells, which are designed to target and attack the cancer cells. The trial will take place at a single center and is open to enrolling between 7 to 18 participants who meet specific eligibility criteria.
To qualify for this trial, participants must be male, aged 18 to 75, with a confirmed diagnosis of metastatic CRPC that has continued to progress despite other treatments. They should also have a good understanding of the study and be able to provide informed consent. Participants can expect to receive close monitoring during the trial to assess the safety and effectiveness of this new treatment. It’s important to note that those who have previously received CAR-T therapy or certain other treatments targeting PSMA will not be eligible to join. Overall, this study aims to explore a promising option for patients facing challenging cancer cases.
