PSCA-CAR T Cells in Treating Patients With PSCA+ Metastatic Castration Resistant Prostate Cancer
NCT03873805 · View on ClinicalTrials.gov ↗
Study 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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03873805
The ClinicalTrials.gov registry entry for NCT03873805 describes a study currently listed as active not recruiting. It is categorized as Phase 1, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 14 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is City of Hope Medical Center, which has 771 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 5 conditions, with Stage IVB Prostate Cancer AJCC v8 appearing as the primary indexed condition, and to 4 interventions — of which Cyclophosphamide is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03873805 reports 1 study location spanning 1 distinct geographic area — top geographies include California. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
