Boosting PSMA on prostate cancer cells to help PSMA-targeted treatments work better

Augmenting PSMA expression to enhance PSMA directed therapeutic efficacy

['FUNDING_R37'] · FRED HUTCHINSON CANCER CENTER · NIH-11263635

Researchers will give drugs that raise PSMA on prostate cancer cells and combine that with PSMA-targeted therapy to try to help men with advanced metastatic prostate cancer respond better.

What this research studies

If you join, the team would use laboratory and patient-tissue research to find drugs that increase PSMA levels on prostate cancer cells. They plan to test those drugs in preclinical models and use human tumor samples (including data from rapid autopsy programs) to understand why some cancers have low PSMA. The goal is to give a PSMA-boosting drug before or with an approved PSMA-directed treatment like 177Lu-PSMA-617 so the therapy can reach and kill more tumor cells. The program combines lab experiments with work that could lead to trials offering this combination to patients.

Who could benefit from this research

Good fit: Ideal candidates are men with metastatic castration-resistant prostate cancer who are being considered for PSMA-directed therapy, especially if their tumors show low or uneven PSMA levels.

Not a fit: Men whose tumors completely lack PSMA expression, who are not eligible for PSMA-directed therapy, or who cannot tolerate additional drugs may not benefit.

Why it matters

Potential benefit: This could make PSMA-targeted treatments work for more men and improve tumor control or extend time without progression.

How similar studies have performed: PSMA-targeted radioligand therapy (177Lu-PSMA-617) is FDA-approved and helps many patients, but about half do not respond and early lab and clinical data suggest raising PSMA could improve responses though the approach is still under study.
