Therapies targeting DNA repair in advanced prostate cancer

Project 4: Clinical Development of Therapeutic Strategies Targeting Damage Repair

NIH-funded research Fred Hutchinson Cancer Center · NIH-11181535

This effort combines DNA-damaging treatments with high-dose testosterone to help men whose prostate cancer no longer responds to standard hormone therapy.

What this research studies

If you join, researchers may give high-dose (supraphysiological) testosterone alongside treatments that damage cancer DNA, such as certain chemotherapies, PARP inhibitors, or radiation. The plan includes a Phase 2 clinical trial for men with metastatic castration-resistant prostate cancer (mCRPC). Doctors may test tumor samples for defects in DNA repair genes to identify who is most likely to benefit. The approach aims to use how androgen signaling interacts with DNA repair to make cancer cells more vulnerable to treatment.

Who could benefit from this research

Good fit: Ideal candidates are men with metastatic castration-resistant prostate cancer, particularly those whose tumors show defects in DNA repair pathways.

Not a fit: Patients with early-stage prostate cancer, those who cannot tolerate genotoxic therapies, or whose tumors lack DNA-repair defects may not receive benefit from this approach.

Why it matters

Potential benefit: If successful, this approach could make resistant prostate cancers respond again and lengthen the time before the disease progresses.

How similar studies have performed: Previous studies show DNA-repair defects can make prostate cancers sensitive to platinum chemotherapy and PARP inhibitors, but combining these with high-dose androgen therapy is a newer strategy under clinical testing.
