What the film says

Read the transcript

This trial is for adult men with metastatic castration-resistant prostate cancer, an inactivating ATM, CDK12 or CHEK2 mutation, and progression after an androgen-receptor signaling inhibitor. Symptoms must be absent or minimal.

The idea: test whether DNA-repair defects predict response to high-dose testosterone. Monthly injections under the skin accompany ongoing androgen deprivation. Researchers measure sustained PSA reductions, progression and side effects; benefit is uncertain.

This phase 2 study plans 51 patients. VA’s Robert Montgomery leads it; 16 US sites are recruiting, including Seattle.
