City of Hope opens Phase 2 trial to test if mushroom tablets could slow prostate cancer

(City of Hope) City of Hope, a cancer research and treatment center, is now recruiting patients for a Phase 2 clinical trial to investigate whether pills containing white button mushroom extract could regulate the immune system, affecting prostate-specific antigen (PSA) levels to either remain stable or decline. Heightened levels of PSA in men may indicate the existence of prostate tumors. The fungus appears to block the activity of dihydrotestosterone (DHT), a strong form of the male hormone.
