Targeted Inhibition of CYP11A1 in Prostate CancerIn this single-arm, multicenter, combined phase 1 and phase 2 study, patients with metastatic prostate adenocarcinoma with progression on prior androgen receptor pathway inhibitors and taxane-based chemotherapy were treated with ODM-208. A decrease in prostate-specific antigen levels of 50% or more occurred in 16/42 (38.1%) and 24/45 (53.3%) in phase 1 and 2 respectively. Responses mainly occurred in patients with androgen receptor mutations. Adrenal insufficiency was the dose-limiting toxicity.
