Key clinical point: Nivolumab plus docetaxel shows good response in patients with chemotherapy-naive metastatic castration-resistant prostate cancer (mCRPC).
Major finding: The confirmed overall response rate was 40%. The median time to objective response was 2 months, and the median response duration was 7 months. The confirmed prostate-specific antigen (PSA) 50-response rate (50% or higher decline in PSA) was 46.9%.
Study details: A phase 2, nonrandomized CheckMate 9KD trial of 84 patients with chemotherapy-naive mCRPC who received androgen deprivation therapy and ≤2 prior novel hormonal therapies and were treated with nivolumab and docetaxel with prednisone followed by nivolumab maintenance for ≤2 years.
