Platinum and Taxane Chemo in Met Castration Resistant Prostate Cancer Patients With Alterations in DNA Damage Response Genes
Is NCT06439225 recruiting? Yes, currently enrolling (Sep 2026). This Phase 3 trial studies multiple treatments including Docetaxel and Carboplatin for metastatic castration-resistant prostate cancer.
Treatment: Docetaxel · Carboplatin — The usual approach for most patients who are not in a study is treatment with docetaxel. This study is being done to answer the following question: Can the chance of prostate cancer growing or spreading be lowered by adding a drug to the usual approach? This study is being done to find out if this approach is better or worse than the usual approach for prostate cancer. The usual approach is defined as the care most people get for prostate cancer.
