Phase 2RecruitingSWOG Cancer Research NetworkNCT05806515Data as of May 2026

Treatment: CarboplatinThis phase II trial tests how well carboplatin before surgery works in treating patients with high-risk prostate cancer and an inherited BRCA1 or BRCA2 gene mutation. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping, or slowing the growth of tumor cells. Giving carboplatin before surgery may shrink tumors in patients with high-risk prostate cancer with BRCA1 and BRCA2 gene mutations.
