NCT04267887
This phase II trial studies how well the combination of apalutamide, abiraterone acetate, and prednisone after chemotherapy work in treating patients that have received no prior treatment (treatment naive) for high risk prostate cancer that is sensitive to androgen deprivation therapy (castration sensitive) and has spread to other parts of the body (metastatic). This study also aims to understand the inheritance of prostate cancer. If a gene or genes that cause prostate cancer can be found, the diagnosis and treatment of prostate cancer may be improved. Testosterone (a male hormone) can cause the growth of prostate cancer cells. Hormone therapy using apalutamide may fight prostate cancer by blocking the use of testosterone by the tumor cells. Antihormone therapy, such as abiraterone acetate, may lessen the amount of testosterone made by the body. Anti-inflammatory drugs such as prednisone lower the body's immune response and are used with other drugs in the treatment of some types of cancer. Apalutamide, abiraterone acetate, and prednisone after chemotherapy may work better in treating patients with castration sensitive prostate cancer.
NCT05053152
This phase II trial compares the usual treatment of radiation therapy alone to using the study drug, relugolix, plus the usual radiation therapy in patients with castration-sensitive prostate cancer that has spread to limited other parts of the body (oligometastatic). Relugolix is in a class of medications called gonadotropin-releasing hormone (GnRH) receptor antagonists. It works by decreasing the amount of testosterone (a male hormone) produced by the body. It may stop the growth of cancer cells that need testosterone to grow. Radiation therapy uses high-energy x rays or protons to kill tumor cells. The addition of relugolix to the radiation may reduce the chance of oligometastatic prostate cancer spreading further.
