Testing Whether the Addition of Carboplatin Chemotherapy to Cabazitaxel Chemotherapy Will Improve Outcomes Compared to Cabazitaxel Alone in People With Castrate-Resistant Prostate Cancer That Has Spread Beyond the Prostate to Other Parts of the Body
Trial Parameters
Brief Summary
This phase III trial compares the effect of adding carboplatin to the standard of care chemotherapy drug cabazitaxel versus cabazitaxel alone in treating prostate cancer that keeps growing even when the amount of testosterone in the body is reduced to very low levels (castrate-resistant) and that has spread from where it first started (primary site) to other places in the body (metastatic). Carboplatin is in a class of medications known as platinum-containing compounds. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Chemotherapy drugs, such as cabazitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Prednisone is often given together with chemotherapy drugs. Prednisone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs and to help the chemotherapy work. Giving carboplatin with the standard of care chemotherapy drug cabazitaxel may be better at treating metastatic castrate-resistant prostate cancer.
Eligibility Criteria
Inclusion Criteria: * STEP 1 SCREENING REGISTRATION: NOTE: All participants must have biopsy tissue submitted to MD Anderson Cancer Center prior to randomization for alteration assessment. Participants must have determination of their AVPC-Molecular Pathologic Signature immunohistochemistry (MSIHC) status from central assessment by the MD Anderson Clinical Pathology Laboratory using Clinical Laboratory Improvement Act (CLIA) certified immunohistochemistry (IHC) assays for TP53, RB1 and PTEN.
