About this study

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.

You may qualify if…

✓ 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. In addition, while not mandated, CLIA certified next generation sequencing (NGS) of tumor deoxyribonucleic acid (DNA) and/or circulating tumor derived DNA (ctDNA) assessment of AVPC-MS marker status will be collected from participants for whom it is available
✓ STEP 1 SCREENING REGISTRATION: Participants must have a histologically confirmed diagnosis of prostate cancer at the time of step 1 registration
✓ STEP 1 SCREENING REGISTRATION: Participants must have castrate-resistant prostate cancer and metastatic disease by bone scan and/or CT/MRI (i.e., soft tissue, visceral, lymph node)
✓ STEP 1 SCREENING REGISTRATION: Participants may have received any prior therapy, but one must be docetaxel or contain docetaxel in either the castrate-sensitive and/or castrate resistant disease state
✓ STEP 1 SCREENING REGISTRATION: Participants must be ≥ 18 years of age at the time of step 1 screening registration
✓ STEP 1 SCREENING REGISTRATION: Participants must have solid tumor biopsy material (formalin-fixed paraffin-embedded (FFPE) tissue blocks and/or 10 cut slides on four-micron thick unstained positive charged slides of FFPE tissue) available for submission for alterations in TP53, RB1 and PTEN by IHC using CLIA certified assays in the MD Anderson Clinical Pathology Laboratory. This specimen is required for central assessment of the AVPC-MSIHC regardless of whether the site has already locally evaluated the AVPC-MS status
✓ STEP 1 SCREENING REGISTRATION: Tumor samples submitted for analysis must have been collected within 12 months prior to step 1 screening registration. Samples from metastatic lesions collected in the castrate-resistant disease state are preferable but not mandatory. Samples obtained during the hormone-naive disease state are acceptable if collected within 12 months of step 1 screening registration. If more than one tumor sample exists, the sample obtained closest to the date of registration should be submitted to MDACC for analysis
✓ NOTE: Sites will receive an email from Southwest Oncology Group (SWOG) Statistics and Data Management Center containing participant results of Aggressive Variant Prostate Cancer Molecular Signature (AVPC-MS) assessment within 5-12 business days after tissue submission to MD Anderson Clinical Pathology Laboratory. The participant's AVPC-MS signature result (positive or negative) is required BEFORE randomization on to step 2. If sites receive a non-evaluable AVPC-MS signature result, SWOG Statistics and Data Management Center will provide instructions for resubmission
