Patients must have normal organ and bone marrow function measured within 7 days prior to administration of study treatment as defined below: i. Hemoglobin >/= 10.0 g/dL dL (unless due to bone marrow infiltration by tumor, in which case hemoglobin >/=8gdL is allowed). Patient may have blood transfusions prior to study enrollment. ii.

Summary

This trial is studying olaparib to see how well it works in combination with cabazitaxel, carboplatin, and prednisone in treating patients with aggressive variant prostate cancer.

Who is the study for?
This trial is for men over 18 with aggressive variant prostate cancer (AVPC) that's resistant to castration and has spread. They must have normal organ function, be able to swallow pills, consent to genetic research, and use birth control if needed. Excluded are those with certain medical conditions or who've had specific treatments for CRPC.
What is being tested?
The study tests if olaparib can control AVPC after treatment with cabazitaxel, carboplatin, and prednisone. It's an investigational study of these drugs' combination; up to 96 participants at MD Anderson will receive this regimen following informed consent.
What are the potential side effects?
Possible side effects include allergic reactions to the medications used, gastrointestinal issues due to oral medication intake, potential liver problems from drug interactions or pre-existing conditions, blood disorders like myelodysplastic syndrome/acute myeloid leukemia.
