Carboplatin or Olaparib for BRcA Deficient Prostate Cancer

An Open-label, Multicenter Phase II Study to Compare the Efficacy of Carboplatin as First-line Followed by Second-line Olaparib Versus Olaparib as First-line Followed by Second-line Carboplatin in the Treatment of Patients With Castration Resistant Prostate Cancer Containing Homologous Recombination Deficiency

Conditions

Summary

This is an unblinded, randomized clinical study comparing the efficacy of DNA damaging chemotherapy using carboplatin, to standard of care therapy for patients who have metastatic castrate resistant prostate cancer. This trial will use olaparib or carboplatin as initial therapy with crossover to the alternate or second-line drug after first progression for patients with tumors containing BARD1, BRCA1, BRCA2, BRIP1, CHEK1, FANCL, PALB2, RAD51B, RAD51C, RAD51D, or RAD54L inactivating mutations. Participants are randomized (1:1) and receive either carboplatin (AUC 5, IV) every 21 days, first or olaparib taken orally (300 mg), twice daily in 28 day cycles, until intolerance, complete response, or progression by Prostate Cancer Working Group 3 (PCWG3) criteria. Participants then crossover from the first-line therapy to the second-line therapy with the opposite study medication and receive treatment to intolerance or progression (whichever is first). Enrolled participants will be allowed to crossover to second line therapy if they continue to meet initial eligibility criteria, and at least three weeks have elapsed since last administration of either carboplatin or olaparib. Throughout the study, safety and tolerability will be assessed. Progression will be evaluated with bone scan, CT of the abdomen/pelvis, or MRI and PSA as per PCWG3 criteria.

Plain Language Summary

Simplified for easier understanding

This trial compares two treatments for men with prostate cancer that has a specific DNA repair defect (BRCA gene mutation): standard carboplatin chemotherapy versus olaparib, a targeted drug that specifically attacks cancer cells with BRCA mutations. The goal is to find which works better for this group of patients. **You may be eligible if...** - You have prostate cancer that has spread (metastatic) and is no longer responding to hormone therapy - Your cancer has a BRCA1 or BRCA2 gene mutation (confirmed by testing) - You have not received certain prior treatments (specific restrictions apply) - You are in adequate general health **You may NOT be eligible if...** - Your cancer does not have a BRCA mutation - You have received prior treatment with PARP inhibitors or certain platinum chemotherapy - You have severe other medical conditions - You are unable to swallow pills (for the olaparib arm) Talk to your doctor to see if this trial is right for you.
