Durvalumab and Olaparib for the Treatment of Prostate Cancer in Men Predicted to Have a High Neoantigen Load

Prostate Adenocarcinoma Clinical Trial

Official title:
Durvalumab (MEDI4736) and Olaparib (AZD2281) for Treatment of Biochemically Recurrent Prostate Cancer in Men Predicted to Have a High Neoantigen Load: A Multicenter Pilot Study

Clinical Trial Summary

This phase II trial studies how well durvalumab and olaparib work in treating prostate cancer in men predicted to have specific genetic mutations (a high neoantigen load). Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Giving durvalumab and olaparib may kill more tumor cells in patients with prostate cancer predicted to have a high neoantigen load.

Clinical Trial Description

OUTLINE: All patients receive durvalumab IV over 1 hour on day 1 of each cycle, total 6 cycles. Starting cycle 4, patients with CDK12 mutations and mismatch repair deficiency (MMRd)/microsatellite instability (MSI)-high will also receive olaparib orally (PO) twice daily (BID) on days 1- 28 of cycles 4-6. Patients with homologous recombination mutation will also receive olaparib PO BID on days 1-28 of cycles 1-6. Cycles repeat every 28 days for 6 cycles in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 2 weeks, and then every 12 weeks to complete 24 months (at 9, 12, 15, 18, 21 and 24 months). ;
