BrUOG 337: Olaparib Prior to Radical Prostatectomy For Patients With Locally Advanced Prostate Cancer and Defects in DNA Repair Genes

NCT03432897

Description:

This study will evaluate approximately 3 months of treatment with the drug olaparib in patients with prostate cancer. A capsule formulation of olaparib (tradename Lynparza™) is approved by the United States Food and Drug Administration (FDA) for the treatment of women with advanced BRCA-mutated ovarian cancer. Olaparib is an investigational drug in prostate cancer. A tablet formulation of olaparib is being tested in this study. It is a new formulation which is more convenient for patients than the approved capsule formulation because fewer tablets of olaparib need to be taken daily than with capsules. The purpose of the study is to evaluate whether olaparib can reduce prostate cancer with defects in DNA repair genes when olaparib is given for approximately 3 months before surgery.
