Study Summary

This phase II trial studies how well olaparib works in treating participants with prostate cancer that has not spread to other parts of the body (localized). Olaparib may stop the growth of tumor cells by interfering with the activity of a substance called PARP, which is inside cells. Giving olaparib before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

Primary Outcome

Percent of patients who achieve a pCR at the time of prostatectomy, after 12 weeks of neoadjuvant therapy with olaparib. PCR is defined as the absence of morphologically identifiable carcinoma in the prostatectomy specimen. Assessment will be based on the recommendations of the International Society of Urological Pathology (ISUP).

Interventions
