Olaparib in Treating Participants with Metastatic or Unresectable Urothelial Cancer with DNA Damage Response Gene Alterations
This phase II trial studies how well olaparib works in treating participants with urothelial cancer with deoxyribonucleic acid (DNA) damage response gene alterations that has spread to other places in the body or cannot be removed by surgery. Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Trial Objectives and Outline
I. Estimate the objective response rate (per Response Evaluation Criteria in Solid Tumors [RECIST] 1.1) or MD Anderson criteria for bone only metastases to treatment with olaparib in subjects with metastatic urothelial cancer harboring somatic DNA damage response (DDR) alterations.
I. Describe the safety of olaparib in subjects with DDR mutant metastatic urothelial cancer.
II. Describe the progression-free survival of subjects with DDR mutant metastatic urothelial cancer treated with olaparib.
III. Describe the overall survival of subjects with DDR mutant metastatic urothelial cancer treated with olaparib.
I. Explore the relationship between specific genomic alterations with response to olaparib.
II. Explore the relationship between prior platinum-based chemotherapy treatment (response, duration of treatment, and time since treatment) with response to olaparib.
III. Explore the relationship between tumor mutational profile, circulating DNA mutational profile, and response to olaparib.
IV. Determine the feasibility of establishing patient-derived xenografts from circulating tumor cells collected from enrolled subjects at baseline and progression to better explore mechanisms of response and resistance.
Participants receive olaparib orally (PO) twice daily (BID) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, participants are followed up at 30 days, then every 3 months for up to 2 years.
