Archival tissue should represent invasive or metastatic urothelial cancer with a preference for metastatic tissue if available. Archival tissue should be identified at screening and shipped by C1D1. Subjects without adequate tissue may be considered on a case by case basis after discussion with the sponsor-investigator.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Olaparib Monotherapy; The starting dose of olaparib tablets will be dependent on the subject's calculated creatinine clearance (CrCl). Subjects with a CrCl of ≥ 40 mL/min will start at a dose of olaparib tablets of 300 mg twice a day. Subjects with a CrCl of > 30 to < 40 mL/min will start at a dose of olaparib tablets 200 mg twice a day.	Drug: Olaparib; 1 cycle = 28 days. Subject's with calculated creatinine clearance (CrCl) of ≥ 40 mL/min will start at a dose of olaparib tablets of 300 mg twice a day. Subjects with a CrCl of > 30 to < 40 mL/min will start at a dose of olaparib tablets 200 mg twice a day.; Other Names: Lynparza

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression-Free Survival (PFS)	Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST): Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Progressive Disease (PD) >= 20% increase in tumor burden relative to nadir or the appearance of one or more new lesions; Stable Disease (SD), not meet criteria for CR/PR/PD. PFS is defined as time from registration until disease progression met by RECIST 1.1 or death from any cause.	Time of treatment start until the criteria for disease progression or death. Up to a maximum of 17 months.

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Survival (OS)	Overall survival is defined as the time from treatment start until death or date of last contact.	Time of treatment start until death or date of last contact, up to a maximum of 23 months.
Adverse Events	Number of participants with treatment related adverse events are reported by CTCAEv4 term and grade.
