Active Comparator: Arm I (olaparib)
Patients receive olaparib PO BID in the absence of disease progression or unacceptable toxicity.
Experimental: Arm II (olaparib, tremelimumab)
Patients receive olaparib as in Arm I. Patients also receive tremelimumab IV over 60 minutes on day 1. Cycles of tremelimumab repeat every 4 weeks for 4 doses and then every 12 weeks for up to 2 years total in the absence of disease progression or unacceptable toxicity.
- Progression free survival (PFS) [ Time Frame: Duration of time from study entry to time of progression per Response Evaluation Criteria in Solid Tumors (RECIST) criteria or death due to any cause, whichever occurs first, assessed up to 5 years ]
- Dose-limiting toxicity (DLT) (Safety Lead-In) [ Time Frame: Up to 4 weeks ]Descriptive statistics will be used to summarize adverse events (AEs). The primary summary of AEs will present counts and percentages, regardless of whether the AE was attributed to any of the study agents.
- RECIST 1.1 response (Efficacy Lead-In) [ Time Frame: Up to 5 years ]A logistic model will be used to estimate the relative odds of responding (CR+PR) to olaparib + tremelimumab relative to olaparib after adjusting for BRCA mutation status and prior PARP inhibitor (PARPi) usage.
- Objective response [ Time Frame: Up to 5 years ]The objective response rate is the percentage of subjects with a best overall complete response (CR) or partial response (PR) among those with target lesions at the time of enrollment.
- Overall survival (OS) [ Time Frame: Time from enrollment and randomization to the date of death due to any cause, assessed up to 5 years ]Kaplan-Meier procedures will be used to estimate the cumulative distribution of survival times for each treatment in this population. A proportional hazards model stratified by BRCA status and prior PARPi treatment will be used to estimate the treatment hazard ratio and the corresponding confidence interval.
- Incidence of adverse events [ Time Frame: Up to 5 years ]Safety data will be summarized for all treated subjects. All adverse events, including severe adverse events (SAEs) and treatment-related adverse events, will be categorized and graded for severity according to National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0.

Submission of BRCA testing results (germline and/or somatic) is required for all patients.

Evidence of post-menopausal status or negative urinary or serum pregnancy test for pre-menopausal patients. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply:
- Women < 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
- Women >= 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses > 1 year ago, had chemotherapy-induced menopause with last menses > 1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
- Administration of study drugs (olaparib, tremelimumab) may have an adverse effect on pregnancy and poses a risk to the human fetus, including embryo-lethality.
