|Experimental: Study Arm||
Durvalumab will start 4 weeks after the first dose of olaparib (Cycle 2, Day 1) at 1500 mg intravenous (IV) every 4 weeks.
2 x 150 mg tablets taken in the morning and in the evening orally (2 X 300 mg daily)
Two intramuscular injections of 250 mg each on Cycle 1 Days 1 and 15, and then Day 1 of each subsequent 28-day cycle.
- Progression-free survival rate (PFSR) [ Time Frame: 24 weeks ]The progression-free survival rate at 24 weeks defined as the percentage of patients alive without disease progression at 24 weeks after inclusion. PFSR will be evaluated by local investigator using Response Evaluation Criteria in Solid Tumours version 1.1 (RECIST v1.1). The death of a patient for any cause within 24 weeks will be considered as failure
- The incidence of adverse events (Safety) [ Time Frame: 6 years ]Adverse events will be graded using NCI-CTCAE v5.0
- Overall Survival (OS) [ Time Frame: 6 years ]OS is defined as the interval between the date of inclusion and the date of death from any cause. A patient alive will be censored at the last date of follow-up
- Objective response rate (ORR) [ Time Frame: 3 years ]The ORR defined as the percent of patients with a complete response (CR) or a partial response (PR).
- Duration of response (DoR). [ Time Frame: 3 years ]The DoR defined as the duration between the time measurement criteria are first met for CR or PR until the first date that recurrent disease is objectively documented
- Progression-free survival (PFS) [ Time Frame: 6 years ]PFS defined as the interval between the date of inclusion and the date of progression or death. A patient alive and without progression will be censored at the last date of follow-up.
