Measure
Rucaparib in Combination With Nivolumab
One treatment cycle will consist of 28 days. Patients will receive rucaparib at 600 mg, orally, twice daily, continuously for 28 days. They will receive 480mg of nivolumab intravenously on day 1 of every four-week cycle. This is the recommended phase II dose of the combination therapy. Re-staging scans will be performed every 8 weeks. Treatment will be repeated until the patient develops progressive disease or unacceptable toxicity or for a maximum duration of 26 cycles as long as patients are receiving benefit from treatment, have not had disease progression, met any criteria for study withdrawal and are tolerating therapy.

SECONDARY outcome

Timeframe: at 24 weeks

PFS is defined as the period from start of study treatment until recurrent or progressive of disease (POD) is objectively documented (taking as reference for progressive disease the smallest measurement recorded on study), death, or date of last study visit involving assessment of disease status.
