Abstract 615TiP
Background
A standard therapy for advanced high grade ovarian carcinoma (AHGOC) is an upfront complete surgery followed by adjuvant platinum-taxane chemotherapy adding maintenance targeted therapies. The most common maintenance strategies include bevacizumab and PARP inhibitors. Following the results of the PRIMA (Gonzales Martin, et al NEJM 2019) and PAOLA-1 (Ray-Coquard, et al NEJM 2019) studies, the question of the most efficient maintenance therapy for FIGO stage III patients remains uncertain considering PARPi alone or in combination with bev.
Trial design
NIRVANA-1 is an international randomized, open-label, phase II trial. 390 FIGO stage III patients with completely resected AHGOC, receive a first CP cycle and are randomized (1:1) to receive either 5 additional CP cycles followed by maintenance with nira or 5 cycles of CP + bev followed by maintenance with nira + bev. The total treatment duration will be 24 months for nira in both arms and 15 months for bev. Stratification factors include tumour BRCA status, FIGO stage (IIIA versus IIIB/IIIC) and use of hyperthermic intraperitoneal chemotherapy during surgery. The primary endpoint will be progression-free survival rate at 24 months. Secondary endpoints include safety, median PFS, PFS2, Time to First Subsequent Therapy (TFST), Time to Second Subsequent Therapy (TSST), OS, KELIM (K CA-125 ELIMination rate constant). The study is calibrated to detect a treatment effect corresponding to a 24-months PFS rate of 75% in the nira + bev arm and a 24-months PFS rate of 65% in the nira arm, translating in a HR of 0.67. The sample size is calculated to provide an 80% power to show a statistically significant PFS difference, accepting a 1-sided alpha risk of 10%, considering a minimal follow-up of 24 months, and dropout rate of 5%. The NIRVANA-1/GINECO-OV129b/ENGOT-ov63 trial is sponsored by the GINECO and currently recruiting in France, Spain, Italy, Belgium, Japan and Korea. The first patient was randomized in March 2022.
