Relacorilant in Combination With Nab-paclitaxel and Bevacizumab in Advanced, Epithelial Ovarian, Primary Peritoneal, or Fallopian-Tube Cancer

This is a Phase 2, single-arm, open-label study to evaluate efficacy and safety of intermittent dosing of relacorilant in combination with nab-paclitaxel and bevacizumab in patients with ovarian cancer.

Study treatment will be comprised of relacorilant, combined with nab-paclitaxel, and bevacizumab and will begin on Cycle 1 Day 1 (C1D1). Each patient will receive relacorilant 150 mg administered orally under fed conditions, once daily for 3 consecutive days on the day before, the day of, and the day after nab-paclitaxel infusion, in combination with nab-paclitaxel (80 mg/m\^2 intravenous \[IV\]) administered on Days 1, 8, and 15 of each 28-day cycle. Bevacizumab (10 mg/kg IV once every 2 weeks \[Q2W\]) will be administered on Days 1 and 15 of each 28-day cycle. Patients will receive study treatment until they reach progressive disease, experience unmanageable toxicity, or until other discontinuation criteria are met. Patients will be monitored for treatment efficacy, safety, and tolerability.
