Overview
This is a Phase 2, open-label, global, multi-arm study to evaluate efficacy and safety of relacorilant in combination with other treatments in patients with gynecological cancers.
Description
This study is designed with the goal to add additional arms as new treatments become available. All arms will follow an independent and parallel design.
For Arms A and B, study treatment will comprise 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 Cycle 1 relacorilant is only given on 2 consecutive days, starting on C1D1), in combination with nab-paclitaxel (80 mg/m\^2 intravenously \[IV\]) 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. Study treatment for Arm C will be similar to Arm A but does not include bevacizumab. Patients will receive treatment until they reach a protocol-defined event of progressive disease (PD), experience an unmanageable toxicity, or until other treatment discontinuation criteria are met.
