Overview
This open-label, dose-finding, and proof of concept study will evaluate the safety, tolerability, maximum-tolerated dose (MTD) and/or optimal dose of nenocorilant when administered in combination with nivolumab in patients with advanced solid malignancies.
Description
This is a Phase 1b/2 study that consists of 2 parts.
In the dose-finding Phase 1b part, researchers will evaluate escalating dose levels of nenocorilant (given with a fixed dose and schedule of nivolumab) in patients with advanced solid malignancies. All patients will be treated with the combination of nenocorilant plus nivolumab in 28-day cycles. Nenocorilant will be administered orally once daily using a continuous dosing schedule, under fed conditions. Nivolumab will be initially given at 240 mg administered intravenously (IV) once every 2 weeks. After 3 months of treatment, patients may choose to switch to a fixed dosing regimen of 480 mg IV once every 4 weeks if they tolerate the combination regimen of nenocorilant plus nivolumab.
The proof-of-concept Phase 2 part of this study is optional and may be added to further evaluate combination treatment in patients with advanced solid malignancies.
