Overview
This is a Phase 2, single-arm study to evaluate the safety and efficacy of relacorilant in combination with nab-paclitaxel and gemcitabine in patients with previously untreated metastatic pancreatic adenocarcinoma (PDAC).
Description
Study treatment will be comprised of relacorilant, combined with nab-paclitaxel and gemcitabine. Each patient will receive relacorilant 150 mg administered orally under fed conditions, once daily for 3 consecutive days on the day before (excluding Cycle 1 Day -1), the day of, and the day after nab-paclitaxel (100 mg/m\^2) and gemcitabine (1000 mg/m\^2) infusions. Nab-paclitaxel and gemcitabine will be administered on Days 1, 8, and 15 of each 28-day cycle. Patients will receive study treatment until they reach progressive disease (PD), experience unmanageable toxicity, or until other discontinuation criteria are met.
