Detailed Description

This study will include 2 parts. In Part 1 (dose finding), approximately 6 patients will be enrolled to individual dose-finding cohorts. Cohorts will receive various dose concentrations of relacorilant, nab-paclitaxel, and gemcitabine at various dosing schedules. In all dose-finding cohorts, relacorilant will be administered orally under fed conditions, once daily for 3 days on the day before (excluding Cycle 1 Day -1), the day of, and the day after nab-paclitaxel and gemcitabine. Enrollment will be paused after each cohort has been filled until the safety review committee (SRC) provides recommendations. If maximum tolerated dose (MTD) criteria are not met in a cohort, then either a dose-finding cohort at a more intense dose and/or schedule may be enrolled, or a dose and schedule at/below the MTD may be selected as the optimal dose and schedule, and Part 2 may be initiated. If MTD criteria are met, then a dose-finding cohort at a less intense dose and/or schedule may be enrolled, or dose-finding may end without proceeding to Part 2.

In Part 2 (expansion), each patient will receive the optimal dose and schedule of relacorilant, nab-paclitaxel, and gemcitabine as identified in Part 1. Analysis of Part 2 will include data for patients from Part 1 who were enrolled in the optimal dose and schedule used in Part 2.
