Study to Evaluate Relacorilant (CORT125134) in Combination With Nab-paclitaxel in Participants With Solid Tumors

The study consisted of two segments to evaluate alternative dosing schedules of relacorilant administered at escalating dose levels. Segment I was to evaluate a continuous-dosing regimen and Segment II was to evaluate an intermittent-dosing regimen. Enrollment in Segment I and Segment II were mutually exclusive, and the two segments enrolled participants concurrently. In Segment I continuous-dosing cohorts, participants received a single nab-paclitaxel lead-in infusion on Day 1 of Week -2 before Cycle 1, and oral relacorilant lead-in once-daily of Week -1 before Cycle 1. After the Data Review Committee review of data for 2 dose levels, the nab-paclitaxel lead-in was discontinued. The lead-in period was followed by oral relacorilant administered continuously once daily, in combination with nab-paclitaxel infusions on Days 1, 8, and 15 of each 28-day cycle. Segment 1 enrolled a total of 64 participants. In Segment II intermittent-dosing cohorts, participants received a single relacorilant lead-in dose on Day -1 before Cycle 1, followed by oral relacorilant, administered intermittently the day before, the day of, and the day after nab-paclitaxel infusions on Days 1, 8, and 15 of each 28-day cycle. Segment II enrolled a total of 21 participants.
