Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study was to assess the safety of the combination of relacorilant (CORT125134), a novel glucocorticoid receptor (GR) antagonist, and nab- paclitaxel in participants with solid tumors and to determine the preliminary efficacy of the combination of relacorilant and nab-paclitaxel. The structure for the study was a single arm, non-randomized, open- label, multicenter trial with no control group.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria
