Brief Summary

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

This is a Phase 3, randomized, double-blind, placebo-controlled study to assess the efficacy, and safety of relacorilant to treat hypercortisolism in patients with cortisol-secreting adrenal adenoma or hyperplasia associated with diabetes mellitus/ impaired glucose tolerance (DM/IGT) and/or uncontrolled systolic hypertension (HTN).

Detailed Description

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

The primary outcome measures of the study are 1) to assess the efficacy of relacorilant based on blood pressure control at Week 22 compared with placebo, and 2) to assess the safety of relacorilant based on adverse events. Patients will be randomized in a 1:1 ratio to treatment with relacorilant (active drug) or placebo. Patients will receive relacorilant or placebo for 22 weeks. Patients who complete the study may also be eligible to roll over into an extension study.
