Updated on 7 February 2023


This is a Phase 3, double-blind, placebo-controlled, randomized-withdrawal study to assess the efficacy, safety and pharmacokinetics (PK) of relacorilant in patients with endogenous Cushing syndrome and concurrent type 2 diabetes mellitus/impaired glucose tolerance and/or uncontrolled hypertension


This Phase 3 study involves two phases, an open-label (OL) phase and a randomized-withdrawal (RW) phase. Patients will dose-escalate in 100 mg increments to a target dose of 400 mg orally once daily during the open-label phase. Patients will remain on open-label treatment until week 22 at which time they will be evaluated for the randomized-withdrawal phase based on pre-defined hyperglycemia and hypertension response criteria. Eligible patients will then be randomized to receive either relacorilant or placebo at a 1:1 ratio for 12 weeks. Patients who do not meet the criteria for randomization will end treatment and may be eligible to roll over into an extension safety study. Patients who complete the randomized-withdrawal phase of the study may also be eligible to roll over into an extension study.
