Treatment for adrenal insufficiency in patients with Cushing syndrome using osilodrostat
Official title: A Block-and-Replace Therapy With Osilodrostat and Concomitant Glucocorticoid Replacement
Run by University of Michigan · NCT06430528 · Data updated 2026-11-12
This study is testing if the medication osilodrostat, combined with a specific dose of another steroid, can help people with Cushing syndrome avoid adrenal insufficiency while keeping their hormone levels balanced.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include individuals diagnosed with endogenous Cushing syndrome who are either post-surgery or not candidates for surgery and are considering osilodrostat as part of their treatment.
✕Probably not a fit
Patients currently receiving other investigational drugs or those with hypersensitivity to osilodrostat may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study aims to assess the incidence of adrenal insufficiency in patients with endogenous Cushing syndrome who are treated with osilodrostat alongside glucocorticoid replacement therapy. Participants will receive osilodrostat and a physiologic dose of methylprednisolone, with close monitoring and adjustments to medication based on cortisol levels. The study will also evaluate new biomarker steroids to ensure proper dosing and assess the safety and clinical outcomes of the treatment approach.
Why it matters
Potential benefit: If successful, this treatment could improve the management of adrenal insufficiency in patients with Cushing syndrome, leading to better health outcomes.
How similar studies have gone: While this approach is novel in its specific combination of therapies, similar studies have shown promise in managing Cushing syndrome and adrenal insufficiency.
