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.
