Summary

This trial will study a new drug to treat Cushing's Syndrome, a hormone disorder, to see if it is safe and effective.

Who is the study for?
This trial is for adults aged 18-75 with active ACTH-dependent Cushing's syndrome, vaccinated against COVID-19. Participants on short-term steroid inhibitors can join after a washout period. It excludes pregnant or lactating women, those with certain pituitary issues, recent unsuccessful surgery for Cushing's, and anyone with known cancer or extremely high urine cortisol levels.
What is being tested?
The study tests CRN04894 in people with Cushing's syndrome to see how safe it is and how the body processes it. This drug blocks the action of ACTH which causes overproduction of cortisol. The trial involves increasing doses to find out what amount works best without being harmful.
What are the potential side effects?
Potential side effects aren't specified but may include reactions related to lowering cortisol production too much such as fatigue, nausea, dizziness or potentially affecting other hormones regulated by ACTH.
