Summary

This trial will test the safety and effectiveness of a new drug, seliciclib, for treating Cushing disease. The trial will last 4 weeks and will involve patients who have newly diagnosed, persistent, or recurrent Cushing disease.

Who is the study for?
Adults with Cushing's disease from a pituitary source, who have high cortisol levels and are not currently well-controlled on other treatments. They must be at least 18 years old, have completed specific medication washout periods, and cannot have had pituitary radiation in the last 5 years or any major surgery within the past month.
What is being tested?
The trial is testing Seliciclib, an oral medication given for four weeks to see if it's safe and effective for treating Cushing's disease. It’s an open-label study funded by the FDA Office of Orphan Products Development.
What are the potential side effects?
Potential side effects of Seliciclib may include sensitivity reactions, liver issues (as those with liver disease were excluded), possible heart problems (QTcF prolongation was a concern), as well as general risks associated with taking new medications.
