What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a new drug called INCB000928 to help people with a rare condition called fibrodysplasia ossificans progressiva (FOP). FOP causes soft tissues to turn into bone, and there are few treatments available. The study will check if the drug is safe and effective in stopping or slowing this abnormal bone growth.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, if you have a chronic or active infectious disease requiring treatment, you may be excluded from participating.
