Could a new drug tame dangerous brain blood vessel clusters?

NCT ID NCT05085561

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This trial tests an experimental drug called REC-994 in adults with symptomatic cerebral cavernous malformation (CCM), a condition where clusters of abnormal blood vessels in the brain can cause bleeding, seizures, and other symptoms. Participants receive either a low or high dose of REC-994 or a placebo for up to a year, with a long-term extension phase. The study measures safety, symptom changes, and bleeding events to see if the drug can help control the disease.

Active substance

REC-994

What this could lead to

If successful, REC-994 could become the first drug treatment to reduce symptoms and bleeding events in people with cerebral cavernous malformation.

What could go wrong

This is a small, early-phase trial. The drug may not prove more effective than placebo, and long-term safety is still unknown.
