Could a transplant drug shrink dangerous blood vessel tangles?
NCT ID NCT02042326
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether sirolimus, a drug used to prevent organ rejection, can shrink severe arteriovenous malformations (AVMs) and ease symptoms. About 50 people aged 2 and older with advanced AVMs will take the drug for a year. The goal is to see if the drug reduces AVM size by at least 30% and stops it from growing, but participants may need ongoing treatment.
