What ACE-031 is
A myostatin/activin decoy studied for muscular dystrophy whose trials were halted over vascular safety signals.
ACE-031 is a soluble form of the activin receptor type IIB that acts as a decoy, trapping myostatin and related factors to promote muscle growth. It was studied for Duchenne muscular dystrophy, but trials were halted in 2011 after signals including nosebleeds and small vessel changes.
Mechanism: Binds and neutralizes myostatin and activin before they can signal, releasing their inhibition of muscle growth.
Regulatory history: Not FDA-approved; development halted on safety grounds
How Health Canada treats this kind of product
Authorises drugs for sale through a Notice of Compliance and Drug Identification Number. A compound that is not authorised for sale cannot lawfully be sold for human use, and personal importation of prescription drugs is limited.
The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch listings for ACE-031 at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
