ACE-031
Also known as: ACVR2B-Fc, Ramatercept
- Half-life:
- ~14 days
Administration Routes
Mechanism of Action
Soluble decoy receptor for ActRIIB; sequesters myostatin, activin, and GDF-11 to remove multiple brakes on muscle and bone growth simultaneously
A soluble decoy receptor that blocks the ActRIIB pathway, inhibiting myostatin and related TGF-β family proteins. Produces dramatic muscle and bone gains but carries cardiovascular risks at high doses.
Primary Research Areas
- myostatin/activin inhibition
- muscle mass increase
- bone density improvement
Risk Profile
Higher risk profile in research contexts. Consult a healthcare professional before use.
Regulatory Status
Activin receptor IIB-Fc fusion (ACVR2B decoy) by Acceleron Pharma. Phase 2 for Duchenne MD halted 2013 due to AEs (epistaxis, telangiectasia). Development discontinued. Previously held IND.
