ACE-031

Also known as: ActRIIB-Fc

Muscle Biology ResearchGrowth Factor Research
ClassificationRecombinant fusion protein of the activin type IIB receptor extracellular domain and an IgG Fc region.
TargetsActRIIB ligand trapping; Myostatin pathway models

Molecular Overview

ACE-031 is a soluble ActRIIB decoy receptor that was investigated clinically as a myostatin-pathway ligand trap before development was halted.

Mechanistic Background

Binds myostatin and related ligands, preventing ActRIIB receptor engagement in experimental models.

What Researchers Study

Phase 1/2 clinical publications and preclinical muscle-biology literature.

Evidence Landscape

Current evidence level: EARLY TRANSLATIONAL. Preclinical evidence does not equate to demonstrated human efficacy.

Research Limitations

Clinical development discontinued due to safety signals; research use only.
