ACE-031

ACE-031 is an investigational soluble ActRIIB-Fc fusion protein designed to bind myostatin and related ligands. Human studies used defined clinical material in healthy volunteers and ambulatory boys with Duchenne muscular dystrophy; a separate preclinical paper examined a soluble ActRIIB receptor construct. Those findings do not establish interchangeability with an independently sourced batch. The current wholesale price list contains one entry marked 1 / Injectable, but the dosage unit and exact construct must be confirmed before ordering.

Technical Specifications

ClassInvestigational soluble activin receptor type IIB Fc-fusion protein.
Construct identityConfirm the ActRIIB extracellular-domain boundaries, Fc design, expression host, glycosylation profile and intact mass.
Listed presentation1 / Injectable. The current wholesale price list does not state the dosage unit.
Purity and aggregationUse orthogonal batch methods such as SEC and SDS-PAGE; a single area-purity percentage does not establish monomer state or biological activity.
ActivityConfirm the ligand-binding or cell-based activity method and acceptance criteria for the allocated batch.
Formulation and handlingConfirm buffer, excipients, endotoxin result, shipping temperature and in-use window for the supplied vial.

Clinical and preclinical ACE-031 evidence

  • ActRIIB ligand-trap research
  • Myostatin and activin signaling
  • Fc-fusion construct characterization
  • Ligand-binding and cell-based activity assays
  • Muscle-related preclinical and early clinical literature

What to verify before ordering ACE-031

ACE-031 is an Fc-fusion biologic. The product name and a generic purity figure are not enough to establish construct identity, monomer state or activity.

Construct and host

Request the expressed domain boundaries, Fc sequence, expression host, glycosylation information and an intact-mass or peptide-mapping identity result.

Aggregation and activity

Review SEC and SDS-PAGE results alongside a relevant ligand-binding or cell-based activity assay. Confirm the acceptance criteria used for the batch.

Formulation and transport

Confirm fill amount, dosage unit, buffer, excipients, endotoxin reporting, shipping temperature and reconstituted-use window.

Published ACE-031 studies used defined investigational material. Their outcomes are not a specification for independently supplied material.

Research evidence for ACE-031

Attie et al. (2012). A single ascending-dose study of muscle regulator ACE-031 in healthy volunteers. Muscle & Nerve. DOI: 10.1002/mus.23539

Study scope: Healthy volunteers in a single ascending-dose clinical study. Defined investigational ACE-031 ActRIIB-Fc clinical material.

What it supports: Supports discussion of early human tolerability, pharmacology and muscle-related measures after a single administration.

Boundary: It does not establish chronic therapeutic efficacy, outcomes in other populations or equivalence with a supplier batch.

Campbell et al. (2016). Myostatin inhibitor ACE-031 treatment of ambulatory boys with Duchenne muscular dystrophy: Results of a randomized, placebo-controlled clinical trial. Muscle & Nerve. DOI: 10.1002/mus.25268

Study scope: Ambulatory boys with Duchenne muscular dystrophy. Defined investigational ACE-031 clinical material and the trial's dosing schedule.

What it supports: Supports a bounded description of the studied pediatric DMD population, measured outcomes and safety observations.

Boundary: The results cannot be generalized to healthy adults, other diseases, unspecified dosing or independently sourced ACE-031.

Cadena et al. (2010). Administration of a soluble activin type IIB receptor promotes skeletal muscle growth independent of fiber type. Journal of Applied Physiology. DOI: 10.1152/japplphysiol.00866.2009

Study scope: An animal skeletal-muscle model. A soluble activin type IIB receptor construct used in the study; it must not be assumed to be identical to any supplier batch.

What it supports: Supports discussion of soluble ActRIIB-receptor biology and skeletal-muscle effects in the reported preclinical model.

Boundary: It is not human clinical evidence and does not prove that a differently sourced Fc-fusion construct is equivalent.

Frequently Asked Questions About ACE-031

ACE-031 is an investigational soluble ActRIIB-Fc fusion protein designed as a ligand trap for myostatin and related TGF-beta-family ligands.

The current wholesale price list contains one entry marked 1 / Injectable. The dosage unit and exact construct are not stated and must be confirmed in the quote.

For orders meeting 100+ total units, the listed ACE-031 tiers are $8.16 for 10–24 units of the SKU, $7.14 for 25–49 and $6.12 for 50+ units.

ACE-031 is an Fc-fusion protein. Buyers also need construct identity, monomer and aggregate data, glycosylation information and a relevant activity result.

No. The studies used defined investigational ACE-031 material and study-specific formulations. They do not establish batch interchangeability.

Confirm the buffer, excipients, fill amount, endotoxin result, shipping temperature, allowed freeze-thaw exposure and the in-use window for the supplied batch.
