What Apitegromab is
An antibody against latent myostatin, under FDA review for spinal muscular atrophy (decision due September 30, 2026) and shown to preserve 55% of the lean mass otherwise lost on tirzepatide.
Apitegromab binds the pro and latent forms of myostatin so it cannot be activated, releasing the brake on muscle growth. Scholar Rock filed it for spinal muscular atrophy; a 2025 complete response letter concerned a manufacturing site only, and the resubmission carries a September 2026 decision date.
Mechanism: Monoclonal antibody that binds pro/latent myostatin and prevents its activation, increasing skeletal muscle mass.
Regulatory history: Under FDA review for SMA (PDUFA September 30, 2026); investigational in obesity
How MHRA treats this kind of product
Licenses medicines for the UK market. A compound without a marketing authorisation is an unlicensed medicine, which can only lawfully be supplied for human use through a prescriber under the specials scheme, not sold as a research product.
The classification above is the The Longevity Archive reading of Medicines and Healthcare products Regulatory Agency listings for Apitegromab 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.
