What Pegozafermin is
A glycoPEGylated FGF21 analog dosed weekly or every two weeks, now owned by Roche and in two Phase 3 MASH trials.
Pegozafermin (from 89bio, acquired by Roche in 2025) showed fibrosis improvement in the ENLIVEN Phase 2b and is being tested in ENLIGHTEN-Fibrosis (F2/F3) and ENLIGHTEN-Cirrhosis (F4) with 52-week histology endpoints. Roche now holds an FGF21, a GLP-1/GIP dual agonist (enicepatide) and an amylin partnership, one of the broadest metabolic portfolios outside Lilly and Novo.
Mechanism: Long-acting FGF21 analog acting on FGFR1c/beta-klotho to reduce liver fat and fibrosis and improve lipids.
Regulatory history: Investigational; Phase 3
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 Pegozafermin 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.
