Is Lanifibranor legal in the United Kingdom?

A daily pill for fatty liver disease that works on all three PPAR switches. Its 1,000-person final-stage study finished in September 2026, with results due by the end of the year.

Lanifibranor switches on all three PPAR receptors, called alpha, delta and gamma. These control how the liver handles fat, inflammation and scarring, and how the body uses insulin.

How it works: It switches on all three PPAR receptors. That improves how the liver handles fat, and it calms inflammation and the cells that lay down scar tissue.

Approval history: Investigational; a final-stage study has finished giving doses

Licenses medicines for sale in the UK. A compound without a licence to be sold (a marketing authorisation) is an unlicensed medicine. The law only lets it reach people through a prescriber, under the specials scheme (unlicensed medicines made for one patient's needs). It cannot be sold as a research product.

The legal category above is how The Longevity Archive reads Medicines and Healthcare products Regulatory Agency listings for Lanifibranor on the reviewed date. It is not a legal opinion.

Whether Lanifibranor is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in the United Kingdom. Before you compete or get tested, look up Lanifibranor by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
