What Anti-IL-11 is
Blocking a single inflammatory cytokine extended healthspan and lifespan in mice, and it worked when started in already old animals. No human ageing trial exists.
This is one of the more striking mouse results in recent ageing biology, and the detail that matters is when treatment started. Interleukin-11 is a cytokine in the interleukin-6 family that rises with age and drives fibrosis and inflammatory signalling.
Mechanism: Interleukin-11 signals through a receptor complex using IL-11RA and the shared gp130 subunit, activating JAK and STAT3 and also ERK signalling. It is a driver of fibroblast activation and fibrosis across organs, and its expression rises with age.
Regulatory history: No anti-IL-11 agent is approved for any indication. Recombinant IL-11 itself, oprelvekin, was previously an approved drug for thrombocytopenia, which is the opposite intervention.
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 Anti-IL-11 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.
