Product Description:

Avutometinib is an oral RAF/MEK clamp, a kinase inhibitor that holds RAF and MEK together in an inactive complex so the MAPK growth signal cannot pass down the chain. Unlike classic MEK inhibitors, it also stops RAF from switching MEK back on, an escape route that matters in KRAS-driven tumours. It is a potassium salt in 0.8 mg capsules. The 200 mg figure shown with it belongs to defactinib, a focal adhesion kinase inhibitor tablet packed and taken alongside it.

The pairing holds accelerated approval in the United States for adults with KRAS-mutated recurrent low-grade serous ovarian cancer after prior systemic treatment. Avutometinib is taken twice a week and defactinib twice a day, for three weeks of every four-week cycle, so a dosing calendar helps. Eye disorders, including blurred vision, are a known effect, and eye examinations are scheduled before and during use. Rash, raised liver enzymes and raised creatine phosphokinase are watched for. Both drugs can harm an unborn child.

Sourcing notes. This is a newly approved innovator therapy with very narrow registration, so most demand moves through named-patient or special-access import against an oncologist's prescription. Make clear whether you need the co-pack or the capsules alone, since the regimen is built on both. Keep capsules in the original container as the carton directs. Ask for the batch CoA, a traceable chain back to the authorisation holder, serialised packs with the approved leaflet and the import licence your regulator issues for unregistered medicines. Pharmacy teams apply their usual precautions for oral anticancer drugs.

Not approved in your country? A hospital or doctor can often still import it for a named patient, through a special-access, import-permit or compassionate-use route. We confirm which route applies in your country and the documents needed before quoting. Ask about named-patient supply →

Named-patient import Where a patient needs the product in a market where it is not registered, named-patient import is the lawful route. It requires the treating physician's documentation and authorisation from the destination regulator. We handle this pathway. Named-patient access
Authorised distribution For registered markets, supply runs through the manufacturer's authorised distribution channel. We can identify the authorised route for your market and tell you whether the product is registered there at all. Innovator sourcing
A genericised alternative Where the clinical requirement is the drug class rather than this specific molecule, there is often an off-patent alternative that is faster to register and materially cheaper. Tell us the indication and target market and we will say plainly whether one exists. Discuss alternatives
Licensing and generic development Patents expire country by country, and in many countries development and dossier filing can start before expiry under research and regulatory-review exemptions. We connect manufacturers developing this molecule, dossier holders, licensees and tech-transfer partners for markets where it is, or will become, off-patent. Partner on this molecule
