FDA approves cancer drug Afinitor for treatment of rare genetic disorder

 We know that Afinitor ( see structure) is an inhibitor of mTOR (mammalian target of rapamycin), a serine-threonine kinase, downstream of the PI3K/AKT pathway. The mTOR pathway is dysregulated in several human cancers. Everolimus binds to an intracellular protein, FKBP-12, resulting in an inhibitory complex formation and inhibition of mTOR kinase activity. Inhibition of mTOR by everolimus has been shown to reduce cell proliferation, angiogenesis, and glucose uptake in in vitro and/or in vivo studies.

Afinitor is specifically indicated for the treatment of advanced renal cell carcinoma after failure of treatment with sunitinib or sorafenib. Afinitor is supplied as a 5 mg or 10 mg tablet designed for oral administration. The recommended initial dose of the drug is 10 mg, to be taken once daily at the same time every day, either with or without food. Afinitor tablets should be swallowed whole with a glass of water; they should not be chewed or crushed....Now FDA approves the drug....
