Everolimus inhibits mTOR (mammalian target of rapamycin), a serine/threonine kinase that regulates a variety of key cellular processes and is upregulated in several types of cancer.
In a Phase III trial in 416 patients with metastatic renal cell carcinoma whose disease had progressed despite VEGF-targeted treatment with sunitinib and/or sorafenib, the median duration of progression-free survival was 4.9 months on everolimus compared with 1.9 months on placebo.
Afinitor is not recommended for patients with severe hepatic impairment.
