Class: Biological Therapy
Generic Name: everolimus (ever-OH-li-mus)
Trade Name: Afinitor®
How is this drug used? Afinitor is FDA-approved for the treatment of advanced renal cell carcinoma (kidney cancer) among patients whose cancer has recurred or progressed following treatment with either Sutent® (sunitinib) or Nexavar® (sorafenib); for the treatment of a benign brain tumor—subependymal giant cell astrocytoma (SEGA) associated with tuberous sclerosis—in children and adults who require treatment but are not candidates for surgical removal of the tumor; for the treatment of progressive, locally advanced or metastatic, pancreatic neuroendocrine tumors (PNET) that cannot be surgically removed and for adults with progressive, well-differentiated, non-functional neuroendocrine tumors (NET) of gastrointestinal (GI) or lung origin that are unresectable, locally advanced or metastatic; for the treatment of renal angiomyolipoma (a benign kidney tumor) in people with tuberous sclerosis; and in combination with Aromasin® (exemestane) for the treatment of advanced, hormone receptor-positive, HER2-negative breast cancer in postmenopausal women who have already been treated with certain other medications.
What is the mechanism of action? Afinitor belongs to a group of drugs referred to kinase inhibitors. Afinitor inhibits the serine-threonine kinase referred to as the mammalian target of rapamycin (mTOR). MTOR is involved in cellular replication, growth, and metabolism. Inhibition of mTOR with Afinitor has demonstrated a reduction in the replication and spread of cancer cells.
How is Afinitor given (administered)? Afinitor is given orally in the form of a tablet. You should not drink grapefruit juice or eat grapefruit during treatment with Afinitor.
How are patients monitored? Patients will usually have scheduled meetings with their healthcare provider while they are being treated with Afinitor. Typically, blood will be drawn to check levels of blood cells and to monitor functions of some organ systems, such as the liver or kidneys. Patients may also undergo physical examinations, scans or other measures to assess side effects and response to therapy.
