Class: Chemotherapy

Generic Name: Everolimus (ever-OH-li-mus)
Trade Name: Afinitor®

How is this drug used? Everolimus 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). It is important for patients to remember that physicians have the ability to prescribe medication for conditions other than those for which the drug has been approved by the FDA. Patients who have received a prescription of this drug for a condition other than for which it is approved may wish to discuss this issue with their physician.

What is the mechanism of action? Everolimus belongs to a group of drugs referred to kinase inhibitors. Everolimus 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 everolimus has demonstrated a reduction in the replication and spread of cancer cells.

How is everolimus given (administered)? Everolimus is given orally in the form of a 5 or 10 mg tablet. The daily dose depends on several factors, including side effects incurred from treatment, the overall health of the patient and other treatment being used. Everolimus may be taken with or without food.
Allergic-type reactions, although rare, may occur following treatment with everolimus. These reactions are characterized by difficulty breathing, low blood pressure, lightheadedness or dizziness. Patients will be monitored for these reactions.

How are patients monitored? Patients will usually have scheduled meetings with their healthcare provider while they are being treated with everolimus. 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.
