Video: Afinitor(R) Approved in US as First Treatment for Patients With Advanced Kidney Cancer After Failure of Either Sunitinib or Sorafenib
- Afinitor more than doubled time without tumor growth and reduced the risk of disease progression or death by 67% compared with placebo
- Only once-daily oral cancer treatment to directly target mTOR, a protein inside the cell that controls tumor cell division and blood vessel growth
- Phase III trials underway to explore potential of Afinitor in multiple additional cancers

Prior to Afinitor, no other therapy has been studied in a Phase III trial in this patient population where there is an important unmet medical need(1). Sutent and Nexavar are commonly used as initial treatments for advanced RCC(2).
The approval is based on data that showed Afinitor, when compared with placebo, more than doubled the time without tumor growth or death in patients with advanced kidney cancer (4.9 vs. 1.9 months) and reduced the risk of disease progression or death by 67% (hazard ratio=0.33 with 95% confidence interval 0.25 to 0.43; P<0.0001)(3). Furthermore, additional data show that after 10 months of treatment with Afinitor, approximately 25% of patients still had no tumor growth(1) ***.
“This approval provides a new and useful tool for treating advanced renal cell cancer, representing an important step forward in managing this disease,” said
In 2008, the FDA granted priority review status to Afinitor, previously known as RAD001, based on its potential to fill an unmet medical need for patients with advanced kidney cancer. Novartis has filed regulatory submissions in the European Union,
Afinitor inhibits mTOR, a protein in the cancer cell that controls tumor cell division and blood vessel growth. Preclinical and clinical data have established the important role of mTOR in the development and progression of several types of tumors(1).
“With this approval, we can now offer patients a targeted therapy proven to fulfill an important unmet need in the treatment of advanced kidney cancer,” said
About renal cell carcinoma
Renal cell carcinoma is often referred to as kidney cancer. Kidney cancer accounts for approximately 2% of all new cancers(4). RCC is the most common type of kidney cancer, with occurrence rates rising steadily around the world due in part to smoking and obesity(5,6). It is estimated that about 54,000 new cases of RCC developed in the US in 2008 and more than 13,000 people died from the disease(7).
In RCC, cancer cells develop in the lining of the kidney’s tubes and grow into a tumor(8). If left untreated, the tumor can spread to neighboring lymph nodes and eventually other organs(9).
The FDA regulatory filing for Afinitor was based on data from RECORD-1 (REnal Cell cancer treatment with Oral RAD001 given Daily), the largest Phase III clinical trial to study the effects of an oral mTOR inhibitor in advanced RCC patients whose cancer progressed despite prior treatment with sunitinib, sorafenib or both sequentially. In
This international, multi-center, randomized, double-blind trial involved 416 patients with advanced RCC whose cancer progressed despite prior treatment with sunitinib, sorafenib or both sequentially. In addition, prior therapy with bevacizumab, interferon alfa and interleukin-2 was allowed. Patients were randomized to receive Afinitor (10 mg) daily or placebo, in conjunction with best supportive care. The primary endpoint of the study was progression-free survival, which was assessed via a blinded independent, central radiological review(10).
Afinitor is the first oral, daily therapy (5 mg and 10 mg tablets) to treat advanced kidney cancer after failure of treatment with sunitinib or sorafenib. In cancer cells, Afinitor continuously targets mTOR, a protein that acts as a central regulator of tumor cell division, blood vessel growth and cell metabolism. Afinitor is also being studied in multiple cancer types, including neuroendocrine, breast, gastric and hepatocellular carcinoma (HCC), as well as tuberous sclerosis complex (TSC) and non-Hodgkin’s lymphoma(11).
The active ingredient in Afinitor is everolimus, which is available in different dosage strengths under the trade name Certican(R) for the prevention of organ rejection in heart and kidney transplant recipients. Certican was first approved in the EU in 2003. Certican is not approved for use in the US(1).

Important safety information
Afinitor is contraindicated in patients with hypersensitivity to everolimus, to other rapamycin derivatives or to any of the excipients. Potentially serious adverse reactions include non-infectious pneumonitis and infections for which patients should be monitored carefully and treated as needed. In addition, non-infectious pneumonitis may require temporary dose reduction and/or interruption or discontinuation. Patients with systemic invasive fungal infections should not receive Afinitor. Oral ulceration is a common side effect with Afinitor. Renal function, blood glucose, lipids and hematological parameters should be evaluated prior to the start of therapy with Afinitor and periodically thereafter. Strong or moderate CYP3A4 or P-glycoprotein inhibitors should be avoided. An increase in the dose of Afinitor is recommended when co-administered with a strong CYP3A4 inducer. Live vaccinations and close contact with those who have received live vaccines should be avoided. Afinitor should not be used in patients with severe hepatic impairment. Afinitor may cause fetal harm in pregnant women.
The most common adverse reactions (incidence greater than or equal to 30%) were stomatitis, infections, asthenia, fatigue, cough and diarrhea. The most common grade 3/4 adverse reactions (incidence greater than or equal to 3%) were infections, dyspnea, fatigue, stomatitis, dehydration, pneumonitis, abdominal pain and asthenia. The most common laboratory abnormalities (incidence greater than or equal to 50%) were anemia, hypercholesterolemia, hypertriglyceridemia, hyperglycemia, lymphopenia and increased creatinine. The most common grade 3/4 laboratory abnormalities (incidence greater than or equal to 3%) were lymphopenia, hyperglycemia, anemia, hypophosphatemia and hypercholesterolemia. Deaths due to acute respiratory failure (0.7%), infection (0.7%) and acute renal failure (0.4%) were observed for patients receiving Afinitor.
