Basel, June 3, 2010 - Novartis announced today that a Phase III study of Afinitor® (everolimus) tablets plus best supportive care met its primary endpoint, showing the drug significantly extended progression-free survival, or time without tumor growth, in patients with advanced pancreatic neuroendocrine tumors (NET). The study, RADIANT-3 (RAD001 In Advanced Neuroendocrine Tumors), is part of the largest clinical trial program of its kind.
Everolimus is approved under the trade name Afinitor® (everolimus) tablets for the treatment of patients with advanced renal cell carcinoma (RCC) whose disease has progressed on or after treatment with vascular endothelial growth factor (VEGF)-targeted therapy.
Pancreatic NET can grow aggressively and at time of diagnosis nearly 60% of all patients have advanced disease, meaning the cancer has spread to other parts of the body and has become more difficult to treat,. The median survival rate for patients with advanced pancreatic NET is 17 months. Currently, surgery and chemotherapy are the only approved treatment options for patients with advanced pancreatic NET.
"Everolimus was developed to inhibit the mTOR protein, which is a critical target in treating various cancers, including NET. Results from RADIANT-3 demonstrate that everolimus has the potential to become an important treatment option for patients with advanced pancreatic NET, where there is a major unmet need," said Herve Hoppenot, President, Novartis Oncology. "These study results will serve as the basis of worldwide regulatory filings for everolimus and bring us one step closer to our goal of offering these patients a new therapy."
Full results from the RADIANT-3 study will be submitted for presentation at the European Society for Medical Oncology annual meeting taking place in Milan, Italy in October. Additionally, worldwide regulatory filings are planned for 2010.
RADIANT-3 is a Phase III prospective, double-blind, randomized, parallel group, placebo-controlled, multicenter study. The trial examined the efficacy and safety of everolimus plus best supportive care versus placebo plus best supportive care in 410 patients with advanced pancreatic NET, also known as islet cell tumors. Patients who met the study's entry criteria were randomized 1:1 to receive either daily everolimus (10 mg) or daily placebo orally.
The primary endpoint of RADIANT-3 is progression-free survival. Secondary endpoints include safety, objective response rate and overall survival.
About neuroendocrine tumors
Neuroendocrine tumors arise from cells that can produce and secrete a variety of hormones that regulate bodily functions. There are many types of NET that can occur throughout the body; however, most are found in the gastrointestinal tract, pancreas and lungs. Because NET are relatively rare, there is no routine screening and patients often experience delays of five to seven years before receiving an accurate diagnosis,. As a result of this, patients with NET often have advanced disease when diagnosed. Although considered a rare cancer, the incidence of NET is increasing dramatically, having quadrupled in the past 30 years.
In the European Union (EU), everolimus is approved under the trade name Afinitor® (everolimus) tablets for the treatment of patients with advanced renal cell carcinoma (RCC) whose disease has progressed on or after treatment with vascular endothelial growth factor (VEGF)-targeted therapy. In the US, Afinitor is approved for the treatment of patients with advanced RCC after failure of treatment with sunitinib or sorafenib.
In the EU, everolimus is available in different dosage strengths under the trade name Certican® for the prevention of organ rejection in heart and kidney transplant recipients. In the US, everolimus is available in different dosage strengths under the trade name Zortress® for the prevention of rejection of kidney transplants in adult patients at low-to-moderate immunologic risk.
With once-daily dosing, Afinitor works by targeting mTOR in cancer cells, a protein that acts as a central regulator of tumor cell division, blood vessel growth and cell metabolism.
As an investigational compound, the safety and efficacy profile of everolimus has not yet been established in NET. Access to everolimus for NET has been carefully controlled and monitored in clinical trials designed to better understand the potential benefits and risks of the compound. For more information about ongoing everolimus clinical trials, healthcare professionals can visit www.theWIDEprogram.com. Because of the uncertainty of clinical trials, there is no guarantee that everolimus will become commercially available for NET anywhere in the world.
Afinitor (everolimus) tablets important safety information
Afinitor is contraindicated in patients with hypersensitivity to everolimus, to other rapamycin derivatives or to any of the excipients.
Cases of non-infectious pneumonitis have been described; some of these have been severe and occasionally fatal. Management of pneumonitis may require dose adjustment and/or interruption, or discontinuation of treatment and/or addition of corticosteroid therapy.
Afinitor is immunosuppressive. Localized and systemic bacterial, fungal, viral or protozoal infections (e.g. pneumonia, aspergillosis, candidiasis, hepatitis B reactivation) have been described; some of these have been severe and occasionally fatal. Pre-existing infections should be treated prior to starting treatment. Patients and physicians should be vigilant for symptoms and signs of infection; in case of emergent infections, appropriate treatment should be promptly instituted and interruption or discontinuation of Afinitor should be considered. Patients with systemic invasive fungal infections should not receive Afinitor.
Mouth ulcers, stomatitis and oral mucositis have been seen in patients treated with Afinitor. Monitoring of renal function, blood glucose and complete blood counts is recommended prior to initiation and periodically during treatment.
Afinitor is not recommended in patients with severe hepatic impairment. Use of live vaccines should be avoided. Afinitor is not recommended during pregnancy or for women of childbearing potential not using contraception. Afinitor may cause fetal harm in pregnant women. Women taking Afinitor should not breast feed.
