RADIANT-3 study results show everolimus significantly extends progression-free survival in patients with advanced pancreatic neuroendocrine tumors...

We know that Everolimus (RAD-001, marketed by Novartis under the  tradenames Zortress (USA) and Certican (Europe and other countries) in transplantation medicine and Afinitor in oncology) is the 42-O-(2-hydroxyethyl) derivative of sirolimus and works similarly to sirolimus as an mTOR (mammalian target of rapamycin) inhibitor. It is currently used as an immunosuppressant to prevent rejection of organ transplants. Much research has also been conducted on everolimus and other mTOR inhibitors for use in a number of cancers.

The FDA has approved everolimus for the treatment of advanced kidney cancer on March 30, 2009 and for organ rejection prophylaxis on April 22, 2010. Now Novartis Pharmaceuticals Corporation announced that the  Phase III study of Afinitor® (everolimus, see structure) 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) after failure of treatment with sunitinib or sorafenib.  

As  per the claim by   Herve Hoppenot, President, Novartis Oncology, 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.

"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."...says Herve Hoppenot...
