Novartis drug Afinitor® recommended by FDA oncology advisory committee for approval to treat advanced NET of pancreatic origin

  • Committee votes unanimously in favor of everolimus to treat patients with advanced neuroendocrine tumors (NET) of pancreatic origin
  • Phase III results showed everolimus more than doubled median progression-free survival from 4.6 to 11.0 months when compared with placebo in patients with advanced pancreatic NET[1]
  • Everolimus represents a targeted approach for the treatment of patients with advanced pancreatic NET, for which there are limited options[1],[2],[3]

Basel, April 12, 2011 - Novartis announced today that the US Food and Drug Administration (FDA) Oncologic Drugs Advisory Committee (ODAC) recommended approval of Afinitor® (everolimus) tablets for the treatment of patients with advanced neuroendocrine tumors (NET) of pancreatic origin.

The recommendation was provided after presentation of data from the everolimus RADIANT (RAD001 In Advanced Neuroendocrine Tumors) trial program, the largest conducted in patients with advanced NET. The Phase III RADIANT-3 trial studied patients with advanced NET of pancreatic origin and showed a statistically significant improvement in progression-free survival with everolimus versus placebo[1].

The FDA can seek the advice of its advisory committees as it reviews and decides whether to approve treatments, although it is not obliged to follow the recommendation[4],[5].

"We look forward to working with the FDA as it completes its review and we are encouraged by the advisory committee's recommendation to approve everolimus for patients with advanced pancreatic NET," said Hervé Hoppenot, President, Novartis Oncology. "The study of everolimus in this patient population is an example of our commitment to identify targeted options for patients with critical unmet medical needs."

When pancreatic NET becomes advanced, meaning the cancer has spread to other parts of the body, it is considered aggressive and difficult to treat[6]. Approximately 60% of pancreatic NET patients are diagnosed with advanced disease, and the five-year survival rate for these patients is 27%[3],[7].

Everolimus targets mTOR, a protein that acts as an important regulator of tumor cell division, blood vessel growth and cell metabolism[2]. Preclinical and clinical data have established the role of mTOR in the development and progression of several types of tumors, including advanced pancreatic NET, for which there are limited treatment options[1],[2],[3].

Earlier this year, the FDA granted everolimus priority review designation for the application and proposed indication for the treatment of advanced NET of gastrointestinal (GI), lung or pancreatic origin. Based on feedback from the FDA, Novartis amended the proposed indication to focus on patients with one specific type of NET, advanced NET of pancreatic origin.

Priority review status is granted to therapies that offer major advances in treatment or provide a treatment where no adequate therapy exists. This status accelerates the standard review time from 10 to six months[8]. There is the potential that the outcome of an ODAC meeting could result in the FDA extending the review period.

Worldwide regulatory filings for everolimus as a treatment for advanced NET of GI, lung or pancreatic origin are being reviewed by health authorities.

About pancreatic neuroendocrine tumors (NET)
Neuroendocrine tumors arise from cells that can produce and secrete a variety of hormones that regulate bodily functions[9]. These tumors can occur anywhere in the body; however, most are found in the pancreas, gastrointestinal tract or lungs[7],[10]. Pancreatic NET, also known as islet cell tumors, is a rare type of cancer that is different from pancreatic exocrine cancer, generally referred to as pancreatic cancer[6],[11]. There are currently limited treatment options for pancreatic NET patients[3].

About RADIANT-3
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 (BSC) versus placebo plus BSC in 410 patients with advanced, low- or intermediate-grade pancreatic NET. Patients who met the study entry criteria were randomized 1:1 to receive either everolimus 10 mg once-daily (n=207) or daily placebo (n=203) orally, both in conjunction with BSC[1].

The primary endpoint of RADIANT-3 is progression-free survival (PFS). Secondary endpoints include safety, objective response rate (confirmed according to RECIST), duration of response and overall survival[1].

Results from the trial showed that everolimus more than doubled median PFS from 4.6 to 11.0 months when compared with placebo and reduced the risk of cancer progression by 65% (hazard ratio=0.35 [95% CI, 0.27 to 0.45]; p<0.001) in patients with advanced pancreatic NET[1].

In the study, everolimus maintained a safety profile consistent with the prescribing information and previous studies of the drug. The most frequent all grade, drug-related adverse events (>=20%) were stomatitis/oral mucositis/ulcers (64% everolimus vs. 17% placebo; includes stomatitis, aphthous stomatitis, mouth ulceration and tongue ulceration), rash (49% vs. 10%), diarrhea (34% vs. 10%), fatigue (31% vs. 14%), infections (23% vs. 6%), nausea (20% vs. 18%), peripheral edema (20% vs. 3%) and decreased appetite (20% vs. 7%); most were grade one or two. Grade three and four adverse events (>=5%) include stomatitis/oral mucositis/ulcers (7% vs. 0%; includes stomatitis, aphthous stomatitis, mouth ulceration and tongue ulceration), anemia (6% vs. 0%) and hyperglycemia (5% vs. 2%). Median exposure to everolimus was 2.3-fold longer than exposure to placebo (38 vs. 16 weeks)[1].

About Afinitor (everolimus)
Afinitor® (everolimus) tablets is approved in the European Union (EU) 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 and also in the US for the treatment of patients with advanced RCC after failure of treatment with sunitinib or sorafenib.

Afinitor is also approved in the US to treat patients with subependymal giant cell astrocytoma (SEGA) associated with tuberous sclerosis who require therapeutic intervention but are not candidates for curative surgical resection. The effectiveness of Afinitor is based on an analysis of change in SEGA volume. Clinical benefit such as improvement in disease-related symptoms or increase in overall survival has not been shown. Novartis has submitted marketing applications for everolimus for this use to the European Medicines Agency (EMA) and the Swiss Agency for Therapeutic Products (Swissmedic), and additional regulatory submissions are under way worldwide.

In the EU, everolimus is available in different dosage strengths for the non-oncology patient population 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 prophylaxis of organ rejection in adult patients at low-moderate immunologic risk receiving a kidney transplant.

Everolimus is exclusively licensed to Abbott and sublicensed to Boston Scientific for use in drug-eluting stents.

Not all indications are available in every country. As an investigational compound the safety and efficacy profile of everolimus has not yet been established in pancreatic or any other type of NET. Access to everolimus outside of the approved indications has been carefully controlled and monitored in clinical trials designed to better understand the potential benefits and risks of the compound. Because of the uncertainty of clinical trials, there is no guarantee that everolimus will become commercially available for pancreatic or any other type of NET or any additional indications anywhere in the world.
