NEW YORK, NY, USA I February 23, 2018 I Pfizer Inc. (NYSE:PFE) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended against expanding use of SUTENT® (sunitinib) to include the adjuvant treatment of adult patients at a high risk of recurrent renal cell carcinoma (RCC) following nephrectomy (surgical removal of the cancerous kidney). The CHMP’s recommendation is not binding but will now be taken into consideration by the European Commission (EC). There is currently no approved adjuvant treatment option available for patients with non-metastatic RCC at high risk for recurrence in the European Union (EU).

In the U.S., SUTENT is approved for the adjuvant treatment of adult patients at high risk of recurrent RCC following nephrectomy.

“We remain confident in the potential of SUTENT for RCC patients at high risk of their cancer returning after surgery who today are restricted to a wait and see, or more accurately, a wait and worry approach,” said Mace Rothenberg, MD, chief development officer, Oncology, Pfizer Global Product Development. “We will continue to work closely with the European Medicines Agency as they complete their review and render a decision on this application.”

On November 16, 2017, the U.S. Food and Drug Administration approved an expanded indication for SUTENT as the first treatment for adult patients at high risk of recurrence following nephrectomy. The FDA expanded indication was based on results from the S-TRAC trial, a multicenter, international, randomized, double-blind, placebo-controlled Phase 3 trial of SUTENT versus placebo in 615 patients with clear cell histology and high risk of recurrence following nephrectomy. The results were published by The New England Journal of Medicine in October 2016.

Each year, approximately 338,000 new cases of kidney cancer are diagnosed worldwide, representing approximately 2-3 percent of all cancers.1,2,3 Approximately 75 percent of patients with clear cell RCC are non-metastatic, and 70-80 percent will have a nephrectomy with curative intent.4 Patients at high risk of recurrence represent approximately 10 percent of all patients with primary resected RCC and approximately 60 percent of these patients will recur and develop metastatic disease within five years.5

Pfizer is dedicated to addressing the unmet needs of patients and has been advancing the science of RCC for the last decade through research into established and novel compounds. Our near-term areas of focus include expanding access of our marketed products, exploration of biomarkers to better personalize therapy and immunotherapy combinations.

About SUTENT® (sunitinib malate)

Sunitinib is a small molecule that inhibits multiple receptor tyrosine kinases, some of which are implicated in tumor growth, pathologic angiogenesis, and metastatic progression of cancer. Sunitinib was evaluated for its inhibitory activity against a variety of kinases (>80 kinases) and was identified as an inhibitor of platelet-derived growth factor receptors (PDGFRα and PDGFRβ), vascular endothelial growth factor receptors (VEGFR1, VEGFR2 and VEGFR3), stem cell factor receptor (KIT), Fms-like tyrosine kinase-3 (FLT3), colony stimulating factor receptor Type 1 (CSF-1R), and the glial cell-line derived neurotrophic factor receptor (RET).

SUTENT is indicated in the U.S. for the treatment of gastrointestinal stromal tumor (GIST) after disease progression on or intolerance to imatinib mesylate; the treatment of advanced renal cell carcinoma (RCC); the adjuvant treatment of adult patients at high risk of recurrent RCC following nephrectomy; the treatment of progressive, well-differentiated pancreatic neuroendocrine tumors (pNET) in patients with unresectable locally advanced or metastatic disease.
