Pivotal Phase 3 Trial of Investigational Agent Lenvatinib in Progressive, Radioactive Iodine-Refractory Differentiated Thyroid Cancer Published in New England Journal of Medicine

WOODCLIFF LAKE, N.J., Feb. 12, 2015 /PRNewswire/ -- Results from the pivotal Phase 3 SELECT (Study of (E7080) LEnvatinib in Differentiated Cancer of the Thyroid) trial evaluating the use of investigational agent lenvatinib in the treatment of progressive, radioactive iodine-refractory differentiated thyroid cancer (RAI-refractory DTC) were published online today in the New England Journal of Medicine (NEJM).

The article, "Lenvatinib versus Placebo in Radioiodine-Refractory Thyroid Cancer," reports the results of the multicenter, randomized, double-blind, placebo-controlled Phase 3 study that evaluated lenvatinib versus placebo in 392 patients with RAI-refractory DTC who had progressed within the prior 12 months.

"For patients who undergo surgery and radioactive iodine treatment, but still progress to RAI-refractory DTC, the prognosis is poor and there are currently few effective therapies available," said Professor Martin Schlumberger, Primary Investigator and M.D., Institut Gustave Roussy, University Paris Sud, Paris, France.

"We are encouraged by the publication of these data in the New England Journal of Medicine," said Kenichi Nomoto, Ph.D., President, Oncology Product Creation Unit at Eisai Inc. "As a human health care company, Eisai is committed to quality research and development to discover and deliver needed treatment options to patients."

Lenvatinib is under review with the FDA and is not currently approved for use in the United States. For more information, visit www.nejm.org.

About Lenvatinib
Lenvatinib, discovered and developed by Eisai, is a receptor tyrosine kinase inhibitor that inhibits the kinase activities of vascular endothelial growth factor (VEGF) receptors (VEGFR1 (FLT1), VEGFR2 (KDR) and VEGFR3 (FLT4)), in addition to other oncogenic pathway-related tyrosine kinases including fibroblast growth factor receptors (FGFR), the platelet-derived growth factor (PDGF) receptor PDGFRα, KIT and RET. Eisai was granted Orphan Drug Designation (ODD) for lenvatinib in various types of thyroid cancer in the United States, Japan, and Europe. It is currently under investigation in thyroid, hepatocellular, endometrial, non-small cell lung cancer, and other solid tumor types.

About the SELECT Trial
The SELECT (Study of (E7080) LEnvatinib in Differentiated Cancer of the Thyroid) study was a multicenter, randomized, double-blind, placebo-controlled Phase III study to compare the progression-free survival of patients with RAI-refractory DTC and radiographic evidence of disease progression within the prior 12 months, treated with lenvatinib versus placebo. The study enrolled 392 patients in 117 sites in Europe, North and South America and Asia and was conducted by Eisai in collaboration with the SFJ Pharmaceuticals Group.

About Thyroid Cancer
Thyroid cancer refers to cancer that forms in the tissues of the thyroid gland, located at the base of the throat near the trachea. It is more common in women than in men and most are in their 40s or 50s at time of diagnosis. Thyroid cancer is the most common endocrine malignancy and global figures show that its incidence has increased significantly over the last 50 years.

The most common types of thyroid cancer, papillary and follicular (including Hurthle cell), are classified as differentiated thyroid cancer (DTC) and account for approximately 90% of all cases. While most DTC patients are curable with surgery and radioactive iodine treatment, the prognosis for those patients whose DTC persists or recur is poor. There are limited treatment options for radioactive iodine-refractory DTC.
