Eisai Co., Ltd. announced today that it has submitted applications to regulatory authorities in the U.S. and Europe (the FDA and EMA respectively) for marketing approval of its novel in-house developed anticancer agent lenvatinib mesylate (lenvatinib) as a treatment for progressive radioiodine-refractory differentiated thyroid cancer (RR-DTC).

An application seeking marketing approval of lenvatinib for the indication of thyroid cancer was submitted in Japan on June 26, 2014. Lenvatinib was granted Orphan Drug Designation for thyroid cancer in Japan, Europe and the U.S. Lenvatinib was also granted an accelerated assessment in Europe by the EMA, as it is a new medicine expected to be of major public health interest, particularly from the viewpoint of therapeutic innovation.

Lenvatinib is an oral multiple receptor tyrosine kinase (RTK) inhibitor with a novel binding mode that selectively inhibits the kinase activities of several different RTKs including VEGFR, FGFR, PDGFRα, KIT and RET, involved in angiogenesis and tumor proliferation. This potentially makes lenvatinib a first-in-class treatment in thyroid cancer, especially given that it simultaneously inhibits the kinase activities of FGFR as well as VEGFR.
