Eisai China Inc. Signs License Agreement in China for α-Lipon 300 STADA® for Diabetic Neuropathic Pain

Eisai Co., Ltd. (Headquarters: Tokyo, President & CEO: Haruo Naito) announced today that Eisai China Inc. (Headquarters: Suzhou, President: Yukio Akada, “ECI”), a wholly-owned subsidiary of Eisai Co., Ltd., has entered into license agreement with Health Vision Enterprise Ltd. (Headquarters: Hong Kong, Directors: Alex Leung and Zona Yim, “Health Vision”), a sales subsidiary of STADA Arzneimittel AG (Headquarters: Germany, “STADA”), for sales and repack of α-Lipon 300 STADA® (generic name: α-lipoic acid) in China. α-Lipon 300 STADA® is a treatment for diabetic neuropathic pain developed by STADA.

With this agreement, ECI will take over sales promotion activities for α-Lipon 300 STADA® in China from Health Vision from August 1. In addition, ECI will prepare for filing an application for repacking the product at its Suzhou plant. Upon approval, ECI will assume repacking and sales of α-Lipon 300 STADA® in China.

α-Lipon 300 STADA® is a therapeutic agent for diabetic neuropathic pains developed by STADA, and has been on the market in China since 2005. It relieves neuropathic pain associated with diabetes by its antioxidant effect, which reduces overproduction of oxygen species and normalization of glucose metabolism.

Recently, the incidence of diabetes in China has been increasing by about 10% every year, as part of a result of rapid economic growth. Currently, it is estimated that there are more than 30 million patients with diabetes and the number is expected to reach 46 millions in 2025. Diabetic neuropathy is one of the common complications associated with diabetes and may lead to paresthesia, which causes problems such as pain or numbness in the end of the fingers and toes. α-Lipon 300 STADA® is used to treat these symptoms.

Eisai believes that the addition of α-Lipon 300 STADA®, together with its existing products Methycobal®, a treatment for peripheral nerve disorder and Glufast®, a rapid-acting insulin secretagogue which is being filed for approval, will strengthen Eisai's capabilities in the diabetic therapeutic area in China. Eisai is committed to make further contributions to increasing the quality of life of diabetic patients in China and will continue to enrich its product lineup with in-house products, as well as in-licensed strategic products that will serve the needs of the people in China.
