EA Pharma Co., Ltd.


EA Pharma Co., Ltd. (President & CEO, Yuji Matsue; Headquarters, Chuo-ku, Tokyo) (hereinafter“EA Pharma”), Eisai Co., Ltd.’s subsidiary for the gastrointestinal disease area, announced today that it has decided to discontinue anticancer adjuvant LENTINAN for injection, as of March 31, 2018.

LENTINAN for injection has been used to treat gastric cancer for many years since its launch in 1986. However, given the advances in cancer treatment technologies and launches of new anticancer drugs, demand for LENTINAN for injection has declined, and EA Pharma has decided to discontinue the product. Discontinuation will be announced in the Official Gazette in March 2018, after which LENTINAN for injection will be designated as an Interim Measures Item until the end of March 2019.

EA Pharma will continue to provide product information as usual until the end of the Interim Measures Period*. As a Japanese specialty pharma in the gastrointestinal disease area, EA Pharma stays close to patients and strives to make contributions to patients, their families and healthcare providers through development of pharmaceuticals from a patient’s perspective.
