Mochida Pharmaceutical Co., Ltd.

EA Pharma Co., Ltd. (President, Yuji Matsue; Headquarters, Tokyo, Japan) (hereinafter “EA Pharma”), a subsidiary of Eisai Co., Ltd. for the gastrointestinal disease area, and Mochida Pharmaceutical Co., Ltd. (President, Naoyuki Mochida; Headquarters, Tokyo, Japan) (hereinafter “Mochida”) announced today that EA Pharma has filed an application for marketing and manufacturing approval of chronic constipation treatment AJG555 (polyethylene glycol preparation), which EA Pharma and Mochida have developed for the Japanese market.

AJG555 is an oral chronic constipation treatment that EA Pharma in-licensed from Norgine B.V. (Headquarters, the Netherlands). AJG555 controls osmotic pressures in the intestinal tract and promotes bowel movement. This product has been mainly marketed in Europe and in other markets, under the brand name MOVICOL, and widely used for treatment of chronic constipation in pediatric and adult patients. The guidelines of NICE (National Institute for Health and Care Excellence) UK endorse the use of polyethylene glycol preparations for treatment of pediatric chronic constipation, and so do the guidelines of World Gastroenterology Organisation for treatment in adults.

Constipation is a very common disease. The prevalence is particularly high in women and in the elderly, and the symptoms can become severe in pediatric patients. The symptoms of constipation are reduced bowel movements, feeling of incomplete evacuation, hard stools and others. When the symptoms become chronic, many patients suffer from a decline of QOL (Quality of Life).

Once EA Pharma has obtained the marketing and manufacturing approval of AJG555, EA Pharma and Mochida will distribute the product in Japan respectively under a same brand name. The two companies have jointly developed another chronic constipation treatment AJG533 of a different action mechanism from that of AJG555 (AJG533 is now being reviewed by the regulatory authorities for marketing and manufacturing approval). By providing AJG555 and AJG533, EA Pharma and Mochida desire to add treatment options for patients suffering from chronic constipation with different disease histories to make a contribution to fulfillment of various needs and increase of benefits of patients with chronic constipation, their families and medical practitioners.
