EA Pharma Co., Ltd. (President, Hajime Shimizu; Headquarters, Tokyo, Japan) and Mochida Pharmaceutical Co., Ltd. (President, Naoyuki Mochida; Headquarters, Tokyo, Japan) announced that the achievement of primary endpoint was met in Phase 3 clinical study of AJG533 (nonproprietary name: Elobixibat Hydrate), which the two companies have developed for treatment of chronic constipation in Japan.

Constipation is a very common disease, and the prevalence is particularly high in women and the elderly. In constipation, symptoms such as sensation of incomplete evacuation and hard stools appear in addition to reduction of bowel movement frequency. When such symptoms become chronic, many patients suffer from decline of QOL (quality of life). AJG533, which was in-licensed from Albireo (Sweden), is an orally available constipation treatment having a novel action mechanism. AJG533 inhibits the bile acid transporter that regulates reabsorption of bile acids and thereby increases spontaneous colonic motility.

The present phase 3 study is a double blind comparative study in Japan. Patients were randomized to receive AJG533 or placebo orally once daily for 14 days for investigation of efficacy and safety.

The study results demonstrated a statistically significant improvement in the AJG533 group as compared to the placebo group in the primary endpoint of spontaneous bowel movement1) frequency change and also in the efficacy secondary endpoints including complete spontaneous bowel movement2) frequency change and stool consistency. There were no serious adverse events in the study.

A long term study of AJG533 for investigation of safety and efficacy in long term use is now being conducted.

EA Pharma Co., Ltd. and Mochida Pharmaceutical Co., Ltd. are advancing the development of AJG533 with the aim of filing a new drug application in FY2016. By providing AJG533, the two companies are striving to make a further contribution to increasing treatment options and improvement of QOL for patients with chronic constipation.

1) defacation without use of laxative, enema or manual disimpaction
2) spontaneous defacation without sensation of incomplete evacuation
