Kissei Pharmaceutical Co., Ltd.
EA Pharma Co., Ltd.

EA Pharma Co., Ltd.(President & CEO, Yuji Matsue; Headquarters, Chuo-ku, Tokyo)(hereinafter "EA Pharma"), a subsidiary of Eisai Co., Ltd. for the gastrointestinal disease area, and Kissei Pharmaceutical Co., Ltd. (Chairman & CEO, Mutsuo Kanzawa; Headquarters, Matsumoto City, Nagano Prefecture)(hereinafter "Kissei") announced today that EA Pharma has obtained marketing approval for "RECTABUL® 2 mg Rectal Foam 14 Doses", an ulcerative colitis treatment agent, (Development code: AJG511, hereinafter "this product") in Japan.

This product is an in-licensed product of EA Pharma from Dr. Falk Pharma (Germany). EA Pharma and Kissei have jointly developed this product for the Japanese market.

Ulcerative colitis is a kind of inflammatory bowel disease. In ulcerative colitis, ulcers develop in the colonic mucosa, with and symptoms including abdominal pain, diarrhea and hemorrhagic stool, leading to a marked decline in QOL (quality of life). In Japan, ulcerative colitis is designated intractable disease by the Ministry of Health, Labour and Welfare, and it is estimated that at least 170,000 people suffer from the disease in this country.

This product is the first foam product for rectal enema (rectal foam) in Japan. Since the dosage form is a foam, the drug stays in the rectum and the sigmoid colon after reaching them, and leakage after administration is avoided. In addition, this product is a locally active steroid and, thus, is expected to reduce steroid-related systemic side effects.

The above marketing approval is based on the studies including a PIII double-blind placebo-controlled clinical study in patients with active ulcerative colitis conducted in Japan with the primary endpoint of mucosal healing rates* measured by endoscopy at 6 weeks of rectal administration of this product twice-daily. The PIII clinical study demonstrated the superiority of this product to placebo.

EA Pharma and Kissei will distribute this product under the same brand name in Japan. With this product, the two companies will strive to make further contributions to increasing the QOL of patients and to respond to the need for easy-to-use and safe locally-active treatment of ulcerative colitis.


*Mucosal healing rates: The rates of patients in whom the colonic mucosa became normal or the disease was observed to be clinically inactive.
