Takeda Pharmaceutical Company Limited

Osaka and Tokyo, Japan, October 1, 2009 --- Takeda Pharmaceutical Company Limited (Osaka, President: Yasuchika Hasegawa), AstraZeneca K.K. (Osaka, President and CEO: Masahiro Kato), Mitsubishi Tanabe Pharma Corporation (Osaka; President and CEO: Michihiro Tsuchiya), and Eisai Co., Ltd. (Tokyo; President and CEO: Haruo Naito) jointly announced today the submission of an application(*1) for additional indications for Helicobacter pylori (“H. pylori ”) eradication by concomitant therapy with three proton pump inhibitors, lansoprazole, omeprazole, and rabeprazole sodium, marketed in Japan under four brand names. This concomitant therapy consists of a proton pump inhibitor, amoxicillin hydrate, and either clarithromycin or metronidazole and is indicated for the eradication of H. pylori in gastric MALT lymphoma(*2) , the stomach after endoscopic resection of early stage gastric cancer, and idiopathic thrombocytopenic purpura(*3) (“ITP”).

Under the Japanese National Health Insurance system, the approved indications for eradication of H. pylori are currently limited to gastric and duodenal ulcers. While recent findings have revealed that the H. pylori plays a central role in the cause and pathology of a variety of diseases including gastric cancer, the Japanese Society for Helicobacter Research submitted a letter to the Minister of Health, Labour and Welfare in December 2008, requesting for the earliest possible approval of the additional indications based on the abundance of clinical evidence already published to date. In response to this, the relevant companies submitted joint applications based on the said published evidence in accordance with the “Handling of Ethical Drugs for Off-label Use”, Notification No. 4 of the Research and Development Division / Notification No. 104 of the Evaluation and Licensing Division, dated February 1, 1999.

The four companies expect that, once approved, these additional indications will significantly contribute to improving the quality of life (QOL) and prognosis of the patients with the said three diseases.
