Kissei Pharmaceutical Co., Ltd.
Aspen Japan K.K



Kissei Pharmaceutical Co., Ltd. (Head office: Matsumoto-city, Nagano, Chairman and CEO: Mutsuo Kanzawa; "Kissei") and Aspen Japan K.K. (Head office: Shinjuku-ku, Tokyo, Chairman: Shingo Iwamoto; "Aspen Japan") have announced a co-promotion agreement for Imuran® Tablets 50 mg, an immunosuppressant (with azathioprine as active pharmaceutical ingredient). Aspen Japan is the authorized marketing holder of the product in the country and the co-promotion takes effect in January 2017.

Under the terms of the agreement, both parties will jointly perform promotion activities for Imuran® Tablets 50 mg to medical institutions and other organizations. Aspen Japan will continue to oversee the manufacturing, marketing, and distribution of this product.

Imuran® Tablets 50 mg is a 6-mercaptopurine (6-MP) product with an immunosuppressive effect. The active pharmaceutical ingredient, azathioprine, is rapidly converted into 6-MP in vivo and inhibits nucleic acid synthesis to produce immunosuppressive effect. Azathioprine has been used for the prevention of rejection in renal transplants for over 30 years. It is also widely used for the treatments of inflammatory bowel diseases such as ulcerative colitis and Crohn's disease and treatment-resistant rheumatic diseases.

The partnership will enable Kissei and Aspen Japan to further enforce and enhance activities to provide Imuran® Tablets 50mg product information and to contribute to improving the Quality of Life (QOL) of more patients.
