Transfer of Marketing Rights for "Inteban", "Catlep" and "Drenison"

Dainippon Sumitomo Pharma Co., Ltd. ("DSP") (Head Office: Osaka, Japan; President: Masayo Tada) and Teikoku Seiyaku Co., Ltd. ("Teikoku Seiyaku") (Head Office: Kagawa, Japan; President Misako Fujioka) announced today that the two companies have concluded a Memorandum of Understanding concerning transfer of DSP's marketing rights for "Inteban®", "Catlep®" and "Drenison®" to Teikoku Seiyaku, effective July 1, 2014.

DSP's basic strategy to maintain and expand its business in Japan is to concentrate its resources on growth products such as strategic and new products, thus raising the ratio of drugs with exclusivity in its product line and realizing higher management efficiency. Teikoku Seiyaku draws on many years of experience and expertise in the field of anti-inflammatory and analgesic plasters to solidify its leader position in poultices, focusing on two directions: transdermal absorption and pain-relief. The agreement reached this time represents a good fit of the business strategies of the two companies.

Inteban® and Catlep® contain the same active ingredient, indometacin, which is a long-selling analgesic, antipyretic and anti-inflammatory agent since its first synthesis in 1963. Following their respective launches in 1968 and 1989, Inteban® and Catlep® have been used extensively in healthcare organizations. Both products are available in several different formulations so as to meet a variety of medical needs. Drenison® was first approved in the U.S. in 1969; import into Japan was approved in 1972. It is widely used for occlusive dressing to treat skin diseases.

The marketing and sale of Inteban®, Catlep® and Drenison®, together with the information provision to medical care providers, will continue to be made by DSP until June 30, 2014. Also, DSP will be responsible for the physical distribution of these products to pharmaceuticals wholesalers even after July 1, 2014 as contractor to Teikoku Seiyaku.
