Sanko Junyaku Co., Ltd.

Sanko Junyaku Co., Ltd. (Headquarters: Tokyo, President & CEO: Keisuke Watanabe, “Sanko Junyaku”), the diagnostics subsidiary of Eisai Co., Ltd. (Headquarters: Tokyo, President & CEO: Haruo Naito, “Eisai”), and SEKISUI MEDICAL CO., LTD. (Headquarters: Tokyo, President & CEO: Mutsumi Fukuda, “Sekisui Medical”) today signed an exclusive marketing agreement concerning RapidTesta® FLU II (“Kit”), an influenza test kit currently manufactured and marketed by Sekisui Medical. Under the terms of the agreement, Sanko Junyaku will acquire the exclusive right to market the Kit in Japan.

The Kit is a diagnostic test kit used to detect type A and type B influenza virus antigens in nasal suction fluid or from a nasal swab. It requires no special instruments and can be used simply and rapidly at the bedside or in the clinic. The Kit is valuable in that it provides results almost immediately and is noted for its high specificity.

Sanko Junyaku plans to launch the Kit in Japan in the middle on January 2011. With marketing support from Eisai and cooperation from Sekisui Medical, Sanko Junyaku will be able to provide useful information to an even greater number of healthcare professionals to aid in the early diagnosis and treatment of influenza.

Influenza is an acute viral infection that reaches epidemic proportions every winter, as it affects many people. Complications associated with pneumonia in aged patients or with encephalopathy /encephalitis in children, especially, can easily become serious and while these patients tend to have a poor prognosis. In recent years, several anti-viral agents against influenza have been developed, and it has now become possible to reduce the risk of developing complications and serious aggravation by using the appropriate treatment in the early stages of the disease. Accordingly, an early diagnosis of influenza plays an important part in treatment of the disease.

By marketing the Kit, Sanko Junyaku, Eisai and Sekisui Medial seek to make contributions to increasing the benefits provided to influenza patients.
