Sosei Acquires Activus Pharma

Tokyo, Japan – 17 August 2010: Further to the announcement on 21 June 2010, Sosei Group Corporation (“Sosei”; TSE Mothers Index: 4565), is pleased to announce the completion of acquisition of Activus Pharma Ltd. (“Activus”).

Activus, based in Chiba, Japan, specializes in nano-particle processing technology that keeps compounds virtually free from contamination and increases their solubility, and therefore enables the development of injections, ophthalmic solutions and inhalations with poorly soluble compounds where high purity is required.

The technology can be expected to generate new development candidates for Sosei, and partnership with other pharmaceutical companies will allow Sosei to realize revenue from this technology in a relatively short period of time.
