5/29/2007 10:49:30 AM

TOKYO, May 29 /PRNewswire-FirstCall/ -- Sosei Group Corporation , a biopharmaceutical company, today announces that its collaborative project SD118, which is under development for the treatment of neuropathic pain, has commenced Phase I clinical trials.

SD118 is being jointly developed with NeuroDiscovery Ltd and its wholly owned subsidiary NeuroSolutions Ltd under a Collaboration Agreement concluded in June 2006. SD118 was previously under investigation in Japan for a different indication and now, following re-profiling and evaluation in experimental animal models, has demonstrated its potential as a new oral therapy for neuropathic pain.

The study is a double blind, placebo controlled, single dose, sequential group, dose escalation trial in healthy male volunteers to assess the safety, tolerability and pharmacokinetic profile of SD118 administered as an oral capsule. The study, involving some 40 subjects, will be conducted in a single centre in the UK under a CTA regulatory approval.

Mr Shinichi Tamura, President & CEO of Sosei, said: "I am delighted that SD118 has now moved forward into clinical development. This project has the potential to provide a valuable addition to currently available therapies in an area of notable unmet medical need"

About Neuropathic Pain

Neuropathic pain is associated with peripheral or central nervous system injury. It is often described as "burning" or "shooting" in nature and can be continuous or paroxysmal. It is estimated that up to 5% of the general population of the USA, Europe and Japan are affected by neuropathic conditions including diabetic neuropathic pain and post-herpatic neuralgia.

The disease is predominantly treated at present with a variety of anticonvulsant, antidepressant and analgesic drugs but many patients fail to respond adequately to these agents. Consequently neuropathic pain is recognised as an area of significant unmet medical need. The global market value for neuropathic pain treatments is currently estimated at $2.1Bn and is predicted to rise to $5.5Bn by 2015.
