Vernalis Starts Phase IIa Trial of V3381 in Diabetic Neuropathic Pain

03 August 2006

Vernalis plc (LSE: VER, Nasdaq: VNLS) today announced that it has commenced enrolment into a Phase IIa trial of V3381 in patients with neuropathic pain resulting from long-standing diabetes. V3381 is the Company’s novel drug candidate that is believed to have dual mechanisms of action targeting both the central and peripheral nervous systems and is a programme where Vernalis has world-wide rights.

The randomised, double-blind, crossover Phase IIa study is designed to assess safety, pharmacokinetics and preliminary efficacy of repeat dosing of V3381, with efficacy being assessed on a numerical point pain rating scale recorded using daily diaries. The trial is being conducted in the United States and Canada , will include approximately 30 patients and is planned to complete in 12 months.

V3381 was originally licensed from Chiesi and has previously undergone evaluation in pre-clinical and Phase I clinical studies, including two proof-of-concept studies in a human model of neuropathic pain.

“Neuropathic pain causes enormous suffering and we are hopeful that V3381 may ultimately prove to be an effective treatment for this challenging condition,” said Simon Sturge , CEO of Vernalis. "We are building our franchise in pain management and are pleased that we have progressed V3381 to the next stage in its development.”

Neuropathic pain resulting from diabetes is a poorly treated condition that affects 4 million patients in the US and Europe . According to the National Institute of Diabetes & Digestive & Kidney Diseases, approximately half of those with diabetes develop some form of neuropathy, highlighting the growing need for drug treatment in this condition. The global trends towards obesity are furthering the incidence of diabetes and hence the problem of neuropathic pain is on the increase.

Notes to Editors
Neuropathic pain is a chronic form of pain related to damage to nerves and their signalling processes, and unlike other forms of pain, is generally non-responsive to current analgesics, does not diminish over time and can increase in both intensity and area. This type of pain occurs in later stages of diabetes, post-herpetic neuralgia (shingles), side effects of chemotherapy, trigeminal (facial) neuralgia, HIV infection, spinal cord injuries and other nerve injuries (eg. amputation).
