Arakis and Vectura Announce Start of Phase IIb Trial of NVA237 for COPD

Tokyo, Japan/Little Chesterford, UK & Chippenham, UK – 17 October 2005: Arakis Ltd. (“Arakis”), a wholly-owned subsidiary of the biopharmaceutical company Sosei Co. Ltd. (“Sosei”; TSE Mothers Index: 4565), and Vectura Group plc (“Vectura”; LSE: VEC) announced today that their collaborative product, NVA237 (formerly AD 237), a novel inhaled once daily treatment for chronic obstructive pulmonary disease (COPD), has entered a Phase IIb multiple dose-ranging clinical trial. NVA237 is being developed and commercialised by Novartis both as a monotherapy and in combination with their once daily bronchodilator indacaterol (QAB149), under the terms of the agreement signed in April 2005.

The study is a randomised, double-blind, multi-centre, placebo-controlled trial designed to evaluate the efficacy, safety and dose response of NVA237 in patients diagnosed with COPD over a four week period.

COPD, the world’s fourth largest cause of death, is a chronic obstruction of the airways which is caused primarily by smoking. It is estimated that the disease is prevalent in 4% of the populations of the USA, Europe and Japan and that at least 15% of smokers will go on to develop the disease. Symptoms include chronic bronchitis and emphysema or both conditions, which slowly progress and eventually lead to a largely irreversible loss of lung function. The current market for COPD drug therapy is estimated to be worth $4 billion per annum and is predicted to grow to $10 billion by 2010.

Mr Shinichi Tamura, President & CEO of Sosei, said: "COPD is increasingly being recognised as a common and costly disease with high patient unmet need. The commencement of the Phase IIb trial represents a further important step in validating the clinical profile of NVA237, which we believe to be a very promising product with the potential to improve upon existing therapies”.

Dr Chris Blackwell, Chief Executive of Vectura, added: “The momentum for the clinical development of NVA237 also underpins the development of the NVA237/indacaterol combination product that we believe will play a major role in the future treatment of COPD. We are delighted to be able to announce the start of the Phase IIb programme”.
