Sosei and Vectura Announce Start of Phase II Studies of QVA149 for the Treatment of COPD

Sosei and Vectura Announce Start of Phase II Studies of QVA149 for the Treatment of COPD Tokyo, Japan and Chippenham, UK – 15 November 2007 : Sosei Group Corporation (“Sosei”; TSE Mothers Index : 4565) and Vectura Group plc (“Vectura”; LSE: VEC) announce the start, by Novartis, of a Phase II safety study of QVA149 for the treatment of chronic obstructive pulmonary disease (COPD). QVA149 is a combination of NVA237, a once-daily long-acting muscarinic antagoni st (LAMA) and indacaterol, a once-daily long-acting beta-2 agonist (LABA). The randomised, double-blind, placebo-controlled, multi-centre study will determine the effect of QVA149 and indacaterol on mean 24-hour heart rate in patients with moderate to severe COPD. NVA237 was licensed to Novartis by Sosei and Vectura in 2005 in a deal in which the two companies could receive up to US$ 375 m illion in milestones as well as royalties on product sales. Indacaterol was discovered by No vartis and is currently in Phase III trials for COPD. NDA submissions have been projected for 2010. Mr Shinichi Tamura, President & CEO of Sose i, said: “I am delighted that QVA149 has now entered Phase II clinical developmen t. This once-daily LAMA/LABA combination has the potential to be a best in class treatment.” Dr Chris Blackwell, Chief Executive of Ve ctura added: “Chronic respiratory diseases like COPD are often sub-optima lly treated, and patients don’t always receive effective therapies. The market for COPD therapy is predicted to double in size to $11 billion by 2011. The progress Novartis is making wi th both NVA237 and QVA 149 is therefore of interest to many.” - Ends - Enquiries: Sosei Group Corporation Ichiban-cho FS Bldg., 8 Ichiban-cho, Chiyoda-ku, Tokyo 102-0082 Japan Hiroki MAEKAWA, Representative Executive Officer, E-mail: [email protected] Tel: +81-3-5210-3399 Sosei R&D Ltd Chesterford Research Park, Saffron Walden, CB10 1XL England John DAFFURN, SVP Corporate Development, E-mail: [email protected] Tel: +44 (0)1799 532 350 The Trout Group Thomas Fechtner Tel: +1 646-378-2915 Brandon Lewis Tel: +1 646-378-2931 Vectura Group plc Tel: + 44 (0) 1249 667700 Chris Blackwell, Chief Executive Anne Hyland, Chief Financial Officer Julia Wilson, Director of Investor Relations & Corporate Communications Financial Dynamics Tel: + 44 (0) 207 831 3113 David Yates Notes for Editors: About the NVA237 licence agreement with Novartis Sosei and its co-development partner Vectur a Group plc concluded a global development and commercialisation agreement with Novartis in April 2005 for their collaborative product NVA237. Novartis is responsible for developing and commercializing NVA237 both as a monotherapy and in combination with indacaterol, its once daily, long acting beta 2 agonist, as QVA149. Under the terms of the agreement, Sosei and Vectura have already received $15 million each and will receive up to $172.5 million each for achieving pre-agreed clinical, regulatory and commercialisation targets for both the monotherapy and combination product. These potential milestones thus total up to $375 million. In addition, royalties on product sales will be paid for the monotherapy and the combination product. If a third combination product is developed by Novartis, using NVA237, further milestones and royalties may be payable. About COPD COPD is a chronic obstruction of the airways which in the developed world is caused primarily by smoking. Symptoms include chronic bronchitis and/or emphysema which slowly progress and eventually lead to a largely irreversible loss of l ung function. COPD is currently the fourth most common cause of death and by 2020 is predicted to become the third most common cause of death and the fourth most important disability causing illness. The total financial burden of lung disease in Europe amounts to nearly €102 billion with COPD contributing almost one half of this figure. Around three-quarters of patients with advanced COPD are unable to perform normal everyday activities. The current market for COPD drug therapy is estimated to be worth around $6 billion per annum and is forecast to grow to $11 billion by 2011 as a result of increasing diagnosis and treatment and the growth of high value new products.
