Mr Shinichi Tamura, President & CEO of Sosei, said: "I am delighted that Novartis has confirmed the progression of QVA149 into clinical development and that both QVA149 and NVA237 are expected to file in 2010. Both products will add breadth to the options available for the treatment of COPD, the prevalence of which continues to rise.”
