Research into respiratory disease continues to have a high profile due to unmet needs and the large patient populations.

Asthma is one of the top 15 most important disorders in terms of global years lived with disability and affecting over 300 million people of all ages in all parts of the world. It causes about 250,000 deaths each year. Prevalence shows an increase year by year, especially in developing countries and children.

COPD is expected to be the 3rd leading cause of death worldwide and by 2020 and the 5th leading cause of years lost through early mortality or disability. Cystic fibrosis is affecting over 70,000 people worldwide. This is about 1 of 2500 live births in Caucasians. The Lung is affected in 90% of patients surviving the neonatal period and end-stage lung disease is the principal cause of death.

Allergic rhinitis and conjunctivitis affects over 400 million people around the world, which to a large extent remain underdiagnosed and undertreated. Children are especially affected.

Idiopathic Pulmonary Fibrosis has approximately 30,000–35,000 new patients diagnosed each year.
