Do you have asthma? Asthma is the inflammation and narrowing of the airways in the lungs that makes breathing difficult for millions of people in the UK. The main symptoms of asthma include wheezing, coughing, chest tightness and shortness of breath. The severity of asthma symptoms can vary. Asthma can be well controlled in most people most of the time, although some people may have more persistent problems.

If you have been diagnosed with asthma for at least 12 months and you are 18 – 65 years of age, you might be eligible for a clinical trial.
