Sponsor Royal Free and University College Medical School
Start date April 2004
End date March 2006
Trial size 120 participants

Additional Information

Official title Randomised Double Blind Placebo Controlled Trial of Effects of Long Term Low Dose Oral Erythromycin Therapy in Patients With Chronic Obstructive Pulmonary Disease
Principal investigator Jadwiga A Wedzicha, MD
Description COPD is characterised by persisting airway inflammation which leads to a progressive and irreversible deterioration in lung function with the eventual development of respiratory symptoms which may become disabling. Periodic episodes of worsening symptoms or exacerbations are a major cause of additional morbidity, mortality and health care utilization. Currently available therapies have limited efficacy in reducing airway inflammation or preventing exacerbations. Macrolides such as erythromycin have been shown to have potent anti-inflammatory effects in in vitro experiments and in other lung conditions such as cystic fibrosis and bronchiectasis as well as in open label studies in COPD. We hypothesised that long term therapy with oral erythromycin would reduce airway inflammation and reduce the frequency of exacerbations in patients with COPD. If these properties are demonstrated this therapy can have potentially important benefits if effective in this condition.
