Recruitment details

First patient enrolled 24 November 2009. Last patient completed 18 August 2010. Study conducted at 79 centres in 6 countries (Bulgaria, Czech Republic, Hungary, Poland, Romania, Slovakia).

Pre-assignment details

3- or 4-week run-in period on budesonide/formoterol twice daily to stabilise patients on maintenance therapy before randomisation. Patients already on budesonide/formoterol required a 3-week run-in period and patients on ICS as monotherapy or in combination with any long-acting bronchodilator required a 4-week run-in period.
