- HbA1c (glycosylated haemoglobin) above or equal to 7.5% by central laboratory analysis, with the aim of a median of 8.5%. When approximately 50% of the randomised subjects have an HbA1c above 8.5%, the remaining subjects randomised must have an HbA1c below or equal to 8.5% or when approximately 50% of the subjects randomised have an HbA1c below or equal to 8.5%, the remaining subjects randomised must have an HbA1c above 8.5%
