The dose(s) should as minimum be as stated: -Insulin secretagogue (sulfonylurea or glinide): Minimum half of the daily maximal dose according to local labelling -Metformin: alone or in combination (including fixed combination): Maximum tolerated dose - alfa-glucosidase-inhibitors: Minimum half of the daily maximal dose or maximum tolerated dose -DPP-4 (dipeptyl peptidase 4) inhibitor: According to local labelling
• HbA1c 7.0-10.0 % (both inclusive) by central laboratory analysis
• Body Mass Index (BMI) no higher than 35.0 kg/m^2
