Clinical Trial Results:
A 26-week open label, randomised, 2-armed, parallel group, multi-centre trial investigating efficacy and safety of insulin detemir versus insulin Neutral Protamine Hagedorn in combination with the maximum tolerated dose of metformin and diet/exercise on glycaemic control in children and adolescents with type 2 diabetes insufficiently controlled on the maximum tolerated dose of metformin ± other oral antidiabetic drug(s) ± basal insulin

General information about the trial
|
|||
Main objective of the trial |
To compare the efficacy of insulin detemir in combination with metformin and diet/exercise versus insulin neutral protamine hagedorn (NPH) in combination with the maximum tolerated dose (MTD) of metformin and diet/exercise in controlling glycaemia, after 26 weeks of treatment, in children and adolescents (aged 10–17 years) with type 2 diabetes, who are insufficiently treated with the MTD of metformin ± other OAD(s) ± basal insulin.
|
||

Arm description |
Subjects were treated with insulin detemir 100 U/mL administered subcutaneously in the thigh region once or twice daily for a period of 26 weeks. All subjects continued treatment with metformin on their pre-study dose(s) throughout the trial. The diet/exercise intervention was performed through changes in eating and activity behaviours. | |||||||||||||||||||||

Dosage and administration details |
For insulin naïve subjects, insulin detemir was initiated at a dose of 0.1−0.2 U/kg with a maximum dose of 10 U at the investigators discretion. Subjects who were already on basal insulin were switched to insulin detemir unit-to-unit once or twice daily, depending on previous injection frequency. Subjects were dosed according to individual requirements during the trial period.
