Reporting Groups
  Description
Insulin Degludec Subjects received insulin degludec (IDeg) 100 units/mL once daily (OD) subcutaneously (S.C.; under the skin) in the thigh, upper arm, or the abdominal wall between dinner and bedtime. Subjects continued their pre-trial medication except for the basal insulin, which was replaced by investigational medicinal product (IMP; IDeg). The pre-trial bolus insulin was allowed and could be replaced with insulin aspart (IAsp) at the discretion of the investigator. For subjects previously receiving premixed/biphasic insulin the basal component was calculated and switched to IDeg OD, and the bolus insulin component to bolus insulin. For subjects previously receiving premixed/biphasic insulin twice daily (BID), the total basal component was calculated, reduced by 20- 30% and switched to IDeg OD, and the bolus component was calculated and switched to IAsp. The trial was event driven for with a realised observation period up to 33 months.
Insulin Glargine Subjects received insulin glargine (IGlar) 100 units/mL OD subcutaneously (S.C.; under the skin) in the thigh, upper arm, or the abdominal wall between dinner and bedtime. Subjects continued their pretrial medication except for the basal insulin, which was replaced by investigational medicinal product (IMP; IGlar). The pre-trial bolus insulin was allowed and could be replaced with IAsp at the discretion of the investigator. For subjects previously receiving premixed/biphasic insulin the basal component was calculated and switched to IGlar OD, and the bolus insulin component to bolus insulin. For subjects previously receiving premixed/biphasic insulin BID, the total basal component was calculated, reduced by 20- 30% and switched to IGlar OD, and the bolus component was calculated and switched to IAsp. The trial was event driven with a realised observation period up to 33 months.
