This trial is conducted in Africa, Asia, Europe and the United States of America (USA).

The aim of this clinical trial is to compare NN5401 (insulin degludec/insulin aspart) with insulin glargine in patients with type 2 diabetes inadequately controlled with insulin and oral anti-diabetic drugs (OADs). Subjects continued their ongoing treatment with OADs in the trial.

Diabetes Mellitus, Type 2
Drug: insulin degludec/insulin aspart
Drug: insulin glargine

Primary Outcome Measures:
  • Change in Glycosylated Haemoglobin (HbA1c) [ Time Frame: Week 0, Week 26 ]
    Change from baseline in HbA1c after 26 weeks of treatment.

Secondary Outcome Measures:
  • Mean of 9-point Self Measured Plasma Glucose Profile (SMPG) [ Time Frame: Week 26 ]
    Mean of SMPG after 26 weeks of treatment. Plasma glucose measured: before breakfast, 90 minutes after start of breakfast, before lunch, 90 minutes after start of lunch, before dinner, 90 minutes after start of dinner, bedtime, at 4 am and before breakfast.
