Diabetes, Diabetes Mellitus, Type 1
Conditions
Brief summary
This trial is conducted in Europe, Oceania, and the United States of America (USA). The aim of this clinical trial is to compare NN5401 (insulin degludec/insulin aspart (IDegAsp)) with insulin detemir (IDet) plus insulin aspart in patients with type 1 diabetes (main period) followed by the extension period comparing the long-term safety of NN5401 plus insulin aspart with insulin detemir plus insulin aspart. The main period is registered internally at Novo Nordisk as NN5401-3594 while the extension period is registered as NN5401-3645.
Interventions
Injected subcutaneously (under the skin) once daily with a meal. Dose was individually adjusted.
Injected subcutaneously (under the skin) once daily or twice daily. Dose was individually adjusted.
Injected subcutaneously (under the skin) at the remaining meals. Dose was individually adjusted.
