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

DRUGinsulin degludec/insulin aspart

Injected subcutaneously (under the skin) once daily with a meal. Dose was individually adjusted.

DRUGinsulin detemir

Injected subcutaneously (under the skin) once daily or twice daily. Dose was individually adjusted.

DRUGinsulin aspart
