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

The aim of this trial is to compare the efficacy and safety of NN5401 (insulin degludec/insulin aspart (IDegAsp)) with insulin glargine (IGlar), both as add-on to subject's ongoing treatment with metformin + at least one OAD (oral anti-diabetic drug).

Main period is registered internally at Novo Nordisk as NN5401-3590 while the extension period is registered as NN5401-3726.

Primary Outcome Measures:
  • Main Trial (Primary Endpoint): Change in Glycosylated Haemoglobin (HbA1c) after 26 Weeks of Treatment [ Time Frame: Week 0, Week 26 ] [ Designated as safety issue: No ]
  • Extension Trial (Primary Endpoint): Rate of Confirmed Hypoglycaemic Episodes [ Time Frame: Week 0 to Week 52+ 7 days follow up ] [ Designated as safety issue: No ]
  • Extension Trial (Primary Endpoint): Rate of Nocturnal Confirmed Hypoglycaemic Episodes [ Time Frame: Week 0 to Week 52 + 7 days follow up ] [ Designated as safety issue: No ]
  • Extension Trial (Primary Endpoint): Rate of Treatment Emergent Adverse Events (AEs) [ Time Frame: Week 0 to Week 52 + 7 days follow up ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Extension Trial (Secondary Endpoint): Change in Glycosylated Haemoglobin (HbA1c) after 52 Weeks of Treatment [ Time Frame: Week 0, Week 52 ] [ Designated as safety issue: No ]
  • Main Trial (Secondary Endpoint): Mean of 9-point Self Measured Plasma Glucose Profile (SMPG) at Week 26 [ Time Frame: Week 26 ] [ Designated as safety issue: No ]
