Brief Summary:
This trial is conducted in Asia and North America. The aim of this trial is to compare the efficacy and safety of insulin degludec/insulin aspart (IDegAsp) once daily in insulin-naïve subjects with type 2 diabetes mellitus when using two different titration algorithms (dose individually adjusted) as add-on to subject's ongoing treatment with metformin.

Condition or disease Intervention/treatment Phase

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

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


Secondary Outcome Measures :
  1. Change in Fasting Plasma Glucose (FPG) [ Time Frame: Week 0, week 26 ]
    Change from baseline in FPG after 26 weeks of treatment.

  2. Rate of Treatment Emergent Adverse Events (AEs) [ Time Frame: Week 0 to Week 26 + 7 days follow up ]
    Corresponds to rate of AEs per 100 patient years of exposure. Severity assessed by investigator. Mild: no or transient symptoms, no interference with subject's daily activities. Moderate: marked symptoms, moderate interference with subject's daily activities. Severe: considerable interference with subject's daily activities, unacceptable. Serious AE: AE that at any dose results in any of the following: death, a life-threatening experience, in-subject hospitalization/prolongation of existing hospitalisation, persistent/significant disability/incapacity/congenital anomaly/birth defect.

  3. Rate of Confirmed Hypoglycaemic Episodes [ Time Frame: Week 0 to Week 26 + 7 days follow up ]
    Rate of confirmed hypoglycaemic episodes per 100 patient years of exposure (PYE). Confirmed hypoglycaemic episodes consisted of severe hypoglycaemia as well as minor hypoglycaemic episodes. Severe hypoglycaemic episodes were defined as requiring assistance to administer carbohydrate, glucagon, or other resuscitative actions. Minor hypoglycaemic episodes were defined as able to treat her/himself and plasma glucose below 3.1 mmol/L.

  4. Rate of Nocturnal Confirmed Hypoglycaemic Episodes [ Time Frame: Week 0 to Week 26 + 7 days follow up ]
    Rate of nocturnal confirmed hypoglycaemic episodes per 100 patient years of exposure (PYE). Confirmed hypoglycaemic episodes consisted of severe hypoglycaemia as well as minor hypoglycaemic episodes. Severe hypoglycaemic episodes were defined as requiring assistance to administer carbohydrate, glucagon, or other resuscitative actions. Minor hypoglycaemic episodes were defined as able to treat her/himself and plasma glucose below 3.1 mmol/L. Nocturnal hypoglycaemic episodes were defined as occurring between 00:01 and 05:59 a.m.
