  Purpose

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

The aim of the trial is to compare the efficacy and safety of two different titration algorithms for insulin degludec/insulin aspart (IDeg/IAsp) in subjects with type 2 diabetes mellitus previously treated with insulin glargine.

Primary Outcome Measures:
  • Change From Baseline in HbA1c (Glycosylated Haemoglobin) (%) [ Time Frame: Week 0, Week 26 ] [ Designated as safety issue: No ]
    Change from baseline in HbA1c after 26 weeks of treatment.


Secondary Outcome Measures:
  • Change From Baseline in Fasting Plasma Glucose (FPG) [ Time Frame: Week 0, Week 26 ] [ Designated as safety issue: No ]
    Change from baseline in fasting plasma glucose (FPG) after 26 weeks of treatment

  • Subjects With HbA1c Below 7.0% [ Time Frame: Week 26 ] [ Designated as safety issue: No ]
    Number of subjects with HbA1c below 7% after 26 weeks of treatment.

  • Percentage of Subjects With HbA1c Below 7.0% Without Confirmed Hypoglycaemia [ Time Frame: Week 26 ] [ Designated as safety issue: No ]
    Percentage of subjects with HbA1c below 7% without confirmed hypoglycaemic episodes after 26 weeks of treatment.

  • Incidence of Treatment Emergent Adverse Events (TEAEs) [ Time Frame: Weeks 0-28 ] [ Designated as safety issue: No ]
    A Treatment Emergent Adverse Event (TEAE) was defined as an event that had onset date on or after the first day of exposure to randomised treatment and no later than 7 days after the last day of randomised treatment.

  • Number of Treatment Emergent Confirmed Hypoglycaemic Episodes [ Time Frame: Weeks 0-27 ] [ Designated as safety issue: No ]
    Confirmed hypoglycaemic episodes consisted of episodes of severe hypoglycaemia and 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.

  • Number of Treatment Emergent Confirmed Hypoglycaemic Episodes in the Maintenance Period [ Time Frame: From week 16 to end of trial including follow-up (week 27) ] [ Designated as safety issue: No ]
    Confirmed hypoglycaemic episodes in the maintenance period (from Week 16 to the end of the trial including follow-up [Week 27]) consisted of episodes of severe hypoglycaemia and 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.

  • Number of Treatment Emergent Nocturnal (00:01-05:59) Confirmed Hypoglycaemic Episodes [ Time Frame: Weeks 0-27 ] [ Designated as safety issue: No ]
    Confirmed hypoglycaemic episodes consisted of episodes of severe hypoglycaemia and 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 am.
