Study summary

This trial is conducted in Asia, Europe and the United States of America (USA). The aim of this trial is to investigate the efficacy and safety of insulin degludec/liraglutide in insulin naïve subjects inadequately controlled with SU (sulphonylurea) alone or in combination with metformin. All subjects will continue their pre-trial SU treatment with or without metformin treatment without changing the frequency or dose throughout the trial.

Exclusion criteria

Exclusion Criteria:

  • Use of any drug (other than SU in monotherapy or in combination with metformin), which in the Investigators opinion could interfere with the blood glucose level (e.g. systemic corticosteroids)
  • Previous treatment with glucagon-like peptide-1 (GLP-1) receptor agonist (e.g. exenatide, liraglutide)

  • Subjects with a clinical significant, active (during the past 12 months) disease of the gastrointestinal, pulmonary, endocrinological (except for the Type 2 Diabetes Mellitus),neurological, genitourinary or haematological system that in the opinion of the Investigator,may confound the results of the trial or pose additional risk in administering trial product

What researchers measure

Primary outcomes

  1. Change in Glycosylated Haemoglobin (HbA1c)

    Change in HbA1c from baseline to 26 weeks.

    Time frame: Week 0, Week 26

Secondary outcomes

  1. Responders Achieving Pre-defined Target: HbA1c Below 7.0% (53 mmol/Mol)

    Percentage of subjects having HbA1c below 7% at week 26.

    Time frame: Week 26

  2. Responders Achieving Pre-defined Target: HbA1c Below or Equal to 6.5% (48 mmol/Mol)

    Percentage of subjects having HbA1c below 6.5% at week 26

    Time frame: Week 26

  3. Change From Baseline in Fasting Plasma Glucose (FPG)

    Change from baseline in FPG at week 26.

    Time frame: Week 0, week 26

  4. Change From Baseline in Body Weight

    Change from baseline in body weight at week 26.

    Time frame: Week 0, week 26

  5. Number of Treatment Emergent (Confirmed) Hypoglycaemic Episodes

    An event was treatment emergent if the onset of the episode occurs after the first administration of trial product and no later than 7 days after last trial product administration. Confirmed hypoglycaemic episodes were defined as hypoglycaemic episodes that were either severe or minor. Minor hypoglycaemic episodes were defined as: 1. An episode with symptoms consistent with hypoglycaemia and confirmed by blood glucose value \<2.8 mmol/L (50 mg/dL) or plasma glucose \<3.1 mmol/L (56 mg/dL) and which was handled by the subject himself/herself. 2. Any asymptomatic PG value \<3.1 mmol/L (56 mg/dL) or blood glucose value \<2.8 mmol/L (50 mg/dL). Severe hypoglycemia was defined as an episode requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions. Reported values are hypoglycemia event rate per 100 patient-years of exposure (PYE).

    Time frame: After 26 weeks of treatment

  6. Number of Adverse Events (AEs)

    An AE was any unfavourable and unintended sign (including an abnormal laboratory finding), symptom or disease temporally associated with the use of a product, whether or not considered related to the product. Reported values are hypoglycemia event rate per 100 PYE.

    Time frame: After 26 weeks of treatment
