Diabetes, Diabetes Mellitus, Type 2
Conditions
Brief summary
This trial is conducted in Europe, North America and the United States of America. The aim of this trial is to compare two different titration algorithms of insulin degludec/liraglutide.
Interventions
For subcutaneous (s.c., under the skin) injection, once daily. Subjects will be instructed to continue with the same dose of OADs (metformin alone or in combination with pioglitazone), as prior to the trial.

Eligibility
Inclusion criteria
* Type 2 diabetes mellitus * Male or female equal to or above 18 years of age * HbA1c (glycosylated haemoglobin) 7.0 - 10.0% \[53 mmol/mol - 86 mmol/mol\] (both inclusive), confirmed by the central laboratory * Stable daily treatment with metformin (above or equal to 1500 mg or max tolerated dose) with or without pioglitazone (above orequal to 30 mg) for at least 90 days prior to screening * Body Mass Index (BMI) below or equal to 40 kg/m\^2

Participants by arm
| Arm | Count |
|---|---|
| IDegLira (1WT) Subjects inadequately controlled on metformin either alone or in combination with pioglitazone were randomized in a 1:1 manner to receive IDegLira once daily. The subjects were stratified by their OAD treatment prior to entering the trial. The starting dose of IDegLira was 10 dose steps (10 units IDeg/0.36mg liraglutide), and the maximum dose was 50 dose steps (50units/1.8mg liraglutide) The daily dose for metformin was ≥ 1500mg or max tolerated dose and ≥ 30mg for pioglitazone. In the IDegLira once weekly titration group (1WT), the dose of IDegLira was adjusted based on the mean of 2 fasting SMPG values measured pre-breakfast in the morning of two consecutive days corresponding to one obtained on the day before titration and one obtained on titration day. | 210 |
