Diabetes, Diabetes Mellitus, Type 2
Conditions
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.
Interventions
Insulin degludec/insulin aspart injected subcutaneously (under the skin) once daily. Dose individually adjusted.

Participants by arm
| Arm | Count |
|---|---|
| IDegAsp Simple Insulin degludec/insulin aspart (IDegAsp) was given once daily (OD) subcutaneously (3-4 days intervals between doses) with pre-trial metformin according to simple titration algorithm: self-titration was performed twice weekly based on pre-breakfast self-measured plasma glucose (SMPG) value measured on the day of insulin titration. | 136 |
| IDegAsp Step Wise Insulin degludec/insulin aspart (IDegAsp) was given once daily (OD) subcutaneously (at least 5 days intervals between doses) with pre-trial metformin according to step wise titration algorithm: self-titration was performed once weekly based on the lowest value of three pre-breakfast SMPG values measured on three consecutive days, the two days prior to and on the day of insulin titration. | 140 |
