Diabetes, Diabetes Mellitus, Type 2
Conditions
Brief summary
This trial is conducted in Japan. The aim of this clinical trial is to investigate the safety (with emphasis on hypoglycaemia) after switching from long-acting insulin analogue/intermediate-acting insulin or pre-mixed insulin/pre-mixed insulin analogue on a twice daily regimen to NN5401 (SIAC, insulin degludec/insulin aspart) on a twice daily regimen in subjects with type 2 diabetes mellitus.
Interventions
The insulin NN5401 (insulin degludec/insulin aspart) injected subcutaneously immediately before breakfast and dinner.
The insulin (biphasic insulin aspart 30) injected subcutaneously immediately before breakfast and dinner.

Secondary

|---|---|---|
| Electrocardiogram (ECG) Worsening | Week 0, Week 6 | The number of subjects having an electrocardiogram (ECG) that changed from 'Normal' or 'Abnormal, not clinically significant' to 'Abnormal, clinically significant'. 'Abnormal, Clinically significant' is an abnormality that suggests a disease and/or organ toxicity and is of a severity, which requires active management. |
| Number of Treatment Emergent Adverse Events (AEs) | Week 0 to Week 6 + 5 days follow up | Corresponds to number of adverse events. 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. |
| Systolic BP (Blood Pressure) | Week 0, Week 6. | Values at baseline (Week 0) and at Week 6 |
