About

This trial is conducted in Africa. The aim of this clinical trial is to investigate the effect of 50 weeks of treatment with different intensified insulin administrations (all in combination with a fixed dose of metformin) on blood sugar control in subjects with type 2 diabetes inadequately controlled by oral anti-diabetic drugs (OADs).

403 participants in 2 patient groups

Detemir + Met
Active Comparator group
Description:
Individually adjusted insulin detemir (Detemir) was given subcutaneoulsy (s.c.) at bedtime in the thigh at an initial dose of 0.1 U/kg once daily for 50 weeks in combination with 1000-2000 mg/day metformin (Met). Pending evaluation of HbA1c every 3 months, individually adjusted insulin aspart was added to the insulin detemir treatment (up to three doses daily for maximum 36 weeks, injected s.c. \[under the skin\]) if treatment target of HbA1c below 7.0% was not reached.
Treatment:
Drug: insulin detemir
Drug: insulin aspart
Drug: metformin
BIAsp 30 + Met
Active Comparator group
Description:
Individually adjusted biphasic insulin aspart 30 (BIAsp 30) was given subcutaneously (s.c.) in the abdomen at dinner at an initial dose of 0.1 U/kg once daily for 50 weeks in combination with 1000-2000 mg/day metformin (Met). Pending evaluation of HbA1c every 3 months, the dose was intensified up to 3 doses daily, injected s.c. (under the skin) if treatment target of HbA1c below 7.0% was not reached.
Treatment:
Drug: biphasic insulin aspart 30
Drug: metformin
