February 13, 2015 updated by: Novo Nordisk A/S
Comparison of the Efficacy on Glycaemic Control and Safety Profile of Biphasic Insulin Aspart 30 and Biphasic Human Insulin 30 Both in Combination With Metformin in Insulin-naïve Subjects With Type 2 Diabetes Mellitus Inadequately Controlled on Oral Antidiabetic Drugs (OADs) Therapy
This trial is conducted in Asia.
The aim of this clinical trial is to investigate the blood sugar lowering effect and the safety profile of biphasic insulin aspart 30 compared to biphasic human insulin 30, both in combination with metformin in Chinese insulin-naive subjects with type 2 diabetes when failing on oral antidiabetic drug (OAD) therapy.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: BIAsp 30
BIAsp 30 (biphasic insulin aspart 30) administered subcutaneously (under the skin) twice daily (before breakfast and dinner) + metformin.
Initial total daily dose of 0.3 U or IU/kg body weight followed by individual dose adjustment for BIAsp 30 was performed over the first 4 weeks (titration period) to achieve the pre-meal blood glucose target of 4.4-6.1 mmol/l.
The achieved dose was maintained for the last 2 weeks of treatment unless hypoglycaemia occurred.
|
The initial doses for BIAsp 30 twice-daily regimen will be recommended to start at a total daily dose of 0.3 U/kg body weight and to be equally divided (1/2:1/2) between pre-breakfast and pre-dinner
Metformin dose must remain the same as that used prior to the trial.
|
Experimental: BHI 30
BHI 30 (biphasic human insulin 30) administered subcutaneously (under the skin) twice daily (30 minutes before breakfast and dinner) + metformin.
Initial total daily dose of 0.3 U or IU/kg body weight followed by individual dose adjustment for BHI 30 was performed over the first 4 weeks (titration period) to achieve the pre-meal blood glucose target of 4.4-6.1 mmol/l.
The achieved dose was maintained for the last 2 weeks of treatment unless hypoglycaemia occurred.
|
Metformin dose must remain the same as that used prior to the trial.
The initial doses for BHI 30 twice-daily regimen will be recommended to start at a total daily dose of 0.3 IU/kg body weight and to be divided in the ratio of 2/3:1/3 between pre-breakfast and pre-dinner

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in IAUC (Incremental Area Under the Curve) for Postprandial Glucose (0-4 Hours) Over 3 Main Meals
Time Frame: Week 0, week 6
|
The blood glucose profiles were monitored by CGMS (Continuous Glucose Monitoring System) for 72 hours at baseline (week 0) and end of treatment (week 6).
IAUC was calculated using the trapezoidal method.
The arithmetic mean of IAUC (3 meal-specific incremental areas) of day 1 and day 2 was used as the value of IAUC for each CGMS period

IAUC (0-4 hours) after each meal at 6 weeks and change in IAUC (0-4 hours) from baseline (week 0) after each meal were to be assessed.

|
Change in MAGE (Mean Amplitude of Glycaemic Excursions) Assessed by CGMS
Time Frame: Week 0, Week 6
|
MAGE is a parameter to monitor the intraday blood glucose excursions.
It was calculated using CGMS data and as the arithmetic mean of glycaemic excursion with the criterion that both segments (ascending and descending parts) of the glycaemic excursion exceed of the value of one standard deviation of respective 24-hour blood glucose value.
The direction of calculation (peak-to-nadir or nadir-to-peak) was established by the direction of the first excursion.
The arithmetic mean of the glycaemic excursion of day 1 and day 2 was the value of MAGE for each CGMS

Duration of Hypoglycaemic Events Based on CGMS
Time Frame: 72-hour monitoring period at Week 0 and Week 6
|
The CGMS device recorded blood glucose levels every 10 seconds then stored a smoothed average over 5 minutes.
The range of blood glucose detection was 2.2-22 mmol/l.
Hypoglycaemia was defined as blood glucose readings below 3.5 mmol/l or below 2.5 mmol/l, respectively.
The duration of the hypoglycaemic episodes was quantified by accumulating the total time the CGMS profiles stays below the defined threshold (i.e.
below 3.5 mmol/l or below 2.5 mmol/l, respectively).
|
72-hour monitoring period at Week 0 and Week 6
|
Hypoglycaemia Based on Self-reported Episodes
Time Frame: Weeks 0-6
|
Total number of hypoglycaemic episodes occurring in the trial after baseline (week 0) until the end of treatment (week 6).
Hypoglycaemic episodes are classified as major, minor or symptoms only: Major if the subject was unable to treat her/himself; minor if subject was able to treat her/himself and self monitored blood glucose (SMBG) was below 2.8 mmol/L; symptoms only if subject was able to treat her/himself and with no blood glucose measurement or SMBG higher than or equal to 2.8 mmol/L.
