Comparison of Exenatide vs. Biphasic Insulin Aspart 30 on Glucose Variability in Type 2 Diabetes
Study Details
Study Description
Brief Summary
This is a multi-centre, open-label, randomized, parallel trial to compare the effect of Exenatide versus Biphasic insulin Aspart 30 on glucose variability and inflammatory markers in type 2 diabetes mellitus (T2DM) patients inadequately controlled with metformin monotherapy.

Phase 4 |
Detailed Description
Studies have showed that fluctuations of glucose seem to have more deleterious effects than sustained hyperglycaemia in the development of diabetic complications. The present randomized controlled trial was designed with primary aim to evaluate glycaemic fluctuation in the comparison between twice-daily Exenatide and other treatment paradigm (e.g. insulin Aspart 30).
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Exenatide Exenatide (Colorless transparent liquid, comes in a prefilled pen.5ug/10ug, AstraZeneca) should be initiated, 60 minutes pre-breakfast and pre-supper, at 5ug twice a day for 4 weeks and then titrated up at 10ug twice a day until the completion of the study. |
Drug: Exenatide
Other Names:
|
| Active Comparator: Biphasic insulin Aspart 30 Biphasic insulin Aspart 30 (Colorless transparent liquid, 100u/mL, 3ml each, Novo Nordisk), subcutaneous injection, starting at a dose of 0.2-0.4 IU/kg, or 10～12 IU/d assigned in pre-breakfast and pre-supper in a 1:1 ratio. The adjustment of insulin dose is instructed to achieve an optimal balance between glycaemic control and risk of hypoglycaemia as dictated by best clinical practice, titrated to glucose targets of fasting plasma glucose (FPG) and pre-supper <7 mmol/L. |
Drug: Biphasic insulin Aspart 30
