Comparison of Premixed Insulin With Basal-plus Insulin in Type 2 Diabetes Patients

Phase 4
Completed
Conditions
Diabetes
Interventions
Drug: switch twice-daily insulin
Registration Number
NCT02219750
Lead Sponsor
Mackay Memorial Hospital
Brief Summary

Comparison of efficacy and safety of different insulin regimens between basal bolus and premixed insulin in poorly controlled type 2 diabetes

Detailed Description

This is a 24-week, prospective, open-label, randomized, parallel-group study conducted in approximately 140 patients with type 2 diabetes from Mackay Memorial Hospitals and Mackay Memorial Hospital Taitung branch. After enrollment, eligible patients will be randomized in a 1:1 ratio to either Basal-plus therapy(BPT) or Preprandial premix therapy(PPT). The effectiveness of advancing insulin therapy will be assessed at baseline and at 12 and 24 weeks after initiation of study prescription. The safety will be followed during the 24-week study period. All study procedure will be conducted after obtaining informed consent.

GroupInterventionDescription
Preprandial premix therapyswitch twice-daily insulinswitch twice-daily insulin Preprandial premix therapy mean that transition of advance insulin based on the basal insulin daily total dose at study entry divided into two equal dose of preprandial NovoMix 30. Patient discontinued all pre-study oral antidiabetic drug(OAD), including sulfonylureas, glinides, Thiazolidinedione(TZD) and Dipeptidyl peptidase-4(DPP-4) inhibitor but left metformin alone
Basal-plus insulinswitch twice-daily insulinswitch twice-daily insulin Basal-plus insulin consisted of continued previous basal insulin and add-on once-daily insulin aspart(NovoRapid) before breakfast. The starting dose of insulin aspart was 4 unit(U) before breakfast and continued under previous basal insulin dose.
