NCT06855615

Brief Summary

The goal of this cross-over study is to learn if thrice-daily (TDS) premixed human insulin (PHI) is as useful as basal-bolus (BB) therapy as an intensification treatment in people with poorly controlled type 2 diabetes mellitus (T2DM). The main questions it aims to answer are:

  • To determine the efficacy of TDS PHI compared to BB insulin regimen by measuring HbA1c changes over 12 weeks.
  • To determine the changes in fasting plasma glucose (FPG), the total daily dose (TDD) of insulin, weight changes, and hypoglycaemia rate, and to study the adherence rate to insulin injection between the two regimens over 12 weeks. Researchers will compare TDS-PHI to BB regimen to see if the glycemic control, TDD of insulin, weight gain, hypoglycemia and adherence rate are the same. Participants will:
  • take TDS-PHI or BB for 12 weeks and cross over to the other regimen for another 12 weeks
  • visit the clinic once every 4 weeks for checkups and tests
  • keep a diary of their self-monitoring of blood glucose (SMBG), insulin doses, hypoglycaemic symptoms and blood glucose readings, and the number of times they miss insulin injections.

  • Changes in TDD of insulin measured in units

    12 weeks

  • Changes in weight measured in kilograms

  • Changes in hypoglycemia rate as assessed by episodes per subject year

    12 weeks

  • Adherence to insulin injection as assessed by the frequency of missed doses per month

    12 weeks

Study Arms (2)

Group A (Mixtard® 30)

ACTIVE COMPARATOR

Participants start on TDS PHI (Mixtard® 30 TDS) and cross over to BB regimen (Insulatard® once daily plus thrice daily prandial Actrapid®) at 12 weeks (visit 4). The initial TDD of insulin equals the baseline TDD of the participants' original insulin regimen and is distributed in a 40:20:40 ratio (breakfast, lunch, and dinner).

Drug: Mixtard® 30 TDSDrug: Insulatard® once daily and thrice daily prandial Actrapid®

Group B (Insulatard® and Actrapid®)

ACTIVE COMPARATOR

Participants start on BB regimen (Insulatard® once daily plus thrice daily prandial Actrapid®) and cross over to TDS PHI (Mixtard® 30 TDS) at 12 weeks (visit 4). The initial TDD of insulin equals the baseline TDD of the participants' original insulin regimen and is split between Actrapid® and Insulatard® as 50 and 50 per cent, respectively. Actrapid® is further divided equally across the meals.

Drug: Mixtard® 30 TDSDrug: Insulatard® once daily and thrice daily prandial Actrapid®

Interventions

The clinical use of TDS premixed human insulin (PHI) is unclear. In contrast, biphasic insulin analogue given thrice daily is a well-proven, safe and suitable alternative to an intensified insulin regimen.

Group A (Mixtard® 30)Group B (Insulatard® and Actrapid®)

Basal bolus regimen is considered a physiological form of treatment and the standard of care in clinical practice but the multiple daily injections often lead to poor compliance.
