Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a randomized, cross-over study. The aim of this study is to compare the post-prandial glycaemic variability after pure protein meal following with an administration of square-wave bolus of meal-insulin or without any meal-insulin bolus on the other day.

Prolonged post-prandial glycaemic variability will be identified using the self-monitoring of blood glucose (10-point curve) and CGMS.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The square-wave bolus (for meals rich in fat and/or protein) is evenly delivered over several hours as programmed by the patient. The required insulin dose will be calculated based on patient's insulin-exchange ratio. Pure protein meal will be given 3 hours after a first breakfast.

To provide the minimal impact of the previous breakfast, all patients will receive up to 120 kcal of carbohydrates and \<100 kcal from protein and fat for the first breakfast (without any extended bolus) Patients receive a standardized pure protein meal at a second breakfast time. Meal insulin will be given as a square bolus or no meal -insulin will be given at all. The 5h post-meal glucose excursions will be recorded by self-blood glucose measurements (SMBG) (every 30 minutes) and continuous glucose monitoring system (CGMS). The intervention is taking part under in-patient clinical conditions.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

group A

On the first study day, insulin bolus was not given before a standardized pure protein meal. On the second day, pre-breakfast insulin was given as a square-wave bolus before the same standardized pure protein meal.

The fat-protein-insulin ratio on both study days were identical to the patient's ratio when entering trial.

Kind of study bolus insulin will be a rapid-acting insulin analog same as previously used by the participant (before entering the trial) - insulin aspart, insulin lispro or insulin glulisine

Insulin glulisine

Intervention Type DRUG

A kind of study bolus insulin will be insulin aspart if participant used insulin aspart before entering the trial

Insulin aspart

Intervention Type DRUG

A kind of study bolus insulin will be insulin lispro if participant used insulin lispro before entering the trial

Insulin lispro

Intervention Type DRUG

A kind of study bolus insulin will be insulin lispro if participant used insulin lispro before entering the trial

group B

On the first study day, pre-breakfast insulin was given as a square-wave bolus before a standardized pure protein meal. On the second day, insulin bolus was not given before the same standardized pure protein meal.

The fat-protein-insulin ratio on both study days were identical to the patient's ratio when entering trial.
