Brief Summary

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

The aim of this study is to determine whether Super-Bolus is more effective in postprandial glycemic control than Normal-Bolus after the high glycemic index (H-GI) meal in children with type 1 diabetes (T1DM) treated with insulin pump (continuous subcutaneous insulin infusion, CSII).

Participants Investigators

Study Groups

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

Normal Bolus

Pre-breakfast insulin will be given as a Normal Bolus 15 minutes before the high-glycemic index meal (cornflakes and milk). The Normal Bolus will be calculated based on individual insulin-to-carbohydrate ratio (ICR).

Group Type ACTIVE_COMPARATOR

Insulin Glulisine

Intervention Type DRUG

A type of bolus insulin will be insulin glulisine if participant used insulin glulisine before entering the trial.

Insulin Aspart

Intervention Type DRUG

A type of bolus insulin will be insulin aspart if participant used insulin aspart before entering the trial.

Insulin Lispro

Intervention Type DRUG

A type of bolus insulin will be insulin lispro if participant used insulin lispro before entering the trial.

Super Bolus

Pre-breakfast insulin will be given as a Super Bolus 15 minutes before the high-glycemic index meal (cornflakes and milk). The Super Bolus will be calculated based on individual ICR increased to 150% and basal insulin will be suspended for 2 hours at the same time.

Group Type EXPERIMENTAL

Insulin Glulisine

Intervention Type DRUG

A type of bolus insulin will be insulin glulisine if participant used insulin glulisine before entering the trial.

Insulin Aspart

Intervention Type DRUG

A type of bolus insulin will be insulin aspart if participant used insulin aspart before entering the trial.

Insulin Lispro

Intervention Type DRUG
