NCT00652288

Brief Summary

The aim of this study is to evaluate the variations in pharmacokinetic and pharmacodynamic properties of rapid-acting insulin analogs when given as a bolus by subcutaneous insulin infusion pump as typically encountered in the care of children with type 1 diabetes. The specific factors under investigation are:

  • the effects of puberty
  • type of insulin analog
  • site of catheter insertion
  • and age of catheter
