Conditions

Diabetes Mellitus, Type 1

Brief summary

Patients will continue to use their current insulin pump for this study. Patients will receive insulin lispro and insulin aspart during this study. One medication will be taken for 12 weeks and then the other medication for 12 weeks. Neither the patient nor the study doctor will know which medication is being taken at any time. The order in which the two medications are taken will be determined by chance.
