Use of Terbutaline or a Reduction in Basal Insulin in the Prevention of

Status Completed

Clinical Trial Summary

The investigators hypothesize that the use of an oral dose of Terbutaline or a 20% basal reduction will be able to prevent nocturnal hypoglycemia after an afternoon exercise session. This is a randomized three period cross-over study including treatment with Terbutaline, a 20% basal reduction for six hours, or no treatment (control).

Clinical Trial Description

In this study, a minimum of 16 youth with type 1 diabetes will be recruited. All subjects must have been diagnosed with type 1 diabetes for at least one year and on an insulin pump for at least one month. Subjects are between the ages of 10 and 17 years, inclusive, have an HbA1c less than 10.0% and normal thyroid function. Subjects can not have had a severe hypoglycemic episode in the last three months, any other illness or treatment that may affect the wearing of a continuous glucose monitor or the completion of the study as determined by the investigator. Subjects may not use drugs containing pseudoephedrine within 48 hours of the study visits.

This study consists of three overnight visits at the Clinical Translational Research Center. Meals eaten during the study will be consistent for each of the three visits.

Subjects will participate in a standardized afternoon exercise session on a treadmill as has been done in previous Diabetes Research in Children Network studies. Exercise will begin at 4pm and must be completed by 6pm. Dinner will be eaten at the end of the exercise.

At 9pm, treatment will be given as determined by the randomization group the subject is assigned to. The treatment includes either an oral dose of 2.5mg Terbutaline, a 20% basal reduction for six hours or no treatment as the control. Blood glucose levels will be measured every 30 minutes until 6am. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
