Summary:

      There are many recent advances in insulin treatment of type 1 diabetes, however after a meal
      sugars are always a concern. There is a drug Exenatide (Byetta) which is FDA approved to
      treat people with type 2 diabetes which helps correct their glucoses (sugars) after meals.
      This study is going to test whether this drug can improve the after meal sugars in people
      with new onset type 1 diabetes. To test this you will be given a dose of exenatide (1.25 mcg)
      and long acting insulin or inulin alone before the boost. There is also a placebo group
      (healthy subjects) who do not get any medication before the boost. Insulin levels and other
      hormones that affect blood glucose as well as your sugar will be measured by a series of
      blood tests. The role exenatide as compared to insulin alone will be examined to prevent low
      blood sugars which might occur because of food staying longer in the stomach than usual or
      due to the suppression of a hormone called glucagon which increases blood sugar. If you
      qualify you will be given exenatide (Byetta 1.25 mcg) along with insulin or insulin alone.
      You and the researchers will not know which dose you are taking at any single visit. A total
      of 20 people in which some will be children aged 12- 18 years will participate, being
      diagnosed within 3 months of having been found to have type 1 diabetes.
