The primary objective is to establish the mean percentage of change in the insulin-to-carbohydrate ratio due to pramlintide treatment once a maximum tolerated dose or 6 mcg before each meal is reached. The secondary objective is to establish which insulin bolus wave form is associated with the lowest post-bolus without hypoglycemia in subjects treated with maximum pramlintide dosage.

Primary Outcome Measures:
  • The mean ICR from Vist 3a-e and 4a-e will be compared. Percentage reduction of ICR will be calculated. From these the mean ICR will be calculated. [ Time Frame: 12-10-07 ]

Secondary Outcome Measures:
  • The mean post-meal glucose from the four hour period after beginning a meal will be averaged for each bolus wave form. Then the three wave form mean glucose results will be compared. [ Time Frame: 12-10-07 ]

Estimated Enrollment: 12

Detailed Description:

Pramlintide. an amylinomimetic, is effective in reducing post-meal glucose by non-insulin means. As such, when patients requiring insulin treatment are treated with pramlintide, the bolus insulin does must be reduced. Current recommendations suggest a 50% reduction but in our experience and that of a recent study this appears excessive. By using continuous glucose monitoring(CGM) to guide pre-meal insulin treatment, we will determine the percentage reduction in meal time insulin bolus comparing pre-pramlintide to maximum pramlintide treatment. We anticipate that the reduction in bolus dosage will be about 25%. In addition, the secondary aim of this study is to determine which bolus pattern, standard, square or dual wave, provides the best post-meal glucose control with pramlintide therapy.
