Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine the effects of sitagliptin on glucose variability both after meals and overnight in adult patients with type 1 diabetes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Improved post prandial glucose control with multiple daily injections of insulin in the DCCT study demonstrated significant reductions in microvascular complication. Similar to type 2 diabetes, patients with type 1 diabetes have a paradoxical increase in glucagon after meals which contribute to worsening post prandial glucose control. This proposed study is designed to determine if altering the glucagon axis by giving sitagliptin can improve glucose control in patients with type 1 diabetes.
