Summary

In recent years, diabetes has emerged as one of the most significant co-diseases that many Cystic Fibrosis (CF) patients develop. Type 1 and Type 2 diabetes results when either the body does not make enough insulin or the body does not respond correctly to this insulin. Insulin is a hormone which is made by cells in the pancreas and helps carry glucose (sugar) from the food we eat to the cells of the body for energy. While cystic fibrosis related diabetes (CFRD) has many features similar to both Type 1 and Type 2 diabetes, it is very different; therefore, treatment and care of CFRD is not the same.

The purpose of this research study is to examine and understand the various mechanisms that contribute to CFRD and gain a better understanding of potential means to treat CFRD. The primary objective is to determine effectiveness of chronic incretin-based therapy vs. placebo on insulin secretion in CF patients with indeterminate glucose tolerance, impaired glucose tolerance, or CFRD.

Conditions

Interventions

DRUG

Sitagliptin

The GPA test as described in the primary outcome section will be performed at baseline and after 6 months of therapy in the Sitagliptin and placebo arms. Furthermore, evaluation of endogenous GLP-1 levels will be assessed by a mixed meal tolerance test compared at baseline and 6 months.

DRUG

Placebo

The GPA test as described in the primary outcome section will be performed at baseline and after 6 months of therapy in the Sitagliptin and placebo arms. Furthermore, evaluation of endogenous GLP-1 levels will be assessed by a mixed meal tolerance test compared at baseline and 6 months.
