The Contribution of Incretin Hormones to the Amelioration of Glucose Metabolism After Roux-en-Y Gastric Bypass

Early Phase 1
Completed
Conditions
Type 2 Diabetes Mellitus
Interventions
Drug: Exendin 9,39
Drug: Placebo
Registration Number
NCT01843855
Lead Sponsor
Adrian Vella
Brief Summary

The study is being undertaken to understand how a gastric bypass can affect a subject's diabetes even prior to their losing significant amounts of weight. The hypothesis of this study is that increased glucagon-like peptide-1 (GLP-1) secretion explains the amelioration in insulin secretion after Roux-en-Y Gastric Bypass (RYGB) surgery.

Primary Outcome Measures
NameTimeMethod
Change in Total Disposition Index from Study 1 (pre-RYGB) to Study 2 (post-RYGB)baseline, 4 weeks post-operative intervention

The total disposition index equals the product of insulin secretion and insulin sensitivity.
