Pharmacokinetic and Pharmacodynamic Effects of Dorzagliatin in Pancreatic Insufficient-Cystic Fibrosis: A Randomized Double-blind, Cross-over Trial
University of Pennsylvania
Summary
This study is designed to determine the pharmacokinetic and pharmacodynamic response of dorzagliatin 50 mg twice daily following 7-day administration in individuals with pancreatic insufficient cystic fibrosis and abnormal glucose tolerance when compared to randomized, double-blind 7-day administration of placebo in a cross-over fashion. We hypothesize that dorzagliatin administration will result in significant drug concentrations and improved glucose tolerance, early-phase insulin secretion, glucagon suppression, and hepatic glycogen storage assessed during a standardized mixed-meal tolerance test.
