Registered outcomes2
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Second-phase insulin response during GPA test | 5 hours | The key endpoint of interest will be the change in second phase insulin response derived from the Glucose-Potentiated Arginine (GPA) test. The GPA test will measure insulin (and other glucose controlling hormones) which will be a measure of pancreatic endocrine function in response to injection of arginine. Arginine is a naturally occurring amino acid (substance) in the body. It will be given in the veins to make the pancreas secrete insulin. After the first injection of arginine, a glucose infusion will be started in order to raise the level of sugar in the blood to 230 mg/dl. Once the level is achieved, arginine will be injected again and blood samples are measured. After a 2 hour break, the glucose infusion will be started to achieve a blood sugar of 340mg/dl and arginine injection will be repeated. Comparison of responses with incretin vs. placebo will be performed using statistical methods, specifically, paired t-test or Wilcoxon matched pair test. |
| Secondary | Change in insulin secretion among CF groups | 5 hours | The change in second phase insulin secretion induced by incretins will be compared among the different subgroups of patients with CF (Ind-GT, IGT, and early CFRD) groups using nonparametric comparison of changes in slope, estimated using Mann-Whitney methods. |
