Percentage change in the incremental area under the glucose response curve (AUC) after 75g glucose for capsules and tablets containing Axulin powder relative to the water control. Incremental AUC is the AUC below the curve above the fasting level; area below fasting is ignored. Percentage change will be calculated as 100 x (A-P)/P where A and P are the mean AUC's after Axulin and water control treatments, respectively. The blinded AUC results for the 6 treatments will be subjected to repeated measures analysis of variance (ANOVA) examining for the main effects of treatment and participant-group, and treatment*group interaction. After demonstration of significant heterogeneity among the 6 coded treatments, differences between individual means will be assessed using Tukey's test to adjust for multiple comparisons. The code will be broken after this analysis has been done. The percentage changes will be considered to be significant if the difference in mean AUC is significant.

Percentage Change in Area Under The Curve (AUC) for Serum Insulin 0-2 Hours

Insulinogenic Index is an index of the ability of a change in blood glucose to stimulate an increase in serum insulin. It is a unitless measure with higher numbers indicating improved beta cell function. It is calculated by dividing the change in serum insulin between 0 and 30 minutes by the change in blood glucose between 0 and 30 minutes.

Insulinogenic Index

Matsuda Insulin Sensitivity Index is an index of whole body insulin sensitivity derived from glucose and insulin responses after a 75g Oral Glucose Tolerance Test (OGTT). It is calculated by 10000 divided by the square root of (FG*FI*MG*MI) where FG is fasting glucose, FI is fasting insulin, MG is the mean AUC for blood glucose at 0, 30, 60, 90 and 120 minutes and MI is the mean AUC for serum insulin at 0, 30, 60, 90 and 120 minutes.

Matsuda Insulin Sensitivity Index

Insulin Secretion-Sensitivity Index-2 (ISSI-2) is an index of β-cell function with insulin secretion adjusted for whole body insulin sensitivity. It is calculated by the total area under the curve for serum insulin divided by the area under the curve for blood glucose, and that result times the Matsuda insulin sensitivity index (defined above).
