Trial Outcomes & Findings for Acute Effect of HP-211 (Axulin) on Blood Glucose and Serum Insulin Responses in Healthy Lean and Overweight Humans (NCT NCT03135015)

NCT ID: NCT03135015

Last Updated: 2020-04-20

Results Overview

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.

Participant Flow

Participants were recruited from 26-APRIL-2017 to 24-MAY-2017 at GI Labs (20 Victoria St., Toronto ON, M5C 2N8).

A screening visit was conducted to ensure each participant met inclusion/exclusion criteria for the study. Participants that qualified for the study were separated into either the lean or the overweight group as per protocol (11 subjects/arm).Participants were assigned to a randomization schedule in order of enrollment within each group.

PRIMARY outcome

Timeframe: 0, 15, 30, 45, 60, 90, and 120 minutes post-dose

Population: The analysis of primary outcome data is based on all randomized subjects who received this intervention and for whom primary outcome data is known. There is no missing value imputation.

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.

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.

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.

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).

POST_HOC outcome

Timeframe: From Baseline at 90 minutes

Population: The analysis of the outcome measure is based on all randomized participants who received this intervention and for whom the outcome data is known. The comparison is between the water control and the placebo capsules only. There is no missing value imputation.

Change from baseline (CFB) in blood glucose will be computed at 90 minutes. The CFB results for the water control and the placebo capsule treatments will be subjected to a paired t-test examining whether the mean difference between the two sets of observations is equal to zero.

POST_HOC outcome

Timeframe: 1-2 hours post-dose

Population: The analysis of other outcome measures is based on all randomized subjects who received this intervention and for whom the outcome data is known. There is no missing value imputation.

Incremental area under the blood glucose response curve (AUC) will be computed using the values recorded at 60 minutes and beyond. The blinded AUC results for the Axulin capsule treatments and the water control 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 3 coded treatments, differences between individual means will be assessed using Tukey's test to adjust for multiple comparisons.
