Trial Outcomes & Findings for Effects of Added D-fagomine on Glycaemic Responses to Sucrose (NCT NCT01811303)

NCT ID: NCT01811303

Last Updated: 2023-09-18

Results Overview

On each intervention, the volunteer measured a baseline fasting blood sugar measurement for that day and repeated this approximately 5 minutes later so that two fasting measurements were obtained under the supervision of staff. All of the subsequent measurements were assessed against the average of the two baseline readings. Each subject was then presented with a test product and they were instructed to consume the whole amount within a fifteen-minute period. Each volunteer then took a blood sugar readings at 15, 30, 45, 60, 90 and 120 minutes following the initiation of consumption of the test product. Measurements were taken using the Ascensia Contour, Blood Glucose Monitoring Systems (Bayer), which analysed the blood sample and provided a blood glucose reading in mmol/l. The AUC is calculated using the trapezoid rule and the final outcome is the incremental area under the curve for the arm expressed as a percent of the average response for the control by the same subject.

Participant Flow

Recruitment of adults volunteers done by RSSL, in Reading (United Kingdom), under GCP.

There was 15 subjects screened that all were complying with the eligibility criteria. Finally only 14 subjects were involved in the study and analysed as far the study was planned to involve 12 subjects. All 14 subjects received the treatment randomized to a William's Latin square design balanced for treatment order.

PRIMARY outcome

Timeframe: 120 minutes

Population: The number of participants \>10, the repetitions \>= 2 and also other variables was determined based on F. Brouns et al., Glycaemic index methodology,Nutrition Research Reviews (2005), 18, 145-171. Also was considered the advice and previous GI studies from RSSL based on master protocol GIMST09.

On each intervention, the volunteer measured a baseline fasting blood sugar measurement for that day and repeated this approximately 5 minutes later so that two fasting measurements were obtained under the supervision of staff. All of the subsequent measurements were assessed against the average of the two baseline readings. Each subject was then presented with a test product and they were instructed to consume the whole amount within a fifteen-minute period. Each volunteer then took a blood sugar readings at 15, 30, 45, 60, 90 and 120 minutes following the initiation of consumption of the test product. Measurements were taken using the Ascensia Contour, Blood Glucose Monitoring Systems (Bayer), which analysed the blood sample and provided a blood glucose reading in mmol/l. The AUC is calculated using the trapezoid rule and the final outcome is the incremental area under the curve for the arm expressed as a percent of the average response for the control by the same subject.

Outcome measures

Outcome measures
Measure
Change D-fagomine/Control AUC at 60 Min
n=14 Participants
Determine the relative change in the Glycaemic response between sucrose with D-fagomine and sucrose without D-fagomine in the first 60 minutes (postprandial). Calculated on incremental Area Under the Curve (AUC) from the individual glucose measurements in capillary blood, and evaluated by repeated measures ANOVA.

n=14 Participants
Determine the relative change in the Glycaemic response between sucrose with D-fagomine and sucrose without D-fagomine in the first 120 minutes (postprandial). Calculated on incremental Area Under the Curve (AUC) from the individual glucose measurements in capillary blood, and evaluated by repeated measures ANOVA.
Postprandial Glycaemic Response Index
73.28 percentage of AUC fagomine/AUC control
Interval 63.66 to 82.9
83.45 percentage of AUC fagomine/AUC control
Interval 67.73 to 99.17

SECONDARY outcome

Timeframe: Usually in the range of 30-45 minutes

Determine the glucose C max of Sucrose with D-fagomine over the baseline. The blood glucose maximum concentration (C-Max) expressed in mmol/L of the average response for a 50g sucrose, over the baseline. Calculation of the outcome is= (Measure glucose C-Max - Measure glucose baseline)
