Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
The study duration will be 5 days. On day one, the participant will be connected to a continuous blood glucose monitor sensor (CGMS), which will remain in place for the 5 day duration of the study. The CGM sensor is a small plastic catheter inserted just beneath the skin. For 5 consecutive days the participant will be instructed to eat a standard evening meal with consistent amounts and type of carbohydrate. Usual insulin doses will be given prior to the meal for the carbohydrate content. This will be followed by a test meal (a protein drink) to be consumed 4 hours later. The participant will then fast overnight. The blood glucose level (BGL) will be observed via the CGM every hour for an 8 hour period (overnight). The participant will then test their BGL each morning of the study prior to breakfast with a fingerprick blood test, as per usual diabetes management for individuals with type 1 diabetes mellitus.

Not applicable
Comparator / control treatment
The participants postprandial blood glucose level will be compared 8 hours following a meal containing protein with the postparandial BGL following a non protein meal.
The first day of the study period the participant will not cosume a protein meal. Each day for the following 4 days they will be given a test meal containing various amounts of protein.
Control group
Uncontrolled

Outcomes
Primary outcome [1] 288930 0
The primary outcome will be measured using the data from the CGM trace.
The primary outcome will be the glucose excursion at 8 hours after the test meal of protein.
Timepoint [1] 288930 0
8 hours after the test meal is consumed
Secondary outcome [1] 301377 0
The rate of maximal BGL increase every hour up to 8 hours post prandial.
Timepoint [1] 301377 0
