Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The subjects will be divided into intervention arm and control arm with the ratio of 1:1. The intervention is the adjustment of daily insulin dose based on glucose level over 1 week measured using Continuous Glucose Monitoring Device (CGMS)..
CGMS device is a small device placed on the abdomen equipped with a small plastic sensor needle that will be placed under the skin. The device will continuously records the body interstitial fluid glucose level for one week. Study had found that the interstitial fluid glucose level correlates well with the capillary glucose level monitored via finger skin prick. (Thennadil et al, 2001). The device will be placed by a trained nurse and information on the handling and care of the device and its possible complication will be explained in an outpatient appointment. The data will be downloaded using a computer software by a trained research assistant and reviewed retrospectively by a paediatric endocrinologist.
All subjects in both arm will be wearing a CGMS device on their abdomen for 1 week at the beginning of the study. However, the data is made blinded to the subject. In the same time, all subjects will need to continue their usual 4 times per day capillary blood glucose monitoring. Subjects in the intervention arm will have their insulin dose for the next 12 week adjusted according to the data from the CGMS device. This will take into consideration the frequency of hypoglycemia and hyperglycemia episodes.
The device will be worn twice during the whole study period i.e.at the beginning of the study and at week 12. HbA1C level and the number of hypoglycemic episode per week will be measured at baseline, at the end of week 12 and at the end of the study to determine the efficacy and the safety of the CGMS device in improving the glycemic control.
Intervention code [1] 301141 0
Treatment: Devices
Comparator / control treatment
The control arm consist of subjects who has been blindly allocated as control group. These subjects will also wear the CGMS device for 1 week at the beginning and week 12 of the study. However, the data will not be used to adjust the insulin dose but rather as a blinding method. They will continuously check their capillary blood glucose level 4 times per day. The value of this intermittent glucose monitoring will be used to determine the insulin dose for the next 12 weeks.
HbA1C level and the number of hypoglycemic episode per week recorded by the CGMS device will be measured at baseline, at the end of week 12 and at the end of the study to determine the efficacy and the safety of the CGMS device in improving the glycemic control.

Outcomes
Primary outcome [1] 305849 0
Serum HbA1C level
Serum HbA1c is measured using ion exchange high performance liquid chromatography technique at HUSM endocrine lab. The machine is calibrated every 2 weekly. The machine runs in batches every 2 to 3 days where the results will be available from the online lab results application accessible only to clinicians.

Secondary outcome [1] 346761 0
Number of hypoglycemic episodes per week defined as glucose level of 3.6 mmol/L (65 mg/dL)
This represent the safety outcome. Study has shown that the use of CGMS is associated with increase in the duration of hypoglycemia (Yates, Hasnat Milton et al. 2006).
The number of hypoglycemic episodes per week is measured by counting the number of symptomatic and asymptomatic hypoglycemia in a week while wearing the CGMS device as recorded by patient in their record book (in control group) or detected by the CGMS device (in intervention group)

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The allocation procedure will be done by a dedicated research assistant not involved in the data collection and analysis. Interventionist (endocrinologist) and data collector/analyst will not involve in the allocation procedure. The allocation process will be done at a designated room at paediatric clinic coordinated by a dedicated research nurse. Subjects will have to pick up an envelope containing card numbered 1-50. The card will be placed in between 2 black cards in a sealed envelope to ensure no one will be able to identify the number by looking through light source. Patient identification will be written on the envelope and kept away into a file placed in a locked cabinet. All the envelopes will be open by the research nurse away from anyone else. The subject identification and research number will be recorded in a subject database sheet in a file kept by clinic sister in a locked cabinet. Only research nurse and clinic sister have access to the database.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The random allocation sequence will be generated by a research nurse using website https://www.randomizer.org/ Two allocation sequences will be generated by the website. Each sequence will either be the intervention or control group.

Statistical methods / analysis
Data will be entered and analysed using SPSS version 24. The demographic and numerical data were presented by mean (SD) and median (IQR) according to data distribution. The categorical data were expressed as number and percentage.
Repeated measure ANCOVA will be used to measure the mean difference of HbA1c between groups, within groups and between-within groups.
Independent sample t-test will be used analyzed the mean number of hypoglycemic episodes per week between the groups if the outcome variable is normally distributed.
Paired t-test will be used to compare baseline mean number of hypoglycemic episodes per week and the outcome post intervention within each group. If the data follows non-parametric distribution, Wilcoxon Signed-Ranks test of the median difference will be used.
