About this study
Official title: Protocol: Comparing the Effect of Using an Internet-Based Glucose Monitoring System Versus the Continuous Glucose Monitoring System on HbA1c Levels in Type 2 DM
Management of type 2 diabetes is an ongoing challenge for patients and their doctors. In order to prevent short and long term complications, patients need to monitor and control their blood sugar levels. In addition, they may need to have an ongoing communication with their doctor in order to modify treatment. In this study the investigators wish to compare two systems of monitoring and communication of blood sugar levels. The first is the use of continuous glucose monitoring system and the second is the use of an Internet-based glucose monitoring system. The investigators want to compare their effect and/or benefits.
Read the detailed description
Purpose: To compare the benefits of the Internet-based glucose monitoring system with the Continuous Glucose monitoring system in patients with type 2 diabetes mellitus.
Hypothesis:The investigators propose that the benefits from the Internet-based glucose monitoring system (IBGMS) will be comparable to the benefits of the Continuous Glucose monitoring system (CGMS) for patients with type 2 DM.
Justification: Half of the subject will be on the standard treatment, which will involve glucose monitoring by testing blood glucose 3 times daily, performing a laboratory test of blood hemoglobin every three months, and visiting the doctor every three months for standard care. They will also use the internet system to report their glucose readings,which will allow the health care professions to view the results and provide feedback. The other half will use the continuous glucose monitoring system, which will involve a minimum of testing blood glucose at least 2 times a day to calibrate the sensor, performing laboratory test of blood hemoglobin every three months, and visiting the doctor every three months for standard care. All of the subjects will be under standard care;
Research Method: Type 2 diabetes patients who satisfy the inclusion criteria will be recruited from St. Paul's Diabetes Teaching and Training Centre. They will be randomized into 2 groups (IBGMS and CGMS). There is an equal chance, a 50/50 chance, of being placed in either group.
The IBGMS group will receive standard care and will be asked to perform self-blood glucose monitoring 3 times daily for 6 months. The IBGMS group will also be asked to report their blood glucose reading every 2 weeks through an Internet based glucose monitoring system. The IBGMS group will make visits to the endocrinologist every 3 months with A1c and serum creatinine measurements at 3-month intervals for 6 months.
The CGMS group will also receive standard care and will be asked to perform self-blood glucose monitoring at least 2 times a day for 6 months to calibrate the sensor.The CGMS group will also be using the internet system to generate a report of their blood glucose readings and can be used at the patient's own preference. Their readings will also be sent to the endocrinologist for feedback every 2 weeks. The CGMS group will make visits to the endocrinologist every 3 months with A1c and serum creatinine measurements at 3-month intervals for 6 months. The laboratory measurements of both groups will be recorded and used for data analysis.
Statistical Analysis: The primary endpoint is the A1c level or the change in A1c level. The secondary endpoints include severe hypoglycemia defined as requiring external aid, hospital admissions for any CVD related intervention, and adverse events such as unplanned hospitalizations for any cause that last more than 24 hours. Patients who do not have the required number of SMBG (Self monitored blood glucose) tests performed or patients requiring new laser therapy will be asked to discontinue the study.
For each group, A1C levels before the start of study will be compared to A1C levels 3 and 6 months after the start of the study. Paired t-tests and random effects models (longitudinal analyses) will examine differences in A1C values before and after the study duration. Unpaired, independent t-tests will be done to examine the difference in A1C values between the two groups before and after the interventions. The planned sample size is 50.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Remote Blood Glucose MonitoringOther
Also called Internet Blood Glucose Monitoring System
The subjects enrolled in the Internet Therapeutic Intervention arm receive standard care by testing their blood glucose at least 3 times daily and visit the endocrinologist every 3 months; however, they are also asked to upload their blood glucose readings online every 2 weeks for the health practitioner to view and comment upon.
Continuous Glucose MonitoringOther
Also called Sensors, CGMS
The use of CGMS (Sensor, receiver, transmitter) (Medtronic Diabetes) plus the uploading of results to the Internet-based software utility of CareLink Personal and generating reports that can be viewed and used at the patient's own preference. This group will not receive feedback or suggestion based on the uploaded glucose data.

Questions about this trial
What is this clinical trial studying?
A study testing Remote Blood Glucose Monitoring and Continuous Glucose Monitoring in people with Type 2 Diabetes Mellitus, run by Endocrine Research Society at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: paused, as of the sponsor's last update on 11 Sep 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The primary endpoint is the A1c level or the change in A1c level (time frame: 6 Months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01162694, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Sep 2014.
