Trial summary
Management of type 2 diabetes is an ongoing challenge for patients and their doctors. In order to prevent complications, patients need to monitor and control their blood sugar levels.

About this study
Management of type 2 diabetes is an ongoing challenge for patients and their doctors. In order to prevent 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 the benefits of continuous glucose monitoring system (CGMS) to an internet-based glucose monitoring system (IBGMS). The investigators also want to determine whether the frequency of blood glucose testing affects blood glucose control and to see whether the benefits of CGMS and IBGMS are independent of testing frequency.
Read the detailed description
In this current study, the investigators wish to test several hypotheses: whether the frequency of SMBG is correlated with HbA1c, whether the knowledge that strips are being counted affects HbA1c, whether the reduction of HbA1c when using an IBGMS is independent of the frequency of testing, and whether there is a difference between IBGMS and CGMS in HbA1c reduction.
The investigators will recruit 100 patients with type 2 diabetes who satisfy the inclusion/exclusion criteria. For the first visit, the patients will be immediately randomized into four groups. One group will be testing 3 times a day (SMBG). The second group will be similar to the SMBG group except they will know that we are counting the frequency of testing (SMBG With Knowledge). The third group will use an IBGMS and the fourth group will use a CGMS. During the first visit, we will teach the patient how to use the programs and machinery for their group. All four groups will be asked to follow the protocol and to visit their doctor in 3 month intervals for 6 months along with completed laboratory blood test results.
For the SMBG and the SMBG With Knowledge group, each will be given a new meter and be asked to test 3 times a day. They will also be required to keep a diary of their SMBG levels. The difference between the two is that the SMBG With Knowledge group will know that we are counting strips. The SMBG group will believe that we are testing a new meter and will not know that the SMBG With Knowledge group exists. This deception is necessary to test the experimental effect of if the patient knows that we are counting the frequency of testing, does that affect the frequency that they are testing. The investigators will tell the SMBG group that we are testing the accuracy of a new meter and they should test 3 times a day.
For the CGMS and IBGMS group, they will also be counting the frequency of blood glucose testing to see whether the benefits from both are independent of the number of tests. Furthermore, we wish to compare the these two methods of blood glucose monitoring. Both groups will have to upload their data onto the internet and communicate with their doctor every 2 weeks using a secure online web site.
At the end of 3 and 6 months, we will collect the frequency of testing from each group to determine whether increased glycemic control correlates with increased testing. We will also collect their SMBG diaries to see whether the written data correlates with the data on their meter. The investigators will also be comparing a measure of their blood glucose levels for each group and determining the effectiveness of CGMS and IBGMS.

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.
SMBGOther
The SMBG patients will be told that we are testing a new meter to check the accuracy of the meter. They will be asked to test at least 3 times a day and to keep a written diary of their sugar levels. The SMBG group will not know that we are counting strips and can not know about the SMBG With Knowledge group as it may bias the frequency that they test.
SMBG With KnowledgeOther
The SMBG With Knowledge patients will be given a new meter and will be asked to test at least 3 times a day and to keep a written diary of their sugar levels. We will inform this group that we are measuring the frequency of SMBG testing.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Management of type 2 diabetes is an ongoing challenge for patients and their doctors. In order to prevent 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.

The investigators will recruit 100 patients with type 2 diabetes who satisfy the inclusion/exclusion criteria. For the first visit, the patients will be immediately randomized into four groups.

Questions about this trial
What is this clinical trial studying?
A study testing Remote Blood Glucose Monitoring, Continuous Glucose Monitoring and SMBG 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 9 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: finished, 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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 NCT01175408, which also lists 7 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.
