About this study

Official title: Clinical Trial Protocol for Contour Link System With Contour Sensor

Subjects with diabetes and study staff used an investigational blood glucose monitoring system.

Conditions: Diabetes
Being tested: Contour Link Investigational Blood Glucose Monitoring System
Medical subject headings: Diabetes Mellitus

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Contour Link Investigational Blood Glucose Monitoring SystemDevice
Subjects with diabetes and study staff each performed Blood Glucose tests from the subject's capillary blood obtained from fingerstick using the Contour Link investigational meter.

What is being measured

The primary outcome is the main question the study is designed to answer.

Percent of Fingerstick Blood Glucose (BG) Results Within +/-20%(>=75 mg/dL) and Within +/- 15mg/dL (<75 mg/dL) of Laboratory Glucose Method
Subjects with diabetes and study staff tested subject fingerstick blood using an investigational blood glucose meter (BGM). BGM results were compared to a reference lab glucose method - Yellow Springs Instrument (YSI) Analyzer. BG results were used to calculate the number of BG results within +/- 20% (for reference BG results >=75mg/dL) and within +/- 15mg/dL(for reference BG results <75mg/dL) of the reference method results.
Measured: 1 hour

Secondary outcomes (1)

Number of Subjects Rated as<=3 Performing Basic Meter Tasks (Labeling Evaluation)
Subjects read User Guide(UG)to learn to use the system and performed meter tasks. Study staff observed, then rated subjects' success (1 to 4) at performing tasks. Scale: 1.Performed tasks correctly without assistance. 2.Performed tasks correctly, but was directed to a specific part of the UG by the study staff as in a Customer Service call. 3.Performed tasks correctly, but required additional review/assistance similar to review of a specific function during a Customer Service call. 4.Subject incorrectly performed part of the testing regimen and was unaware of the error.
Measured: 1 hour

Population analysed: As a result of one subject's low blood sugar (and thus rapidly changing glucose values) during the study, one subject did not complete the study. The remaining 77 subjects tested 2 test strip lots on the system. 2x77(154) test results were available.

1 secondary outcome is reported in the full results.

What does the primary outcome measure?

Percent of Fingerstick Blood Glucose (BG) Results Within +/-20%(>=75 mg/dL) and Within +/- 15mg/dL (<75 mg/dL) of Laboratory Glucose Method (time frame: 1 hour). 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 NCT01328717.

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.
