About this study

Official title: Performance of the G3 Blood Glucose Monitoring System With TATSU Strip

The purpose of this study is to demonstrate that untrained subjects who have diabetes can operate the Investigational Blood Glucose Monitoring System (BGMS) and obtain valid glucose results.

Conditions: Diabetes
Being tested: G3 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.

G3 Investigational Blood Glucose Monitoring SystemDevice
Untrained subjects with diabetes perform self Blood Glucose (BG) tests with capillary fingerstick blood and AST of the palm using the G3 meter and an investigational sensor. Study staff test subject venous blood and all BG results are compared to a reference laboratory glucose method. Untrained subjects utilize some additional features of the meter using the User Guide and provide feedback.

What is being measured

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

Percent of Self-Test Fingerstick Blood Glucose Results Within +/- 5to15mg/dL (<100mg/dL) or Within +/- 5to15% (>=100mg/dL) of Laboratory Glucose Method
Untrained subjects with diabetes self-test fingerstick blood using an investigational Blood Glucose Monitoring System (BGMS). BGMS results are compared with capillary plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI Analyzer BG results are used to calculate the number of BGMS results within +/- 5to15mg/dL (<100mg/dL YSI capillary plasma) or +/- 5to15% (>=100mg/dL YSI capillary plasma). Site staff tested in parallel after subjects.
Measured: 1 hour

Secondary outcomes (3)

Percent of Glucose Results From Alternative Site Testing (AST) of the Palm Within +/- 15mg/dL (<75mg/dL) or Within +/- 20% (>=75mg/dL) of Laboratory Glucose Method
Untrained subjects with diabetes self-test Alternative Site (AST) Palm blood using an investigational Blood Glucose Monitoring System (BGMS). BGMS AST results are compared with capillary plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI capillary plasma BG results are used to calculate the number of AST BGMS results within +/- 15mg/dL (<75mg/dL YSI capillary plasma) or +/- 20% (>=75mg/dL YSI capillary plasma).
Measured: 1 hour
Percent of Venous Blood Glucose Results Within +/- 5to15mg/dL (<75mg/dL) or Within +/- 5to20% (>=75mg/dL) of Laboratory Glucose Method
Study staff tested subject venous blood using an investigational Blood Glucose Monitoring System (BGMS). Venous BGMS results are compared with venous plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI venous plasma results are used to calculate the number of BGMS results within +/- 5to15mg/dL (<75mg/dL YSI venous plasma) or +/- 5to20% (>=75mg/dL YSI venous plasma).
Measured: 1 hour
Number of Subjects Able to Perform Given Tasks Using Product Labeling for Instruction
After reading the instructions for use, and without assistance from the study staff, subjects use the BGMS to utilize some of the additional features of the system. Study staff documents Yes or No 'Did the subject complete the task successfully?'
Measured: 1 hour

Questions about this trial

What is this clinical trial studying?

A study testing G3 Investigational Blood Glucose Monitoring System in people with Diabetes, run by Ascensia Diabetes Care at 2 sites in United States.

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 4 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 29 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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?

Yes. Results are posted in the registry (first posted 3 Jan 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percent of Self-Test Fingerstick Blood Glucose Results Within +/- 5to15mg/dL (<100mg/dL) or Within +/- 5to15% (>=100mg/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 NCT01474317.

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 29 Feb 2016.
