What is being measured

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

    Continuous blood glucose monitoring was done in participants using continuous glucose monitoring (CGM) determined over a 6-day period (in order to obtain a continuous 72-hour reading) at baseline and after each active treatment. Glucose coefficient of variation (CV) was calculated based on CGM data dividing the standard deviation of blood glucose values by the mean of the corresponding glucose readings. The participants were analyzed according to treatment received in treatment period 2 as per the sequence reported in this outcome measure.

    Measured: Baseline up to End of Treatment Period 1 (Days 22 to 27)

  2. Change From Baseline in Glycemic Coefficient of Variation (CV) in Treatment Period 2

    Continuous blood glucose monitoring was done in participants using CGM determined over a 6-day period (in order to obtain a continuous 72-hour reading) at baseline and after each active treatment. Glucose coefficient of variation was calculated based on CGM data dividing the standard deviation of blood glucose values by the mean of the corresponding glucose readings. The participants were analyzed according to treatment received in treatment period 2 as per the sequence reported in this outcome measure.

    Measured: Baseline up to End of Treatment Period 2 (Days 66 to 71)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Canagliflozin 300 mg, Sitagliptin 100 mg and Metformin in people with Diabetes Mellitus, Type 2, run by Janssen Research & Development, LLC at 5 sites in Mexico.

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 6 inclusion and 12 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 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Mexico. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Nov 2019). 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?

Change From Baseline in Glycemic Coefficient of Variation (CV) in Treatment Period 1 (time frame: Baseline up to End of Treatment Period 1 (Days 22 to 27)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 Nov 2019.
