What is being measured

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

  1. Change in Insulin Sensitivity Measures: Insulin Sensitivity Index (ISI)

    Insulin sensitivity as measured by a combination of insulin sensitivity index (ISI) which should go up after 3 month treatment period to show improvement, and insulin sensitivity (SI) which should go down after 3 month treatment period to show improvement. Note that the ISI as developed by Matsuda and DeFronzo from a calculation based on results from a standard oral glucose tolerance test (OGTT) (doi: 10.2337/diacare.22.9.1462 Diabetes Care September 1999 vol. 22 no. 9 1462-1470) is recorded as units on an arbitrary scale. SI data is based on a calculation derived from analysis of results of frequently sampled intravenous glucose tolerance test (FSIVGTT) by Bergman et al (doi:10.1172/JCI112886/J Clin Invest. 1987;79(3):790-800) and is reported with units min-1/(µlU/L).

    Measured: baseline and 3 months

  2. Change in Insulin Sensitivity Measures: Insulin Sensitivity (SI)

    Insulin sensitivity as measured by a combination of insulin sensitivity index (ISI) which should go up after 3 month treatment period to show improvement, and insulin sensitivity (SI) which should go down after 3 month treatment period to show improvement. Note that the ISI as developed by Matsuda and DeFronzo from a calculation based on results from a standard oral glucose tolerance test (OGTT) (doi: 10.2337/diacare.22.9.1462 Diabetes Care September 1999 vol. 22 no. 9 1462-1470) is recorded as units on an arbitrary scale.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

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

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 in Insulin Sensitivity Measures: Insulin Sensitivity Index (ISI) (time frame: baseline and 3 months). 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?

On the ClinicalTrials.gov record for NCT00682890, which also lists 1 linked publication.

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.
