About this study

The purpose of this study is to compare the blood glucose control, glycaemic fluctuation and oxidative stress for Type 2 Diabetes between two therapies, one is glargine combined with oral drugs and the other is continuous subcutaneous insulin injection.

Read the detailed description

This study was a single-center, randomized, controled and prospective trial. Type 2 diabetic patients were randomized into 2 groups (Group A and Group B). Subjects in group A would be treated by using continuous subcutaneous insulin injection with insulin lispro, while subjects in group B would be treated by using glargine with oral drugs (metformin and gliclazide modified release tablets). After achieving the target glucose levels by two different approaches in 3-5 days, maintain the target glucose level for 3-5 days. Then a Medtronic dynamic blood glucose meter would be applied to the subjects for 72 hours. The clinical data, such as demographic information, present history, past history, personal history and so on were collected in the 1st day. In the 2nd day and the last day of the trial, the blood samples of the patient were collected for the Laboratory Measurements: Cr, uric acid, aminotransferase, lipid profiles, white blood cell count, N%, fasting plasma glucose, fasting C-peptide, insulin, HbA1c and standard meal test (0.5h-postprandial and 2h-postprandial blood glucose levels, C peptide and insulin, et al. The parameters of b-cell function and glycemia fluctuation were calculated and then analyzed by spss 13.0.

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 3 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: status not confirmed, as of the sponsor's last update on 20 Aug 2015. 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 China. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Zeng Longyi, professor (0086-020-85252160, zssynfmk@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

mean amplitude of glycemic excursions( MAGE) (time frame: 3-5 days after patients achieving the target glucose levels, From date of randomization, assessed up to 10 days). 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 NCT02526810, which also lists 8 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 20 Aug 2015.
