Efficacy Comparison of Polyethylene Glycol Loxenatide and Gliclazide on the Brain Function in T2DM Patients

Type 2 Diabetes Mellitus Clinical Trial

Official title:
Efficacy Comparison of Polyethylene Glycol Loxenatide and Gliclazide on the Brain Function in T2DM Patients: a Randomized, Parallel Controlled Clinical Trial

Clinical Trial Summary

This is a prospective, randomized, open label, parallel,4-month study to explore and evaluate the therapeutic effects of polyethylene glycol loxenatide on the cognitive function, olfactory function, and odor-induced brain activation in T2DM patients with normal cognitive status or MCI.

Clinical Trial Description

This is a prospective, randomized, open label, parallel, 4-month study to explore and evaluate the therapeutic effects of polyethylene glycol loxenatide on the cognitive function, olfactory function, and odor-induced brain activation in T2DM patients with normal cognitive status or MCI inadequately controlled with metformin monotherapy. The control group was treated with Gliclazide. There are 1 principal investigator, 6 sub-investigators and 1 nurse in research centre. The sub-investigators will screen in the outpatient and inpatient departments to enroll 58 patients (29 patients for each arm) totally with the inclusion and exclusion criteria in 9 months. The patients will be randomized at a 1:1 ratio into loxenatide and Gliclazide treatment group with a computer-generated random order. All patients will also continue on their existing dose and regimen of metformin throughout the study. At the baseline, clinical information collection, 100g-steamed bread meal test, biochemical measurement, body composition analysis, cognitive assessment, olfactory test and functional magnetic resonance imaging(fMRI) scan will be conducted for all patients. During the treatment period, visits at 4-week intervals will be performed to evaluate the safety of drugs and adjust the dose of metformin if hypoglycaemia occurs; meanwhile, fasting and 2-hour postprandial plasma glucose assayed by fingerstick, physical examination, and olfactory test will be conducted. At the end of the study, all of the assessments will be performed again for all recruited subjects, including early withdrawal patients. ;
