This is a prospective, randomized, open label, parallel, 76-week study to explore and evaluate the therapeutic effects of Liraglutide, Empagliflozin and Linagliptin on the cognitive function, olfactory function, and odor-induced brain activation in T2DM patients with mild cognitive impairment (MCI).
Full description
This is a prospective, randomized, open label, parallel, 76-week study to explore and evaluate the therapeutic effects of Liraglutide, Empagliflozin and Linagliptin on the cognitive function, olfactory function, and odor-induced brain activation in T2DM patients with MCI inadequately controlled with metformin monotherapy. The investigators will screen in the outpatient and inpatient departments to enroll 324 patients (108 for each arm) totally with the inclusion and exclusion criteria in 76 weeks. The patients will be randomized at a 1:1:1 ratio into Liraglutide, Empagliflozin and Linagliptin 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 8-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.
