Clinical Study of GKT in Diabetes Related Dementia

Status Not yet recruiting

Clinical Trial Summary

Recently a new clinical dementia subgroup based on brain imaging, called "diabetes related dementia (DrD)". DrD, unlike Alzheimer's disease and vascular dementia, is considered a "controllable" or "modifiable" form of dementia. However, there is currently a lack of corresponding treatment measures. Ginkgo biloba ketone ester tablets are extracts of Ginkgo biloba leaves. Previous studies have shown that they can increase cerebral blood flow, reduce cerebrovascular resistance, improve cerebral circulation, and are beneficial for the treatment of cognitive impairment. This project intends to explore the role of ginkgo ketoester tablets in diabetes related dementia through a multicenter randomized double-blind controlled clinical study.

Clinical Trial Description

This study was divided into two treatment groups: the experimental group and the control group. 370 type 2 diabetes patients with mild cognitive impairmentpatients were randomly selected and assigned to the experimental group of 185 patients and the control group of 185 patients in a 1:1 equal amount. Experimental group: Ginkgo biloba ketone ester tablets combined with conventional hypoglycemic treatment group, the usage is Ginkgo biloba ketone ester tablets (Styron), taken orally, 3 times a day, 0.5g each time, and continuously administered for 6 months. Control group: conventional hypoglycemic treatment group. The Montreal Cognitive Assessment Basic (MoCA-B) was used for the detection of cognitive dysfunction. Neuropsychological testing of cognitive function was conducted using Alzheimer's Disease Assessment Scale - Cognitive Scale (ADAS-cog), Auditory Word Learning Test (AVLT-H);Assessment of Daily Living Ability - Functional Activity Questionnaire (FAQ);Shape Connection Test A and B and Symbolic Digital Form Test (SDMT).Collect patients' blood, and detect C-reactive protein, interleukin-6, oxidative stress, ApoE4 genotype, phosphorylated tau protein, irisin, β- Amyloid protein before and after the experiment.Detect changes in ankle brachial pulse wave conduction velocity (baPWV)/and ankle brachial blood pressure index (ABI) of patients before and after the experiment. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
