Summary

Cerebral small vessel disease (cSVD), a result of neurovascular cell dysfunction, is a major cause of stroke, dementia and mobility problems worldwide. Vascular risk factor control alone may not be sufficient to prevent the development of vascular cognitive impairment (VCI) in patients with cSVD according to previous clinical trials.

The presence of glucagon-like peptide-1 receptor (GLP-1R) in cerebral microglia may reveal a potential therapeutic target for prevention of cSVD progression and its disabling clinical outcomes. At the cellular and animal experimentation levels, GLP-1R agonist demonstrated reversal of some pathogenic processes in cSVD. However, its application to cSVD patients remains to be elucidated.

Investigator aims to investigate the safety and efficacy of GLP-1R agonist in patients with moderate-to-severe cSVD.

Description

In this single-center, open-label (assessor blinded), randomized controlled study, 110 patients with cSVD of Age-Related White Matter Changes Scale of 2 or 3 will be randomized into "treatment arm" with GLP-1R agonist and standard medical therapy, and "control" arm with standard medical therapy alone in a 1:1 ratio. In this 78 weeks pilot study, investigators shall evaluate the tolerability and safety profile of exenatide, a GLP-1R agonist in SVD patients, together with changes in clinical, imaging and sonographic parameters.

Clinical and biochemical measures will be assessed at baseline, 12 weeks, 26 weeks and 52 weeks. Transcranial Doppler Ultrasound (TCD) will be performed at baseline, 12 weeks, 26 weeks, 52 weeks and 78 weeks. MRI will be performed at baseline and 78 weeks
