16 Comparative Treatments

i Description/ name of comparative treatments

This will be a randomized, double-blind, placebo-controlled study. One hundred and forty dementia/stroke-free subjects having confluent WMH as defined by the global score of the Age-Related White Matter Changes scale of ≥2 will be randomized into active (cilostazol 100mg bd) (n=70) and placebo (n=70) treatment respectively, for 2 years. Primary outcome will be change of WMH volume on MRI, which will be quantified automatically. Secondary outcomes include change in other brain measures (lacunes, microbleeds, cortical grey matter and whole brain volumes, diffusion tensor imaging measures, arterial spin labeling) and clinical measures (Montreal Cognitive Assessment, executive and memory tests, behavior, instrumental activities of daily living, gait, incident clinical events [e.g. stroke, dementia]). Data on clinical and biochemistry measures will be collected at baseline, 1 year and 2 year; while MRI will be performed at baseline and 2 year. Safety will be assessed using adverse events and laboratory tests.
