Cerebral Arteriovenous Malformation Clinical Trial
Official title:
Lovastatin for Treatment of Brain Arteriovenous Malformations:a Double-blind, Placebo-controlled Randomized Trial
The purpose of this pilot study is to evaluate the disease-modifying efficacy of lovastatin in patients with brain arteriovenous malformation.
Brain arteriovenous malformations are lesions that consist of multiple arteries and veins,
connecting as a fistula without intervening normal capillary bed. As the disease progresses,
the lesion may cause several adverse clinical events including stroke, seizure or even death.
For patients with BAVM deemed unsuitable for invasive treatment or who has elected to defer
invasive treatment, it is essential to take effective medical management.
Lovastatin possesses antiinflammatory and antiproliferative actions in human endothelial and
vascular smooth muscle cells independent of its lipid-lowing action. These findings suggest
that lovastatin may be beneficial for maintaining vascular stability, which may contribute to
slowing down the progression of the disease and reducing the incidence of adverse clinical
events.
The purpose of this pilot study is to evaluate the safety and disease-modifying efficacy of
lovastatin in patients with BAVMs. Participants will be randomly assigned to receive either
combination of lovastatin and symptomatic treatment drugs or combination of placebo and
symptomatic treatment drugs. Patients will have post-dose safety follow-up visit at 1, 3, 6,
and 12 months after the study begins. The changes in clinical outcomes, including lesion
volume changes and the rate of stroke, seizure or death, will be evaluated in a period of 2
years.
