Arm 2

Arm Type

Active Comparator

Placebo Comparator

Arm Label

Doxycycline

Placebo

Arm Description

Patients undergoing elective vascular malformation surgery will receive doxycycline100 mg twice a day, a dose shown to effectively decrease MMP or placebo, treatment for two weeks prior to surgery

Patients undergoing elective vascular malformation surgery will receive doxycycline100 mg twice a day, a dose shown to effectively decrease MMP or placebo, treatment for two weeks prior to surgery

Outcomes

Primary Outcome Measures

Our primary aim is to perform a pilot study to document the effect of doxycycline therapy to decrease MMP expression in the vascular malformation tissue.

Secondary Outcome Measures

Our secondary aims are: (1) To explore whether plasma MMP-9 levels can be used as a marker for MMP-9 inhibition in the vascular malformation lesional tissue

5. Study Description

Brief Summary
Brain vascular malformations, including arteriovenous malformations (AVM), cavernous malformations (CVM) and aneurysms, are a source of life-threatening risk of intracranial hemorrhage. The etiology and pathogenesis are unknown. There is no medical therapy presently available. Prevention of spontaneous intracerebral hemorrhage (ICH) is the primary reason to treat brain vascular malformations. The goal of this study is to: begin pilot studies to lay the groundwork for future clinical trials to develop medical therapy to decrease ICH risk. Matrix metalloproteinases (MMPs) regulate the extracellular matrix in association with various hemorrhagic brain disorders. MMP-9 has been most consistently associated with vascular wall instability and hemorrhagic brain disorders. Doxycycline, a non-specific MMP inhibitor, may enhance vascular stability, thus reducing the risk of spontaneous hemorrhage in brain vascular malformations by decreasing MMP-9 activity.
Detailed Description
Doses will be randomized by the Pharmacy Department at UCSF for Doxycycline 100 mg/BID and Placebo BID. These will be prepared in blister-packs. Depending on enrollment/surgery date, patients will take medication either one to two weeks before surgery. Patients will be assigned to a treatment group according to a random table. Each patient will be initially provided with a 1 or 2-week supply of drug in blister packs. The patient will take the final dose of study drug on the morning of surgery. Baseline labs will be obtained and then again at time of surgery along with a piece of surgical tissue.
