The $39.5-million grant to fund stroke study is one of largest ever awarded to investigators at Mayo Clinic in Florida
JACKSONVILLE, Fla. — Is medicine as safe and effective as surgery or stenting in preventing a stroke caused by the buildup of plaque in the carotid artery? Thomas G. Brott, M.D., a neurologist at Mayo Clinic in Florida, aims to find out.
“It’s a critical question. The quality medicines we have today may mean that it is not necessary to perform invasive procedures on patients who do not have warning signs of stroke,” Dr. Brott says. “More than 100,000 carotid surgeries and carotid artery stentings are performed each year in the United States on such patients at risk — and that may not be necessary.”
To find the answer, the National Institute of Neurological Disorders and Stroke (NINDS) has awarded Dr. Brott and his colleague, James Meschia, M.D., $39.5 million — one of the largest grants ever awarded to Mayo Clinic in Florida investigators. The grant funds a seven-year clinical trial that will enroll 2,480 patients in 120 centers in the United States, Canada, Europe and Australia. The study, known as CREST-2, is expected to begin enrolling patients this summer. Management of the patient data and the statistical analysis will be carried out at the University of Alabama at Birmingham under the direction of George Howard, Dr.PH.
