A clinical trial led by Keith McCrae, M.D., at Cleveland Clinic demonstrated that pomalidomide, a cancer drug, is safe and effective for treating hereditary hemorrhagic telangiectasia (HHT), a rare bleeding disorder. The trial, supported by the National Institutes of Health, was stopped early due to successful findings and published in the New England Journal of Medicine. Pomalidomide significantly reduced nosebleed severity, required fewer blood transfusions, and improved quality of life for HHT patients.
