Brain AVM Study

RDCRNLogo (Official)

Clinical research aims to advance medical knowledge by studying people. The study, entitled “Cerebral Hemorrhage Risk in Hereditary Hemorrhagic Telangiectasia (HHT)” is part of a major effort of the NIH to support research on rare diseases. Cure HHT has joined forces with two other rare diseases to form the Brain Vascular Malformation Consortium (BVMC). The Brain Vascular Malformation Consortium (BVMC; U54NS065705) is a part of the National Institutes of Health (NIH) Rare Disease Clinical Research Network (RDCRN), supported through a collaboration between the NIH Office of Rare Diseases Research (ORDR) at the National Center for Advancing Translational Science (NCATS), and the National Institute of Neurological Disorders and Stroke (NINDS). This is a five year contract award.

HHT Centers of Excellence across North America, along with Cure HHT (also known as the HHT Foundation International, Inc.) are now actively recruiting HHT patients to participate in this NIH funded study. The goal of this research is to determine what genetic and clinical factors signal high risk for hemorrhage from brain AVMs. These risks have never been fully assessed for patients with HHT. Ultimately, the results will help doctors make decisions about brain AVM treatment for individual patients and will drive further research in brain AVM therapies.

Additional enrollment information

HHT patients with a Brain AVM, whether or not its been treated, should contact Nicole Schaefer by email or 410-357-9932 to determine eligibility. NO TRAVEL required, information gathering only, one hour of your time - this is all that is needed to impact this critical area of study!


  • Definite Clinical or Genetic Diagnosis of HHT
  • Brain AVM diagnosis whether treated or untreated
  • Live in the United States, Canada or Europe
  • Be at least 3 years of age

BVMC Study Aims

  1. Correlate brain AVM and brain AVM phenotypes (lesion number, lesion type, initial presentation, etc.) withmRS change (primary outcome) and with intracranial hemorrhage (ICH)
  2. Extend our measurement of AVM bleeding risk in HHT to include the much more common bleeding phenotype in HHT, chronic nasal bleeding, as we hypothesize that there are shared predictors of bleeding across affected organs in HHT.
  3. Identify genetic predictors and circulating biomarkers of severe bleeding (PRO-CB) and brain outcomes in HHT.
