HD Trialfinder Frequently Asked Questions


What is HD Trialfinder?

HD Trialfinder is a clinical trials matching service: a way for individuals with Huntington’s disease, caregivers, healthy volunteers, and physicians to connect with current research studies. It includes an easy-to-use website and free call center staffed by trained HD clinical trial navigators. At www.hdtrialfinder.org, you can read about ongoing studies, and by creating a profile for yourself, a loved one, or a patient, you can find out which nearby studies you are eligible for, and locate contact information to get involved directly.

Where do trial listings come from?

Through involvement in the worldwide HD research community, HDSA keeps track of national, international, and local clinical trials so that the HD Trialfinder listing stays up-to-date with studies that need participants.

  • HDSA outreach to HD researchers nation-wide
  • Exploratory studies funded through the HDSA Human Biology Project
