Our Accomplishments

The Huntington Study Group (HSG) has conducted more than 30 clinical trials and studies since its founding in 1993. HSG developed the Unified Huntington’s Disease Rating Scale (UHDRS®), an invaluable research tool that provides a uniform assessment of the clinical features and course of HD. More recently, HSG conducted trials that led to the first, and to-date, only, FDA-approved drug (tetrabenazine) for the treatment of HD.

Our collaborators and sponsors number in the dozens and include major pharmaceutical companies, foundations, CROs and academic institutions. HSG is highly regarded as a facilitator of Huntington Disease (HD) clinical trials and studies because of its high standards for its research sites (more than 120), investigators and coordinators (more than 400) and its large, international network of researchers dedicated to finding treatments that make a difference for HD.
