Accelerating treatments that

make a difference

for Huntington's disease

Founded in 1993, Huntington Study Group (HSG) is an organization of compassionate professionals dedicated to accelerating treatments that make a difference and to improving the quality of life and outcomes for those impacted by Huntington’s disease (HD) through research, education, and collaboration. We build HD-focused teams of clinical researchers, medical professionals, and sponsors, and together partner in the conduct of GCP compliant clinical research, knowledge sharing, and development of innovative treatments for HD.

Advancing HD Clinical Research

HSG has shaped the field of HD research through the development of the Unified Huntington’s Disease Rating Scale (UHDRS), a globally recognized clinical assessment tool, and through expertise spanning more than 30 years and 40 clinical trials and research studies, including pivotal studies supporting FDA-approved treatments for HD chorea. Today, HSG continues to advance discovery through its contributions to ENROLL-HD, the world’s largest observational study of Huntington’s disease, in addition to collaboration on sponsored clinical trials.

HSG Research Services

HSG is the only Partner Research Organization (PRO) fully dedicated to the design and execution of Huntington’s disease trials. In the past 30 years HSG has led more than 40 HD studies – more than any other research organization in the world – including the pivotal trials that led to all three (3) FDA approved treatments for symptoms of HD. HSG is also the only research organization that has a global network of over 130 trial-ready research sites credentialed by HSG to conduct HD research. Many of these sites have successfully and repeatedly contributed to HSG-led trials. The HSG-credentialed site relationships are solid and the cooperation is remarkable through all stages of a trial. HSG reinvests the net revenue generated from clinical trials into our mission-driven initiatives, including site education and training.
