An Extension Study to Evaluate the Long-Term Safety and Efficacy of Votoplam in Participants With Huntington's Disease (HD)
This study is looking into the long-term safety and effects of a medicine called Votoplam for people with Huntington's disease. Participants who were already in a previous study with Votoplam will continue to take it to see how it works over a longer time.

A Safety and Pharmacokinetics Trial of VO659 in SCA1, SCA3 and HD
This study is testing a new drug called VO659 for people with certain genetic conditions affecting movement: Spinocerebellar Ataxia Type 1, Spinocerebellar Ataxia Type 3, and Huntington's Disease. It's looking at how safe the drug is and how the body handles it. This is a very early stage trial.

Pridopidine Phase 3 Study in Huntington's Disease
This study looks at whether a drug called pridopidine can slow down Huntington's disease (HD) in adults. It also checks if the drug is safe. Participants will take pridopidine or a dummy pill for a year, with regular check-ups, to see if it helps with HD symptoms.

GENERATION HD2. A Study to Evaluate the Safety, Biomarkers, and Efficacy of Tominersen Compared With Placebo in Participants With Prodromal and Early Manifest Huntington's Disease
This study, GENERATION HD2, is looking at a new drug called tominersen for Huntington's disease. Researchers want to see how safe it is, how it affects the body, and if it helps people in the early stages of the condition. It's comparing tominersen to a dummy drug.
United States · Argentina · Australia - ongoing, recruitingTherapeutic confirmatory (Phase III)
Randomised, double-blind, placebo-controlled study to evaluate the effect of metformin, an AMPK activator, on cognitive measures of progression in Huntington's disease patients.
This study is looking at whether a common diabetes medicine called metformin could help people with Huntington's disease with their thinking and memory. It compares metformin to a dummy pill to see if it makes a difference to how the disease progresses.

IMarkHD: in Vivo Longitudinal Imaging of HD Pathology
This study uses special brain scans (PET and MRI) to understand how Huntington's disease (HD) changes the brain over time. Researchers are looking at what causes symptoms and how the disease progresses, hoping to find better ways to diagnose and treat HD.
