HORIZON A Phase III, Randomized, Double-Blind, Placebo-Controlled, Safety and Efficacy Study of Dimebon in Patients with Mild-To-Moderate Huntington Disease

Horizon trial website

Under the direction of Karl Kieburtz, MD, MPH, Principal Investigator (University of Rochester), and Bernhard Landwehrmeyer, MD, co-Principal Investigator (University of Ulm), the Huntington Study Group (HSG), and the European Huntington’s Disease Network (EHDN) are conducting a global collaborative multi-center, randomized, double-blind, placebo-controlled study of Dimebon in individuals with mild-to-moderate Huntington disease (HD). The purpose of the study is to assess the safety and efficacy of Dimebon 60 mg per day, when taken over a period of 6 months. Efficacy is determined by exploring whether or not there is an effect on cognitive (thinking) abilities and overall functioning in people with HD. The study will also evaluate other HD symptoms including behavioral and motor (movement) symptoms. Approximately 50 research centers across North America, Europe, Australia, and New Zealand will enroll approximately 350 individuals. Dimebon is an experimental drug. Research has shown that Dimebon might be effective in preventing the death of brain cells in animals and improving thinking and memory in Alzheimer disease. Results of a HD study in the United States and United Kingdom showed that Dimebon 60mg per day was safe and well tolerated and suggested that Dimebon may improve cognition (thinking abilities) in individuals with HD. This study is being sponsored by Medivation, Inc in collaboration with Pfizer, Inc.
