The Pride-HD Study

NOTE: This study has concluded and is no longer enrolling.

What is the Pride-HD Study?

Pride-HD is a Phase II clinical research study of an investigational drug called pridopidine in people who have a diagnosis of Huntington disease (HD). The purpose of this randomized, double blind study is to see what effect the investigational drug, pridopidine, has on movement, thinking, and behavior, compared to placebo, in people with Huntington disease after 26 weeks of receiving either pridopidine or placebo. In addition, information will be collected about safety and tolerability of pridopidine in people with HD.

What is pridopidine?

Pridopidine, the investigational drug being studied may have an effect on some of the symptoms of Huntington’s Disease that depend on dopamine. Dopamine is a substance that is naturally made by the human body. It is made in many areas of the brain, and affects how people behave, think and move. It has been suggested that changes in the way dopamine works in Huntington’s Disease creates signs and symptoms of the condition. This study is being conducted to determine if pridopidine helps with the signs and symptoms of Huntington’s Disease.
