Alternatives for Reducing Chorea in Huntington Disease

Summary

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of SD-809 extended release (ER) in participants switching from tetrabenazine to SD-809 ER. In addition, the safety and tolerability of long-term treatment with SD-809 ER will be assessed in "Switch" participants as well as "Rollover" participants completing a randomized, double blind, placebo-controlled study of SD-809 ER.
