For years, Xenazine (tetrabenazine) was the only drug approved by the FDA to treat the chorea associated with Huntington's disease. Now HD families have TWO FDA-approved drugs to treat chorea! Austedo sticks around longer in the body which means it’s potentially easier to dose.It’s very valuable to have options!
The Huntington Study Group did a clinical trial comparing Austedo with Xenazine head-to-head and against placebo as well. Austedo did very well in controlling the chorea. The findings from the Huntington Study Group study led directly to the FDA approving it. As it is FDA-approved, it may be covered by insurance.
