Valeant and GSK filed a New Drug Application in the U.S. and a Marketing Authorization Application in Europe in 2009. The FDA action date is November 30, 2010.

Approved by the FDA in August 2008, Xenazine® is indicated for the treatment of chorea associated with Huntington's disease (HD).

Pursuant to a supply-and-distribution agreement, Biovail supplies Xenazine® tablets to Ovation for a variable percentage of the product's annual net sales, and pays a royalty to a third party that was acquired by H. Lundbeck A/S in July 2009.
