FDA Approves Teva’s Huntington’s Disease Drug
FDA has approved a Teva Pharmaceutical Industries NDA for Austedo (deutetrabenazine) tablets for treating chorea (uncontrollable muscular tremors) associated with Huntington’s disease. Approval was based on data from a Phase 3 multi-center trial conducted in 90 ambulatory patients with manifest chorea associated with Huntington’s. “Total Maximal Chorea Scores for patients receiving Austedo improved by approximately 4.4 units from baseline to the maintenance period (average of Week 9 and Week 12), compared to approximately 1.9 units in the placebo group,” the company says. The drug was approved with a warning that the drug can increase the risk of depression and suicidal thoughts and behavior (suicidality) in Huntington’s patients.
