Treatment of Tourette syndrome
Habit reversal training (HRT), massed negative practice, biofeedback, relaxation, hypnosis and other behavioral approaches are proposed as alternative treatments of tics, but few have been well assessed. Relaxation techniques, such as exercise, yoga or meditation, may be useful in relieving stress that may aggravate tics, but the majority of behavioral interventions (such as relaxation training and biofeedback, with the exception of habit reversal) have not been systematically evaluated and are not proven therapies for Tourette's.
Neurocrine Biosciences
Neurocrine announced it filed a new drug application (NDA) for its once-daily valbenazine drug treating TD on August 29, 2016. Valbenazine received a priority review designation, fast track status and a breakthrough designation from the FDA. In April 2017, the FDA approved INGREZZA (valbenazine) for the treatment of TD. At the time of approval, it was the first and only drug approved for adults with TD. Neurocrine is also studying valbenazine in clinical trials for the treatment of Tourette Syndrome. In October 2017, Neurocrine announced that it had been granted orphan drug designation status from the FDA for valbenazine for the treatment of pediatric patients with Tourette syndrome.
