About the Study Drug
The study drug, called valbenazine, is a once-daily oral medication that may be swallowed whole with water. It may also be opened, and the contents (granules) can be sprinkled onto and swallowed with soft food such as applesauce or pudding, or mixed in water and taken via gastrostomy tube. Researchers are comparing the study drug to placebo in the first treatment period, which lasts 14 weeks. The placebo looks just like the study drug but does not contain active ingredients. Placebos allow researchers to fully understand the effects of the study drug. In the second treatment period, which lasts 32 weeks, all participants will receive the study drug.
