Summary

This Phase 2 trial tests whether adding valbenazine (a daily pill) to standard botox injections can further reduce neck muscle spasms and pain in people with cervical dystonia. About 20 adults who still have symptoms despite botox will receive either valbenazine or a placebo for 12 weeks. The study measures changes in a severity scale for neck dystonia.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: valbenazine
What this could lead to: If it works, this could point toward a new oral add-on treatment to improve motor symptoms in people with cervical dystonia who still have symptoms after botox injections.
What could go wrong: This is a small, early Phase 2 trial with only 20 participants, so results may not apply to everyone. The drug may not provide meaningful benefit or could cause side effects.
