Adding valbenazine to botox for neck muscle spasms
Treatments studied
Part of Bones, joints & muscles, Brain & nervous system clinical trials.
This study tests if adding a daily pill (valbenazine) to regular botox injections can better reduce neck muscle spasms. It helps people whose botox works but may not be enough.

This trial tests a new botulinum toxin medication (IPN10200) for adults with cervical dystonia, a condition that causes painful muscle spasms in the neck and shoulders. It aims to see if the treatment is safe and effective in reducing symptoms.
This study tests whether combining physiotherapy with Botox injections can improve neck control in people with cervical dystonia. It also looks at how 'sensory tricks' (like touching your face) help the brain control symptoms, using brain scans to understand why.
This trial tests if taking zinc supplements can improve symptoms of cervical dystonia (a condition causing neck muscle spasms) for people who already get Botox injections. It adds zinc to your regular Botox treatment to see if it helps control symptoms better.
This study compares two different brain stimulation targets to treat cervical dystonia (painful neck muscle contractions). It may help people whose symptoms are no longer controlled by neck medicine or botulinum toxin shots.
This study tests a type of brain stimulation called TMS to see if it can improve neck muscle spasms in people with cervical dystonia. It's for adults who haven't had Botox recently and are not on other treatments.
This study tests botulinum toxin (a medication that relaxes muscles) to treat various involuntary movements like tremors, muscle spasms, or uncontrolled facial movements. The goal is to see if this treatment can reduce your symptoms and improve your quality of life.
