About The Study

Cervical dystonia (CD) is a chronic movement disorder that is painful, debilitating and embarrassing. It is associated with a high prevalence of depression. There is no cure for CD and spontaneous remission is rare.

During the ASPEN clinical study, researchers want to find out if a new investigational product for injection, is safe and effective for use in adults with isolated cervical dystonia (CD) and if the effects last longer than the current standard treatment.

This clinical study will include about 300 adults with moderate to severe isolated cervical dystonia at approximately 80 study centers in North America and Europe.

To qualify for the ASPEN clinical study, you must:

  • be between 18 and 80 years of age
  • have a clinical diagnosis of moderate to severe isolated cervical dystonia
  • not suffer from cervical dystonia due to trauma

Other eligibility criteria must be met.
