Outcome Measures

Primary Outcomes (1)

  • Mean Global Dystonia Rating Scale Score as Measured by Blinded Rater

    This scale measures the severity of dystonia for the jaw and tongue by a blinded rater. Dystonia is rated from 0 to 10: 0=No dystonia present, 1=Minimal dystonia, 5=Moderate dystonia,10=Most severe dystonia

    Baseline, Week 6, Week 12

Secondary Outcomes (12)

  • Change in Analogue Pain Scale Score

    Baseline, Week 12

  • Mean Sialorrhea Clinical Scale for Parkinson's Disease (SCS-PD) Score

    Baseline, Week 6, Week 12

  • Change in Number of Tongue Bites Per Day

    Baseline, Week 12

  • Mean Swallowing Disturbance Questionnaire (SDQ-20) Score

    Baseline, Week 6, Week 12

  • Mean Fahn-Marsden Part B "Speech" Question (BFM-q21) Rating

    Baseline, Week 6, Week 12

  • +7 more secondary outcomes

Study Arms (1)

Dysport Injections

EXPERIMENTAL

Participants with OMD who have been previously treated with any botulinum toxin Type A will be injected with Dysport®.

Drug: Low Dose - AbobotulinumtoxinA

Interventions

Participants will receive low dose AbobotulinumtoxinA injections. Location of injections will be determined by the clinician to treat the individual's dystonic symptom. Muscles that may be included for in injection for OMD with Jaw Closing: Medial Pterygoid 50 units, Masseter 25 units Muscles that may be included in injection for OMD with Jaw Opening: Lateral Pterygoid 50 units, Anterior digastrics 10 units Muscle that will be included in injection for OMD with Tongue Protrusion: Genioglossus 7.5 units

Also known as: Dysport
Dysport Injections

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • a diagnosis of primary or tardive OMD
  • moderate or severe severity, defined as GDS score ≥4 in either "lower face" or "jaw and tongue" section
  • capability of attending the scheduled visits
  • only those who have been previously injected with onabotulinumtoxinA and responded to that treatment, and are at least 12 weeks post last injection
  • Women of childbearing age need to use contraception in order to be included.

You may not qualify if:

  • Existence of a systemic disease that could confound the evaluation
  • previous placement of Deep Brain Stimulation electrodes to treat dystonia
  • concomitant oral medications that could interfere with the action of botulinum toxin Type A (e.g., aminoglycosides)
  • on an unstable dosage of any medication prescribed to treat dystonia (e.g., benzodiazepines, baclofen or anticholinergics)
  • any known hypersensitivity to any botulinum toxin preparation and allergy to cow's milk protein
  • immunoresistance to other forms of botulinum toxin type A
  • existence of a concomitant neuromuscular disorder (e.g., Myasthenia Gravis or Lambert-Eaton syndrome, etc)
  • infection at the proposed injection sites
  • pregnant women
  • women of childbearing age NOT on contraception
  • breastfeeding women
  • inability to comply with scheduled visits
  • patients who had been previously injected with botulinum toxin type A but who did not respond

Limitations and Caveats

The phase 1 study preceding this trial was intended to assess three different Dysport doses. Two participants developed adverse events at the lowest dose in the phase 1 study. Therefore, the lowest dosage level was used for all phase 2 participants.
