About this study

Official title: A Pilot Dose Ranging Study of Dysport® (AbobotulinumtoxinA) in the Treatment of Oromandibular Dystonia

The purpose of this study is to study the efficacy and safety of AbobotulinumtoxinA (Dysport) for use in Oromandibular Dystonia (OMD).

Read the detailed description

Oromandibular dystonia (OMD) is an uncommon, disabling form of cranial dystonia, involving involuntary movements of the lower facial, masticatory, and lingual muscles. This can cause jaw movements including opening, closure, protrusion, retraction, or deviation. Common additional facial movements involve grimacing or lip pursing. When there is tongue involvement, it usually presents as tongue protrusion or curling. Such patients are impaired in relation to eating, speaking and swallowing

This study aims to evaluate the efficacy and safety of a low dose of Dysport® deemed tolerable during phase 1 in subjects with oromandibular dystonia (OMD).

Participants will be injected with Dysport® only, with an unblinded open-label disclosure. The safety and efficacy pf receiving Dysport® will be recorded for all subjects that undergo injection. All subjects will be examined and videotaped at the injection visit, then at 6 and 12 weeks after injection with a standardized protocol. The primary outcome will be blinded examination scores of the videos performed after the study is complete.The evaluators will be three different movement disorders experts, not otherwise involved in the study, who will review the videotaped examinations, presented in a random order, using the Global Dystonia Rating scale (GDS). Evaluators will rate the dystonia at baseline (injection visit) and 6 weeks after injection.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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

    Measured: Baseline, Week 6, Week 12

Secondary outcomes (12)
  1. Change in Analogue Pain Scale Score

    Measure of jaw pain by visual analogue scale (0-100) where 0 represents "no pain" and 100 represents the "most severe pain".

    Measured: Baseline, Week 12

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

    The SCS-PD measures drooling. Individual items are scored on a scale from 0-3 where 0 represents "never" and 3 represents "always". The overall maximum score is 21. A higher score indicates greater drooling severity. A lower score indicates lesser severity.

    Measured: Baseline, Week 6, Week 12

  3. Change in Number of Tongue Bites Per Day

    The patient will be asked to estimate how many times they tend to accidentally/involuntarily bite their tongue per day.

    Measured: Baseline, Week 12

  4. Mean Swallowing Disturbance Questionnaire (SDQ-20) Score

    Ease of chewing and swallowing will be assessed by the SDQ-20 (modified to exclude question 5 due to redundancy as it relates to drooling and question 15 which is not relevant to the study as it involves prior aspiration pneumonias). Individual items are scored from 0 (never) to 3 (very frequently). The overall score is the total for all items; a higher score indicating more frequent swallowing disturbance; a lower score indicating no or less frequent disturbance, with a possible maximum score of 39.

    Measured: Baseline, Week 6, Week 12

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

    The Fahn-Marsden Part B "Speech" Question assesses the ease of producing speech. Responses range from 0=Normal, 1=Slightly involved, easily understood, 2=Some difficulty understanding, 3=Marked difficulty understanding.

    Measured: Baseline, Week 6, Week 12

  6. Mean Oromandibular Dystonia Quality of Life Questionnaire (OMDQ-25) Score

    The OMDQ-25 is a subjective quality of life measurement made for patients with Oromandibular Dystonia. The maximum total score is 100 indicating the highest quality of life. A score of 50 indicates a mediocre quality of life. A lower score indicates perceived lower quality of life.

    Measured: Baseline, Week 6, Week 12

  7. Mean Global Clinical Impression - Improvement Scale (CGI) Index Score

    The Clinical Global Impression - Improvement scale (CGI-I) is a 7 point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to a baseline state at the beginning of the intervention. Responses are scored on a scale from 1 to 7; 1 represents "very much improved" and 7 represents "very much worse".

    Measured: Week 6, Week 12

  8. Mean Global Clinical Impression Scale (CGI-S) With Severity Index Score

    The Clinical Global Impression - Severity scale (CGI-S) is a 7-point scale that requires the clinician to rate the severity of the patient's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. Responses are scored on a scale from 1 to 7; 1 represents "normal, not at all ill" and 7 represents "among the most extremely ill patients".

    Measured: Baseline, Week 6, Week 12

  9. Mean Global Clinical Impression- Efficacy Index Score

    The Clinical Global Impression - Efficacy Index is a 4×4 rating scale that assesses the therapeutic effect of treatment. Responses range on a scale from 0 to 4 with 4 being the best response.

    Measured: Week 6, Week 12

  10. Mean Unified Dystonia Rating Scale (UDRS) Score as Measured by Un-blinded Rater

    The UDRS measures dystonia severity. The UDRS is being rated by un-blinded video evaluators regarding severity of subject's dystonia. Scores range from 0 to 10; 0 indicating no dystonia, 5 indicating moderate dystonia, and 10 indicating the worst dystonia.

    Measured: Baseline, Week 6, Week 12

  11. Mean Global Dystonia Rating Scale Score as Measured by Un-blinded Rater

    This scale measures the severity of dystonia for the jaw and tongue by an un-blinded rater. Dystonia is rated from 0 to 10:

    0=No dystonia present, 1=Minimal dystonia, 5=Moderate dystonia,10=Most severe dystonia

    Measured: Baseline, Week 6, Week 12

  12. Mean Unified Dystonia Rating Scale (UDRS) Score as Measured by Blinded Rater

    The UDRS measures dystonia severity. The UDRS is being rated by blinded video evaluators regarding severity of subject's dystonia. Scores range from 0 to 10; 0 indicating no dystonia, 5 indicating moderate dystonia, and 10 indicating the worst dystonia.

    Measured: Baseline, Week 6, Week 12
