Study summary

This is a randomized, double-blind, placebo-controlled, parallel group, multi-center trial of two doses of daxibotulinumtoxinA (DAXI) for injection (high-dose; low-dose in adult subjects with isolated (primary) cervical dystonia (CD).

Read the detailed description

Approximately 300 subjects, recruited from approximately 80 study centers in the United States (US), Canada, and Europe will be randomized to DAXI for injection high dose, DAXI for injection low dose, or placebo group, respectively. Subjects will be stratified by treatment center and history of prior treatment with botulinum neurotoxin (BoNT).

Inclusion criteria

  • Adults, 18 to 80 years of age
  • Meets diagnostic criteria for isolated CD (idiopathic; dystonic symptoms localized to the head, neck, shoulder areas) with at least moderate severity at Baseline (Day 1), defined as a TWSTRS-total score of at least 20, with at least 15 on the TWSTRS-Severity subscale, at least 3 on the TWSTRS-Disability subscale, and at least 1 on the TWSTRS-Pain subscale

Exclusion criteria

Exclusion Criteria:

  • Cervical dystonia attributable to an underlying etiology, (e.g., traumatic torticollis or tardive torticollis)
  • Predominant retrocollis or anterocollis CD
  • Significant dystonia in other body areas, or is currently being treated with BoNT for dystonia in areas other than those associated with isolated CD
  • Severe dysphagia (Grade 3 or 4 on the Dysphagia Severity Scale) at Screening or Baseline (prior to study treatment)
  • Any neuromuscular neurological conditions that may place the subject at increased risk of morbidity with exposure to BoNT, including peripheral motor neuropathic diseases (e.g., amyotrophic lateral sclerosis and motor neuropathy, and neuromuscular junctional disorders such as Lambert-Eaton syndrome and myasthenia gravis)
  • Previous treatment with any BoNT product for any condition within the 14 weeks prior to Screening
  • Botulinum Neurotoxin Type A (BoNTA), except the investigational daxibotulinumtoxinA, treatment-experienced subjects who had suboptimal or no treatment response to the most recent BoNTA injection for CD, as determined by the investigator, or history of primary or secondary non-response to BoNTA injections, known to have neutralizing antibodies to BoNTA; or have a history of botulinum toxin type B (rimabotulinumtoxinB [Myobloc/Neurobloc]) injection for CD due to non-response or suboptimal response to BoNTA

Interventions

  • BiologicalDaxibotulinumtoxinA for injection

    DaxibotulinumtoxinA for injection is a sterile, white to off-white lyophilized product containing the active ingredient, daxibotulinumtoxinA, and inactive ingredients to be reconstituted with sterile, non-preserved, 0.9% sodium chloride solution saline.

  • BiologicalPlacebo

    Placebo is a sterile lyophilized product consisting of inactive ingredients without the neurotoxin to be reconstituted with sterile, non-preserved 0.9% sodium chloride solution.

What researchers measure

Primary outcomes

  1. Change from Baseline Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS)-total score

    TWSTRS is used to assess the severity of cervical Dystonia and the success of its treatment. The average of the change from baseline in TWSTRS-total score at Weeks 4 and 6 will be determined. TWSTRS-total score has a minimum score of 0 and a maximum score of 85, where higher scores represent worse outcomes. It is made up of the summation of 3 subscales: the Torticollis Severity Scale (minimum score of 0, maximum score of 35), the Disability Scale (minimum score of 0, maximum score of 30), and the Pain Scale (minimum score of 0, maximum score of 20).

    Time frame: Week 4 and Week 6

Secondary outcomes

  1. Change from Baseline TWSTRS-total score

    Change from baseline in TWSTRS-total score (all post-treatment time points)

    Time frame: Up to 36 Weeks

  2. Duration of effect

    Duration of effect based on target TWSTRS score

    Time frame: Up to 36 Weeks

  3. Patient Global Impression of Change (PGIC) Improvement

    Percentage responders at Week 4 or 6

    Time frame: Week 4 or Week 6

  4. Incidence of treatment-emergent adverse events (Safety)

    Evaluation of adverse events and serious adverse events over the course of the study.

    Time frame: Up to 36 Weeks

Other outcomes

  1. Change in TWSTRS subscale scores

    Change from baseline in TWSTRS subscale scores (TWSTRS-Severity, TWSTRS-Disability, and TWSTRS-Pain) (all post-treatment time points)

    Time frame: Up to 36 Weeks

  2. Clinical Global Impression of Change (CGIC)

    CGIC at all post-treatment time points

    Time frame: Up to 36 Weeks

  3. Patient Global Impression of Change (PGIC)

    PGIC at all post-treatment time points

    Time frame: Up to 36 Weeks
