NCT00406367

Brief Summary

Patients received one injection with incobotulinumtoxinA (Xeomin) or placebo at baseline. Thereafter, all patients who entered the Open-Label Extension Period (OLEX) received up to five injection sessions of incobotulinumtoxinA (Xeomin) during the OLEX period.

Outcome Measures

Primary Outcomes (1)

  • Jankovic Rating Scale (JRS) Change From Baseline in the JRS Severity Subscore at Week 6 After Injection (Assessed by a Blinded Independent Rater)

    The Jankovic Rating Scale (JRS) is used for classification of the patient's individual symptoms of blepharospasm and for determination of the therapeutic efficacy of study medication. The JRS sumscore is the sum of the two components of the scale: * JRS-Severity score which ranges from 0 (=absence of severity) to 4 (=maximum severity) * JRS-Frequency score which ranges from 0 (=no frequency) to 4 (=maximum frequency) The change from baseline was calculated as the score at the corresponding visit minus the baseline score.

    Baseline, week 6

Secondary Outcomes (3)

  • Jankovic Rating Scale (JRS) Change From Baseline in the JRS Severity Subscore at Week 6 After Injection (Assessed by Subject Diary)

    Baseline, week 6

  • Blepharospasm Disability Index (BSDI) Change From Baseline in the BSDI at Week 6 After Injection

    Baseline, week 6

  • Patient Evaluation of Global Response (PEGR) at Final Visit

    Final visit (up to week 20 after injection of the Main Period)

Study Arms (2)

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female pretreated outpatients between ages 18 and 80 years (inclusive)
  • A clinical diagnosis of bilateral blepharospasm (BEB) characterized by spontaneous, spasmodic, intermittent or persistent involuntary contractions of the orbicular oculi muscles
  • A need for injection of Botulinum toxin (defined by a Jankovic Rating Scale (JRS) severity subscore \>= 2)
  • On a stable dose of other medications (if any) used for focal dystonia treatment (e.g. anticholinergics and benzodiazepines) for at least 3 months prior to and expected throughout the Main Period
  • Source documentation of the last two consecutive injection sessions with BOTOX® and a stable satisfactory therapeutic response directly prior to trial entry
  • At least 10 weeks must have been passed between the last injection with BOTOX® for BEB and Baseline

You may not qualify if:

  • Atypical variant of BEB caused by inhibition of levator palpebrae muscle
  • Myotomy or denervation surgery in the affected muscles (e.g. peripheral denervation and/or spinal cord stimulation)
  • The previous two injections with BOTOX® with more than 50 Units per eye
  • Hypersensitivity to human serum albumin, sucrose, or Botulinum toxin A
  • Neuroleptic induced blepharospasm
  • Diagnosis of myasthenia gravis, Lambert-Eaton syndrome, amyotrophic lateral sclerosis, or any other significant neuromuscular disease which might interfere with the trial
  • Treatment with Botulinum toxins for any indication other than BEB within 4 months prior to Baseline and during the trial
