Brief Summary

To evaluate efficacy and safety of E2014 (2500U, 5000U, 10000U, placebo) in a multicenter, randomized, double-blind, parallel group comparative study by intramuscularly administering to patients with spasmodic torticollis. Primary endpoint for efficacy evaluation is changes in TWSTRS total scores from baseline measured at Week 4 and the clinical recommended dose will be examined with Williams multiple comparison. For safety evaluation, an inter group comparison (active drug and placebo) will be performed mainly focusing on incidence of adverse events, adverse drug reactions, and abnormal changes in laboratory parameters.

Conditions

Cervical Dystonia; Spasmodic Torticollis

Outcome Measures

Primary Outcomes (1)

• Mean Change From Baseline in the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) -Total Score at Week 4 After Treatment

  The TWSTRS-Total score is the sum of scores of the three components of the scale: * TWSTRS-Severity score which ranges from 0 (=absence of severity) to 35 points (=maximum severity) * TWSTRS-Pain score which ranges from 0 (=no pain) to 20 (=maximum pain) * TWSTRS-Disability score which ranges from 0 (=no disability) to 30 (=maximum disability). The TWSTRS total score ranges from 0 (=best value) to 85 (=worst value). The change from baseline was calculated as the score at the corresponding visit minus the baseline score.

  Baseline, Week 4

Secondary Outcomes (6)

• Mean Change From Baseline in Patient Global Assessment - Visual Analog Scale (PtGA-VAS) at Week 4 After Treatment

  Baseline, Week 4

• Mean Change From Baseline in Physician Global Assessment Disease Assessment - Visual Analog Scale (PGA-VAS) at Week 4 After Treatment

  Baseline, Week 4

• Mean Change From Baseline in the TWSTRS - Functional Disability Score at Week 4 After Treatment

• Patients having only pure retrocollis- or anterocollis-associated symptoms.
• Patients who received botulinum toxin agents within 4 months prior to study treatment of E2014, or those who show carry-over effect of previous treatment with botulinum toxin at the time of starting study administration even though the previous treatment was given 4 months or earlier.
• Patients who were treated with narcotics or antibiotics that may potentiate effects of muscle relaxation (spectinomycin hydrochloride preparations, aminoglycosides, polypeptides, tetracyclines, lincomycins) within 4 months prior to study treatment.
• Patients who started or altered the dose levels of the following agents (musculoskeletal relaxants, antispasm drugs, strong tranquilizers, benzodiazepines including similar drugs, anticholinergic drugs, antiparkinsonian drugs, antidepressants) within 4 weeks prior to study treatment.
• Patients who received medical care(s) other than pharmacotherapies (surgical interventions, MAB, acupuncture, relaxation, etc.) prior to study treatment showing carry-over effect of these cares or unstable condition at the time of starting study treatment.
• Patients who have a history of myectomy or neurectomy in the neck and/or shoulder.
• Patients who have a history of hypersensitivity to E2014's ingredients (botulinum toxin type B, human serum albumin, sodium succinate buffer solution), or other type of botulinum toxins.
• Patients with complication(s) or history of serious neurological or musculoskeletal disease (myasthenia, amyotrophic lateral sclerosis, etc.), cardiovascular disease (acute myocardial infarction, etc.), respiratory disease (COPD, etc.), renal disease (acute or chronic renal failure, etc.), hepatic disease (cirrhosis, etc.), gastrointestinal disease (paralytic ileus, etc.), dermatological disease (toxic epidermal necrosis, etc.), psychiatric disease (schizophrenia, alcohol or drug dependence, etc.), hematological disease (aplastic anemia, etc.), and/or infectious disease (hepatitis, syphilis, AIDS, etc.).
