研究概览
简要总结
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.

结局指标
主要结局
Mean Change From Baseline in the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) -Total Score at Week 4 After Treatment
时间窗: Baseline, Week 4
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.
次要结局

- 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(Baseline, Week 4)
- Mean Change From Baseline in the TWSTRS - Pain Score at Week 4 After Treatment(Baseline, Week 4)
- Mean Change From Baseline in the TWSTRS - Severity Score at Week 4 After Treatment(Baseline, Week 4)
- Mean Change From Baseline in Patient Pain Assessment (VAS) at Week 4 After Treatment(Baseline, Week 4)
