XEOMIN Safety Profile in the Treatment of Cervical Dystonia

Safety demonstrated in a randomized, double-blind, placebo-controlled trial of XEOMIN® (incobotulinumtoxinA)1

Study design

Phase 3, multicenter, double-blind study in 233 patients who were randomized to receive a single treatment of XEOMIN 240 units (n=81), XEOMIN 120 units (n=78), or placebo (n=74). Male and female patients 18 to 75 years of age were eligible if they had cervical dystonia of predominantly rotational form and a TWSTRS Total Score ≥20. Patients previously treated with botulinum toxin were eligible but only if ≥10 weeks had passed since their last injection. Patients had TWSTRS Severity Score ≥10, TWSTRS Disability Score ≥3, and TWSTRS Pain Score ≥1. Patients with swallowing disorders or any significant neuromuscular disease that might interfere with the study were excluded from enrollment.1,2
