IncobotulinumtoxinA (Xeomin) for Upper Limb Spasticity (NT-Spin)

Prospective, Randomized, Observer-blind, Parallel-group, Multi-center Trial to Assess Efficacy and Safety of Two Different Dilutions of incobotulinumtoxinA (Xeomin) in Patients With Upper Limb Spasticity

This study will investigate the efficacy and safety of incobotulinumtoxinA (Xeomin) in the treatment of arm tightness (upper limb spasticity) using two different dilutions of incobotulinumtoxinA (Xeomin).

Study Overview

• Status: Completed
• Conditions: Upper Limb Spasticity
• Intervention / Treatment: Drug: incobotulinumtoxinA (Xeomin, also known as "NT 201" or "Botulinum toxin type A (150 kD), free from complexing proteins")

Detailed Description

IncobotulinumtoxinA (Xeomin) is a botulinum toxin type A preparation free of complexing proteins. Injected into a muscle, incobotulinumtoxinA causes a reversible local weakening of the muscle for several months, and may improve an impaired muscle function by lessening the muscle tightness within few days. IncobotulinumtoxinA is widely used for various severe neurological conditions. There is some evidence that the treatment effect may be influenced by the amount of the solvent in which incobotulinumtoxinA is diluted before injection.
