Upper Limb Spasticity

Brief summary

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).

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.

Interventions

DRUGincobotulinumtoxinA (Xeomin, also known as NT 201 or Botulinum toxin type A (150 kD), free from complexing proteins)

active ingredient: Clostridium Botulinum neurotoxin Type A free from complexing proteins; powder for solution for injection; Mode of administration: intramuscular injection; The content of the vial was dissolved in 2.0 or 5.0 mL of sterile sodium chloride \[NaCl\] 0.9% solution without preservatives. Dilution with 2.0 or 5.0 mL resulted in a dose of 50 or 20 units per 1.0 mL.

Design outcomes

Primary

MeasureTime frameDescription
Responder in Disability Assessment Scale (DAS) at Week 4 - Per Protocol SetAt week 4The primary efficacy endpoint is the number of responder at Week 4; response defined as an improvement (reduction) of at least one point in the DAS for the primary therapeutic target from baseline visit to Week 4. The DAS determines the functional impairment for the domains hygiene, dressing, limb position and pain according to the following scale: 0 = no disability; 1 = mild disability; 2 = moderate disability; 3 = severe disability. At Screening visit, the subject and investigator, selected together one of the four domains as the primary therapeutic target.

Participant flow

Recruitment details

216 female and male subjects with upper limb spasticity caused by either stroke, brain injury, spinal cord injury, multiple sclerosis or cerebral palsy were screened starting February 2007. Recruitment advertisements according to local law and approved by the responsible IEC were published as needed.

Pre-assignment details

The protocol contained a screening period of 7 days to allow evaluation of laboratory and ECGs in order to determine eligibility. 24 subjects were screening failures due to violation of selection or protocol criteria.

Responder in Disability Assessment Scale (DAS) at Week 4 - Per Protocol Set

The primary efficacy endpoint is the number of responder at Week 4; response defined as an improvement (reduction) of at least one point in the DAS for the primary therapeutic target from baseline visit to Week 4. The DAS determines the functional impairment for the domains hygiene, dressing, limb position and pain according to the following scale: 0 = no disability; 1 = mild disability; 2 = moderate disability; 3 = severe disability. At Screening visit, the subject and investigator, selected together one of the four domains as the primary therapeutic target.

Time frame: At week 4

Population: Analysis is based on Per Protocol Set, defined as all randomized subjects who received at least one dose of study drug and who have no major deviation from study protocol. For this set of subjects no missing values can occur for the primary endpoint.

Change From Baseline in Passive Range of Motion (PROM) - Elbow Extension

For the PROM all motions of wrist and elbow were measured from a defined neutral starting point position. The degrees of motion were added in the direction the wrist and elbow moved from the neutral starting position. The neutral starting position was the position of an upright standing/sitting person. The angle of the motion from the neutral starting position was measured in degrees using a goniometer. Angles were measured for the wrist with maximal dorsal extension, neutral position and maximal palmar flexion, and for the elbow with maximal extension, neutral position and maximal flexion.

Time frame: baseline, week 4, week 12, follow up (between week 12 and week 20)

Population: Analysis is based on Full Analysis Set, defined as all randomized subjects who received at least one dose of study drug. Missing values were not imputed.

Change From Baseline in Passive Range of Motion (PROM) - Wrist Maximum Flexion

For the PROM all motions of wrist and elbow were measured from a defined neutral starting point position. The degrees of motion were added in the direction the wrist and elbow moved from the neutral starting position. The neutral starting position was the position of an upright standing/sitting person. The angle of the motion from the neutral starting position was measured in degrees using a goniometer. Angles were measured for the wrist with maximal dorsal extension, neutral position and maximal palmar flexion, and for the elbow with maximal extension, neutral position and maximal flexion.
