Patient Demographics and Clinical Characteristics• Patients were, on average, 53.6 years of age (range=18.5–93.2 years)• Sex was nearly evenly distributed (female: n=380, 52%; male:
n=350, 48%)• Majority of patients were white (n=562, 77%)• 461 patients (63%) were continuing botulinum toxin treatment for
spasticity• Stroke was the most frequently reported etiology (56%) (Figure 2)
Background• OnabotulinumtoxinA treatment for spasticity
is variable, as treatment is individualized and dependent on numerous factors
Objective• To explore real-world patterns of
onabotulinumtoxinA utilization in patients with lower limb spasticity from the ASPIRE study, over 2 years

ASPIRE provides valuable, real-world data on dosing, injection
guidance, and muscle targeting over 2 years, that may help guide
clinical strategies
This study captured the individualized nature of onabotulinumtoxinA utilization
for spasticity, while demonstrating consistently high satisfaction
These results add to the body of evidence on the
safety and effectiveness of onabotulinumtoxinA
for spasticity

Study Disposition• The ASPIRE study was conducted at 54 sites, by 74 clinicians, across
7 countries and 3 continents (Figure 1)• Primary specialty of clinicians: 59.5% Physiatry, 40.5% Neurology
Average 15.7 years treating spasticity 62% had >10 years of experience using onabotulinumtoxinA to treat
spasticity• 730 patients received ≥1 onabotulinumtoxinA treatment for spasticity
during the 2-year study• 397 patients (54%) completed the 2-year study
OnabotulinumtoxinA Treatment Utilization• The most commonly treated lower limb spasticity presentation was
equinovarus foot (Figure 3) Data on onabotulinumtoxinA dosing, localization method, and muscle
targeting for each lower limb spasticity presentation are shown below

NOTE: Percentages were calculated using naive, non-naive, and total populations as the denominator, in the respective stratifi cations, where more than 1 response was allowed.aIncludes ischemic, hemorrhagic, or embolic stroke.bOther includes hereditary spastic paraparesis, stroke during aneurysm clipping, Chiari malformation, and hydrocephalus.CP = cerebral palsy; MS = multiple sclerosis; SCI = spinal cord injury; TBI = traumatic brain injury.

NOTE: T refers to number of treatment sessions.
Safety• Overall, 197/530 patients (37.2%) reported 643 adverse events (AEs)
21 AEs in 18 patients (3.4%) were considered treatment-related The most common treatment-related AE was muscular weakness
(n=6, 1.1%)• A total of 67/530 patients (12.6%) reported 138 serious AEs• 3 serious AEs in 2 patients (0.4%) were considered treatment-related
Muscular weakness, dysphagia, slow speech• No new safety signals were identifi ed
OnabotulinumtoxinA Treatment Satisfaction• Majority of patients and clinicians were satisfi ed that
onabotulinumtoxinA helped manage spasticity and had sustained benefi t of treatment (Figure 5) The majority of patients and clinicians also indicated that they would
continue onabotulinumtoxinA treatment to manage spasticity
OnabotulinumtoxinA Treatment Information • Treatment strategies often changed between treatment sessions

• ASPIRE is a prospective, observational registry conducted at select sites in North America, Europe, and Asia (NCT01930786)
• Adult patients across multiple etiologies were treated with onabotulinumtoxinA for focal spasticity, including patients non-naive to botulinum toxins
• Treatments were determined by the participating, treating clinician
• Financial support was not provided to the patients for any treatment/treatment-related costs
• Utilization was assessed at each treatment visit, clinician satisfaction at each following visit, patient satisfaction at 5 ± 1 week post-treatment, and follow-up visit approximately 12 weeks after the fi nal visit
