Switching Adult Patients With Spasticity From Onabotulinumtoxina To Abobotulinumtoxina: A Real-World Data Analysis Across Three Us-Based Treatment Centers, Nate Way, Edward Dabrowski, Mitchell Paulin, Martin Taylor, John Madden, Amandeep Mann, Jonathan Bouchard

Conference Presentation Abstracts

Introduction: The therapeutic impact of botulinum toxin type A (BoNT-A) as first-line treatment for adult focal spasticity is well established across numerous therapeutic guidelines. However, relatively little real-world evidence exists to inform clinician decision-making when considering switching patients between BoNT-A products. This 5-year retrospective study aims to illustrate the safe transitioning of patients from onabotulinumtoxinA (ONA) to abobotulinumtoxinA (ABO) therapy in US centers that have considerable experience with BoNT-A usage in adults with spasticity.

Methods: Chart data from patients with upper limb spasticity (ULS), lower limb spasticity (LLS), or upper and lower limb spasticity (ULS+LLS) aged >18 years were collected …

Effect Of Botox And Therapy On Spasticity In Cerebral Palsy: A Critically Appraised Topic, Rachel Bray Mot/S, Tatum Cabot Mot/S, Peyton Clark Mot/S, Cameron Goodman Mot/S, Tarason Moore Mot/S, Claire Napier Mot/S

Master of Occupational Therapy Student Critically Appraised Topics

Children diagnosed with Cerebral Palsy often experience upper limb spasticity. Research has shown Botox injections in combination with occupational therapy can reduce the effects of spasticity in the upper limb. This literature review aims to determine how long is the appropriate duration of occupational therapy to administer after Botox injections to see decreased spasticity in the upper limbs.

Improvements In Lower Limb Spasticity-Related Pain In Children/Adolescents With Cerebral Palsy After Incobotulinumtoxina Injections, Florian Heinen, Michaela Bonfert, Petr Kanovsky, A Sebastian Schroeder, Henry Chambers, Edward Dabrowski, Thorin Geister, Angelika Hanschmann, Michael Althaus, Marta Banach, Deborah Gaebler-Spira

Conference Presentation Abstracts

Introduction: The effects of incobotulinumtoxinA on lower limb (LL) spasticity-related pain (SRP) over multiple treatment cycles (ICs) in children/adolescents (C/As) with cerebral palsy (CP) were analyzed using pooled data from three prospective phase 3 trials.

Patients and methods: C/As aged 2–17 years with CP-associated LL spasticity received incobotulinumtoxinA for 4 ICs. SRP was assessed with the Questionnaire on Pain caused by Spasticity (QPS) using C/A- (direct or via interviewer) and parent/caregiver (P/C)-completed LL modules. The pain population included all C/As with a key QPS item score >0 at baseline; post-baseline scores of 0 indicated complete pain relief.

Results: Data from …

Conference Presentation Abstracts

Introduction: The effects of incobotulinumtoxinA on upper limb (UL) spasticity-related pain (SRP) over multiple treatment cycles (ICs) in children/adolescents (C/As) with cerebral palsy (CP) were analyzed using pooled data from two prospective phase 3 trials.

Patients and methods: C/As aged 2–17 years with CP-associated UL spasticity received incobotulinumtoxinA for 4 ICs. SRP was assessed with the Questionnaire on Pain caused by Spasticity (QPS) using C/A- (direct or via interviewer) and parent/caregiver (P/C)-completed UL modules. The pain population included all C/As with a key QPS item score >0 at baseline; post-baseline scores of 0 indicated complete pain relief.

Prevalence Of Spasticity-Related Pain In Children/Adolescents With Cerebral Palsy, Florian Heinen, Michaela Bonfert, Petr Kanovsky, A Sebastian Schroeder, Henry Chambers, Edward Dabrowski, Thorin Geister, Angelika Hanschmann, Michael Althaus, Marta Banach, Deborah Gaebler-Spira

Conference Presentation Abstracts

Introduction: This analysis determined the prevalence and intensity of spasticity-related pain (SRP) in children/adolescents (C/As) with cerebral palsy (CP).

Patients and methods: Baseline data from the prospective incobotulinumtoxinA trials TIM, TIMO and XARA were pooled. In all three studies, SRP was assessed in C/As aged 2–17 years with lower limb (LL) and/or upper limb (UL) spasticity using the Questionnaire on Pain caused by Spasticity (QPS); both self-reports (direct or via interviewer) and parent/caregiver (P/C) observer reports were included. A C/A was considered to have SRP if any QPS key item score was rated >0 at baseline. Individual QPS modules were …

Absence Of Neutralizing Antibody Formation During Incobotulinumtoxina Treatement Of Spasticity In Botulinum Toxin-Naive Children With Cerebral Palsy: Pooled Analysis Of Three Phase 3 Studies, Henry Chambers, Petr Kanovsky, A Sebastian Schroeder, Edward Dabrowski, Thorin Geister, Angelika Hanschmann, Irena Pulte, Michael Althaus, Marta Banach, Deborah Gaebler-Spira, Florian Heinen

Conference Presentation Abstracts

Introduction: The development of neutralizing antibodies (NAbs) has been linked to secondary non-response to botulinum neurotoxin type A (BoNT-A) injections. This may be of special concern when treating conditions like pediatric spasticity. We investigated NAb formation in three large Phase 3 studies with incobotulinumtoxinA, a BoNT-A lacking complexing proteins, in children/adolescents with cerebral palsy (CP).

Patients and methods: Patients with lower-limb (LL), upper-limb (UL), or combined LL/UL spasticity (2–17 years; uni- or bilateral CP; Ashworth Scale score ≥2 in clinical patterns for treatment) received total body weight incobotulinumtoxinA ≤16–20 U/kg (max. 400–500 U) depending on the study (TIM: NCT01893411; TIMO: …

Safety Of Incobotulinumtoxina In Multipattern Treatment Of Upper And Lower Limb Spasticity In Children/Adolescents With Cerebral Palsy: Pooled Analysis Of 3 Large Phase 3 Studies, Marta Banach, Petr Kanovsky, A Sebastian Schroeder, Henry G. Chambers, Edward Dabrowski, Thorin L. Geister, Hanna Dersch, Michael Althaus, Deborah Gaebler-Spriag, Florian Heinen

Conference Presentation Abstracts

Introduction: This analysis assessed the safety and tolerability of repeated incobotulinumtoxinA treatment for lower-limb (LL), upper-limb (UL), or combined LL/UL spasticity in ambulant and non-ambulant children/adolescents with cerebral palsy (CP) using pooled data from 3 large Phase 3 studies.

Methods: Pediatric patients with spasticity (2–17 years of age; uni- or bilateral CP; Gross Motor Function Classification System [GMFCS] level I-V; Ashworth Scale [AS] score ≥2 in clinical patterns for treatment; clinical need for treatment) were enrolled. Patients received total body incobotulinumtoxinA doses of 16 U/kg body weight (BW, ≤400 U) for LL spasticity in 2 injection cycles (ICs) in TIM …

Chambers, Edward Dabrowski, Thorin L. Geister, Hanna Dersch, Irena Pulte, Michael Althaus, Marta Banach, Deborah Gaebler-Spirag

Conference Presentation Abstracts

Introduction: Spasticity-related pain (SRP) in children and adolescents with cerebral palsy (CP) is common, often neglected, and impacts daily quality of life. We assessed the effect of incobotulinumtoxinA on SRP using pooled data from 3 large Phase 3 pediatric studies.

Methods: Ambulant and non-ambulant patients (2–17 years of age; uni- or bilateral CP; Ashworth Scale score ≥2 in clinical patterns for treatment) were enrolled. Patients received total body incobotulinumtoxinA doses of ≤16 U/kg (≤400 U) for lower-limb (LL) treatment in 2 injection cycles (ICs) in TIM (NCT01893411). In TIMO (NCT01905683), TIM completers and new recruits received 4 ICs with 16–20 …

Chambers, Edward Dabrowski, Thorin L. Geister, Hanna Dersch, Irena Pulte, Michael Althaus, Marta Banach, Deborah Gaebler-Spirag

Conference Presentation Abstracts

Introduction: This pooled analysis assessed the efficacy of incobotulinumtoxinA for lower-limb (LL) and upper-limb (UL) spasticity in children and adolescents with cerebral palsy (CP) using data from the first controlled injection cycle of 2 large Phase 3 studies, TIM (NCT01893411) and XARA (NCT02002884).

Methods: Ambulant and non-ambulant pediatric patients with spasticity due to CP (2–17 years of age; uni- or bilateral CP; Ashworth Scale [AS] score ≥2 in clinical patterns for treatment) were enrolled. Patients were randomized (2:1:1) to 3 incobotulinumtoxinA dose groups: 8, 6, 2 U/kg body weight (BW), maximum 200, 150, 50 U per LL clinical pattern in …
