Background: Patient- and caregiver-reported data are lacking on the burden of spasticity, and the impact of botulinum neurotoxin type A (BoNT-A) treatment for this condition, on patients' daily lives. As recommended in recent guidance from the US Food and Drug Administration, online patient communities can represent a platform from which to gather specific information outside of a clinical trial setting on the burden of conditions experienced by patients and caregivers and their views on treatment options in order to inform evidence-based medicine and drug development. Objective: The objective of our study is to characterize spasticity symptoms and their associated burdens on Western European and US patients and caregivers in the realms of work, daily activities, quality of life (QoL), as well as the positive and negative impacts of treatment with BoNT-A (cost, time, QoL) using Carenity, an international online community for people with chronic health conditions. Methods: We performed a noninterventional, multinational survey. Eligible participants were 18 years old or older and had, or had cared for, someone with spasticity who had been treated with BoNT-A for at least 1 year. Patients and caregivers were asked to complete an internet-based survey via Carenity; caregivers reported their own answers and answered on behalf of their patients. Questions included the burden of spasticity on the ability to work, functioning, daily-living activities, and QoL, the impact of BoNT A therapy on patients' lives, and the potential benefits of fewer injections. Results: There were 615 respondents (427 patients and 188 caregivers). The mean age of patients and caregivers was 41.7 years and 38.6 years, respectively, and the most commonly reported cause of spasticity was multiple sclerosis. Caregivers were most often the parents (76/188, 40%) or another family member (51/188, 27%) of their patients. Spasticity had a clear impact on patients' and caregivers' lives, including the ability to work and injection costs. For patients, spasticity caused difficulties with activities of daily living and reduced QoL indices. The median number of BoNT-A injections was 4 times per year, and 92% (393/427) of patients reported that treatment improved their overall satisfaction with life. Regarding the BoNT-A injection burden, the greatest patient-reported challenges were the cost and availability of timely appointments. Overall, 86% (368/427) of patients believed that a reduced injection frequency would be beneficial. Caregivers answering for their patients gave largely similar responses to those reported by patients. Conclusions: Spasticity has a negative impact on both patients' and caregivers' lives. All respondents reported that BoNT A treatment improved their lives, despite the associated challenges. Patients believed that reducing the frequency of BoNT-A injections could alleviate practical issues associated with treatment, implying that a longer-acting BoNT-A injection would be well received.

Chronic migraine (CM) is associated with impaired health-related quality of life and substantial socioeconomic burden, but many people with CM are underdiagnosed and do not receive appropriate preventive treatment. OnabotulinumtoxinA and topiramate have demonstrated efficacy (treatment benefit under ideal conditions) for the prevention of headaches in people with CM in clinical trials, but real-world studies suggest markedly different clinical effectiveness (treatment benefit based on a blend of efficacy and tolerability). This study sought to evaluate patient-reported outcomes (PROs) of onabotulinumtoxinA versus topiramate immediate release for people with CM. FORWARD was a prospective, multicenter, randomized, parallel-group, open-label, phase 4 study comparing onabotulinumtoxinA 155 U every 12 weeks with topiramate 50 to 100 mg/day for ≤36 weeks in people with CM. PROs measured included the Headache Impact Test (HIT-6), 9-item Patient Health Questionnaire Quick Depression Assessment (PHQ-9), Work Productivity and Activity Impairment Questionnaire: Specific Health Problem (WPAI:SHP), and Functional Impact of Migraine Questionnaire (FIMQ). A total of 282 patients were randomized and treated with onabotulinumtoxinA (n = 140) or topiramate (n = 142). From baseline to week 30, mean HIT-6 test scores improved significantly in patients taking onabotulinumtoxinA compared with topiramate (P < .001). Improvements in depression over time were observed via larger changes in PHQ-9 scores with onabotulinumtoxinA than topiramate (P < .001). Work productivity assessed via WPAI:SHP scores revealed significant improvements with onabotulinumtoxinA versus topiramate in Work Productivity Loss (P = .024) and Activity Impairment (P < .001) domains. Results from the FIMQ also revealed a larger reduction from baseline with onabotulinumtoxinA vs topiramate (P < .0001). OnabotulinumtoxinA treatment had more favorable real-world effectiveness than topiramate on depression, headache impact, functioning and daily living, activity, and work productivity. The overall study results suggest that the beneficial effects on a range of PROs are the result of improved effectiveness when onabotulinumtoxinA is used as preventive treatment for CM.

Background and Purpose Poststroke spasticity often negatively affects functional activities and daily living and frequently is accompanied by pain, abnormal limb postures, and contractures. The purpose of this case report is to describe the long-term benefit of botulinum toxin A in a patient with poststroke spasticity. Case Description A 35-year-old woman with poststroke upper-limb spasticity who had lost function in her left hand was treated with onabotulinumtoxinA and physical therapy. Over 25 months, the patient received a physical therapy and occupational therapy program and received onabotulinumtoxinA injections into muscles of the left hand and arm, significantly reducing tone and facilitating recovery of function. Practical assessments, the Ashworth Scale, and electrophysiology were used to measure changes over time. No functional scales or dexterity scales were used to measure changes. Outcomes OnabotulinumtoxinA injections were discontinued when treatment goals were attained, and no further improvements were achieved. After more than 2½ years without further onabotulinumtoxinA treatments, the patient maintained range of motion and some functional use and dexterity in her left hand. Discussion This case report illustrates the efficacy and long-term benefit of onabotulinumtoxinA, combined with physical therapy and occupational therapy, in the successful treatment of poststroke spasticity.

The aim of this study in patients with post-stroke lower limb spasticity (PSLLS) was to evaluate the relationship between time of onabotulinumtoxinA treatment relative to stroke and efficacy outcomes. This was a phase 3, international, multicenter, randomized, 12-week, double-blind study, followed by a repeated treatment, open-label extension. Patients were aged 18–85 years with PSLLS (Modified Ashworth Scale [MAS] ≥ 3) of the ankle with the most recent stroke occurring ≥ 3 months before screening. Patients (double-blind phase) were randomized (n = 468) to onabotulinumtoxinA 300–400 U (300 U, mandatory ankle muscles (gastrocnemius, soleus, tibialis posterior); and ≤ 100 U, optional lower limb muscles (flexor digitorum longus, flexor hallucis longus, flexor digitorum brevis, extensor hallucis, and rectus femoris]) or placebo. Primary endpoint: MAS change from baseline (average score of weeks 4 and 6). Secondary endpoints: physician-assessed Clinical Global Impression of Change (CGI) average score of weeks 4 and 6 and physician-assessed Goal Attainment Scale (GAS; active and passive, weeks 8 and 12). When stratified by time since stroke (≤ 24 months, n = 153; > 24 months, n = 315, post hoc), patients treated ≤ 24 months post-stroke experienced greater improvements from baseline versus placebo in MAS (− 0.31 vs − 0.17), CGI (0.49 vs 0.12), and passive GAS scores (week 12, 0.37 vs 0.26). A ≥ − 1-point improvement in active (week 12; p = 0.04) and passive (week 8; p = 0.02) GAS scores versus placebo was achieved by more patients treated ≤ 24 months post-stroke; in patients treated > 24 months post-stroke, improvements were only observed in active scores (week 8; p = 0.04). OnabotulinumtoxinA 300–400 U was well tolerated, with no new safety findings.

Cervical dystonia (CD) is primarily treated with botulinum toxin, at intervals of ≥ 12 weeks. We present efficacy, patient-reported outcomes (PROs), and safety in adults with CD at the last available visit after a single set of abobotulinumtoxinA (aboBoNT-A) injections versus placebo using 500 U in a 2-mL injection volume. In this 12-week, randomized, double-blind trial, patients were ≥ 18 years of age with primary idiopathic CD, had a Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) total score ≥ 20, and TWSTRS-Severity subscale score > 10 at baseline. Patients (N = 134) were randomized (2:1) to aboBoNT-A (n = 89) or placebo (n = 45), with aboBoNT-A patients treated with 500 units (U) if toxin-naïve, and 250 to 500 U based on previous onabotulinumtoxinA dose if non-naïve. Endpoints included total TWSTRS, Pain Numeric Rating Scale (NRS-Pain; 24-hour), Treatment Satisfaction Questionnaire for Medication, and other PROs for pain, depression, and global health. Results are for the intent-to-treat population, with “Week 12” (Wk12) comprising the last available post-baseline assessment (end-of-study or early withdrawal). Mean TWSTRS total scores improved from 42.5 at baseline to 35.4 at Wk12 with aboBoNT-A and 42.4 to 40.4 with placebo (treatment difference: –4.8; 95% confidence interval [CI]: –8.5, –1.1; p = 0.011). At Wk12, mean (95% CI) change from baseline in NRS-Pain was –1.0 (–1.59, –0.45) for aboBoNT-A and –0.2 (–0.96, 0.65) for placebo. AboBoNT-A demonstrated numeric improvements in other PROs. More aboBoNT-A–treated patients than patients receiving placebo reported being at least “somewhat satisfied” with treatment (60.4% vs 42.2%, respectively), symptom relief (57.0% vs 40.0%), and time for treatment to work (55.8% vs 33.3%). No new adverse events were reported. Results indicate that in patients with CD, treatment with aboBoNT-A using a 2-mL injection provided sustained improvement in the TWSTRS total score and patient-perceived benefits up to 12 weeks.
