Effects of onabotulinumtoxinA treatment in patients with and without allodynia: results of the COMPEL study.

ABSTRACT: BACKGROUND:OnabotulinumtoxinA is effective in treating chronic migraine (CM), but there are limited data assessing how allodynia affects preventive treatment responses. This subanalysis of the 108-week, multicenter, open-label COMPEL Study assessed the efficacy and safety of onabotulinumtoxinA in people with CM with and without allodynia. METHODS:Patients (n?=?715) were treated with onabotulinumtoxinA 155?U every 12?weeks for 9 treatment cycles. The Allodynia Symptom Checklist was used to identify patients with allodynia (scores ?3). The primary outcome for this subanalysis was reduction in monthly headache days from baseline for weeks 105 to 108 in groups with and without allodynia. Other outcomes included assessments of moderate to severe headache days, disability (using the Migraine Disability Assessment [MIDAS] questionnaire), and health-related quality of life (Migraine-Specific Quality-of-Life Questionnaire [MSQ] v2). Adverse events and their relation to treatment were recorded. RESULTS:OnabotulinumtoxinA was associated with a significant mean (SD) reduction in headache day frequency at week 108 relative to baseline in patients with (n?=?289) and without (n?=?426) allodynia (-?10.8 [7.1] and?-?12.5 [7.4], respectively; both P?

Project description:BackgroundOnabotulinumtoxinA is effective in preventing chronic migraine (CM); however, the benefit of onabotulinumtoxinA in patients with CM with daily headache is unknown because these patients are typically excluded from clinical trials. This subanalysis of the COMPEL Study assessed the efficacy and safety of onabotulinumtoxinA in people with CM with and without daily headache.MethodsIn total, 715 patients received onabotulinumtoxinA 155 U with or without concomitant oral preventive treatment. Patients who had complete daily diary records for the 28 days of the baseline period were stratified based on daily headache status. The primary outcome variable was reduction in headache-day frequency per 28-day period at 108 weeks (after 9 treatment cycles) relative to baseline. Exploratory outcomes included moderate to severe headache days, migraine disability (using the Migraine Disability Assessment [MIDAS] questionnaire), and health-related quality of life (Migraine-Specific Quality-of-Life Questionnaire v2 [MSQ]). Adverse events and their relatedness were recorded.ResultsOverall, 641 patients had complete daily diary records at baseline. In patients with daily headache (n = 138) versus without (n = 503), treatment with onabotulinumtoxinA was associated with a significant mean (SD) reduction in 28-day headache-day frequency relative to baseline at week 108 (- 10.5 [9.2] vs - 12.2 [6.7], respectively; both P < 0.001) with no significant between-group difference (P = 0.132). The mean (SD) reduction in moderate to severe headache days at week 108 was significant in patients with and without daily headache (- 11.5 [9.4] and - 9.9 [6.4]; P < 0.001) with no significant between-group difference (P = 0.153). Mean (SD) MIDAS scores significantly improved from baseline at week 108 (- 43.3 [73.4] and - 43.6 [46.7]; both P < 0.001), with no significant between-group difference (P = 0.962). Similarly, mean (SD) MSQ subscale scores significantly improved from baseline at week 108 for patients with and without daily headache. OnabotulinumtoxinA was well tolerated in patients with and without daily headache.ConclusionResults indicate that onabotulinumtoxinA is associated with reductions from baseline in headache-day frequency and improvements in disability and quality of life for up to 108 weeks in people with CM with daily headache; however, a longer duration of treatment was required to fully realize the treatment effect on headache. No new safety concerns were identified.

Project description:IntroductionOnabotulinumtoxinA is approved in the USA for the prevention of headache in adults with chronic migraine, a debilitating neurologic disease characterized by headaches occurring on ≥ 15 days per month for > 3 months and including migraine features on ≥ 8 days per month.ObjectiveThe COMPEL Study (NCT01516892), a 108-week, multi-center, open-label study, evaluated the long-term efficacy and safety of onabotulinumtoxinA in adults with chronic migraine. The objective of this subanalysis was to examine the safety and tolerability of onabotulinumtoxinA after each of nine treatment cycles.MethodsOnabotulinumtoxinA 155 U was administered every 12 weeks. Safety and tolerability, overall and by treatment cycle, were assessed. Treatment-emergent adverse events reported between successive treatments were attributed to the preceding treatment. The safety population received one or more doses of onabotulinumtoxinA. The primary efficacy outcome was the reduction in headache days at week 108 compared with baseline.ResultsOf 716 patients enrolled, 373 patients (52.1%) completed the study and 343 (47.9%) withdrew; 481 patients (67.2%) received 60 weeks of treatment and 402 (56.1%) received 108 weeks of treatment. In total, 436 (60.9%) patients reported treatment-emergent adverse events; most were mild/moderate in severity. Thirty-two patients (4.5%) discontinued the study after experiencing treatment-emergent adverse events. The incidence of treatment-emergent adverse events typically decreased with repeated onabotulinumtoxinA treatment: first cycle, 24.2%; fourth cycle, 18.4%; ninth cycle, 12.2%. Neck pain (2.7%), eyelid ptosis (1.8%), musculoskeletal stiffness (1.4%), injection-site pain (1.3%), and headache (1.3%) were the most common treatment-emergent adverse events after the first cycle. Seventy-five patients (10.5%) reported serious treatment-emergent adverse events, 13 (1.8%) withdrew. Treatment-related adverse events were reported by 131 patients (18.3%), one was considered serious. OnabotulinumtoxinA significantly reduced headache day frequency by 10.7 (6.4) days per 28-day period (p < 0.0001) at week 108.ConclusionsOnabotulinumtoxinA treatment was well tolerated over 108 weeks; no new safety signals were identified. The overall incidence of treatment-emergent adverse events and the most common individual events decreased with repeated onabotulinumtoxinA administration.Clinical trial registrationClinicalTrials.gov; NCT01516892.

Project description:BackgroundOnabotulinumtoxinA is approved for the prevention of headache in those with chronic migraine (CM); however, more clinical data on the risk-benefit profile for treatment beyond one year is desirable.MethodsThe Chronic Migraine OnabotulinuMtoxinA Prolonged Efficacy open Label (COMPEL) Study ( ClinicalTrials.gov , NCT01516892) is an international, multicenter, open-label long-term prospective study. Adults with CM received 155 U of onabotulinumtoxinA (31 sites in a fixed-site, fixed-dose paradigm across 7 head/neck muscles) every 12 weeks (±7 days) for 9 treatment cycles (108 weeks). The primary outcome was headache day reductions at 108 weeks; secondary outcomes were headache day reductions at 60 weeks and change in the 6-item Headache Impact Test (HIT-6) score. Safety and tolerability were assessed by reviewing the frequency and nature of adverse events (AEs). AEs were determined at each visit through patient self-report, general non-directed and, for specific AEs, directed questioning, and physical examination. Subgroup analyses for safety and efficacy included, but were not limited to, patients with/without concomitant oral preventive treatment and acute medication overuse at baseline.ResultsEnrolled patients (N = 716) were 18-73 years old and most were female (n = 607, 84.8%). At baseline, patients reported an average 22.0 (SD = 4.8) headache days per month. 52.1% of patients (n = 373) completed the study. By 60 and 108 weeks, a significant reduction in headache days (- 9.2 days and - 10.7 days, respectively, P < 0.0001) was observed. Significant improvements (P < 0.0001) in HIT-6 scores (- 7.1 point change at week 108) were also demonstrated. 131 patients (18.3%) reported ≥1 treatment-emergent adverse events; most frequently reported was neck pain (n = 29, 4.1%). One patient reported a serious treatment-related adverse event (rash). No deaths were reported.ConclusionsThe COMPEL Study provides additional clinical evidence for the consistency of the efficacy and for the long-term safety and tolerability of onabotulinumtoxinA for the prevention of headache in those with CM who have been treated with onabotulinumtoxinA every 12 weeks over 2 years (9 treatments) with the fixed-site, fixed-dose injection paradigm.Trial registrationTrial registration number: NCT01516892 .

Project description:BackgroundIndividuals using onabotulinumtoxinA as a preventive migraine treatment often use acute treatments for breakthrough attacks. Data on real-world effectiveness of the small-molecule calcitonin gene-related peptide (CGRP) receptor antagonist ubrogepant in combination with onabotulinumtoxinA are limited.MethodsCOURAGE, a prospective, multiple attack, observational study, evaluated the real-world effectiveness of ubrogepant (50 or 100 mg) for acute treatment of migraine in people receiving onabotulinumtoxinA, an anti-CGRP monoclonal antibody (mAb), or both. This analysis focused only on onabotulinumtoxinA users. The Migraine Buddy app was used to identify eligible participants and track response to treated attacks. For each ubrogepant-treated attack, meaningful pain relief (MPR) and return to normal function (RNF) at 2 and 4 h post-dose over 30 days was assessed. MPR was defined as a level of relief that is meaningful to the participant, usually occurring before the pain is all gone. After 30 days, satisfaction was reported on a 7-point scale and overall acute treatment optimization was evaluated using the migraine Treatment Optimization Questionnaire-4 (mTOQ-4).ResultsThis analysis included 122 participants who received ubrogepant and onabotulinumtoxinA and reported on 599 ubrogepant-treated attacks. Following the first ubrogepant-treated attack, MPR was achieved in 53.3% of participants 2 h post-dose and in 76.2% of participants 4 h post-dose. RNF was achieved in 25.4% of participants 2 h post-dose and in 45.9% of participants 4 h post-dose. MPR and RNF results were similar across up to 10 ubrogepant-treated attacks. After 30 days, satisfaction with ubrogepant in combination with onabotulinumtoxinA was reported by 69.8% of participants and acute treatment optimization (defined as mTOQ-4 score ≥ 4) was achieved in 77.6%.ConclusionsIn this prospective real-world effectiveness study, ubrogepant treatment in onabotulinumtoxinA users with self-identified migraine was associated with high rates of MPR and RNF at 2 and 4 h as well as satisfaction and acute treatment optimization. Although the lack of a contemporaneous control group limits causal inference, these findings demonstrate the feasibility of using a novel, app-based design to evaluate the real-world effectiveness and satisfaction of treatments.

Project description:IntroductionOnabotulinumtoxinA treatment for spasticity is dependent on numerous factors and varies according to selected treatment goals.ObjectiveTo examine real-world onabotulinumtoxinA treatment utilization and effectiveness in patients with upper limb spasticity over 2 years from the Adult Spasticity International Registry (ASPIRE) study.DesignMulticenter, prospective, observational registry (NCT01930786).SettingFifty-four international clinical sites in North America, Europe, and Asia.PatientsAdults (naïve or non-naïve to botulinum toxins for spasticity) with upper limb focal spasticity related to upper motor neuron syndrome across multiple etiologies.InterventionsOnabotulinumtoxinA administered at clinician's discretion.Main outcome measuresOnabotulinumtoxinA utilization, clinician and patient satisfaction.ResultsFour hundred eighty-four patients received ≥1 treatment of onabotulinumtoxinA for upper limb spasticity. Patients were on average 55.1 years old, 50.8% male, predominantly Caucasian (72.3%), and 38.6% were naïve to botulinum toxins. Stroke was the most frequently reported underlying etiology (74.0%). Most patients (81.2%) had moderate to severe spasticity at baseline. The most commonly treated upper limb clinical presentation was clenched fist (79.1% of patients). Across all presentations, onabotulinumtoxinA doses ranged between 5-600U. Electromyography (EMG) was most often utilized to localize muscles (≥57.0% of treatment sessions). Clinicians (92.9% of treatment sessions) and patients (85.7%) reported being extremely satisfied/satisfied that treatment helped manage spasticity, and clinicians (98.6%) and patients (92.2%) would definitely/probably continue onabotulinumtoxinA treatment. One hundred seventy-nine patients (37.0%) reported 563 adverse events (AEs); 15 AEs in 14 patients (2.9%) were considered treatment related. Sixty-nine patients (14.3%) reported 137 serious AEs; 3 serious AEs in 2 patients (0.4%) were considered treatment related. No new safety signals were identified.ConclusionsASPIRE captured the real-world individualized nature of onabotulinumtoxinA utilization for upper limb spasticity over 2 years, with consistently high clinician- and patient-reported satisfaction. Data in this primary analysis will guide clinical use of onabotulinumtoxinA, as well as provide insights to improve educational programs on spasticity management.

Project description:BackgroundChronic migraine is a neurological condition with a large individual and socioeconomic burden of disease. The recently completed Phase III REsearch Evaluating Migraine Prophylaxis Therapy (PREEMPT) clinical development program established the efficacy and safety of onabotulinumtoxinA as a prophylactic treatment for chronic migraine patients. However, clinical questions remain. A long-term evaluation study of onabotulinumtoxinA aims to address some of the remaining questions in the treatment of chronic migraine. The clinical rationale, study design, and treatment plan of this ongoing study are reviewed in this paper.Methods/designThe Chronic migraine OnabotulinuMtoxinA Prolonged Efficacy open Label (COMPEL) study will enroll approximately 500 adult patients with chronic migraine at international sites. Patients will be evaluated over 108 weeks, following a 4-week baseline period. Qualified subjects will receive 155 U of onabotulinumtoxinA every 12 weeks for 9 open-label cycles. The primary endpoint will be mean change from baseline in frequency of headache days at 108 weeks. Other endpoints will include additional assessments of the efficacy and safety of onabotulinumtoxinA and the effect of onabotulinumtoxinA on quality-of-life measures, disability, and health economic outcomes. The impact of onabotulinumtoxinA on common comorbidities (eg, sleep, anxiety, and fatigue) will also be assessed.DiscussionRecruitment and enrollment are ongoing. Post-approval, open-label studies are often designed to more closely resemble clinical practice and provide an opportunity to continue the evaluation of the efficacy and safety of approved treatments. By creating a large database and analyzing a variety of outcome measures over an extended time frame, the COMPEL study will seek to contribute substantially to the existing knowledge of the chronic migraine population and the long-term management of this debilitating disorder.Clinical trial registration numberNCT01516892.
