A Randomized Trial to Evaluate OnabotulinumtoxinA for Prevention of Headaches in Adolescents With Chronic Migraine.

ABSTRACT: OBJECTIVE:As a post-approval commitment, this dose-ranging study was undertaken to evaluate efficacy and safety of onabotulinumtoxinA in adolescents. BACKGROUND:In adolescents, migraine is often undiagnosed or misdiagnosed and can present unique management challenges. OnabotulinumtoxinA was approved for prevention of chronic migraine (CM) in adults in 2010. METHODS:This multicenter, double-blind, parallel-group, randomized trial assessed a single treatment of onabotulinumtoxinA (155 U or 74 U) vs placebo (intramuscular saline) administered via the recommended fixed-dose fixed site paradigm in adolescents with CM aged 12 to <18 years. The primary efficacy measure was change in frequency of headache days from baseline at week 12; other measures included change in frequency of headache days at weeks 4 and 8 and change in frequency of severe headache days. Safety and tolerability were assessed. RESULTS:Of 125 randomized patients (onabotulinumtoxinA 155 U, n = 45; onabotulinumtoxinA 74 U, n = 43; placebo, n = 37), all were included in the primary efficacy analysis, and 115 (92.0%) completed the study. Lack of efficacy was the primary reason for discontinuing (n = 4; 3.2%); no patients discontinued because of adverse events. All treatments reduced frequency of headache days at week 12, with no significant differences between treatments. The mean (95% confidence interval) changes from baseline in the frequency of headache days during the 28-day period ending at week 12 (primary endpoint) were -6.3 (-8.5, -4.2), -6.4 (-8.8, -4.0), and -6.8 (-9.6, -4.1) days in the onabotulinumtoxinA 155 U, onabotulinumtoxinA 74 U, and placebo groups, respectively (P ? .474). All treatments reduced frequency of severe headache days and were well-tolerated; serious adverse events (n = 3) were considered unrelated to treatment and resolved without sequelae. The most commonly reported treatment-emergent adverse events were neck pain (n = 8), upper respiratory tract infection (n = 7), migraine, and nasopharyngitis (n = 5 each). CONCLUSION:Although this study did not meet its efficacy endpoints, onabotulinumtoxinA was well tolerated in this adolescent population. Given previous data demonstrating the benefits of onabotulinumtoxinA in adults with CM, additional studies with design modifications, including adequate statistical power, to assess the efficacy of multiple treatment cycles of onabotulinumtoxinA for CM prevention in adolescents may be informative.

Project description:Background and objectivesChronic headache disorders are a major cause of pain and disability. Education and supportive self-management approaches could reduce the burden of headache disability. We tested the effectiveness of a group educational and supportive self-management program for people living with chronic headaches.MethodsThis was a pragmatic randomized controlled trial. Participants were aged 18 years or older with chronic migraine or chronic tension-type headache, with or without medication overuse headache. We primarily recruited from general practices. Participants were assigned to either a 2-day group education and self-management program, a one-to-one nurse interview, and telephone support or to usual care plus relaxation material. The primary outcome was headache related-quality of life using the Headache Impact Test (HIT)-6 at 12 months. The primary analysis used intention-to-treat principles for participants with migraine and both baseline and 12-month HIT-6 data.ResultsBetween April 2017 and March 2019, we randomized 736 participants. Because only 9 participants just had tension-type headache, our main analyses were on the 727 participants with migraine. Of them, 376 were allocated to the self-management intervention and 351 to usual care. Data from 586 (81%) participants were analyzed for primary outcome. There was no between-group difference in HIT-6 (adjusted mean difference = -0.3, 95% CI -1.23 to 0.67) or headache days (0.9, 95% CI -0.29 to 2.05) at 12 months. The Chronic Headache Education and Self-management Study intervention generated incremental adjusted costs of £268 (95% CI, £176-£377) (USD383 [95% CI USD252-USD539]) and incremental adjusted quality-adjusted life years (QALYs) of 0.031 (95% CI -0.005 to 0.063). The incremental cost-effectiveness ratio was £8,617 (USD12,322) per QALY gained.DiscussionThese findings conclusively show a lack of benefit for quality of life or monthly headache days from a brief group education and supportive self-management program for people living with chronic migraine or chronic tension-type headache with episodic migraine.Trial registration informationRegistered on the International Standard Randomized Controlled Trial Number registry, ISRCTN79708100 16th December 2015 doi.org/10.1186/ISRCTN79708100. The first enrollment was April 24, 2017.Classification of evidenceThis study provides Class III evidence that a brief group education and self-management program does not increase the probability of improvement in headache-related quality of life in people with chronic migraine.

Project description:ImportanceVasoactive intestinal polypeptide (VIP) and pituitary adenylate cyclase-activating polypeptides (PACAPs) are structurally and functionally related, yet different in their migraine-inducing properties. It remains unclear whether the lack of migraine induction can be attributed to the only transient vasodilatory response after a 20-minute infusion of VIP.ObjectiveTo determine whether a 2-hour infusion of VIP would provoke migraine attacks.Design, setting, and participantsA randomized, double-blind, placebo-controlled, crossover study was conducted between May and September 2020 at the Danish Headache Center in Copenhagen, Denmark. Patients were eligible for inclusion if they were ages 18 to 40 years, weighed between 50 and 90 kg, had a diagnosis of migraine without aura as defined by the International Classification of Headache Disorders, and had a migraine frequency of 1 to 6 attacks per month.InterventionsPatients were randomly allocated to receive a 2-hour infusion of VIP or placebo on 2 different days.Main outcomes and measuresThe primary end point was the difference in incidence of experimentally induced migraine attacks during the observational period (0-12 hours) between VIP and placebo.ResultsTwenty-one patients (17 [81%] women and 4 [19%] men; mean [range] age, 25.9 [19-40] years) were recruited in the study. Fifteen patients (71%; 95% CI, 48%-89%) developed migraine attacks after VIP compared with 1 patient (5%; 95% CI, 0%-24%) who developed a migraine attack after placebo (P < .001). The VIP-induced migraine attacks mimicked patients' spontaneous attacks. The area under the curve (AUC) of headache intensity scores (0-12 hours), as well as the AUC of the superficial temporal artery diameter (0-180 minute) were significantly greater after VIP compared with placebo (AUC0-12h, P = .003; AUC0-180min, P < .001).Conclusions and relevanceA 2-hour infusion of VIP caused migraine attacks, suggesting an important role of VIP in migraine pathophysiology. VIP and its receptors could be potential targets for novel migraine drugs.Trial registrationClinicalTrials.gov Identifier: NCT04260035.

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:ObjectiveTo compare effectiveness of onabotulinumtoxinA and topiramate for chronic migraine (CM) prevention.BackgroundThe efficacy* of onabotulinumtoxinA and topiramate has been established in placebo-controlled randomized clinical trials (*defined as the benefit of treatment under ideal conditions). The effectiveness* of the 2 preventive treatments, however, has not been established (*the benefit of treatment under real-world conditions, representing a blend of efficacy and tolerability).MethodsIn this multicenter, randomized, parallel-group, post-authorization, open-label prospective study (FORWARD; ClinicalTrials.gov, NCT02191579), we randomized adults with CM (1:1) to onabotulinumtoxinA 155 U every 12 weeks for 3 cycles or topiramate "immediate release" 50-100 mg/day to week 36. Primary outcome measure was proportion of patients achieving ≥50% reduction in headache days (weeks 29-32). Missing values were imputed using baseline observation carried forward (BOCF) methodology. After 12 weeks, patients initially randomized to topiramate could cross over to onabotulinumtoxinA treatment. We monitored and recorded all adverse events (AEs).ResultsWe enrolled 282 patients (onabotulinumtoxinA, n = 140; topiramate, n = 142) and 148 patients completed randomized treatment (onabotulinumtoxinA, n = 120 [86%]; topiramate, n = 28 [20%]). Primary reasons for withdrawal were ineffective treatment (onabotulinumtoxinA, n = 7 [5%]; topiramate, n = 27 [19%]) and AEs (onabotulinumtoxinA, n = 5 [4%]; topiramate, n = 72 [51%]). Eighty topiramate patients crossed over to onabotulinumtoxinA. In the BOCF analysis, a significantly higher proportion of patients randomized to onabotulinumtoxinA experienced ≥50% reduction in headache frequency compared with those randomized to topiramate (40% [56/140] vs 12% [17/142], respectively; adjusted OR, 4.9 [95% CI, 2.7-9.1]; P < .001). OnabotulinumtoxinA was superior to topiramate in meeting secondary endpoints. In a post hoc analysis using observed data, the 50% responder rates at week 12 were 45.6% for onabotulinumtoxinA (n = 125) and 29.4% for topiramate (n = 109) (P = .015). AEs were reported by 48% (105/220) of onabotulinumtoxinA and 79% (112/142) of topiramate patients. Results were similar in those who crossed over to onabotulinumtoxinA.ConclusionsWhile using imputation methods of accounting for differences in discontinuation rates, we found onabotulinumtoxinA to have greater clinical utility than topiramate, largely because of tolerability issues associated with the latter and a relatively higher number of onabotulinumtoxinA patients remaining on treatment.

Project description:Early, safe, effective, and durable evidence-based interventions for children and adolescents with chronic migraine do not exist.To determine the benefits of cognitive behavioral therapy (CBT) when combined with amitriptyline vs headache education plus amitriptyline.A randomized clinical trial of 135 youth (79% female) aged 10 to 17 years diagnosed with chronic migraine (?15 days with headache/month) and a Pediatric Migraine Disability Assessment Score (PedMIDAS) greater than 20 points were assigned to the CBT plus amitriptyline group (n?=?64) or the headache education plus amitriptyline group (n?=?71). The study was conducted in the Headache Center at Cincinnati Children's Hospital between October 2006 and September 2012; 129 completed 20-week follow-up and 124 completed 12-month follow-up.Ten CBT vs 10 headache education sessions involving equivalent time and therapist attention. Each group received 1 mg/kg/d of amitriptyline and a 20-week end point visit. In addition, follow-up visits were conducted at 3, 6, 9, and 12 months.The primary end point was days with headache and the secondary end point was PedMIDAS (disability score range: 0-240 points; 0-10 for little to none, 11-30 for mild, 31-50 for moderate, >50 for severe); both end points were determined at 20 weeks. Durability was examined over the 12-month follow-up period. Clinical significance was measured by a 50% or greater reduction in days with headache and a disability score in the mild to none range (<20 points).At baseline, there were a mean (SD) of 21 (5) days with headache per 28 days and the mean (SD) PedMIDAS was 68 (32) points. At the 20-week end point, days with headache were reduced by 11.5 for the CBT plus amitriptyline group vs 6.8 for the headache education plus amitriptyline group (difference, 4.7 [95% CI, 1.7-7.7] days; P?=?.002). The PedMIDAS decreased by 52.7 points for the CBT group vs 38.6 points for the headache education group (difference, 14.1 [95% CI, 3.3-24.9] points; P?=?.01). In the CBT group, 66% had a 50% or greater reduction in headache days vs 36% in the headache education group (odds ratio, 3.5 [95% CI, 1.7-7.2]; P?<?.001). At 12-month follow-up, 86% of the CBT group had a 50% or greater reduction in headache days vs 69% of the headache education group; 88% of the CBT group had a PedMIDAS of less than 20 points vs 76% of the headache education group. Measured treatment credibility and integrity was high for both groups.Among young persons with chronic migraine, the use of CBT plus amitriptyline resulted in greater reductions in days with headache and migraine-related disability compared with use of headache education plus amitriptyline. These findings support the efficacy of CBT in the treatment of chronic migraine in children and adolescents.clinicaltrials.gov Identifier: NCT00389038.
