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:ObjectiveTo evaluate the efficacy of monthly or quarterly fremanezumab in patients with chronic migraine or episodic migraine and documented inadequate response to 2, 3, or 4 classes of prior migraine preventive medications.MethodsThis is an exploratory analysis of a randomized, double-blind, placebo-controlled, phase 3b trial for patients with chronic migraine or episodic migraine and inadequate response to 2 to 4 prior migraine preventive medication classes randomized (1:1:1) to fremanezumab (quarterly or monthly) or placebo. In this exploratory analysis, changes from baseline in the monthly average number of migraine days during 12 weeks of double-blind treatment and adverse events were evaluated for predefined subgroups of patients by number of prior preventive medication classes with inadequate response.ResultsOverall, 414, 265, and 153 patients had inadequate response to 2, 3, and 4 preventive medication classes, respectively. Changes from baseline in monthly average migraine days during 12 weeks were significantly greater with fremanezumab compared with placebo for patients with documented inadequate response to 2 classes (least-squares mean difference vs placebo [95% confidence interval]: quarterly, -2.9 [-3.83, -1.98]; monthly, -3.7 [-4.63, -2.75]), 3 classes (quarterly, -3.3 [-4.65, -1.95]; monthly, -3.0 [-4.25, -1.66]), and 4 classes (quarterly, -5.3 [-7.38, -3.22]; monthly, -5.4 [-7.35, -3.48]) of migraine preventive medications (all p < 0.001). No significant treatment-by-subgroup interactions were observed for any outcome (p interaction > 0.20 for all). Adverse events were comparable for placebo and fremanezumab.ConclusionSignificant improvements in efficacy were observed with fremanezumab compared with placebo, even in patients who had previously experienced inadequate response to 4 different classes of migraine preventive medications.ClinicalTrials.gov identifier: NCT03308968.

Project description:An intramuscular formulation of onabotulinumtoxinA (onabotA; Botox®) is currently the only therapy specifically approved for the prevention of headaches in adults with chronic migraine (CM) in the EU and North America. This article provides a narrative review of relevant data on the drug in this indication from an EU perspective. OnabotA was originally approved on the basis of pooled data from two phase III studies (PREEMPT 1 and 2). In these pivotal studies, injection of up to five cycles of onabotA (155-195 U/cycle) at 12-week intervals was generally well tolerated and effective in producing statistically significant and clinically meaningful improvements in headache symptoms, acute headache pain medication usage, headache impact and health-related quality of life in adults with CM, of whom approximately two-thirds were acute medication overusers and approximately one-third had failed to respond to???3 prior oral prophylactic therapies. More recently, the efficacy and tolerability of onabotA over a period of 1 year in the PREEMPT programme has been substantiated and extended by the results of a long-term phase IV study (COMPEL), in which patients received up to nine treatment cycles over a period of 2 years, and by findings from several real-world clinical practice studies from Europe, including the prospective multinational REPOSE and CM-PASS studies. In conclusion, the totality of evidence from clinical trials and real-world studies indicates that onabotA is an effective and generally well tolerated option for the prevention of CM that may be particularly useful for patients who have previously failed to respond to or are intolerant of commonly prescribed oral prophylactics.

Project description:OnabotulinumtoxinA (Botox®; a formulation of botulinum toxin type A (BoNT/A)] is indicated for the prevention of headaches in adults with chronic migraine (CM) in numerous countries, including those of Europe. In clinical trials, intramuscular administration of BoNT/A (155-195 units at 12-week intervals) to patients with CM was generally well tolerated and associated with sustained and clinically meaningful improvements in multiple assessments of headache symptoms, headache-related impact and/or disability and migraine-specific health-related quality of life over a period of 1 year (in the pivotal PREEMPT 1 and 2 studies) and 2 years (in the phase IV COMPEL study). The efficacy and safety of BoNT/A therapy have been confirmed in a number of large, prospective, real-world studies conducted in Europe, including the 2-year REPOSE study. Intramuscular BoNT/A has also demonstrated greater clinical utility than the oral prophylactic medication topiramate in a clinical practice setting (FORWARD study).

Project description:BackgroundThe relationship between physical activity (PA) and migraine is insufficiently understood. Studies have not analysed levels of PA or Time Sitting (TS) during preventive treatment, nor the role these might play in the response to preventive treatment.MethodsAn observational, longitudinal prospective study in a headache clinic was conducted. All consecutive chronic migraine patients initiating fremanezumab were invited to participate and were followed for three visits. The International Physical Activity Questionnaire (IPAQ) - long version was used.ResultsSeventy-six patients with a median of 46 years old, 84.2% female were enrolled. One month after fremanezumab administration, there was a significant increase of most PA variables and a significant decrease in TS levels compared with baseline; headache days and walking, TS and migraine days showed a moderate correlation. Three months after initiation, all PA variables statistically increased and TS levels statistically decreased, and variables such as headache/migraine days showed a moderate correlation with all PA variables analysed. In the multivariate analysis, higher levels of walking at baseline were independently associated with response to fremanezumab (ORa: 1.194; CI: 1.018-1.401, p = 0.029).ConclusionPatients who spent more time walking before starting treatment, were more likely to have a response to fremanezumab. PA and TS levels changed since the first month and correlated with clinical variables.

Project description:BackgroundChronic migraine (CM) is associated with substantial economic burden. Real-world data suggests that onabotulinumtoxinA treatment for CM reduces healthcare resource utilisation (HRU) and related costs.MethodsREPOSE was a 2-year prospective, multicentre, non-interventional, observational study to describe the real-world use of onabotulinumtoxinA in adult patients with CM. This analysis examined the impact of onabotulinumtoxinA on HRU. Patients received onabotulinumtoxinA treatment approximately every 12 weeks according to their physicians' discretion, guided by the summary of product characteristics (SPC) and PREEMPT injection paradigm. HRU outcome measures were collected at baseline and all administration visits and included headache-related hospitalizations and healthcare professional (HCP) visits. Health economic data, including family doctor and specialist visits, inpatient treatment for headache, acupuncture, technical diagnostics, use of nonpharmacologic remedies, and work productivity were also collected for patients enrolled at German study centres.ResultsOverall, 641 patients were enrolled at 78 study centres across 7 countries (Germany, UK, Italy, Spain, Norway, Sweden, and Russia), 633 received ≥1 onabotulinumtoxinA dose, and 128 completed the 2-year study. Patients were, on average, aged 45 years, 85% were female, and 60% (n = 377) were from Germany. At the end of the 2-year observation period, significantly fewer patients reported headache-related hospitalizations (p < 0.02) and HCP visits (p < 0.001) within the past 3 months than in the 3 months before baseline. In the German population, reductions were observed across all health services at all follow-up visits compared with baseline. The percentage of patients who saw a family doctor decreased from 41.7% at baseline to 13.5% at administration visit 8 and visits to a medical specialist decreased from 61.7% to 5.2% of patients. Inpatient acute treatment and technical diagnostics declined from 6.4% and 19.7% of patients at baseline to 0.0% and 1.0% at administration 8, respectively. The use of nonpharmacologic remedies and medication for the acute treatment of migraine also decreased with continued onabotulinumtoxinA treatment. Work incapacity, disability, absenteeism, and impaired performance at school/work improved with onabotulinumtoxinA treatment for CM over the 2-year observation period.ConclusionsReal-world evidence from REPOSE demonstrates that onabotulinumtoxinA treatment is associated with decreased HRU and supports the long-term benefits associated with the use of onabotulinumtoxinA for CM in clinical practice.Trial registrationNCT01686581 .

Project description:Introduction/objectiveChronic 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.MethodsFORWARD 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).ResultsA 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).ConclusionOnabotulinumtoxinA 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.Trial registration: clinicaltrials.govNCT02191579; https://clinicaltrials.gov/ct2/show/NCT02191579.

Project description:BackgroundFremanezumab, a fully humanized monoclonal antibody (IgG2Δa) selectively targets the calcitonin gene-related peptide and has proven efficacy for the preventive treatment of migraine. In this study, we evaluated the long-term efficacy, safety, and tolerability of monthly and quarterly fremanezumab.MethodsEpisodic migraine and chronic migraine patients completing the 12-week double-blind period of the FOCUS trial entered the 12-week open-label extension and received 3 monthly doses of fremanezumab (225 mg). Changes from baseline in monthly migraine days, monthly headache days of at least moderate severity, days of acute headache medication use, days with photophobia/phonophobia, days with nausea or vomiting, disability scores, and proportion of patients achieving a ≥50% or ≥75% reduction in monthly migraine days were evaluated.ResultsOf the 807 patients who completed the 12-week double-blind treatment period and entered the open-label extension, 772 patients completed the study. In the placebo, quarterly fremanezumab, and monthly fremanezumab dosing regimens, respectively, patients had fewer average monthly migraine days (mean [standard deviation] change from baseline: - 4.7 [5.4]; - 5.1 [4.7]; - 5.5 [5.0]), monthly headache days of at least moderate severity (- 4.5 [5.0]; - 4.8 [4.5]; - 5.2 [4.9]), days per month of acute headache medication use (- 4.3 [5.2]; - 4.9 [4.6]; - 4.8 [4.9]), days with photophobia/phonophobia (- 3.1 [5.3]; - 3.4 [5.3]; - 4.0 [5.2]), and days with nausea or vomiting (- 2.3 [4.6]; - 3.1 [4.5]; - 3.0 [4.4]). During the 12-week open-label extension, 38%, 45%, and 46% of patients, respectively, achieved a ≥50% reduction and 16%, 15%, and 20%, respectively, achieved a ≥75% reduction in monthly migraine days. Disability scores were substantially improved in all 3 treatment groups. There were low rates of adverse events leading to discontinuation (<1%).ConclusionFremanezumab demonstrated sustained efficacy up to 6 months and was well tolerated in patients with episodic migraine or chronic migraine and documented inadequate response to multiple migraine preventive medication classes.Trial registrationClinicalTrials.gov NCT03308968 (FOCUS).

Project description:BackgroundAnatomical and experimental data indicate that onabotulinimtoxin A could be more efficient and cost-effective for treating chronic migraine with injections targeting the cranial sutures, where collaterals from the meninges penetrate the skull.MethodsA new injection paradigm (FollowTheSutures) was tested for safety, tolerability and feasibility in a Phase II, open-label, non-controlled, single-center pilot study. Ninety units of onabotulinimtoxin A (Botox®), were injected in 18 sites over the area of the cranial sutures. Adverse events and potential beneficial effects were recorded in a headache diary at least 4 weeks before, and for 12 weeks after the injections. A higher dilution than normal of onabotulinimtoxin A was used to get better diffusion.ResultsNineteen (of 20 included) women with chronic migraine received the injections and were evaluable. There was only one treatment-related adverse event (reduced power of chewing for some weeks). Otherwise, the procedure was overall well tolerated. Patients improved on most efficacy parameters after the injections. There was little or no effect on glabellar or forehead lines.ConclusionsThe protocol was safe and well tolerated. Lower risk of unblinding due to the absence of cosmetic effects should make the injection procedure well suited for a large, randomized, placebo-controlled study. If efficacy is confirmed, it will be markedly less costly than the standard procedure.Trial registration: EUDRACT (2017-002516-13), ClinicalTrials.gov (NCT03543254).

Project description:BackgroundThe FOCUS study evaluated the efficacy of migraine preventive medications across different countries within the same patient population, particularly for patients with difficult-to-treat migraine. These prespecified subgroup analyses evaluated efficacy by country in the FOCUS study of fremanezumab in adults with episodic migraine or chronic migraine and documented inadequate response to 2 to 4 migraine preventive medication classes.MethodsOverall, 838 participants were enrolled in the FOCUS study, a randomized, double-blind, placebo-controlled, parallel-group, phase 3b study performed at 104 sites. For 12 weeks of double-blind treatment, patients were randomized (1:1:1) to quarterly fremanezumab, monthly fremanezumab, or matched placebo. The primary efficacy endpoint was the mean change from baseline in monthly average migraine days over 12 weeks of double-blind treatment, evaluated by country in these subgroup analyses.ResultsOf 14 countries contributing data, the Czech Republic (n = 188/838; 22%), the United States (n = 120/838; 14%), and Finland (n = 85/838; 10%) enrolled the most patients. Changes from baseline in monthly average migraine days over 12 weeks were significantly greater with fremanezumab versus placebo for patients in these countries: Czech Republic (least-squares mean difference versus placebo [95% confidence interval]: quarterly fremanezumab, - 1.9 [- 3.25, - 0.47]; P = 0.009; monthly fremanezumab, - 3.0 [- 4.39, - 1.59]; P < 0.001), the United States (quarterly fremanezumab, - 3.7 [- 5.77, - 1.58]; P < 0.001; monthly fremanezumab, - 4.2 [- 6.23, - 2.13]; P < 0.001), and Finland (quarterly fremanezumab, - 3.0 [- 5.32, - 0.63]; P = 0.014; monthly fremanezumab, - 3.9 [- 6.27, - 1.44]; P = 0.002). Results were comparable for the remaining 9 countries, with the least-squares mean difference versus placebo ranging from - 5.6 to - 2.4 with quarterly fremanezumab and from - 5.3 to - 1.5 with monthly fremanezumab. Incidences of serious adverse events and adverse events leading to discontinuation were low and comparable across countries and treatment groups.ConclusionsMonthly and quarterly fremanezumab significantly reduced the monthly average number of migraine days versus placebo regardless of country and continent (North America versus Europe) in migraine patients with documented inadequate response to 2 to 4 migraine preventive medication classes.Trial registrationClinicalTrials.gov Identifier: NCT03308968 .
