Objective: To assess the burden and consequences of migraine in Brazil in terms of health‐related quality of life (HRQoL), work productivity and daily activities, and healthcare resource utilization (HRU). Background: Despite existing data on how migraine affects populations worldwide, there are limited data on the burden of migraine in Latin America. Methods: This cross‐sectional study used patient‐reported data from the 2018 Brazil National Health and Wellness Survey. HRQoL scores (EuroQol 5‐dimension 5‐level [EQ‐5D‐5L]; 36‐item Short Form Health Survey, version 2 [SF‐36v2]; and Short Form 6‐dimension [SF‐6D]), impairments to work productivity and daily activities (Work Productivity and Activity Impairment questionnaire), and all‐cause HRU were compared between migraine respondents and matched non‐migraine controls. Results: Of the 12,000 total respondents in the survey database, 1643 self‐reported a physician diagnosis of migraine and were propensity score matched 1:1 with controls without migraine. HRQoL was lower in patients with migraine versus non‐migraine controls, with significantly lower SF‐36v2 physical (mean [± SD] 50.3 [7.5] vs. 52.0 [7.6]) and mental component (mean [± SD] 42.9 [10.2] vs. 46.0 [9.9]) summary scores and SF‐6D (mean [± SD] 0.7 [0.1] vs. 0.7 [0.1]) and EQ‐5D‐5L (mean [± SD] 0.7 [0.2] vs. 0.8 [0.2]) utility scores (all p < 0.001). Patients with migraine reported higher levels of work productivity loss (mean [± SD], 40.6% [31.4%] vs. 28.6% [30.9%], including absenteeism 12.8% [19.1%] vs. 8.4% [17.1%] and presenteeism 35.0% [28.7%] vs. 24.8% [28.0%]; all p < 0.001); activity impairment (mean [± SD] 36.0% [28.8%] vs. 25.5% [28.1%]; p < 0.001); and significantly higher HRU in the past 6 months (healthcare provider and emergency department visits [mean [± SD] 7.2 [9.5] vs. 4.5 [6.3] and 1.7 [3.8] vs. 0.9 [2.2]; both p < 0.001] and hospitalizations [mean [± SD] 0.4 [2.7] vs. 0.2 [1.1]; p = 0.002]) than controls. Conclusion: Migraine is associated with poorer HRQoL, higher all‐cause HRU, and greater activity impairment and work productivity loss versus non‐migraine controls in Brazil. [ABSTRACT FROM AUTHOR]

Background: Migraine is the second leading cause of disability worldwide. Although many preventive treatments reduce migraine frequency and severity, it is unclear whether these treatments reduce migraine-related disability in a clinically meaningful way. This pooled analysis evaluated the ability of fremanezumab to reduce migraine-related disability, based on responses and shifts in severity in patient-reported disability outcomes. Methods: This pooled analysis included 3 double-blind phase 3 trials (HALO EM, HALO CM, FOCUS) in which patients with episodic or chronic migraine were randomly assigned 1:1:1 to quarterly or monthly fremanezumab or matched placebo for 12 weeks. Migraine-related disability was assessed using the 6-item Headache Impact Test (HIT-6) and Migraine Disability Assessment (MIDAS) questionnaires. A clinically meaningful improvement in disability was defined per American Headache Society guidelines: for HIT-6, a ≥ 5-point reduction; for MIDAS, a ≥ 5-point reduction when baseline score was 11 to 20 or ≥ 30% reduction when baseline score was > 20. Proportions of patients who demonstrated shifts in severity for each outcome were also evaluated. Results: For patients with baseline MIDAS scores of 11 to 20 (n = 234), significantly higher proportions achieved 5-point reductions from baseline in MIDAS scores with fremanezumab (quarterly, 71%; monthly, 70%) compared with placebo (49%; both P ≤ 0.01). For patients with baseline MIDAS scores of > 20 (n = 1266), proportions achieving ≥30% reduction from baseline in MIDAS scores were also significantly higher with fremanezumab (quarterly, 69%; monthly, 79%) compared with placebo (58%; both P < 0.001). For HIT-6 scores, proportions of patients achieving 5-point reductions from baseline were significantly higher with fremanezumab (quarterly, 53%; monthly, 55%) compared with placebo (39%; both P < 0.0001). Proportions of patients with shifts of 1 to 3 grades down in MIDAS or HIT-6 disability severity were significantly greater with quarterly and monthly fremanezumab compared with placebo (all P < 0.0001). Conclusion: Fremanezumab demonstrated clinically meaningful improvements in disability severity in this pooled analysis. Trial registrations: HALO CM, NCT02621931; HALO EM, NCT02629861; FOCUS, NCT03308968. [ABSTRACT FROM AUTHOR]

Background: Fremanezumab, a fully humanized monoclonal antibody (mAb; IgG2Δa) that selectively targets calcitonin gene-related peptide (CGRP), is approved for the preventive treatment of migraine in adults. The efficacy and safety of fremanezumab for migraine prevention have been demonstrated in randomized, double-blind, placebo-controlled trials. Real-world effectiveness data are needed to complement clinical trial data. This study assessed the effectiveness of fremanezumab across different subgroups of adult patients with episodic migraine (EM), chronic migraine (CM), or difficult-to-treat (DTT) migraine in real-world clinical settings. Methods: This retrospective, panel-based online chart review used electronic case report forms. Patient inclusion criteria were a physician diagnosis of EM or CM; age ≥ 18 years at the time of first fremanezumab initiation; ≥ 1 dose of fremanezumab treatment; ≥ 1 follow-up visit since first initiation; and ≥ 2 measurements of monthly migraine days (MMD; with 1 within a month before or at first initiation and ≥ 1 after first initiation). Changes in MMD and monthly headache days were assessed during the follow-up period. These endpoints were evaluated in subgroups of patients by migraine type (EM/CM) and in subgroups with DTT migraine (diagnosis of medication overuse [MO], major depressive disorder [MDD], generalized anxiety disorder [GAD], or prior exposure to a different CGRP pathway–targeted mAb [CGRP mAb]). Results: Data were collected from 421 clinicians and 1003 patients. Mean (percent) reductions from baseline in MMD at Month 6 were − 7.7 (77.0%) in EM patients, − 10.1 (68.7%) in CM patients, − 10.8 (80.6%) in the MO subgroup, − 9.9 (68.3%) in the MDD subgroup, − 9.5 (66.4%) in the GAD subgroup, and − 9.0 (68.7%) in the prior CGRP mAb exposure subgroup. Improvements in MDD or GAD severity were reported by 45.5% and 45.8% of patients with comorbid MDD or GAD, respectively. Conclusions: In this real-world study, fremanezumab demonstrated effectiveness for migraine regardless of migraine type or the presence of factors contributing to DTT migraine (MO, GAD, MDD, or prior exposure to a different CGRP mAb).

Background: Following approval of fremanezumab for the prevention of migraine in adults, health care decision makers are interested in understanding real-world clinical characteristics and treatment patterns among patients initiating fremanezumab therapy. Methods: Data were obtained for this retrospective (pre-post) study from the Veradigm Health Insights database. The study period was January 1, 2014, to June 30, 2019. Patients were included if they were aged ≥ 18 years; had ≥ 1 migraine diagnosis during the study period; and had a medication record for fremanezumab on or after diagnosis during the identification period (September 1, 2018–December 31, 2018). Treatment patterns, including adherence, persistence, and utilization of acute and preventive migraine medication prescriptions, were evaluated. Results: Of 987 patients initiating fremanezumab during the study period, 738 (74.8%) were adherent to fremanezumab by proportion of days covered (PDC; ≥ 80%) and 780 (79.0%) were adherent by medication possession ratio (MPR; ≥ 80%). A total of 746 (75.6%) patients were persistent for ≥ 6 months. Quarterly fremanezumab (n = 186) was associated with higher rates of adherence versus monthly fremanezumab (n = 801) by PDC (quarterly, 91.3%; monthly, 84.9%; P < 0.001) and MPR (quarterly, 92.2%; monthly, 87.9%; P = 0.006) and higher persistence at ≥ 6 months (quarterly, 82.8%; monthly, 73.9%; P = 0.011). After fremanezumab initiation, patients who were persistent for ≥ 6 months experienced significant reductions from baseline in the mean monthly number of acute and preventive migraine medication prescriptions (P < 0.001). Subgroup analyses in patients with comorbid depression and anxiety showed meaningful real-world benefits based on significant reductions in the number of patients who were prescribed antidepressants (baseline, 68.6%; follow-up, 56.4%; P = 0.0025) and anxiolytic medications (baseline, 55.0%; follow-up, 47.2%; P = 0.037), respectively. In a subgroup of patients with comorbid hypertension at baseline, fremanezumab treatment resulted in nonsignificant reductions in blood pressure. Conclusions: Overall, adherence and persistence to fremanezumab in this real-world study was high in patients with migraine, with higher rates observed for quarterly fremanezumab. Patients who were persistent for ≥ 6 months experienced significant reductions in acute and preventive migraine medication use, while a subgroup of migraine patients with comorbid depression and anxiety at baseline showed significant reductions in antidepressant and anxiolytic medication use.

Background: Although migraine is less common in older people, preventive treatment of migraine in these individuals may be more challenging due to the presence of multiple comorbidities and polypharmacy. Additionally, evidence for migraine treatment efficacy, safety, and tolerability is limited in this population. We evaluated efficacy, safety, and tolerability of fremanezumab, a fully humanized monoclonal antibody (IgG2Δa) that selectively targets calcitonin gene–related peptide (CGRP), in clinical trial participants aged ≥60 years with episodic migraine (EM) or chronic migraine (CM). Methods: This analysis included data from 3 randomized, double-blind, placebo-controlled phase 3 studies: the HALO EM study, HALO CM study, and FOCUS study in participants with EM or CM and prior inadequate response to 2–4 migraine preventive medication classes. Participants in all studies were randomized 1:1:1 to receive 12 weeks of subcutaneous treatment with quarterly fremanezumab (Months 1/2/3: EM/CM, 675 mg/placebo/placebo), monthly fremanezumab (Months 1/2/3: EM, 225 mg/225 mg/225 mg; CM, 675 mg/225 mg/225 mg), or matched monthly placebo. Results: These pooled analyses included 246 participants aged ≥60 years. Reductions in monthly migraine days from baseline over 12 weeks were significantly greater with fremanezumab (least-squares mean change from baseline [standard error]: quarterly fremanezumab, − 4.3 [0.59]; monthly fremanezumab, − 4.6 [0.54]) versus placebo (placebo, − 2.3 [0.57]; both P < 0.01 vs placebo). As early as Week 1, significant reductions from baseline in weekly migraine days were observed with fremanezumab versus placebo (both P < 0.01). With fremanezumab treatment versus placebo, a significantly higher proportion of participants achieved ≥50% reduction in monthly migraine days, and significant improvements in disability and quality-of-life outcomes were observed (P < 0.05). Proportions of participants experiencing serious adverse events and adverse events leading to discontinuation were low and similar in the fremanezumab and placebo groups. Efficacy and safety results were comparable to the overall pooled population (N = 2843). Conclusions: This pooled subgroup analysis demonstrates that fremanezumab treatment is efficacious and well-tolerated over 12 weeks in participants aged ≥60 years with EM or CM. These data may help healthcare providers with clinical decision making and preventive treatment selection for older patients with migraine.

Objective: To 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.Methods: This 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.Results: Overall, 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.Conclusion: Significant 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.

Background: Fremanezumab, 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. Methods: Episodic 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. Results: Of 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%). Conclusion: Fremanezumab 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 registration: ClinicalTrials.gov NCT03308968 (FOCUS). [ABSTRACT FROM AUTHOR]

Objective: To evaluate whether quarterly or monthly administration of fremanezumab for migraine prevention exhibits a pattern of decreased efficacy toward the end of the dosing interval (wearing‐off effect). Background: The main goals of migraine preventive treatment are to reduce the frequency, severity, and duration of migraine attacks, and migraine‐associated disability. Wearing‐off refers to the phenomenon whereby clinical symptoms return or worsen before the next dose of a drug is due and has been reported previously with migraine preventive medications. Design and Methods: This was a long‐term, 12‐month, multicenter, randomized, double‐blind, parallel‐group phase 3 study (NCT02638103) that included chronic (CM) and episodic migraine (EM) patients who rolled over from the 12‐week phase 3 HALO CM (NCT02621931) and EM trials (NCT02629861), as well as an additional subset of 312 new patients. Patients with CM or EM received fremanezumab either monthly or quarterly. In this post hoc analysis, for selected months, the difference in the average number of migraine days between weeks 1‐2 and weeks 3‐4, between weeks 1‐3 and week 4, and between weeks 1‐2 and weeks 11‐12 were calculated. Results: A total of 1890 patients (CM, 1110; EM, 780) were enrolled. At months 3, 6, 9, and 15, there were no substantial differences in mean weekly migraine days between weeks 1‐2 and weeks 3‐4 or between weeks 1‐3 and week 4 with quarterly or monthly fremanezumab in the CM or EM subgroups. There were no substantial increases in mean weekly migraine days between weeks 1‐2 and weeks 11‐12 during the first quarter of treatment (months 1‐3) or the second quarter of treatment (months 4‐6) with quarterly or monthly fremanezumab in the CM or EM subgroups. Across both dosing subgroups in CM and EM patients, the mean weekly number of migraine days decreased substantially (30%‐42%) during the first 2 weeks; decreases in weekly migraine days remained steady during the last 2 weeks of the first quarter, with a similar maintenance of response during the second quarter. Conclusions: This analysis of data from a long‐term, phase 3 study showed that patients receiving quarterly fremanezumab or monthly fremanezumab did not experience a wearing‐off effect toward the end of the dosing interval.

Objective: Presentation of pooled analysis of safety data for fremanezumab in patients with chronic (CM) or episodic migraine (EM) from 4 placebo‐controlled phase 2b and phase 3 studies. Background: There is a need for an effective, safe, and well‐tolerated preventive therapy that specifically targets the pathophysiology of migraine to reduce the frequency and severity of migraine attacks in patients with CM or EM who experience 4 or more migraine days per month. Fremanezumab is a fully humanized monoclonal antibody that targets calcitonin gene‐related peptide, a neuropeptide involved in the pathophysiology of migraine. Design/Methods: The 4 placebo‐controlled phases 2b and 3 studies included in this analysis were 16‐week, multicenter, randomized, double‐blind, placebo‐controlled, and parallel‐group studies consisting of a screening visit, a 28‐day pretreatment baseline period, and a 12‐week treatment period with a final evaluation 4 weeks after the final dose of the study drug. Safety endpoints included adverse events (AEs) and immunogenicity. Results: A total of 2566 patients were randomized across all studies (fremanezumab, n = 1704; placebo, n = 862), and 2563 patients were treated. Common reasons for study discontinuation were withdrawal by patient (n = 78), patient lost to follow‐up (n = 60), and AE (n = 50). The mean (standard deviation) duration of exposure was 83.8 (13.6) days for the patients who received fremanezumab, with a total exposure of 390.4 patient years and maximum exposure of 181 days. AEs were mostly mild to moderate in severity and were reported among 48‐69% of patients in all treatment groups, and most were injection site reactions (pain, induration, and erythema). Two deaths occurred (chronic obstructive pulmonary disease and intentional overdose of diphenhydramine), both of which were deemed unrelated to study drug by the investigators and sponsor. Cardiovascular adverse events, abnormal liver function tests, and hypersensitivity were uncommon and occurred at similar rates between the placebo and fremanezumab groups. Conclusions: Fremanezumab is a generally safe and well‐tolerated preventive therapy for migraine in adults. [ABSTRACT FROM AUTHOR]

Background: We evaluated the efficacy of fremanezumab, a fully humanized monoclonal antibody that selectively targets calcitonin gene-related peptide, in patients with chronic migraine (CM) with and without medication overuse (MO). Methods: In a 12-week, phase 3 trial, patients with CM were randomized to fremanezumab quarterly (675 mg/placebo/placebo), monthly (675 mg/225 mg/225 mg), or placebo. Post hoc analyses assessed the impact of fremanezumab in patients with and without MO (monthly use of acute headache medication ≥15 days, migraine-specific acute medication ≥10 days, or combination medication ≥10 days) on efficacy outcomes, including headache days of at least moderate severity (HDs), and six-item Headache Impact Test (HIT-6) and Migraine-Specific Quality of Life (MSQoL) questionnaire scores. Results: Of 1130 patients enrolled, 587 (51.9%) had baseline MO. Fremanezumab reduced placebo-adjusted least-squares mean (95% confidence interval) monthly HDs (− 2.2 [− 3.1 to − 1.2] and − 2.7 [− 3.7 to − 1.8]; P < 0.0001) in patients with MO and without MO (quarterly − 1.4 [− 2.3 to − 0.5], P = 0.0026; monthly − 1.4 [− 2.3 to − 0.6], P = 0.0017). Significantly more fremanezumab-treated patients had ≥ 50% reduction in HDs versus placebo, regardless of baseline MO (with: quarterly 70/201 [34.8%], monthly 78/198 [39.4%] vs placebo 26/188 [13.8%]; without: quarterly 71/174 [40.8%], monthly 75/177 [42.4%] vs placebo 41/183 [22.4%]). Fremanezumab improved HIT-6 and MSQoL scores. Significantly more fremanezumab-treated patients reverted to no MO (quarterly 111/201 [55.2%], monthly 120/198 [60.6%]) versus placebo (87/188 [46.3%]). Conclusions: Fremanezumab is effective for prevention of migraine in patients with CM, regardless of MO, and demonstrated a benefit over placebo in reducing MO.

Background: The long-term safety and efficacy of fremanezumab were evaluated in a 52-week extension study (NCT02638103). Patient satisfaction with fremanezumab, dosing preferences, and patient-reported outcomes were assessed in a subpopulation who completed the extension study and consented to a follow-up questionnaire. Methods: In the extension study (N = 1842), adults with migraine were randomized to quarterly or monthly fremanezumab. After completing active treatment, patients answered a survey evaluating patient satisfaction, treatment and dosing preferences, and changes in patient-reported outcomes. Results: Of the 557 patients who could have been contacted upon completing the extension study, 302 consented and 253 completed the survey. The mean (standard deviation) satisfaction rating for fremanezumab was 6.1 (1.4; 1 = "extremely dissatisfied" to 7 = "extremely satisfied"). Most patients (175 [69.2%]) preferred quarterly over monthly fremanezumab dosing. Among patients taking antiepileptics (most common class of prior preventive medication; n = 130), 91.5% preferred fremanezumab. Patients reported improvements in anxiety (74 [67.9%]), sleep quality (143 [56.5%]), and quality of time spent with others (210 [83.0%]) with fremanezumab. Conclusion: In this study, treatment satisfaction with fremanezumab was high, most patients preferred quarterly fremanezumab dosing, and fremanezumab was generally preferred to prior preventive medications.

Background: Antibodies targeting calcitonin gene-related peptide (CGRP) or its receptor have shown efficacy in the prevention of migraine attacks. We investigated the efficacy and tolerability of fremanezumab, a fully humanised CGRP antibody, in patients with migraine who had previously not responded to two to four classes of migraine preventive medications.Methods: The randomised, double-blind, placebo-controlled, parallel-group, phase 3b FOCUS trial was done at 104 sites (including hospitals, medical centres, research institutes, and group practice clinics) across Belgium, the Czech Republic, Denmark, Finland, France, Germany, Italy, the Netherlands, Poland, Spain, Sweden, Switzerland, the UK, and the USA. We enrolled participants aged 18-70 years with episodic or chronic migraine who had documented failure to two to four classes of migraine preventive medications in the past 10 years. Failure was defined as no clinically meaningful improvement after at least 3 months of therapy at a stable dose, as per the treating physician's judgment; discontinuation because of adverse events that made treatment intolerable; or treatment contraindicated or unsuitable for the preventive treatment of migraine for the patient. Participants were randomly assigned (1:1:1) by electronic interactive response technology to subcutaneously administered quarterly fremanezumab (month 1, 675 mg; months 2 and 3: placebo), monthly fremanezumab (month 1: 225 mg in episodic migraine and 675 mg in chronic migraine; months 2 and 3: 225 mg in both migraine subgroups), or matched monthly placebo for 12 weeks. The primary outcome was mean change from baseline in the monthly average number of migraine days during the 12-week treatment period. This trial is registered with ClinicalTrials.gov, number NCT03308968, and is now completed.Findings: Between Nov 10, 2017, and July 6, 2018, 838 participants with episodic (329 [39%]) or chronic (509 [61%]) migraine were randomly assigned to placebo (n=279), quarterly fremanezumab (n=276), or monthly fremanezumab (n=283). Reductions from baseline in monthly average migraine days over 12 weeks were greater versus placebo (least-squares mean [LSM] change -0·6 [SE 0·3]) with quarterly fremanezumab (LSM change -3·7 [0·3]; LSM difference vs placebo -3·1 [95% CI -3·8 to -2·4]; p<0·0001) and with monthly fremanezumab (LSM change -4·1 [0·34]; LSM difference vs placebo -3·5 [-4·2 to -2·8]; p<0·0001). Adverse events were similar for placebo and fremanezumab. Serious adverse events were reported in four (1%) of 277 participants with placebo, two (<1%) of 276 with quarterly fremanezumab, and four (1%) of 285 with monthly fremanezumab.Interpretation: Fremanezumab was effective and well tolerated in patients with difficult-to-treat migraine who had previously not responded to up to four classes of migraine preventive medications.Funding: Teva Pharmaceuticals.
