BackgroundMigraine prevalence is age and sex dependent, predominating in women in early and middle adulthood; however, migraine also represents a substantial burden for men and adults of all ages. Thus, understanding this burden and the efficacy of migraine preventive medications in both sexes and across age groups is critical. The randomized, placebo-controlled, double-blind, phase 3b FOCUS study demonstrated the safety and efficacy of fremanezumab, a fully humanized monoclonal antibody (IgG2∆a) that selectively targets calcitonin gene-related peptide as a migraine preventive treatment for individuals with migraine and prior inadequate response to 2 to 4 migraine preventive medication classes. Here, we assessed the efficacy of fremanezumab in participants from FOCUS subgrouped by age (18–45 years and > 45 years) and sex.MethodsIn the FOCUS study, eligible participants were randomized (1:1:1) to 12 weeks of double-blind treatment with quarterly fremanezumab, monthly fremanezumab, or matched monthly placebo. In this post hoc analysis, we evaluated changes from baseline in monthly migraine days (primary endpoint of FOCUS) and other secondary and exploratory efficacy outcomes in prespecified age (18–45 and > 45 years) and sex subgroups.ResultsThe modified intention-to-treat population (received ≥ 1 dose of study drug and had ≥ 10 days of postbaseline efficacy assessments for the primary endpoint) totaled 837 participants (18–45 years, n = 373; > 45 years, n = 464; male, n = 138; female, n = 699). Consistent reductions in monthly average number of migraine days during 12 weeks were observed, regardless of age (18–45 years: quarterly fremanezumab, − 4.1 days; monthly fremanezumab, − 4.7 days; placebo, − 0.9 days; P < 0.001; > 45 years: quarterly fremanezumab, − 3.6 days; monthly fremanezumab, − 3.7 days; placebo, − 0.3 days; P < 0.001) and sex (male: quarterly fremanezumab, − 4.1 days; monthly fremanezumab, − 4.6 days; placebo, − 0.3 days; P < 0.001; female: quarterly fremanezumab, − 3.6 days; monthly fremanezumab, − 3.9 days; placebo, − 0.6 days; P < 0.001). Fremanezumab also reduced monthly headache days of at least moderate severity, monthly days of acute medication use, and improved Migraine Disability Assessment scores across subgroups.ConclusionsThese results demonstrate the efficacy of fremanezumab in patients with difficult-to-treat migraine for reducing migraine and headache days, acute medication use, and disability, regardless of age or sex.Trial registrationClinicalTrials.gov Identifier (FOCUS), registered October 13, 2017.Supplementary InformationThe online version contains supplementary material available at 10.1186/s10194-021-01336-1.

BackgroundAlthough 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).MethodsThis 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.ResultsThese 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).ConclusionsThis 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.Trial registrationClinicalTrials.gov identifiers: HALO CM: ; HALO EM: NCT02621931; FOCUS: NCT02629861.Supplementary InformationThe online version contains supplementary material available at 10.1186/s10194-021-01351-2.

Objective
To evaluate quality of life (QoL) endpoints from two 12-week trials investigating fremanezumab efficacy and safety in Japanese/Korean patients with chronic (CM) or episodic (EM) migraine.Background
Migraine is a leading cause of disability and affects QoL considerably, interfering with work and daily activities, social and family life, and emotional wellbeing.Methods
This planned exploratory analysis used data from two multicenter, randomized, double-blind, placebo-controlled, parallel-group studies in which Migraine-Specific QoL (MSQoL; Role Function-Restrictive [RR], Role Function-Preventive [RP], and Emotional Function [EF] domains) scores and Patient Global Impression of Change (PGIC) scores were pre-specified QoL outcomes in individuals receiving monthly or quarterly fremanezumab or placebo. In both trials, MSQoL was assessed at baseline, and MSQoL and PGIC at Weeks 4, 8, and 12. PGIC responders had a score of ≥5 points, indicating significant improvement.Results
Mean baseline MSQoL scores were similar across groups in both CM (N = 565; RR, 60.3–61.5; RP, 78.5–80.0; EF, 69.0–71.4) and EM (N = 353; RR, 68.6–71.1; RP, 83.1–85.7; EF, 76.7–81.9) trials. In the CM trial, all three MSQoL domains improved in both fremanezumab groups at 12 weeks compared with placebo: least squares mean (LSM) and standard error (SE) change from baseline, p versus placebo (quarterly; monthly; placebo): RR 14.9 (1.3), p = 0.030; 15.1 (1.4), p = 0.020; 11.6 (1.3); RP 8.9 (1.1), p = 0.007; 8.6 (1.1), p = 0.013; 5.4 (1.1); EF 13.3 (1.5), p < 0.001; 12.5 (1.5), p = 0.003; 7.5 (1.5). In the EM trial, RR/EF domains improved in both fremanezumab groups compared with placebo: LSM change from baseline, p versus placebo (quarterly; monthly; placebo): RR 16.3 (1.4), p = 0.003; 16.4 (1.3), p = 0.002; 11.6 (1.4); EF 13.0 (1.3), p < 0.001; 11.5 (1.2), p = 0.004; 7.4 (1.3); RP improved in the quarterly group RP 8.6 (1.1), p = 0.010; 7.6 (1.1), p = 0.066; 5.4 (1.1). The proportion of PGIC responders at Week 12 was greater in the monthly and quarterly fremanezumab groups compared with the placebo group in the CM (96/182 [52.7%] and 98/180 [54.4%] vs. 68/179 [38.0%]; p < 0.05) and EM trial (81/118 [68.6%] and 86/113 [76.1%] vs. 38/111 [34.2%]; p < 0.001).Conclusion
Patients with EM/CM receiving monthly or quarterly fremanezumab, for a duration of 12 weeks, showed significant improvements in their QoL. 相似文献6.

BackgroundGalcanezumab, a humanized monoclonal antibody that binds calcitonin gene-related peptide, has demonstrated efficacy and good tolerability in patients with episodic migraine in previous phase 3 trials. We report results from the PERSIST study, which was designed to assess the efficacy and safety of galcanezumab in patients with episodic migraine from China, India, and Russia.MethodsThis phase 3 study was conducted at 40 centers in China (n = 26), India (n = 10), and Russia (n = 4). Eligible adult patients with episodic migraine were randomized in a 1:1 ratio to receive monthly galcanezumab 120 mg (with 240 mg loading dose) or placebo during a double-blind, 3-month treatment period. The primary endpoint was the overall mean change from baseline in monthly migraine headache days (MHDs). Key secondary endpoints were the mean proportion of patients with ≥ 50%, ≥ 75%, and 100% reductions from baseline in MHDs and mean change in the Migraine-Specific Quality of Life Questionnaire (MSQ) Role Function-Restrictive domain score.ResultsIn total, 520 patients were randomized and received at least one dose of galcanezumab (N = 261) or placebo (N = 259). The least squares (LS) mean reduction from baseline in monthly MHDs over 3 months was significantly greater with galcanezumab compared with placebo (-3.81 days vs. -1.99 days; p < 0.0001). Significantly greater mean proportions of patients with galcanezumab versus placebo had ≥ 50%, ≥ 75%, and 100% reductions from baseline in MHDs (all p < 0.0001). The overall mean improvement from baseline in MSQ Role Function-Restrictive score over 3 months was significantly greater with galcanezumab versus placebo (p < 0.0001). There were no clinically meaningful differences between the galcanezumab and placebo group on any safety parameters except for a higher incidence of injection site pruritus (5.0% vs. 0.0%), injection site reaction (3.8% vs. 0.4%), and injection site discomfort (2.3% vs. 0.0%). TEAEs related to injection sites were mild in severity, except in 1 patient who had a moderate injection site reaction. Six serious adverse events were reported by 6 patients (2 galcanezumab, 4 placebo).ConclusionsGalcanezumab 120 mg once monthly was effective and well tolerated in patients with episodic migraine from China, India, and Russia.Trial registrationClinicalTrials.gov Identifier (PERSIST), registered May 24, 2019.

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 (FOCUS).

BackgroundMigraine 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.MethodsThis 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.ResultsFor 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).ConclusionFremanezumab demonstrated clinically meaningful improvements in disability severity in this pooled analysis.Trial registrationsHALO CM, ; HALO EM, NCT02621931; FOCUS, NCT02629861.

BackgroundIn patients with migraine, overuse of acute medication, including migraine-specific medication (MSM) such as triptans and ergots, can lead to adverse health outcomes, including development of medication overuse headache. Here, we examined the effect of erenumab on reducing acute medication use, in particular MSM, in patients with episodic migraine (EM) and chronic migraine (CM).MethodsThe current post-hoc analyses were based on data from the double-blind treatment phase (DBTP) of two erenumab studies, a pivotal EM (N = 955) and a pivotal CM (N = 667) trial, and their respective extensions. Patients were administered subcutaneous placebo or erenumab (70 or 140 mg) once monthly. Daily acute headache medication use (including MSM and non-MSM) was recorded using an electronic diary during a 4-week pretreatment baseline period until the end of the treatment period. Outcome measures included change in monthly acute headache medication days (HMD) in acute headache medication users at baseline, and changes in monthly MSM days (MSMD) in MSM users at baseline and non-MSMD in non-MSM users at baseline.ResultsIn total, 60 and 78 % of patients (all acute headache medication users) with EM and CM used MSM at baseline, respectively. For acute headache medication users, the change in mean monthly acute HMD over Months 4, 5 and 6 compared with the pre-DBTP was 1.5, 2.5, and 3.0 for placebo, erenumab 70 mg and 140 mg, respectively for the EM study. The respective change in monthly MSMD in MSM users was 0.5, 2.1 and 2.8, and in monthly non-MSMD in non-MSM users was 2.3, 2.6, and 2.7. In the acute headache medication users at baseline, the change in monthly acute HMD at Month 3 compared with pre-DBTP was 3.4, 5.5, and 6.5 for placebo, erenumab 70 mg and 140 mg, respectively for the CM study. The respective change in monthly MSMD in MSM users was 2.1, 4.5, and 5.4, and in monthly non-MSMD in non-MSM users was 5.9, 6.4, and 6.6. Reductions in MSMD versus placebo were sustained in the extension periods of both studies. Erenumab was also associated with a higher proportion of MSM users achieving ≥ 50 %, ≥ 75 and 100 % reduction from baseline in monthly MSMD versus placebo in both EM and CM.ConclusionsIn both EM and CM, treatment with erenumab is associated with a significant and sustained reduction in the use of acute headache medication, in particular MSM.Trial registrations; NCT02456740; NCT02066415.

BackgroundMonoclonal antibodies targeting the calcitonin gene-related peptide (CGRP) pathway, including the fully humanized monoclonal antibody (IgG2Δa) fremanezumab, have demonstrated safety and efficacy for migraine prevention. Clinical trials include responders and nonresponders; efficacy outcomes describe mean values across both groups and thus provide little insight into the clinical benefit in responders. Clinicians and their patients want to understand the extent of clinical improvement in patients who respond. This post hoc analysis of fremanezumab treatment attempts to answer this question: what is the benefit in subjects who responded to treatment during the two, phase 3 HALO clinical trials?MethodsWe included subjects with episodic migraine (EM) or chronic migraine (CM) who received fremanezumab quarterly (675 mg/placebo/placebo) or monthly (EM: 225 mg/225 mg/225 mg; CM: 675 mg/225 mg/225 mg) during the 12-week randomized, double-blind, placebo-controlled HALO EM and HALO CM clinical trials. EM and CM responders were defined as participants with a reduction of ≥ 2 or ≥ 4 monthly migraine days, respectively. Treatment benefits evaluated included reductions in monthly migraine days, acute headache medication use, and headache-related disability, and changes in health-related quality of life (HRQoL).ResultsOverall, 857 participants from the HALO trials were identified as responders (EM: 429 [73.8%]; CM: 428 [56.7%]). Reductions in the monthly average number of migraine days were greater among EM (quarterly: 5.4 days; monthly: 5.5 days) and CM (quarterly: 8.7 days; monthly: 9.1 days) responders compared with the overall population. The proportion of participants achieving ≥ 50% reduction in the average monthly number of migraine days was also greater in responders (EM: quarterly, 59.8%; monthly, 63.7%; CM: quarterly, 52.8%; monthly, 59.0%) than in the overall population. Greater reductions in the average number of days of acute headache medication use, greater reductions in headache-related disability scores, and larger improvements in HRQoL were observed among EM and CM responders compared with the overall populations.ConclusionsFremanezumab responders achieved clinically meaningful improvements in all outcomes. The magnitude of improvements with fremanezumab across efficacy outcomes was far greater in responders than in the overall trial population, providing insight into expected treatment benefits in participants who respond to fremanezumab in clinical practice.Trial registrationClinicalTrials.gov identifiers: (HALO EM) and NCT02629861 (HALO CM).

BackgroundGalcanezumab is a monoclonal antibody (mAb) that binds calcitonin gene-related peptide (CGRP) and is indicated for the preventive treatment of migraine. Galcanezumab demonstrated early onset of effect in patients with migraine but it is unknown whether the same holds true for patients who have not benefited from multiple prior migraine preventives.MethodsPatients with episodic or chronic migraine from a 3-month, randomized, double-blind, placebo-controlled, phase 3b study (CONQUER) who had 2 to 4 migraine preventive medication category failures in the past 10 years were randomized 1:1 to placebo (N = 230) or galcanezumab 120 mg/month (240 mg loading dose; N = 232). In this post-hoc analysis, change from baseline in number of monthly and weekly migraine headache days was assessed. Monthly onset of effect was the earliest month at which significant improvement with galcanezumab compared to placebo was achieved and maintained at all subsequent months. Weekly onset was the initial week at which statistical separation was achieved and maintained at all subsequent weeks during that month. Proportion of patients with migraine headache days in the first week of treatment, and patients achieving ≥50%, ≥75%, and 100% response by month and week were also assessed.ResultsGalcanezumab-treated patients had a significantly greater reduction in monthly migraine headache days starting at month 1, which remained significant for all subsequent months compared to placebo (all p ≤ 0.0001, month 1 mean change from baseline: placebo − 0.7; galcanezumab − 4.0). Weekly migraine headache days was significantly reduced in galcanezumab-treated patients starting at week 1 and continued for each subsequent week of month 1 compared to placebo (all p < 0.01, week 1 mean change from baseline: placebo − 0.2; galcanezumab − 1.1). A significantly smaller percentage of patients had a migraine headache on the first day after galcanezumab treatment compared to placebo (28.4% vs 39.2%) and at each subsequent day during week 1 (all p < 0.05). A greater proportion of galcanezumab-treated patients achieved ≥50%, ≥75%, and 100% response at months 1–3 (all p < 0.05) and at weeks 1–4 of month 1 compared to placebo (all p < 0.01).ConclusionGalcanezumab showed early onset of effect beginning the day after treatment initiation in patients who had not previously benefited from migraine preventive treatments.Trial registrationClinicalTrials.gov, .

BackgroundClinical trials have shown that erenumab is effective and well-tolerated for the preventive treatment of chronic migraine. To extend the results from clinical trials, we assessed the real-world efficacy and safety of erenumab in patients with chronic migraine from the outpatient clinic at the Danish Headache Center.MethodsA 52-week, single-center, prospective, observation study of erenumab in adults with chronic migraine who are eligible for treatment with monoclonal antibodies against CGRP or its receptor in Denmark. The primary outcome was defined as proportion of patients who achieved ≥ 30% reduction in monthly migraine days (MMDs) from baseline to weeks 9–12.ResultsA total of 300 adult patients with chronic migraine were enrolled and received at least one dose of erenumab. At baseline, the mean (SD) number of monthly headache days was 23 ± 4.9 and mean number of MMDs was 16.8 ± 6.4. Of 300 enrolled patients, 273 (91.0%) patients completed 12 weeks of treatment, and 119 (39.7%) completed 52 weeks of treatment. The number of patients who achieved ≥ 30% reduction in MMDs from baseline to weeks 9–12 was 195 (71.4%) of 273 patients. Sustained ≥ 30% reduction in MMDs at all assessment periods throughout the 52-week treatment period was achieved by 102 (34%) of 300 patients. Adverse events occurred in 220 (73.3%) out of 300 patients. The most common adverse event was constipation. Treatment discontinuation due to lack of tolerability occurred in 41 (13.7%) patients.ConclusionsAmong adult patients with chronic migraine and previous failure of medications for migraine prevention, erenumab was found to be effective and well-tolerated. 相似文献

BackgroundThe humanized anti-CGRP monoclonal antibody eptinezumab has been evaluated in five large-scale clinical trials conducted in patients with migraine. This integrated analysis was conducted to evaluate the comprehensive safety and tolerability of eptinezumab in patients with migraine across these studies.MethodsData were pooled from four randomized, double-blind, placebo-controlled studies and the first year of one open-label study.ResultsThe pooled population comprised 2867 adults with migraine: eptinezumab, n = 2076 (4797 infusions); placebo, n = 791 (1675 infusions). A total of 1137/2076 (54.8%) patients who received eptinezumab and 414/791 (52.3%) patients who received placebo experienced ≥1 treatment-emergent adverse event (TEAE); rates were similar across eptinezumab dose groups (10–1000 mg). For most patients with TEAEs, the events were mild or moderate in severity and considered unrelated to study drug by the investigators. Thirty infusion-site AEs occurred in 27/2076 (1.3%) patients who received eptinezumab and 7 in 7/791 (0.9%) patients who received placebo. Infusion-site AEs led to infusion interruption in 19/2076 (0.9%) and 5/791 (0.6%) patients in the eptinezumab and placebo groups, respectively. Nasopharyngitis occurred in ≥2% of patients in the eptinezumab 300-mg group and with an incidence of at least 2 percentage points greater than in the placebo group; however, in most patients (eptinezumab, 139/140; placebo 40/41), its occurrence was considered not related to study treatment. Adverse events coded to hypersensitivity occurred for 23/2076 (1.1%) patients treated with eptinezumab and no patients in the placebo group. If additional TEAE terms that could indicate hypersensitivity are considered (e.g., urticaria, flushing/hot flush, rash, and pruritus), hypersensitivity reactions in the two pivotal placebo-controlled phase 3 studies occurred in ≥2% of patients in the eptinezumab 100-mg and 300-mg groups, and the incidence was at least 2 percentage points greater in either of these groups than in the placebo group. Most hypersensitivity reactions were not serious and resolved with standard medical treatment or observation without treatment, usually within 1 day.ConclusionsIn adults with migraine, the intravenous administration of eptinezumab every 12 weeks demonstrated a favorable safety and tolerability profile.Trial registrationClinicalTrials.gov (Identifiers: , NCT01772524, NCT02275117, NCT02559895, NCT02974153).Supplementary InformationThe online version contains supplementary material available at 10.1186/s10194-021-01227-5.

Background
Subcutaneous erenumab reduced monthly migraine days and increased the likelihood of achieving a?≥?50% reduction at all monthly assessment points tested in 2 pivotal trials in episodic migraine (EM) and chronic migraine (CM). Early efficacy of migraine preventive medications is an important treatment characteristic to patients. Delays in achievement of efficacy can result in failed adherence. The objective of these post-hoc analyses were to evaluate efficacy in the first 4 weeks after initial subcutaneous administration of erenumab 70 mg, erenumab 140 mg, or placebo.Methods
There is no generally accepted methodology to measure onset of action for migraine preventive medications. We used a comprehensive approach with data from both studies to evaluate change from baseline in weekly migraine days (WMD), achievement of ≥?50% reduction in WMD, and proportion of patients experiencing migraine measured on a daily basis. The 7-day moving averages were overlaid with observed data.Results
In both studies (EM: N?=?955; CM: N?=?667), there was evidence of onset of efficacy of erenumab vs. placebo during the first week of treatment, which in some cases reached nominal significance. For EM the changes in WMD were (least squares mean [LSM] [95% CI]): placebo, ??0.1 (??0.3, 0.0); erenumab 70 mg, ??0.3 (??0.5, ??0.2) p?=?0.130; erenumab 140 mg, ??0.6 (??0.7, ??0.4) p?<?0.001. For CM the changes were: placebo, ??0.5 (??0.8, ??0.3); erenumab 70 mg, ??0.9 (??1.2, ??0.7) p?=?0.047; erenumab 140 mg, ??0.8 (??1.1, ??0.5) p?=?0.18. Achievement of ≥?50% reduction in WMD was observed as early as Week 1 (adjusted OR [95% CI] erenumab vs placebo) in EM: erenumab 70 mg, 1.3 (1.0, 1.9) p?=?0.097; erenumab 140 mg, 2.0 (1.4, 2.7) p?<?0.001. A similar outcome was observed for CM: erenumab 70 mg, 1.8 (1.1, 2.8) p?=?0.011; erenumab 140 mg, 1.9 (1.2, 2.9) p?=?0.009. Seven-day moving averages of observed data showed each treatment arm differed from placebo by Week 1 (OR [95% CI]): in EM Day 3 for erenumab 140 mg, 0.7 (0.5, 1.0) p?=?0.031 and at Day 7 for 70 mg, 0.6 (0.4, 0.8) p?=?0.002; in CM: Day 6 for erenumab 70 mg, 0.6 (0.4, 0.9) p?=?0.022 and at Day 7 for 140 mg, 0.7 (0.4, 1.0); p?=?0.038.Conclusion
Erenumab showed early onset of efficacy with separation from placebo within the first week of treatment in both chronic and episodic migraine patients.20.

BackgroundMigraine is a primary headache disorder that can be classified into an episodic (EM) and a chronic form (CM). Network analysis within the graph-theoretical framework based on connectivity patterns provides an approach to observe large-scale structural integrity. We test the hypothesis that migraineurs are characterized by a segregated network.Methods19 healthy controls (HC), 17 EM patients and 12 CM patients were included. Cortical thickness and subcortical volumes were computed, and topology was analyzed using a graph theory analytical framework and network-based statistics. We further used support vector machines regression (SVR) to identify whether these network measures were able to predict clinical parameters.ResultsNetwork based statistics revealed significantly lower interregional connectivity strength between anatomical compartments including the fronto-temporal, parietal and visual areas in EM and CM when compared to HC. Higher assortativity was seen in both patients’ group, with higher modularity for CM and higher transitivity for EM compared to HC. For subcortical networks, higher assortativity and transitivity were observed for both patients’ group with higher modularity for CM. SVR revealed that network measures could robustly predict clinical parameters for migraineurs.ConclusionWe found global network disruption for EM and CM indicated by highly segregated network in migraine patients compared to HC. Higher modularity but lower clustering coefficient in CM is suggestive of more segregation in this group compared to EM. The presence of a segregated network could be a sign of maladaptive reorganization of headache related brain circuits, leading to migraine attacks or secondary alterations to pain.Supplementary InformationThe online version contains supplementary material available at 10.1186/s10194-021-01216-8. 相似文献
