Therefore, we attempted to calculate the pooled placebo response with subcutaneous placebo injections in this systematic review and meta-analysis. Methods: We identified 16 randomized controlled trials that met our inclusion and exclusion criteria through a comprehensive search in five electronic databases (PubMed Central, EMBASE, MEDLINE, Cochrane library and clinicaltrials.gov). The risk of bias was assessed for all included studies. Random effects model was used to calculate pooled mean monthly migraine days and 50% response rates. Results: A total of 4240 subjects were included from 16 studies in this meta-analysis. The pooled mean monthly migraine day reduction with subcutaneous placebo injections was 2.15 (95% CI: 1.60–2.69). The pooled proportion of patients achieving a 50% reduction in mean monthly headache days was 26% (95% CI: 20%–31%). Placebo response accounted for more than 50% of therapeutic gain in our study. Conclusion: A substantial placebo response was noted with subcutaneous injections in migraine CGRP monoclonal antibody clinical trials.

It is not yet fully understood what predicts treatment response. Objective: To identify factors associated with good or poor response to erenumab, the first available CGRP monoclonal antibody. Methods: A chart review of patients with migraine from a large headache center who received at least three 4-weekly doses of erenumab between 2018 and 2020 was conducted. Clinical variables were compared between erenumab responders (defined as ≥30% reduction in monthly headache or migraine days at 3 months) and non-responders via logistic regression analyses. Results: Among 90 enrolled patients, 62.2% were erenumab responders and 37.8% non-responders. A significantly larger proportion of non-responders were unemployed (58.8% vs. 28.6%), had complex diagnosis (chronic migraine overlapping another primary or secondary headache) (47.1% vs. 14.3%), higher monthly headache days (30 vs. 25.5) and migraine days (20 vs. 12), a higher frequency of daily headache (76.5% vs. 48.2%), and failed more preventive therapies (5.5 vs. 3). Based on logistic regressions, erenumab responsiveness did not significantly associate with duration of migraine, presence of aura, medication overuse, number of concurrent preventives, response to onabotulinumtoxinA or triptans, or certain comorbidities and substance use. Conclusions: This work may help improve selection of patients who may benefit from erenumab, but further prospective research studies are needed.","PeriodicalId":9702,"journal":{"name":"Cephalalgia Reports","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45485119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This retrospective observational study sought to describe early real-world use of erenumab. Methods: This study used the Practice Fusion ambulatory Electronic Health Record database, which represents approximately 6% of ambulatory care among primary care and specialist practices in the United States. Among migraine patients initiating erenumab, demographics, migraine type, comorbidities, and prior treatments were assessed during the 12-month baseline period. Treatment patterns including changes in acute and preventive medications, switches to other CGRP mAbs (fremanezumab and galcanezumab), and for erenumab, changes in dose and adherence were examined among patients with 6 months of follow-up. Results: Of 3,336 patients identified (85.9% female; mean age = 49.1 years), approximately 40% had documentation of chronic migraine. Common comorbidities included non-migraine headache, anxiety, depression, and hypertension. Most patients (76.3%) initiated on the 70 mg dose of erenumab. Among 1,638 patients included in the treatment pattern analysis, 53.1% used acute medications and 55.7% used other non-specific preventive migraine medications during follow-up, reductions of 9.8% and 10.2%, respectively, over the same period of time before index. Switching to fremanezumab and galcanezumab were observed in 12.2% and 13.8% of patients, respectively. The mean proportion of days covered by erenumab at 6 months was 79%. Dosage of erenumab increased (from 70 mg to 140 mg) in 13.0% and decreased (from 140 mg to 70 mg) in 24.9% of patients.

Citizen science project data collection opens the possibility to examine these differences based on a large number of individual attacks instead of a simple survey of patients. Methods: One thousand three hundred and ninety four participants reported 47,274 migraine attacks via an online platform and smartphone apps. The reports contained information on the acute medications taken, the evaluation of their effect, and information on pain parameters such as pain intensity, origin, and localization. Chi-square tests were used to investigate whether the effect of acute medications and pain parameters differed when collated by gender and migraine type (migraine with and without aura). Results: Our participants rated the effectiveness of triptans as significantly better than that of ibuprofen. For triptans, significant differences in effectiveness were found when migraine types were distinguished, but no difference was found between genders. For ibuprofen, there were no differences between migraine types but significant differences between gender groups. Examination of pain parameters reveals differences between groups in pain intensity, pain origin, and pain location. The differences are statistically significant, but the effects are small. Conclusions: Despite some methodological limitations, web-based data collection is able to support findings from clinical trials in a real-world setting. Due to the high numbers of participants included and attacks reported, even small differences in medication efficacy and pain parameters between the groups considered can be demonstrated to be statistically significant.","PeriodicalId":9702,"journal":{"name":"Cephalalgia Reports","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41679184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results: Following PS matching, both cohorts included 2,343 patients. At 6 months, erenumab was associated with significantly less acute medication usage versus OMPM, including number of types of acute medications used, number of claims per person, and proportion of patients using acute medication.
