- Early use of erenumab vs nonspecific oral migraine preventives: the APPRAISE randomized clinical trialPublication . Pozo-Rosich, Patricia; Dolezil, David; Paemeleire, Koen; Stepien, Adam; Stude, Philipp; Snellman, Josefin; Arkuszewski, Michal; Stites, Tracy; Ritter, Shannon; Lopez, Cristina Lopez; Maca, Jeff; Ferraris, Matias; Gil-Gouveia, RaquelImportance: Patients with migraine often cycle through multiple nonspecific preventive medications due to poor tolerability and/or inadequate efficacy leading to low adherence and increased disease burden. Objective: To compare the efficacy, tolerability, patient adherence, and patient satisfaction between erenumab and nonspecific oral migraine preventive medications (OMPMs) in patients with episodic migraine (EM) who had previously failed 1 or 2 preventive treatments. Design, Setting, and Participants: The 12-month prospective, interventional, global, multicenter, active-controlled, randomized clinical trial comparing sustained benefit of 2 treatment paradigms (erenumab qm vs oral prophylactics) in adult episodic migraine patients (APPRAISE) trial was a 12-month open-label, multicenter, active-controlled, phase 4 randomized clinical trial conducted from May 15, 2019, to October 1, 2021. This pragmatic trial was conducted at 84 centers across 17 countries. Overall, participants 18 years or older with a 12-month or longer history of migraine, and 4 or more but fewer than 15 monthly migraine days (MMDs) were included. Interventions: Patients were randomized (2:1) to receive erenumab or OMPMs. Dose adjustment was permitted (label dependent). Main Outcomes and Measures: The primary end point was the proportion of patients completing 1 year of the initially assigned treatment and achieving a reduction of 50% or greater from baseline in MMDs at month 12. Secondary end points included the cumulative mean change from baseline in MMDs during the treatment period and the proportion of responders according to the Patients' Global Impression of Change (PGIC) scale at month 12 for patients taking the initially assigned treatment. Results: A total of 866 patients were screened, of whom 245 failed the screening and 621 completed the screening and baseline period. Of the 621 randomized patients (mean [SD] age, 41.3 [11.2] years; 545 female [87.8%]; 413 [66.5%] in the erenumab group; 208 [33.5%] in the OMPM group), 523 (84.2%) completed the treatment phase, and 98 (15.8%) discontinued the study. At month 12, significantly more patients assigned to erenumab vs OMPM achieved the primary end point (232 of 413 [56.2%] vs 35 of 208 [16.8%]; odds ratio [OR], 6.48; 95% CI, 4.28-9.82; P <.001). Compared with OMPMs, treatment with erenumab showed higher responder rate (314 of 413 [76.0%] vs 39 of 208 [18.8%]; OR, 13.75; 95% CI, 9.08-20.83; P <.001) on the PGIC scale (≥5 at month 12). Significant reduction in cumulative average MMDs was reported with erenumab treatment vs OMPM treatment (-4.32 vs -2.65; treatment difference [SE]: -1.67 [0.35] days; P <.001). Substantially fewer patients in the erenumab arm compared with the OMPM arm switched medication (9 of 413 [2.2%] vs 72 of 208 [34.6%]) and discontinued treatment due to adverse events (12 of 408 [2.9%] vs 48 of 206 [23.3%]). No new safety signals were identified. Conclusions and Relevance: Results of this randomized clinical trial demonstrated that earlier use of erenumab in patients with EM who failed 1 or 2 previous preventive treatments provided greater and sustained efficacy, safety, and adherence than continuous OMPM.

- Efficacy and safety of erenumab for nonopioid medication overuse headache in chronic migraine a phase 4, randomized, placebo-controlled trialPublication . Tepper, Stewart J.; Dodick, David W.; Lanteri-Minet, Michel; Dolezil, David; Gil-Gouveia, Raquel; Lucas, Christian; Piasecka-Stryczynska, Karolina; Szabo, Gyoengyi; Mikol, Daniel D.; Chehrenama, Mahan; Chou, Denise E.; Yang, Yiping; Lima, Gabriel Paiva da SilvaIMPORTANCE Patients with chronic migraine and medication overuse headaches (CM-MOH) represent a particularly burdened subpopulation. This trial provides first, to our knowledge, American Academy of Neurology class I evidence for a preventive therapy in CM-MOH. OBJECTIVE To assess erenumab efficacy and safety in patients with nonopioid CM-MOH. DESIGN, SETTINGS, AND PARTICIPANTS This randomized, double-blind, parallel-group, placebo-controlled trial took place at 67 centers in North America, Europe, and Australia from October 7, 2019, to November 2, 2022. This report reflects the primary analysis conducted in January 2023, using a database snapshot from December 1, 2022, which contains the complete dataset of the double-blind treatment period (DBTP). Participants included adults with CM-MOH who had 1 or more preventive treatment failure(s). There were 992 participants screened and 620 participants enrolled (584 in nonopioid cohort and 36 in opioid cohort) INTERVENTIONS Erenumab, 70 mg, 140 mg, or placebo, once monthly for 24 weeks. MAIN OUTCOMES AND MEASURES The primary end point was MOH remission at month 6. Secondary end points included change from baseline in mean monthly acute headache medication days (AHMD) at month 6 and sustained MOH remission throughout the DBTP. Safety end points were adverse events and changes in vital signs. RESULTS The primary analysis population included 584 participants in the nonopioid-treated cohort with a mean age of 44 years and 482 participants were female (82.5%). Baseline demographics and disease characteristics were balanced across groups. At month 6, 134 participants in the erenumab, 140 mg group (69.1%) (odds ratio [OR], 2.01; 95% CI, 1.33-3.05; P < .001 vs placebo) and 117 in the erenumab, 70 mg group (60.3%) (OR, 1.37; 95% CI, 0.92-2.05; P = .13 vs placebo) achieved MOH remission vs 102 participants in the placebo group (52.6%). AHMD use was also reduced in the erenumab groups vs placebo. Least squares mean (standard error) change from baseline in average monthly AHMD was –9.4 (0.4) days in the erenumab, 140 mg group (difference from placebo, –2.7; 95% CI, –3.9 to –1.6; P < .001) and –7.8 (0.4) days in the erenumab, 70 mg group (difference from placebo, –1.2; 95% CI, –2.4 to –0.1; P = .03), vs –6.6 (0.4) days in the placebo group. MOH remission throughout the DBTP was sustained in 119 participants (61.3%,) 96 participants (49.5%), and 73 participants (37.6%) in the erenumab, 140 mg, 70 mg, and placebo groups, respectively. Adverse events were consistent with the known safety profile of erenumab. Treatment-emergent adverse events incidence in the combined erenumab group was 66.8% (259 participants; constipation 15.2% (59 participants) and COVID-19 13.9% (54 participants) were most common. CONCLUSIONS AND RELEVANCE In this study, monthly, 140 mg, erenumab injections safely and effectively achieved MOH remission in patients with nonopioid CM-MOH within 6 months.
- Efficacy and safety of erenumab in adults with medication overuse headache: final results from a phase 4 randomized placebo-controlled studyPublication . Tepper, Stewart J.; Dodick, David W.; Lanteri-Minet, Michel; Dolezil, David; Gil-Gouveia, Raquel; Lucas, Christian; Piasecka-Stryczynska, Karolina; Szabó, Gyöngyi; Mikol, Daniel D.; Chehrenama, Mahan; Chou, Denise E.; Liu, Zilu; Lima, Gabriel Paiva da SilvaBackground: Erenumab-induced medication overuse headache (MOH) remission in participants with chronic migraine (CM) in a prospective, Phase 4, randomized, placebo-controlled trial with an open-label treatment period (OLTP). We present 1-year results from the combined double-blind treatment period (DBTP) and OLTP for the stratified nonopioid cohort. Methods: Participants with CM-MOH were randomized 1:1:1 to subcutaneous 70 or 140 mg erenumab every 4 weeks (QM) or placebo for the initial 24 weeks (DBTP). Those successfully completing DBTP could continue the 28-week OLTP, maintaining the same erenumab dose received during DBTP or, if receiving placebo, randomly assigned 1:1 to erenumab 70 or 140 mg QM. OLTP endpoints were exploratory. Results: Overall, 552 participants received erenumab (70 mg, n = 274; 140 mg, n = 278); 95.3% completed OLTP. One-year MOH relapse in participants who achieved MOH remission at DBTP Month 6 was 2.7% (3/111) and 2.4% (3/124) with erenumab 70 and 140 mg, respectively; absence of MOH at study end was observed in 69.0% (189/274) and 75.5% (210/278) of participants. Sustained MOH absence over 1 year was reported in 60.5% (107/177) and 68.8% (119/173) of participants, respectively. Sustained improvements in measures of headache days, medication days, and function were observed in both groups. No new safety concerns were identified (grade ? 3, 35 [6.3%]; serious, 17 [3.1%]; adverse events leading to treatment discontinuation, 5 [0.9%]). Conclusions: Erenumab was effective in inducing and sustaining MOH remission and improving function over 1 year. Treatment compliance remained high, with safety events consistent with erenumab's known safety profile. Trial Registration: NCT03971071.
