Efficacy and safety of eptinezumab 300mg versus 100mg for migraine patients: a meta-analysis of randomized controlled studies

Introduction: Eptinezumab holds important promise in treating migraine patients, but its ideal dose is unknown. This meta-analysis aims to compare the efficacy and safety of eptinezumab 300 mg versus 100 mg for migraine patients.Methods: Several databases including PubMed, Web of science, EBSCO, EMbase and Cochrane library databases have been systematically searched and we included the randomized controlled trials (RCTs) assessing the effect of eptinezumab 300 mg versus 100 mg for migraine patients. This meta-analysis was conducted using the random-effect model.Results: Five RCTs and 1989 patients were included in the meta-analysis. Compared with eptinezumab 100 mg in migraine patients, eptinezumab 300 mg was associated with substantially reduced monthly migraine days (MD=-0.50; 95% CI=-0.56 to -0.44; p < 0.00001), increased 75% responder rate (OR = 1.32; 95% CI = 1.07 to 1.62; p = 0.008) and 50% responder rate (OR = 1.24; 95% CI = 1.04 to 1.48; p = 0.02), but unraveled no remarkable influence on migraine 1 day after dosing (OR = 0.92; 95% CI = 0.72 to 1.18; p = 0.52), adverse events (OR = 1.07; 95% CI = 0.81 to 1.42; p = 0.62) or serious adverse events (OR = 1.60; 95% CI = 0.68 to 3.74; p = 0.40).Conclusions: Eptinezumab 300 mg was superior to eptinezumab 100 mg for the treatment of migraine patients.

Eptinezumab for the preventive treatment of episodic and chronic migraine: a narrative review

Eptinezumab, a monoclonal antibody that targets calcitonin gene-related peptide (CGRP), was recently approved in Europe for the prophylactic treatment of migraine in adults who have at least four migraine days a month. Eptinezumab is administered by intravenous infusion every 12 weeks. During recent months, a considerable amount of evidence from eptinezumab trials has been published. The aim of this review is to describe the existing evidence on the tolerability, safety and efficacy of eptinezumab in patients with migraine. Data from randomized (PROMISE-1, PROMISE-2, RELIEF and DELIVER) and open-label (PREVAIL) phase 3 clinical trials have demonstrated the favorable effect of eptinezumab in migraine symptoms from first day of treatment. These studies showed that eptinezumab results in an overall reduction in mean monthly migraine days (MMDs), increases in the ≥50% and ≥ 75% migraine responder rates (MRRs) and improvements in patient-reported outcome measures in both patients with episodic migraine (EM) and with chronic migraine (CM), including patients who failed previous preventive treatments. The RELIEF trial also showed that eptinezumab, within 2 h of administration, reduced headache pain, migraine-associated symptoms and acute medication use when administered during a migraine attack. Eptinezumab benefits manifested as early as day 1 after dosing and with the subsequent doses lasted up to at least 2 years. Treatment-emergent adverse events reported by ≥2% of patients included upper respiratory tract infection and fatigue. Current evidence demonstrates that eptinezumab has a potent, fast-acting, sustained migraine preventive effect in patients with EM and CM. Eptinezumab has also shown to be well tolerated, supporting its use in the treatment of patients with migraine and inclusion in the current migraine therapeutic options.

Eptinezumab improved patient-reported outcomes and quality of life in patients with migraine and prior preventive treatment failures

BACKGROUND AND PURPOSE

In the phase 3b, randomized, double-blind, placebo-controlled DELIVER clinical trial, eptinezumab reduced migraine frequency and headache in adults with two to four prior preventive treatment failures. Here, the effect of eptinezumab on coinciding patient-reported outcomes is reported.

METHODS

Adults were randomized to receive eptinezumab 100, 300 mg or placebo intravenously at weeks 12 and 24. The EQ-5D-5L, measuring overall patient health, and the six-item Headache Impact Test were completed every 4 weeks. The Patient Global Impression of Change was completed at weeks 4, 12 and 24. Patient-identified most bothersome symptom and the Migraine-Specific Quality of Life Questionnaire were administered at weeks 12 and 24.

RESULTS

Eptinezumab improved patient-reported outcomes more than placebo, starting at week 4 and at all subsequent time points. By week 12, patients' overall health (EQ-5D-5L visual analog scale score) improved with eptinezumab treatment (difference from placebo in change from baseline: 100 mg, 5.1, 95% confidence interval [CI] 2.2, 8.1, p < 0.001; 300 mg, 7.5, 95% CI 4.5, 10.4, p < 0.0001). At week 12, eptinezumab improved headache-related quality of life (difference from placebo in change from baseline in Headache Impact Test total score: 100 mg, -3.8, 95% CI -5.0, -2.5, p < 0.0001; 300 mg, -5.4, 95% CI -6.7, -4.2, p < 0.0001), including each Migraine-Specific Quality of Life Questionnaire domain (p ≤ 0.0001, all comparisons). Over twice as many patients receiving eptinezumab than placebo reported much or very much improvement on the Patient Global Impression of Change and patient-identified most bothersome symptom.

CONCLUSION

Patients with two to four prior preventive treatment failures receiving eptinezumab versus placebo reported greater improvements in well-being, quality of life and most bothersome symptoms compared to placebo.

Monoclonal Antibodies against Calcitonin Gene-Related Peptide for Migraine Prophylaxis: A Systematic Review of Real-World Data

OBJECTIVE

To perform a systematic review of real-world outcomes for anti-CGRP-mAbs.

METHODS

Following the PRISMA guidelines, we searched PubMed for real-world data of erenumab, galcanezumab, fremanezumab, or eptinezumab in patients with migraines.

RESULTS

We identified 134 publications (89 retrospective), comprising 10 pharmaco-epidemiologic and 83 clinic-based studies, 38 case reports, and 3 other articles. None of the clinic-based studies provided follow-up data over more than one year in more than 200 patients. Findings suggest that there are reductions in health insurance claims and days with sick-leave as well as better treatment adherence with anti-CGRP-mAbs. Effectiveness, reported in 77 clinic-based studies, was comparable to randomized controlled trials. A treatment pause was associated with an increase in migraine frequency, and switching to another antibody resulted in a better response in some of the patients. Adverse events and safety issues were addressed in 86 papers, including 24 single case reports.

CONCLUSION

Real-world data on anti-CGRP-mAbs are limited by retrospective data collection, small patient numbers, and short follow-up periods. The majority of papers seem to support good effectiveness and tolerability of anti-CGRP-mAbs in the real-world setting. There is an unmet need for large prospective real-world studies providing long-term follow-ups of patients treated with anti-CGRP-mAbs.
