Comparative Efficacy and Safety of Calcitonin Gene-Related Peptide Monoclonal Antibodies Versus Oral Gepants for Episodic Migraine Prevention: A Bayesian Network Meta-Analysis of Randomized Controlled Trials
Abstract
Background: : Calcitonin gene-related peptide (CGRP)-targeted therapies, including injectable monoclonal antibodies (mAbs: erenumab, fremanezumab, galcanezumab, eptinezumab) and oral gepants (atogepant, rimegepant), represent a paradigm shift in episodic migraine prevention. No direct head-to-head trials across the full drug class exist. We conducted a PRISMA-NMA-compliant Bayesian network meta-analysis (NMA) to compare the relative efficacy and tolerability of all approved CGRP-targeted preventive therapies. Methods. PubMed, Embase, and Cochrane CENTRAL (inception to January 2026) were searched for doubleblind RCTs in episodic migraine. A Bayesian random-effects NMA used Markov Chain Monte Carlo simulation. Primary outcome: change in monthly migraine days (MMD). Secondary outcomes: 50% or greater responder rate, TEAEs, and DAEs. SUCRA probabilities quantified treatment rankings. Transitivity was formally assessed. Publication bias was evaluated using comparison-adjusted funnel plots and Egger test. GRADE certainty was rated for all key comparisons. Results. Thirty-two RCTs (24,418 participants; mean age 39.2 years; 84% female; mean baseline 8.2 MMD) were included (Table 1). All active treatments significantly reduced MMD versus placebo. Eptinezumab 300 mg ranked highest for MMD reduction (MD 2.40 MMD, 95% CrI 3.10 to 1.70; SUCRA 91.2%), followed by galcanezumab 240 mg (SUCRA 85.4%) and erenumab 140 mg (SUCRA 79.8%). For the 50% responder rate, galcanezumab 240 mg ranked…
