Key clinical point: Obefazimod (ABX464) at a dose of 50 mg showed promising efficacy and was safe and well-tolerated in patients with moderate-to-severely active rheumatoid arthritis (RA).

Major finding: A dose of 50 mg ABX464 vs. placebo was associated with numerically more severe adverse events (14.3% vs. 5%) but with no malignancies, opportunistic infections, or deaths, and a significant reduction in the Disease Activity Score 28-C reactive protein (−1.41 vs. −0.60; P = .043) and Clinical Disease Activity Index Score (−15.8 vs. −6.9; P = .020) at week 12.

Study details: This was a phase 2 trial including 60 patients with moderate-to-severely active RA and inadequate response to methotrexate or anti-tumor necrosis factor alpha therapy who were randomly assigned to ABX464 or placebo in combination with methotrexate for 12 weeks.

Disclosures: The study was supported by Abivax. C Daien reported receiving consulting fees, punctual links, or research grants from Abivax and other sources. Ten authors reported being current/former employees or investigators contracted by Abivax.

Key clinical point: Severe migraine without aura increased the long-term risk for atrial fibrillation (AF) by 16%-21% in both men and women. The risk for future AF was highest in women with severe migraine with aura but not significant in male counterparts.

Major finding: Men (adjusted hazard ratio [aHR] 1.21; 95% CI 1.12-1.31) and women (aHR 1.16; 95% CI 1.09-1.22) with severe migraine without aura had a modest but significantly higher risk for AF. The risk was most prominent in women with severe migraine with aura (aHR 1.48; 95% CI 1.18-1.85), but was not significant in men.

Study details: Findings are from a large-scale population-based study including 4,020,488 participants without AF, of which 4986 and 105,029 had migraine with and without aura, respectively.

Disclosures: This study was supported by a Korea Medical Device Development Fund grant funded by the Korea Government. E-K Choi and GYH Lip reported receiving research grants or speaking fees or serving as consultants or speakers for various sources.

Key clinical point: A higher proportion of patients with migraine treated with atogepant vs. placebo showed a significant reduction in the monthly migraine days (MMD) during the 12 weeks of treatment.

Major finding: At 12 weeks, ≥50% reduction in the mean MMD was achieved by a significantly higher proportion of patients receiving 10 mg (55.6%), 30 mg (58.7%), or 60 mg (60.8%) atogepant compared with placebo (29.0%; all P < .001), with findings being similar for ≥25%, ≥75%, and 100% reduction in mean MMD. The incidence of treatment-emergent adverse events was similar among the treatment groups.

Study details: This was a secondary analysis of the ADVANCE trial including 873 patients with a ≥1-year history of migraine with or without aura who were randomly assigned to receive atogepant (10, 30, or 60 mg; n = 659) or placebo (n = 214).

The other factors independently associated with migraine were hypertension (aOR 1.97; P = .011), female gender (aOR 2.03; P = .017) and National Institutes of Health Stroke Scale score at admission (aOR 1.08; P = .018).

Study details: This cross-sectional study included 750 patients aged ≥18 years with ischemic stroke, of which 11.3% had migraine history.

Key clinical point: Erenumab is effective and well tolerated in patients with chronic migraine who did not respond to previous migraine treatments.

Major finding: Overall, 71.4% of patients treated with erenumab achieved ≥30% reduction in monthly migraine days from baseline to 9-12 weeks and 34.0% of patients at all assessment periods through 52 weeks. Constipation was the most common adverse event and 13.7% of patients discontinued treatment because of a lack of tolerability.

Study details: The data come from a 52-week, prospective, observational study including 300 patients with chronic migraine who received ≥1 dose of erenumab, of which 273 and 119 patients completed 12 and 52 weeks of treatment, respectively.

Key clinical point: Intravenous (IV) ketorolac plus metoclopramide failed to improve pain intensity in children presenting to the emergency department (ED) for the acute treatment of migraine compared with metoclopramide monotherapy.

Major finding: The mean change in pain intensity as assessed by a 100 mm Visual Analog Scale at 120 minutes was −44 mm (95% CI 32-57 mm) in the monotherapy group and −36 mm (95% CI 23-49 mm) in the ketorolac group, corresponding to a mean difference of 8 mm between the groups (P = .355), with no significant between-group difference in headache recurrence and adverse events.

Study details: Findings are from a double-blind, randomized placebo-controlled trial including 53 children aged 6-17 years presenting to the ED for the acute treatment of migraine. They were randomly assigned to receive IV ketorolac plus metoclopramide (n = 26) or IV metoclopramide plus placebo (n = 27).

Key clinical point: Patients hospitalized with refractory chronic migraine treated with continuous multiday lidocaine infusions showed a significant improvement in pain immediately after the infusion, with some patients maintaining this improvement at 1 month.

Major finding: Median pain ratings decreased from 7.0 on admission to 1.0 at discharge (P < .001), with 87.8% of admissions being cases of acute response. Among acute responders with data on average pain, 43.2% demonstrated sustained response at 1 month.

Study details: The data come from a retrospective cohort study of 609 hospital admissions involving 537 patients with refractory chronic migraine who received continuous multiday lidocaine infusions.

Key clinical point: Cold interventions, including cold-gel headband, cold-gel cap, and intraoral cooling, provide instant relief from pain in patients with migraine; however, their long-term effects on pain are not significant.

Major finding: The cold intervention group vs. control group led to a significant reduction in pain on a visual analog scale score at 30 minutes (standard mean difference [SMD] −3.21; P = .02) but a nonsignificant reduction in the score at 24 hours (SMD −0.44; P = .07) after the intervention.

Study details: This was a meta-analysis of 6 studies (4 randomized controlled trials and 2 quasi-experimental studies) that included adult patients with migraine who underwent a cold intervention.

Disclosures: The study was partially sponsored by the Ministry of Science and Technology, Israel. The authors declared no conflicts of interest.

Key clinical point: As a migraine preventive agent, fremanezumab is effective across the full patient spectrum, including those with episodic migraine (EM), chronic migraine (CM), and difficult-to-treat (DTT) migraine (patients with medication overuse [MO], major depressive disorder [MDD], generalized anxiety disorder [GAD], or exposure to a different calcitonin gene-related peptide monoclonal antibody [CGRP mAb]).

Major finding: At month 6, the mean monthly migraine days reduced in patients with EM (−7.7 days), CM (−10.1 days), MO (−10.8 days), MDD (−9.9 days), GAD (−9.5 days), and prior CGRP mAb exposure (−9.0 days).

Study details: Findings are from a retrospective, online chart review study that collected data from 1003 patients with EM/CM aged ≥18 years at fremanezumab initiation, including those with DTT migraine, and 421 clinicians treating patients with EM/CM in a US-based practice.

Disclosures: This study was funded by Teva Pharmaceuticals. All authors declared being current or former employees of Teva Pharmaceuticals or Analysis Group, which performed these analyses funded by Teva.
