Lundbeck presents new data at AAN 2026 highlighting real-world changes in migraine-related cognitive symptoms after starting VYEPTI® (eptinezumab)

• The one-year INFUSE study observed patient-reported migraine-related cognitive symptoms at baseline and changes over 6 months in those with at least one prior anti-calcitonin gene-related peptide (anti-CGRP) treatment failure

VALBY, Denmark, April 19, 2026 /PRNewswire/ — H. Lundbeck A/S (Lundbeck) today presented new real-world 6-month results from the INFUSE study at the American Academy of Neurology (AAN) 2026 Annual Meeting, underscoring the importance of evaluating the broad burden of migraine beyond headache and migraine frequency. Despite being among the most frequently reported symptoms by people living with migraine, cognition and brain fog have rarely been systematically studied. These patient-reported outcomes data highlight the opportunity to focus on elements of migraine burden that are meaningful to individuals living with migraine and report improvement of migraine-related cognitive symptoms after eptinezumab treatment.[1]

«Migraine is a highly individualized neurological disease characterized by fluctuating symptoms, disability, and quality-of-life impairment. My patients often describe ‘brain fog’ associated with migraine as profoundly disruptive, hindering their ability to perform at work, engage with family, or simply enjoy daily life,» said INFUSE study author Dr. Amaal Starling, Neurologist, Mayo Clinic. «The INFUSE study findings are meaningful as patients report improvements in cognitive symptoms associated with migraine after starting eptinezumab. These data further support more comprehensive goals with patients who have high disease burden despite prior anti-CGRP preventive treatment to better address their needs and improve outcomes.»

Data from the 6-month interim analysis of the INFUSE study underscored the importance of real-world evidence to inform clinical practice with the aim to address the holistic burden of migraine with preventive treatments. This specific analysis focused on cognitive improvements. The study demonstrated that migraine-related cognitive symptoms are highly prevalent and bothersome among patients at baseline. Specific symptoms that were considered moderately to extremely bothersome, like difficulty making decisions, difficulty with reading comprehension, difficulty with complex tasks, and brain fog (difficulty concentrating/focusing, trouble finding right words/speaking, mental cloudiness) were reported by 64.7%, 60.0%, 62.6%, and 82.1% of participants, respectively. This population, characterized by a high disease impact, reported improvements following treatment with eptinezumab. Across individual cognitive symptoms (brain fog, difficulty making decisions, difficulty with reading comprehension and difficulty with complex tasks), more than 50% of participants reported improvements at 6 months (after 2 doses of eptinezumab) compared to baseline, with marked improvements observed as early as Day 7 post-treatment.[1]

«These real-world, patient-reported INFUSE data give greater insight into the management of the holistic burden of migraine – including highly prevalent cognitive symptoms – to better support optimal treatment decisions,» said Damian Fiore, Vice President, Lundbeck US Medical Affairs Neurology. «We’re excited to share new data that may help redefine expectations for preventive migraine treatment and reinforce our commitment to raising the standard of migraine care.»

About VYEPTI

VYEPTI® (eptinezumab) is a humanized monoclonal antibody that binds to calcitonin gene-related peptide (CGRP) ligand and blocks its binding to the receptor. eptinezumab was deliberately developed for administration by intravenous (IV) infusion to deliver 100 percent of the medication into the bloodstream at the end of the infusion.

The efficacy and safety of eptinezumab were demonstrated in two phase 3 clinical trials; episodic migraine in PROMISE-1 and chronic migraine in PROMISE-2. Eptinezumab met its primary endpoint of decrease in mean monthly migraine days (MMD) over months 1-3 in both episodic and chronic migraine. The safety of eptinezumab was evaluated in 2,076 patients with migraine who received at least one dose of eptinezumab. The most common adverse reactions (≥2 percent and at least 2 percent or greater than placebo) in the clinical trials for the preventive treatment of migraine were nasopharyngitis and hypersensitivity. In PROMISE-1 and PROMISE-2, 1.9 percent of patients treated with eptinezumab discontinued treatment due to adverse reactions.

Eptinezumab offers patients with migraine a preventive treatment administered as one 30-minute IV infusion 4 times a year (every three months). The recommended dosage is 100 mg, and some patients may benefit from a dosage of 300 mg. Dosing should be based on the guidance in the Prescribing Information and Patient Information.

VYEPTI (eptinezumab-jjmr) was approved by the U.S. Food and Drug Administration (FDA) for the preventive treatment of migraine in adults in February 2020, and in January 2022, eptinezumab was granted marketing authorization by the European Commission (EC) for the prophylaxis of migraine in adults who have at least four migraine days per month. Today, eptinezumab is launched in more than 30 markets worldwide.

About Migraine Disease

Migraine is a complex and disabling neurological disease that limits functionality and quality of life.[2],[3] It is characterized by moderate to severe head pain typically accompanied by an array of symptoms, including nausea, vomiting and sensitivity to light or sound.[2] Over time, migraine disease may worsen, with attacks increasing in frequency, severity and duration.[4] It is estimated to affect more than 40 million people in the U.S. and impacts three times as many women than men.[5] Headache disorders are a leading cause of years lived with disability (YLD) among all diseases and is a top 5 cause for 10-24-year-olds, according to the 2019 Global Burden of Disease study.[6] The impact of migraine permeates into career, home life and relationships.[7]

About INFUSE study

The INFUSE study is a 12-month, prospective, observational study in the US, assessing real-world effectiveness of IV eptinezumab (100 mg or 300 mg) in adults with migraine who previously failed at least one preventive anti-CGRP. Data were collected digitally at baseline, Day 7, and Months 3, 6, 9 and 12 through participant-reported surveys. The primary outcome was percent of patients with «much» or «very much» improved on the 7-point PGIC scale («very much improved,» «much improved,» «minimally improved,» «no change,» «minimally worse,» «much worse,» or «very much worse»). Secondary outcomes included monthly headache days and ≥50% reduction in monthly headache days (MIDAS-derived) and number of patient-defined «good days». INFUSE did not collect safety data but these data are reported via the established safety reporting channels.
