• The intravenous (IV) part of the phase IIb dose-finding PROCEED trial of bocunebart (Lu AG09222) met its primary endpoint in migraine prevention, demonstrating a statistically significant difference to placebo in the change from baseline in the number of monthly migraine days (MMDs) over weeks 1 to 12 in a population that experienced past treatment failures.
• The results demonstrate the potential of bocunebart in severe migraine.
• Additional analyses will be done to better understand the dose-response relationship across the investigated doses.
• Based on this positive outcome, Lundbeck will approach regulatory authorities to discuss the results and phase III design options.

Valby, Denmark, February 12, 2026 - H. Lundbeck A/S (Lundbeck) announced positive results, meeting its primary endpoint, in the multiple IV dosing part of PROCEED, an adaptive phase IIb dose-finding and route of administration trial of bocunebart (Lu AG09222). The trial investigated bocunebart as a potential treatment for the prevention of migraine in a population that experienced 1-4 previous preventive treatment failures in the past 10 years (NCT06323928). Bocunebart was generally well tolerated, and no new safety signals were detected during the PROCEED trial.

These data build on findings from the previously successful HOPE phase IIa trial evaluating single IV administration of bocunebart. 

"I am encouraged by the positive results from the PROCEED trial. The efficacy demonstrated in this trial represent a promising advancement in the treatment of migraine, offering hope to many patients suffering from this debilitating condition," said the coordinating investigator of the trial, Dr. Jessica Ailani, certified headache specialist, Washington DC.

Dr. Johan Luthman, EVP and Head of Research & Development in Lundbeck, said:
"This milestone is a testament to our commitment to advancing brain health with innovative treatments that focus on addressing significant unmet medical needs. These data underline Lundbeck's ambition to deliver the first PACAP targeting option in migraine prevention. With its novel mechanism of action, it has the potential to become an important addition to the migraine treatment paradigm, furthering Lundbeck's mission to improve outcomes for people living with severe migraine."

Lundbeck is grateful to all the participants with migraine, their families, and the investigators who participated in the trial and contributed greatly to this research.

The trial results are planned to be presented at an upcoming conference and submitted for scientific publication at a later date.

About the PROCEED migraine trial

The PROCEED trial assessed the efficacy, safety, and tolerability of bocunebart versus placebo when administered once monthly for three months. The PROCEED trial aimed to establish the optimal dose and route of administration, subcutaneous and IV, of bocunebart. In the IV part of PROCEED a total of 431 patients from 14 countries (Bulgaria, Czechia, Denmark, France, Georgia, Germany, Hungary, Lithuania, Japan, Poland, Romania, Slovakia, Spain, and the United States) were randomized. The primary efficacy endpoint was defined as the difference between bocunebart and placebo in the mean change from baseline in the number of monthly migraine days over weeks 1 to 12.

The target population for this trial was defined as patients diagnosed with migraine as outlined in the International Classification of Headache Disorders Third Edition (ICHD-3)^[i] and with treatment failure of 1-4 different preventive migraine medications in the past 10 years.

About bocunebart

Bocunebart is an investigational monoclonal antibody (mAb) with a novel mechanism of action. It is engineered to bind to and inhibit the signaling of pituitary adenylate cyclase-activating polypeptide (PACAP), a neuropeptide implicated in migraine pathophysiology. This mechanism operates through a pathway distinct from that targeted by anti-calcitonin gene-related peptide (anti-CGRP) therapies[ii]. Bocunebart represents a potential new treatment class and could provide an alternative option for migraine prevention, offering hope to individuals severely affected by the condition.

Bocunebart is an investigational compound, not approved by the US Food and Drug Administration (FDA) or any other regulatory agency, and the efficacy and safety of bocunebart have not been established.

About migraine

Migraine is a complex and incapacitating neurological disease characterized by recurrent episodes of moderate to severe, pulsating headaches typically accompanied by an array of symptoms, including nausea, vomiting, and sensitivity to light and sound^[iii]. As the most prevalent neurological disorder in people aged <50 years, migraine imposes both a social and financial burden, affecting around 135 million people in the G7 countries plus China. Repeated migraine attacks, and often the constant fear of the next one, damage family life, social life and work life^[iv].
