ALD-1910

PROCEED is an adaptive Phase IIb trial with Lu AG09222, an investigational mAb intended to block signaling by pituitary adenylate cyclase-activating polypeptide (PACAP), a neuropeptide that is believed to contribute to migraine. The PROCEED trial is designed to explore different doses and routes of administration of Lu AG09222 in patients with migraine for whom one to four previous preventive treatments had failed to provide a benefit. Following the recruitment of approximately 75% of the patients in a subcutaneously (SC) administration dose-finding part of PROCEED, a pre-specified interim analysis is triggering an expansion of the trial, by the initiation of an intravenously (IV) dose-finding part. VALBY, Denmark, March 31, 2025 /PRNewswire/ -- H. Lundbeck A/S (Lundbeck) is announcing reaching 75% recruitment target in the SC dose-finding part (Part A) in the phase IIb PROCEED trial, that explores dose and route of administration of the anti-PACAP mAb Lu AG09222. Based on a pre-specified interim outcome assessment following SC route of administration, Lundbeck will now expand PROCEED to obtain further IV dose-response information on Lu AG09222 in migraine prevention, building further on findings from the previously successful HOPE Phase IIa trial evaluating IV administration of Lu AG09222. Lundbeck can leverage its already established IV clinical infusion infrastructure for migraine prevention. Despite the advancements in migraine treatment, there remains a significant unmet need in migraine management, with an estimated 2.5 to 3.0 million patients in the G7 countries who are inadequately treated with currently approved treatments. Lu AG09222 has, through its binding to PACAP, the potential to become a first in class migraine preventive treatment. The PROCEED trial is expected to be completed in the first half of 2026 with planned pivotal phase III initiation in second half of 2026. About the PROCEED trial Lundbeck initiated the PROCEED Phase IIb trial March 2024. PROCEED is an interventional, randomized, double-blind, parallel-group, placebo-controlled, dose-finding phase IIb trial that is conducted in Europe, Japan, and the U.S. The target population for this trial is defined as patients diagnosed with migraine as outlined in the International Classification of Headache Disorders Third Edition (ICHD-3)ii and with treatment failure of 1-4 different preventive migraine medications in the past 10 years. The PROCEED trial assesses the efficacy, safety, and tolerability of Lu AG09222 versus placebo, when administered once monthly for three months. The PROCEED trial is intending to establish the optimal route of administration and dose of Lu AG09222, through an adaptive design consisting of a Part A, in which Lu AG09222 is administered SC and an optional Part B, in which Lu AG09222 is given IV. The initiation of the Part B, IV dose-response exploration in PROCEED is based on a pre-specified futility interim analysis of Part A, when about 75% of the patients have been randomized. About Lu AG09222 Lundbeck is developing Lu AG09222, an investigational monoclonal antibody (mAb) with an innovative mode of action, designed to bind and inhibit pituitary adenylate cyclase-activating polypeptide (PACAP)[i]. PACAP has emerged as a neuropeptide implicated in the pathophysiology of migraine and represents a novel target in migraine. Lu AG09222 represents a potential new therapeutic option, targeting a pathway in migraine that is distinct from the CGRP pathway. 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[ii]. 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[iii]. Contacts About H.

On September 4th, an article titled "A Monoclonal Antibody to PACAP for Migraine Prevention" was published in the latest issue of The New England Journal of Medicine. The article reported on Phase 2 clinical trial data for the use of the monoclonal antibody Lu AG09222ALD-1910 targeting pituitary adenylate cyclase-activating polypeptide (PACAP) in the treatment of migraine. It is reported that Lu AG09222(ALD-1910), a monoclonal antibody against PACAP, was originally developed by Lundbeck Seattle BioPharmaceuticals (LSBP). It functions by inhibiting the signaling pathways mediated by multiple G protein-coupled receptors (GPCRs) downstream of PACAP. In 2019, the Danish pharmaceutical company H. Lundbeck acquired LSBP and, consequently, took ownership of one of their products. Lundbeck continued to advance the clinical development of this product for migraine treatment. According to updated Phase 1 clinical trial data from 2023, healthy participants who received injections of Lu AG09222 + PACAP38 showed that Lu AG09222 inhibited PACAP38-induced dilation of head blood vessels and an increase in heart rate, and also reduced the associated headaches. These findings suggest that Lu AG09222 could be a potential treatment method for migraines and other PACAP-mediated diseases. In this Phase 2, double-blind, randomized, placebo-controlled trial reported by the New England Journal of Medicine (NEJM), subjects were adults aged 18 to 65 years old with migraines, who had not benefited from 2 to 4 previous preventive treatments. Participants were randomly assigned in a 2:1:2 ratio to receive a single dose infusion of 750 mg Lu AG09222, 100 mg Lu AG09222, or a placebo. The results showed that a total of 237 participants enrolled, with 97 receiving 750 mg Lu AG09222, 46 receiving 100 mg Lu AG09222, and 94 receiving the placebo. The average number of migraine days per month at baseline across the entire population was 16.7 days. In the 750 mg Lu AG09222 group, the average change from week 1 to 4 was a reduction of 6.2 days, compared to a reduction of 4.2 days in the placebo group (difference of 2.0 days; 95% confidence interval, -3.8 to -0.3; P=0.02). In terms of safety, during a 12-week observation period, the more common adverse events in the 750 mg Lu AG09222 group compared to the placebo group included COVID-19 (7% vs. 3%), nasopharyngitis (7% vs. 4%), and fatigue (5% vs. 1%). According to reports, migraine is a common chronic cerebrovascular neurological disorder that significantly impacts both individuals and society. It affects approximately one billion people worldwide and is characterized by recurrent, highly disabling episodes accompanied by severe headaches, nausea, vomiting, extreme sensitivity to light and sound, and various other physical, mental, and psychological signs and symptoms. Traditionally, the pathway involving CGRP (Calcitonin Gene-Related Peptide) and its receptors is considered one of the key pathways for migraine treatment, with several drugs already approved for marketing. In addition to this, targets like 5-HTR (5-Hydroxytryptamine Receptors) and COX (Cyclooxygenase) are also potential targets for clinical drug development. The article mentions PACAP (Pituitary Adenylate Cyclase-Activating Polypeptide) as an emerging potential target for migraine treatment. Besides the monoclonal antibodies mentioned in the article currently in Phase II clinical trials, Eli Lilly's development of Vipalanebart is also in Phase II clinical study stage. The differences in treating migraine with PACAP and CGRP are highlighted. How to obtain the latest research advancements in the field of biopharmaceuticals?
