Alder BioPharmaceuticals® New Data Demonstrated Eptinezumab Increased Migraine-Free Intervals (Up to 32.5 days) and Improved Quality-of-Life Outcomes in Patients with Episodic Migraine
BOTHELL, Wash., April 25, 2018 -- Alder BioPharmaceuticals, Inc. (NASDAQ:ALDR), a biopharmaceutical company focused on developing novel therapeutic antibodies for the treatment of migraine, today announced new data from its PROMISE 1 Phase 3 clinical trial evaluating eptinezumab, Alder’s lead investigational product candidate for migraine prevention, in patients with episodic migraine. The clinical data demonstrated that following a quarterly infusion of eptinezumab, patients experienced a significant reduction in migraine days and improved quality-of-life outcomes. Detailed results will be presented today at the 70th Annual American Academy of Neurology Meeting in Los Angeles.
“Today, a patient’s quality of life is limited by the fear of a potential migraine, which severely impacts their activities of daily living, family life and careers,” said Roger K. Cady, M.D., vice president of neurology of Alder. “The significant periods of freedom from migraine delivered in the trial represents a compelling attribute of eptinezumab’s clinical profile. These notable improvements reinforce our confidence in eptinezumab’s potential to be an important treatment option in migraine prevention.”
“The significant increase in monthly migraine-free days demonstrate the potential relief that eptinezumab can deliver to migraine patients,” said Dr. Richard Lipton, Director of the Montefiore Headache Center, Albert Einstein College of Medicine. “Further, as demonstrated by the quality of life survey results, patients experienced improvements in areas such as bodily pain and physical function, illustrating the opportunity eptinezumab may provide to patients suffering from migraine.”
The observed safety profile for PROMISE 1, to date, is consistent with previously reported eptinezumab studies. The most commonly reported adverse events occurring at an incidence of 5 percent or greater across all eptinezumab treatment groups were upper respiratory infection (10.5 percent), nasopharyngitis (common cold) (6.8 percent) and sinusitis (3.6 percent).
About Eptinezumab PROMISE Clinical Trial Program
PROMISE 1 (PRevention Of Migraine via Intravenous eptinezumab Safety and Efficacy 1) was a Phase 3 randomized, double-blind, placebo-controlled global trial evaluating the safety and efficacy of eptinezumab for episodic migraine prevention. In the study, 888 patients were randomized to receive eptinezumab (300 mg, 100 mg or 30mg), or placebo administered by infusion once every 12 weeks. To be eligible for the trial, patients must have experienced £14 headache days per month, of which at least four met the criteria for migraine. The primary endpoint was the mean change from baseline in monthly migraine days over the 12 week, double-blind treatment period. In June 2017, Alder announced that eptinezumab met the primary endpoint and key secondary endpoints in PROMISE 1 with very high statistical significance. See the press release for more information.
PROMISE 2 (PRevention Of Migraine via Intravenous ALD403 Safety and Efficacy 2) is a Phase 3, randomized, double-blind, placebo-controlled global trial evaluating the safety and efficacy of eptinezumab for chronic migraine prevention. In the study, 1,072 patients were randomized to receive eptinezumab (300 mg or 100 mg), or placebo administered by infusion once every 12 weeks. To be eligible for the trial, patients must have experienced at least 15 headache days per month, of which at least eight met criteria for migraine. Patients that participated in the trial had an average of 16.1 migraine days per month at baseline. The primary endpoint was the mean change from baseline in monthly migraine days over the 12 week, double-blind treatment period. Secondary study endpoints assessed through 12 weeks included reduction in migraine prevalence day 1 and days 1-28, reduction of at least 50%, 75%, and 100% from baseline in mean monthly migraine days, change from baseline in mean monthly acute migraine-specific medication days, and reductions from baseline in patient-reported impact scores on the Headache Impact Test (HIT-6). In January, Alder announced that eptinezumab met the primary endpoint and key secondary endpoints in PROMISE 2 with very high statistical significance. See the press release for more information.
Eptinezumab is an investigational monoclonal antibody discovered and developed by Alder BioPharmaceuticals for migraine prevention. Eptinezumab is the only potent and selective anti-CGRP mAb administered by quarterly infusion for migraine prevention, delivering 100% bioavailability to immediately inhibit CGRP.2 Eptinezumab has been studied in several global, randomized, double-blind, placebo-controlled studies to assess its safety and efficacy in migraine prevention.
Migraine affects 36 million Americans2 and, worldwide, is considered the sixth-leading cause of days with disability3 and the third-leading cause of disability of people under the age of 50.4 The occurrence of migraine can be unpredictable with a profound impact on activities of daily living. This disease can last decades, often during what should be the most productive years of patients’ lives.2 Migraine can remit or progress to chronic migraine over time and persist as chronic migraine for years or decades, but it commonly oscillates between periods of frequent episodic and chronic migraine. Current preventive treatments for migraine fail to meet the needs of most patients and most patients discontinue use within 6 months to 1 year due to lack of efficacy and/or side effects.5,6 There is a significant need for new, effective, and well-tolerated treatment options.
About Alder BioPharmaceuticals, Inc.
Alder BioPharmaceuticals is a clinical-stage biopharmaceutical company focused on transforming the migraine treatment paradigm through the discovery, development and commercialization of novel therapeutic antibodies. Alder’s lead product candidate, eptinezumab, is a monoclonal antibody (mAb) that inhibits calcitonin gene-related peptide (CGRP) and is currently in late-stage clinical development for the prevention of migraine. Unlike other CGRP inhibitors, eptinezumab was specifically designed as an infusion therapy to address significant patient need. Alder is also developing ALD1910, a preclinical mAb that inhibits pituitary adenylate cyclase-activating polypeptide-38 (PACAP-38) for migraine prevention.
