Alder BiopharmaTo Present Data From Eptinezumab Development Program At 18th Congress Of The International Headache Society

BOTHELL, Wash., Sept. 07, 2017 (GLOBE NEWSWIRE) -- Alder BioPharmaceuticals, Inc. (NASDAQ:ALDR), a clinical-stage biopharmaceutical company developing monoclonal antibody therapeutics, today announced that eptinezumab, the company’s investigational product candidate for migraine prevention, will be the subject of seven scientific presentations at the 18th Congress of the International Headache Society (IHC) being held September 7-10, 2017 in Vancouver, Canada.

The eptinezumab presentations will feature detailed clinical results from Alder’s PROMISE 1 Phase 3 clinical trial evaluating patients with frequent episodic migraine, as well as additional data analyses of Alder’s Phase 2b clinical trial evaluating patients with chronic migraine, including data of patient-reported outcomes, reduced triptan use and reductions in migraine on the first day post-infusion.

“Physicians today are limited in their ability to meet their migraine patients’ treatment needs because preventive therapeutic options take weeks to months to work and have tolerability and/or safety issues, which limits their efficacy potential,” said Roger K. Cady, M.D., vice president of neurology of Alder. “We are excited about our data presentations at IHC, which we believe will support the potential benefits of eptinezumab’s unique clinical profile and infusion delivery. These data include prevention benefit day 1 post infusion and an average of 1 in 5 patients with no migraines in any given month. We believe these clinical results may represent a new standard for migraine prevention. We look forward to sharing our data at IHC.”

Eptinezumab is a monoclonal antibody discovered and developed by Alder BioPharmaceuticals for migraine prevention. Eptinezumab is administered quarterly via infusion that allows for 100% of the dose available to selectively and potently inhibit CGRP¹. Eptinezumab is currently in Phase 3 studies, including PROMISE 1 and PROMISE 2, to assess its efficacy and safety in migraine prevention. Over 1,600 people have been treated with eptinezumab in clinical trials.

About Migraine^2,3,4
Migraine affects 36 million Americans and is considered the 6th most debilitating disease in the world. It is a disabling neurological disease characterized by recurrent episodes of moderate to severe headache accompanied by nausea, vomiting, and sensitivities to light and sound. 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. 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 there is a significant need for new, effective, and well-tolerated treatment options.

About Alder BioPharmaceuticals, Inc.
Alder BioPharmaceuticals, Inc. is a clinical-stage biopharmaceutical company committed to transforming the treatment paradigm for patients with migraine and other serious neurological or inflammatory conditions. Leveraging its pioneering monoclonal antibody technologies, Alder discovers and develops novel therapeutic antibodies designed to deliver highly differentiated, best-in-class clinical profiles. Alder's lead pivotal-stage product candidate, eptinezumab, is being evaluated for migraine prevention. Eptinezumab is a monoclonal antibody administered quarterly via infusion that allows for 100% of the dose available to selectively and potently inhibit the calcitonin gene-related peptide (CGRP), a protein that is active in mediating the initiation of migraine. Alder is additionally evaluating ALD1910, a preclinical product candidate also in development as a migraine prevention therapy. ALD1910 is a monoclonal antibody that inhibits pituitary adenylate cyclase-activating polypeptide-38 (PACAP-38), another protein that is active in mediating the initiation of migraine. Clazakizumab, Alder's third program, is a monoclonal antibody candidate that inhibits interleukin-6 and is licensed to Vitaeris, Inc. For more information, please visit http://www.alderbio.com.
