BOTHELL, Wash., June 26, 2014 (GLOBE NEWSWIRE) -- Alder BioPharmaceuticals, Inc. ("Alder") (Nasdaq:ALDR), a clinical-stage biopharmaceutical company developing monoclonal antibody therapeutics for the treatment of migraine, autoimmune and inflammatory diseases, today announced Peter J. Goadsby, M.D., Ph.D., director, NIHR-Wellcome Trust Clinical Research Facility, King's College London and director, Headache Center, Department of Neurology, University of California, San Francisco, and David W. Dodick, M.D., professor of neurology at the Mayo Clinic, will present results from a randomized, double-blind, placebo-controlled, proof-of-concept clinical trial of ALD403 for the prevention of frequent episodic migraine at the 56th Annual Scientific Meeting of the American Headache Society at the Hyatt Regency Century Plaza in Los Angeles, California.

Key points:

  • The poster presentation, "Randomized, Double-blind, Placebo-controlled Trial of ALD403: An Anti-CGRP Peptide Antibody in the Prevention of Frequent Episodic Migraine," will be displayed from 11:30 a.m., Thursday, June 26 until 4:30 p.m., Saturday, June 28.
  • Drs. Goadsby and Dodick will present the poster, Late Breaking Poster 7 (LBP7), in the California Showroom between 12:30 p.m. and 2:00 p.m., Saturday, June 28.
  • ALD403 met the primary endpoint of the study, significantly reducing mean migraine days per month versus placebo.
  • A single infusion of ALD403 resulted in a 100% decrease in migraine days per month for 27-41% of patients depending on month observed.
  • ALD403 was well tolerated and there were no differences from placebo in terms of adverse events or laboratory safety data.
  • ALD403 is a genetically engineered monoclonal antibody that targets CGRP for prevention of migraine. Calcitonin gene-related peptide (CGRP) is a small protein involved in the transmission of and heightened sensitivity to pain experienced in migraine.
