Alder to Present Migraine Prevention Data for Eptinezumab at 59th Annual Scientific Meeting of the American Headache Society

BOTHELL, Wash., June 07, 2017 (GLOBE NEWSWIRE) -- Alder BioPharmaceuticals, Inc. (NASDAQ:ALDR), today announced four data presentations at the 59th Annual Scientific Meeting of the American Headache Society in Boston from June 8-11, 2017. The presentations will highlight Phase 2b clinical data and analyses for eptinezumab (formerly ALD403), Alder's investigational monoclonal antibody currently in Phase 3 clinical trials for migraine prevention.

"Alder is excited to present some of the encouraging eptinezumab clinical data observed to date, which we believe continues to support eptinezumab as a potential therapy for migraine prevention, including meaningful migraine prevention activity within 24 to 48 hours following a single administration," said Randall C. Schatzman, Ph.D., president and chief executive officer of Alder. "We expect to announce top-line results from PROMISE 1, our pivotal Phase 3 trial evaluating eptinezumab in patients living with frequent episodic migraine, before the end of the month. We are focused on moving efficiently through our second Phase 3 pivotal trial, PROMISE 2, and toward a BLA submission in the second half of 2018."

About Eptinezumab
Eptinezumab, formerly ALD403, is Alder's lead pivotal-stage investigational product candidate in development as a migraine prevention treatment for patients with chronic and frequent episodic migraine. Eptinezumab is a novel monoclonal antibody that inhibits the calcitonin gene-related peptide, or CGRP, a small protein involved in the transmission of, and heightened sensitivity to, pain experienced in migraine.
