About Alder BioPharmaceuticals, Inc.

Alder BioPharmaceuticals, Inc., is a clinical-stage biopharmaceutical company that discovers, develops and seeks to commercialize therapeutic antibodies with the potential to meaningfully transform current treatment paradigms. ALD403, Alder's lead pivotal-stage product candidate being evaluated for migraine prevention, is a genetically engineered monoclonal antibody that inhibits calcitonin gene-related peptide (CGRP). CGRP is a small protein with a well-established role in the initiation, transmission and heightened sensitivity to migraine pain. Alder's second program, ALD1613, targets adrenocorticotropic hormone (ACTH) and is intended for the treatment of congenital adrenal hyperplasia and Cushing's disease. ALD1613 is undergoing Investigational New Drug (IND)-enabling preclinical studies, and an IND submission is planned for 2016. Additionally, clazakizumab, a monoclonal antibody therapeutic candidate discovered by Alder designed to block interleukin-6, is licensed to Vitaeris, Inc. For more information, please visit
