About AVANIR

AVANIR Pharmaceuticals is focused on acquiring, developing, and commercializing novel therapeutic products for the treatment of chronic diseases. AVANIR's products and product candidates address therapeutic markets that include the central nervous system, inflammation, and infectious diseases. AVANIR's lead product candidate, Zenvia™, is being developed for the treatment of pseudobulbar affect (PBA) and is the subject of an approvable letter from the U.S. Food and Drug Administration (FDA) for that indication. The Company has initiated a confirmatory Phase III study under a Special Protocol Assessment (SPA) agreement with the FDA utilizing a new lower quinidine dose formulation of Zenvia intended to address safety concerns raised in the Agency's approvable letter for Zenvia in the treatment of PBA. Additionally, in April 2007 AVANIR announced meeting all primary endpoints in a Phase III clinical trial with Zenvia in patients with diabetic peripheral neuropathic (DPN) pain. In May 2008 the Company released top-line results of a formal pharmacokinetic (PK) study that identified alternative lower-dose quinidine formulations of Zenvia for DPN pain intended to deliver similar efficacy and improved safety/tolerability versus the formulations previously tested for this indication. AVANIR has licensed its MIF inhibitor program to Novartis International Pharmaceuticals Ltd. and has sold its anthrax monoclonal antibody program to Emergent BioSolutions. The Company's first commercialized product, Abreva®, is marketed in North America by GlaxoSmithKline Consumer Healthcare and is the leading over-the-counter product for the treatment of cold sores.
