About AVANIR

AVANIR Pharmaceuticals is focused on developing, acquiring 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 (CNS), 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. AVANIR has obtained a Special Protocol Assessment from the FDA covering the design of a single confirmatory Phase III clinical trial testing lower-dose formulations of Zenvia in patients with PBA to address issues raised by the approvable letter. The Company expects to enroll the first PBA patient into this trial by the end of the 2007 calendar year. 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. The Company plans to conduct a formal pharmacokinetic (PK) study to assess alternative lower-dose quinidine formulations of Zenvia for DPN pain that are intended to deliver similar efficacy and improved safety/tolerability versus the formulations previously tested for this indication. AVANIR has also licensed a compound to Novartis International Pharmaceuticals Ltd. for the treatment of inflammatory disease. AVANIR's infectious disease drug candidate, AVP-21D9, is a human monoclonal antibody in pre-clinical development for the treatment of anthrax with funding provided to date from NIH/NIAID grants. 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.
