AVANIR Strengthens Its Sales and Marketing Team.

SAN DIEGO -- AVANIR Pharmaceuticals (AMEX:AVN) today announced that it has appointed Keith Katkin as its Senior Vice President, Sales and Marketing and Eric Benevich as its Senior Director, Marketing, to further advance its plans for Neurodex(TM). Neurodex is the company's product candidate currently undergoing New Drug Application review at the Food and Drug Administration for the indication of pseudobulbar affect and being evaluated in a recently initiated Phase III clinical trial in patients with diabetic neuropathic pain. Both of these positions are newly created.

Keith Katkin will lead the team further developing the sales and marketing capabilities of AVANIR. Initially the senior members of the team will be both AVANIR's Senior Vice President, Corporate Development, (David Hansen) and its Vice President, Commercial Development (Gus Fernandez, Pharm. D.) in addition to Eric Benevich and a to-be-recruited Director, National Sales.

Most recently, Mr. Katkin served as the Vice President, Commercial Development for Peninsula Pharmaceuticals, playing a key role in the sale of Peninsula to Johnson & Johnson. Mr. Katkin's product launch and brand management experience on products such as Neupogen, Neulasta, and Biaxin will be especially valuable to AVANIR during its planned transformation into a fully integrated pharmaceutical company. Prior to his tenure at Peninsula, Mr. Katkin held Sales and Marketing positions with InterMune, Amgen and Abbott Laboratories.

Mr. Benevich, most recently Senior Director, Marketing at Peninsula Pharmaceuticals, has over fourteen years of industry experience at Amgen, AstraZeneca, and Astra Merck in various marketing, market research, and sales roles. His extensive launch and brand management experience on products such as Prilosec, Epogen and Enbrel will be especially beneficial to AVANIR as it plans for the launch of its Neurodex product.

AVANIR Pharmaceuticals is a pharmaceutical company focused on developing and commercializing novel therapeutic products for the treatment of chronic diseases. AVANIR's product candidates address therapeutic markets that include central nervous system and cardiovascular disorders, inflammation, and infectious disease. AVANIR recently submitted to the FDA the last modules of its "rolling" new drug application for Neurodex(TM) for the treatment of pseudobulbar affect. Additionally, AVANIR has initiated a double-blind, placebo-controlled, multicenter, Phase III clinical trial of Neurodex in patients with diabetic neuropathic pain. Recently, AVANIR partnered its preclinical research and development program for inflammatory disease with Novartis. The Company's first commercialized product, Abreva(R), is marketed in North America by GlaxoSmithKline Consumer Healthcare and is the leading over-the-counter product for the treatment of cold sores.
