AVANIR Pharmaceuticals Announces Sale of FazaClo to Fund Continued Development of Zenvia

Total proceeds of up to $54 million

Personnel changes also announced in conjunction with the transaction

AVANIR Pharmaceuticals (NASDAQ:AVNR) today announced that it has signed a definitive agreement to sell its currently marketed antipsychotic drug FazaClo® (clozapine, USP) to Azur Pharma, a specialty pharmaceutical company headquartered in Ireland. FazaClo is indicated for the management of severely ill schizophrenic patients who fail to respond adequately to standard drug treatments for schizophrenia. FazaClo is also indicated for reducing the risk of recurrent suicidal behavior in patients with schizophrenia or schizoaffective disorder.

Under terms of the agreement, AVANIR will receive approximately $42 million at the close of the transaction with up to an additional $10 million in contingent payments in 2009. In addition, AVANIR will receive up to $2 million in royalties, based on 3% of annual net product revenues in excess of $17 million. AVANIR's earn-out obligations that would have been payable to the prior owner of Alamo Pharmaceuticals upon the achievement of certain sales milestones will be assumed by Azur Pharma. AVANIR has agreed to transfer or assign all FazaClo business operations including marketing, sales and medical affairs infrastructure as well as manufacturing agreements to Azur Pharma following the completion of the transaction. The agreement is subject to customary closing conditions and is expected to close by early August 2007.

"The divestiture of FazaClo marks an important step forward in our corporate strategy to direct our resources toward the Zenvia development programs," said Keith Katkin, AVANIR's President and CEO. "This strategic move raises significant capital without shareholder dilution and enhances our current cash position. We will use $11 million of the sales proceeds to pay down a portion of our outstanding notes and believe our remaining net available funds will be sufficient to finance operating expenses for at least the next year, including funding the initiation of both our planned confirmatory Phase III clinical trials of Zenvia in patients with involuntary emotional expression disorder (IEED) and with diabetic peripheral neuropathic (DPN) pain."

"We have accomplished a great deal since acquiring FazaClo just over a year ago for $29 million plus $4 million in contingent run rate notes. Our commercial team successfully executed on marketing and sales activities that resulted in a significant increase in total prescriptions as well as our prescriber base," said Gregory Flesher, Executive Director of Business Development. "Despite this growth, the acquisition of FazaClo in May of 2006 was always intended to complement the Zenvia launch and its divestiture will now enable us to further invest in the clinical development of our core asset Zenvia. We are placing FazaClo into a highly competent organization and patients with schizophrenia will continue to benefit from this important medication."

In light of the reduced operating infrastructure anticipated following the sale of FazaClo, the Company announced that Mike Puntoriero, Senior Vice President and Chief Financial Officer, will be resigning his position with AVANIR effective July 11, 2007. Martin Sturgeon, AVANIR's Chief Accounting Officer, who has been with AVANIR since February 2007, will assume the role of Interim Chief Financial Officer. "I would like to thank Mike for his leadership over the past several months and we wish him much success in his future endeavors," said Mr. Katkin.
