Avanir Pharmaceuticals Provides Business Update and Announces Restructuring Plan

ALISO VIEJO, Calif.—Avanir Pharmaceuticals (NASDAQ: AVNR) today provided updates on its two license and collaboration agreements and announced certain restructuring activities intended to better enable the Company to execute on its plan to pursue regulatory approval for Zenvia™.

First, Avanir announced that Novartis has assumed all continuing research and development activities for the Macrophage Migration Inhibitor Factor (MIF) program with plans to advance the lead candidate, AVP-28225 towards clinical development. The two companies have been involved in a two-year research collaboration to identify orally active, small molecule inhibitors of MIF for the treatment of inflammatory diseases. Avanir will receive a milestone payment if the molecule reaches the next stage of development and is eligible to receive additional milestone payments through clinical development. “We are extremely pleased with the outcome of the research collaboration as well as the decision by Novartis to move the lead candidate forward. This could someday become an important new therapy for patients suffering from inflammatory diseases,” said Randall Kaye, MD, Chief Medical Officer of Avanir.

Second, the Company also announced that it and AstraZeneca have mutually agreed to end their research collaboration and license agreement on the Reverse Cholesterol Transport (RCT) enhancing compounds. According to the terms of the agreement, AstraZeneca will return the lead molecule and return or make available all related rights to Avanir.

In conjunction with the winding down of these two research collaborations, the Company has initiated planned restructuring activities to reduce ongoing operational costs and account for the loss of revenue associated with the two research collaborations. Avanir anticipates that it will exit from the San Diego research facility later this year and move essential clinical development and support resources to the Company’s Orange County, Calif. headquarters. With these actions and other cost-saving measures, the company is targeting to reduce its annual operating expenses to $20 million once all of these actions are fully implemented.

Avanir today also reported it has received expressions of interest in certain Company assets, including several investigational compounds as well as FazaClo(R), and is engaged in ongoing discussions with multiple parties regarding their potential sale.

“We are working aggressively to solidify our financial position in order to fund the Company’s ongoing operations,” said Keith Katkin, Avanir’s President and CEO. “We are evaluating several strategic options simultaneously and no option is being ruled out at this time. Our goal is to minimize shareholder dilution and obtain sufficient cash to fund all, or substantially all, of the operating expenses for the next two years, including the estimated costs of the confirmatory Phase III trial for Zenvia™. Once we have more definitive results from our discussions with the interested parties, we will report back to our shareholders,” added Mr. Katkin.
