ALISO VIEJO, Calif.--(BUSINESS WIRE)----AVANIR Pharmaceuticals (NASDAQ: AVNR) today announced that Keith A.

Mr. Katkin joined Avanir in July of 2005 as Senior Vice President of Sales and Marketing and has served as a member of Avanir's Executive Management Team.

"The Board is pleased to announce Keith's appointment as President and CEO," said Craig Wheeler, a member of Avanir's board of directors. "Since arriving at Avanir, Keith has been deeply involved across the business. He led the build out of a fully integrated commercial organization, including the acquisition and integration of Alamo Pharmaceuticals, as the company prepared for the potential launch of Zenvia. His contributions to the company have been meaningful, and the board anticipates that Keith will continue to show his considerable leadership skills as he navigates the company toward the anticipated eventual approval of Zenvia for IEED and minimizes operating expenses during this time."

"I want to thank Eric for his past contributions and anticipated support for the Company in the transition," said Mr. Katkin.

About Zenvia

Zenvia is a combination of two well-characterized compounds, the active ingredient dextromethorphan, and the enzyme inhibitor quinidine, which serves to increase the bioavailability of dextromethorphan. The first-in-class drug candidate is believed to help regulate excitatory neurotransmission in two ways, through presynaptic inhibition of glutamate release via sigma-1 receptor agonist activity, and through postsynaptic glutamate response modulation via uncompetitive, low-affinity NMDA antagonist activity.
