ALISO VIEJO, Calif., June 5, 2013 /PRNewswire/ --Avanir Pharmaceuticals, Inc.
(NASDAQ: AVNR) today announced that the U.S. Food and Drug Administration
(FDA) has agreed to an expedited development pathway for their next-generation
compound, AVP-786, requiring only a limited pre-clinical package as part of
the Investigational New Drug (IND) application. Upon completion of these
preclinical studies the company intends to proceed directly into human
clinical trials.

"We are very pleased with the outcome of our recent meeting with the Division
of Neurology of the FDA," said Joao Siffert, MD, Avanir's chief scientific
officer. "Avanir will be allowed to reference the extensive data generated
during AVP-923 development programs in support of the AVP-786 IND and
subsequent new drug application. This has the potential to substantially
reduce the cost and time to market. We anticipate that we will be able to
seamlessly integrate AVP-786 into our ongoing development programs in
neuropathic pain, agitation in Alzheimer's disease and levodopa induced
dyskinesia in Parkinson's disease."

About AVP-786
AVP-786 is a novel investigational drug product consisting of a combination of
deuterium modified dextromethorphan (a new chemical entity or NCE) and
ultra-low dose quinidine, used as a metabolic inhibitor. Incorporation of
deuterium into specific positions of the dextromethorphan molecule strengthens
the chemical bonds and reduces susceptibility to enzyme cleavage and first
pass metabolism, but without altering its pharmacology. AVP-786 is an
investigational drug not approved by the FDA.

About AVP-923
AVP-923 is a combination of two well-characterized compounds, the active CNS
ingredient dextromethorphan hydrobromide (an uncompetitive NMDA receptor
antagonist and sigma-1 receptor agonist) plus low-dose quinidine sulfate (a
CYP2D6 enzyme inhibitor), which serves to increase the bioavailability of
dextromethorphan. AVP-923 is being studied in several ongoing clinical trials
including agitation in Alzheimer's disease, neuropathic pain in Multiple
Sclerosis, levodopa-induced dyskinesia in Parkinson's disease, and behavioral
symptoms of autism. AVP-923 for the above investigational uses has not been
approved by the FDA.
