Avanir Pharmaceuticals Announces Publication of Pivotal Phase III Results from AVP-825 Acute Migraine Study in the Journal "Headache"

ALISO VIEJO, Calif., Oct. 30, 2014 /PRNewswire/ -- Avanir Pharmaceuticals, Inc. (NASDAQ: AVNR) today announced the publication of results from TARGET, a pivotal phase III study evaluating the efficacy and safety of AVP-825 22mg in the January 2015 issue of Headache (Early access is now available). AVP-825 is an investigational drug-device combination product consisting of low-dose sumatriptan powder (22mg) delivered intranasally utilizing a novel Breath Powered™ delivery technology, for the acute treatment of migraine. A New Drug Application (NDA) for AVP-825 has been accepted and is currently under review by the U.S. Food and Drug Administration (FDA) with a Prescription Drug User Fee Act (PDUFA) goal date of November 26, 2014.

"Some studies indicate that nearly half of the 37 million Americans suffering from migraines are dissatisfied with their current treatment. We believe AVP-825 could provide a targeted, fast acting migraine treatment option by combining low-dose sumatriptan, the most widely used prescription migraine medication, with an innovative delivery method," said Joao Siffert, MD, chief medical officer for Avanir. "We are pleased to have the pivotal trial data published in a reputable medical journal and look forward to the upcoming FDA decision in November and to potentially being able to offer a new migraine treatment to patients in need."

The TARGET study data demonstrated relief of moderate or severe migraine headache as quickly as 15 minutes (19.4% AVP-825 vs. 14.4% placebo device) in subjects receiving AVP-825). A significantly greater proportion of AVP-825 patients reported headache relief at 30 minutes (41.7% vs. 26.9%, P=0.03) and at every time point up to two hours post-dose compared with those using the placebo device (67.6% vs. 45.2%, P=0.002).  Relief was sustained through 24 and 48 hours in a greater proportion of patients who received AVP-825 vs. placebo. The treatment was well tolerated with a low incidence of adverse events (AEs), with the most common AEs being product taste (22%), nasal discomfort (13%), and rhinitis (3%); local AEs were transient and almost exclusively mild to moderate in severity.

About the Phase III TARGET Study

In this multicenter, double-blind, placebo-controlled study, 230 migraine sufferers were randomized to self-administer either AVP-825 or placebo using the Breath Powered device when they had moderate to severe migraine pain. Pain scores were then assessed at various time points after administration. Pain was evaluated using a four point scale with headache relief defined as a reduction from moderate (grade 2) or severe (grade 3) pain to mild (grade 1) or complete relief (grade 0).

About AVP-825
AVP-825 is an investigational drug-device combination product consisting of low-dose sumatriptan powder (22mg) delivered intranasally utilizing a novel Breath Powered delivery technology. If approved, AVP-825 would be the first and only fast-acting, dry-powder intranasal form of sumatriptan for the treatment of migraine. AVP-825 is an investigational drug-device combination product not approved by the FDA. Sumatriptan is contraindicated for certain patients, including those with a history of coronary artery disease (CAD) or coronary vasospasm.

The Breath Powered delivery technology is activated by user's breath to propel medications deep into the nasal cavity where absorption is more efficient and consistent. The user exhales into the device, automatically closing the soft palate and sealing off the nasal cavity. Through a sealing nosepiece placed into the nostril, the exhaled breath carries medication from the device directly into one side of the nose. Narrow nasal passages are gently expanded and medication is dispersed deep into the nasal cavity reaching areas where it can be rapidly absorbed. As the medication is delivered, the air flows around to the opposite side of the nasal cavity and exits through the other nostril. Closure of the soft palate helps prevent swallowing or inhalation of sumatriptan powder into the lungs.
