Avanir Pharmaceuticals Announces Multiple Data Presentations Highlighting Its Central Nervous System (CNS) Therapeutics Franchise at the 66th Annual Meeting of the American Academy of Neurology
"Collectively these data reflect our commitment to advancing innovative medicines for treating central nervous system disorders with high unmet medical need such as PBA and migraine," said
New Data Demonstrate that NUEDEXTA may Provide Early PBA Symptom Remission
"Sudden, uncontrollable outbursts of crying or laughter negatively impact patients' quality of life and take an emotional toll on not only the patients but also their loved ones," said
New post-hoc analysis from the Phase III STAR Trial comparing NUEDEXTA to placebo in the treatment of PBA showed that 19 percent of patients treated with NUEDEXTA achieved remission from their PBA symptoms after only one-week of treatment. This percentage increased to approximately 50 percent achieving remission by the end of the 12-week trial. Throughout the trial, sustained episode remission rates in patients treated with NUEDEXTA were significantly higher compared to placebo. Remission was defined as no episodes for the remainder of the study and a minimum of 14 days prior to completion or drop-out.

New Data in Veterans with Traumatic Brain Injury (TBI) Highlights PBA Symptoms Impact on Quality of Life
New data from a first-of-its-kind study of PBA symptoms in veterans with mild TBI highlights the negative impact PBA symptoms have on quality of life, adding an extra burden to life post-TBI. In addition to patient burden, the data demonstrate that overall health care costs increased in these patients compared to TBI patients without PBA symptoms. Medication costs more than doubled in PBA symptom-positive veterans, and total outpatient healthcare costs were about 20% higher. These data highlight the need for developing a screening protocol for identifying PBA symptoms to help improve diagnosis, treatment and ultimately the quality of care for our nation's veterans. This study was conducted in collaboration with the

PBA May Be Often Overlooked or Misdiagnosed in Dementia Patients Adding to the Potential Disease Burden

"Dementia patients, including those with Alzheimer's disease, commonly suffer from depression and neurobehavioral symptoms. Excessive crying episodes may actually be symptoms of PBA which can be overlooked or misdiagnosed," said
AVP-825 Demonstrates Rapid Migraine Relief
"Migraine is well accepted as a neurologic disease that has debilitating consequences, and for which new treatments are needed that can provide fast and effective relief," said
In this multicenter, double-blind, placebo-controlled study, 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. The data show migraine headache relief for some patients began as early as 15 minutes after treatment, and a statistically significant greater number of patients receiving AVP-825 experienced headache relief compared to placebo at all time points from 30 minutes through two hours. At two hours after taking the medication, 7 out of 10 patients taking AVP-825 reported that they were experiencing meaningful relief from their migraine headache. In this study there were no serious adverse events associated with AVP-825.

Title: Efficacy and Safety of AVP-825, a Novel Breath-Powered™ Powder Sumatriptan Intranasal Treatment, for Acute Migraine

AVP-825 is an investigational drug-device combination product consisting of low-dose sumatriptan powder 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
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 than through most other routes. A user exhales into the device, automatically closing the soft palate and sealing off the nasal cavity completely. 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.
NUEDEXTA is an innovative combination of two well-characterized components; dextromethorphan hydrobromide (20 mg), the ingredient active in the central nervous system, and quinidine sulfate (10 mg), a metabolic inhibitor enabling therapeutic dextromethorphan concentrations. NUEDEXTA acts on four key receptors in the brain including sigma-1 and NMDA, although the mechanism by which NUEDEXTA exerts therapeutic effects in patients with PBA is unknown.
NUEDEXTA Important Safety Information
NUEDEXTA is indicated for the treatment of pseudobulbar affect (PBA). PBA occurs secondary to a variety of otherwise unrelated neurological conditions, and is characterized by involuntary, sudden, and frequent episodes of laughing and/or crying. PBA episodes typically occur out of proportion or incongruent to the underlying emotional state.
Studies to support the effectiveness of NUEDEXTA were performed in patients with amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS). NUEDEXTA has not been shown to be safe and effective in other types of emotional lability that can commonly occur, for example, in Alzheimer's disease and other dementias.
NUEDEXTA and certain other medicines can interact, causing serious side effects. If you take certain drugs or have certain heart problems, NUEDEXTA may not be right for you.
NUEDEXTA causes dose-dependent QTc prolongation. When initiating NUEDEXTA in patients at risk for QT prolongation and torsades de pointes, electrocardiographic (ECG) evaluation should be conducted at baseline and 3-4 hours after the first dose.
The most common adverse reactions are diarrhea, dizziness, cough, vomiting, asthenia, peripheral edema, urinary tract infection, influenza, increased gamma-glutamyltransferase, and flatulence. NUEDEXTA may cause dizziness.
These are not all the risks from use of NUEDEXTA. Please refer to full Prescribing Information at www.NUEDEXTA.com.
