Study presented at the 30th International Epilepsy Congress also showed pharmacokinetic and safety profile consistent with previous studies in healthy volunteers
ARDSLEY, NY, USA I June 26, 2013 I Acorda Therapeutics, Inc. (Nasdaq: ACOR) today announced results of the first clinical study to assess pharmacokinetics, safety and tolerability of Diazepam Nasal Spray in people with epilepsy. Study findings were presented on June 25 at the biennial International Congress of the International League Against Epilepsy (ILAE) and International Bureau for Epilepsy (IBE), being held in Montreal, Canada. Diazepam Nasal Spray is being developed for the treatment of people with epilepsy who experience cluster seizures, also known as acute repetitive seizures.
“Diazepam Nasal Spray offers a therapeutic alternative that can be administered rapidly and conveniently.”
“The study results showed that the Diazepam Nasal Spray pharmacokinetics are comparable whether it is administered during or immediately following a seizure. For people with epilepsy who experience cluster seizures, it is critical that treatment be administered as soon as a cluster is recognized, to prevent additional seizure activity,” said Enrique Carrazana, M.D., Acorda’s Chief Medical Officer. “Diazepam Nasal Spray offers a therapeutic alternative that can be administered rapidly and conveniently.”
The study was an open-label, multi-center clinical trial, comprising 31 people with epilepsy who were admitted to epilepsy monitoring units. Each received a single dose of diazepam, administered as one spray in each nostril, during or immediately following a seizure. Blood levels of diazepam were measured serially for a period of up to 12 hours following the dose.
Results showed that diazepam was well absorbed from the nasal cavity of people with epilepsy, had a similar pharmacokinetic profile regardless of when administered relative to the seizure episode and was well tolerated. The most common adverse events were related to the nasal route of delivery; most adverse events were mild and transient, and resolved within a day. Most common among these were an altered sense of taste and nasal discomfort, experienced by 26% and 23% of study subjects respectively. The overall safety and tolerability of Diazepam Nasal Spray in this study was consistent with the established safety profile of diazepam products.
Acorda also presented the results of a separate study showing that Diazepam Nasal Spray and an equivalent dose of the rectal gel formulation of diazepam had comparable bioavailability in healthy volunteers. These data were previously presented at the 65th American Academy of Neurology Annual Meeting in March, 2013.
Acorda plans to submit a 505(b)(2)-type New Drug Application (NDA) for Diazepam Nasal Spray to the U.S. Food and Drug Administration (FDA) in 2013 and rely upon FDA’s previous findings of safety and efficacy for diazepam rectal gel.
About Epilepsy and Cluster Seizures/Acute Repetitive Seizures
Epilepsy is a neurological condition that produces seizures affecting a variety of mental and physical functions. Seizures are symptoms of abnormal brain activity, and occur when a brief, strong surge of electrical activity affects part or all of the brain.
The Centers for Disease Control and Prevention (CDC) estimates that approximately 2.3 million adult Americans have active epilepsy. Cluster seizures, also known as acute repetitive seizures, are characterized by recognizable, recurring episodes of seizure clusters. In the U.S., there are up to 175,000 people with epilepsy who experience cluster seizures despite being on stable regimens of antiepileptic drugs (AEDs).
About Acorda Therapeutics
Acorda Therapeutics is a biotechnology company focused on developing therapies that restore function and improve the lives of people with MS, spinal cord injury and other neurological conditions.
Acorda markets AMPYRA® (dalfampridine) Extended Release Tablets, 10 mg, in the United States as a treatment to improve walking in patients with multiple sclerosis (MS). This was demonstrated by an improvement in walking speed. AMPYRA is marketed outside the United States as FAMPYRA® (prolonged-release fampridine tablets) by Biogen Idec under a licensing agreement from Acorda. AMPYRA and FAMPYRA are manufactured under license from Alkermes Pharma Ireland Limited.
The Company also markets ZANAFLEX CAPSULES® (tizanidine hydrochloride) and Zanaflex tablets, a short-acting drug for the management of spasticity. Acorda also receives sales royalties on tizanidine hydrochloride capsules, an authorized generic version of ZANAFLEX CAPSULES, distributed by Actavis, Inc. under its agreement with Acorda.
Acorda has one of the leading pipelines in the industry of novel neurological therapies. The Company is developing Diazepam Nasal Spray for treatment of certain epileptic seizures. It is also studying AMPYRA to improve a range of functional impairments caused by MS, as well as its potential for use in other neurological conditions, including cerebral palsy and post-stroke deficits. In addition, Acorda is developing clinical stage compounds AC105 for acute treatment of spinal cord injury, GGF2 for treatment of heart failure and rHIgM22, a remyelinating monoclonal antibody, for the treatment of MS. GGF2 is also being investigated in preclinical studies as a treatment for neurological conditions such as stroke and peripheral nerve damage. Chondroitinase, an enzyme that encourages nerve plasticity in spinal cord injury, is in preclinical development.
