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 65 th 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.
