Acorda made an initial option payment of $2.0 million to Neuronex in the first quarter of 2012, and provided $1.5 million in ensuing quarters to support certain research and development activities conducted by Neuronex prior to completing the acquisition.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. A 505(b)(2) application allows for an NDA that relies on medical literature and FDA’s finding of safety and effectiveness for a previously approved drug product. About Epilepsy and Acute Repetitive Seizures (ARS) 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 Americans have active epilepsy. Acute repetitive seizures (ARS) are characterized by recognizable, recurring episodes of seizure clusters. 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 Watson Pharmaceutics, Inc. under its agreement with Acorda. Acorda has an industry-leading pipeline 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 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 and GGF2 for treatment of heart failure. GGF2 is also being investigated in preclinical studies as a treatment for neurological conditions such as stroke and spinal cord injury. Additional development programs include rHIgM22, a remyelinating monoclonal antibody for the treatment of MS, and chondroitinase, an enzyme that encourages nerve plasticity in spinal cord injury.
