HAWTHORNE, N.Y.--(BUSINESS WIRE)--Feb. 16, 2012-- Acorda Therapeutics, Inc. (Nasdaq: ACOR) today announced its financial results for the fourth quarter and full year ended December 31, 2011.

“We were pleased with the commercial performance of AMPYRA in 2011, as well as by the advancement of our product pipeline during the year,” said Ron Cohen, M.D., Acorda Therapeutics’ President and CEO. “In 2012, we will focus on disciplined, strategic investment in these areas. We believe there is ample room to continue to grow AMPYRA within its current indication, and are supporting marketing initiatives to increase both consumer awareness and use in people with earlier stages of walking disability who can benefit from the drug. We also believe that there is significant potential for AMPYRA to be applied to other indications within MS and in new disease indications. Therefore, in 2012 our R&D spend is weighted toward studies assessing additional potential uses of AMPYRA in MS, as well as in cerebral palsy and chronic stroke.”

“In addition to AMPYRA, we have a robust pipeline of novel therapies that have either entered clinical development or are planned to do so in 2012. In all of our R&D efforts, we have designed studies to provide clear ‘go/no go’ signals that will enable us to make efficient decisions about investing in further development,” added Dr. Cohen. “ We are also excited about our agreement with Neuronex, Inc. to acquire a pre-NDA stage therapy in neurology, diazepam nasal spray,”

This press release includes financial results prepared in accordance with accounting principles generally accepted in the United States (GAAP), and also certain historical and forward-looking non-GAAP financial measures. In particular, Acorda has provided income (loss), adjusted to exclude share-based compensation charges, the net milestone revenue relating to Biogen Idec’s receipt of conditional approval from the European Commission for FAMPYRA in Q3 2011, the ZANAFLEX CAPSULES adjustments due to the Apotex patent infringement trial court decision in Q3 2011 and the upfront payment associated with in-licensing AC105 in Q2 2011. Also, Acorda has provided projected amounts of research and development (R&D) and sales, general, and administrative (SG&A) expenses excluding share-based compensation charges. These non-GAAP financial measures are not an alternative for financial measures prepared in accordance with GAAP. However, we believe the presentation of these non-GAAP financial measures when viewed in conjunction with our GAAP results, provide investors with a more meaningful understanding of our ongoing and projected operating performance because they exclude non-cash charges that are substantially dependent on changes in the market price of our common stock and expenses and income that do not arise from the ordinary course of our business. We believe these non-GAAP financial measures help indicate underlying trends in the company’s business and are important in comparing current results with prior period results and understanding projected operating performance. Also, management uses these non-GAAP financial measures to establish budgets and operational goals, and to manage the company’s business and to evaluate its performance. A reconciliation of the historical non-GAAP financial results presented in this release to our GAAP financial results is included in the attached financial statements.

Important Safety Information
AMPYRA can cause seizures; the risk of seizures increases with increasing AMPYRA doses. AMPYRA is contraindicated in patients with a prior history of seizure. Discontinue AMPYRA use if seizure occurs.

AMPYRA is contraindicated in patients with moderate or severe renal impairment (CrCl less-than or equal to 50 mL/min); the risk of seizures in patients with mild renal impairment (CrCl 51-80 mL/min) is unknown, but AMPYRA plasma levels in these patients may approach those seen at a dose of 15 mg twice daily, a dose that may be associated with an increased risk of seizures; estimated CrCl should be known before initiating treatment with AMPYRA.

AMPYRA should not be taken with other forms of 4-aminopyridine (4-AP, fampridine), since the active ingredient is the same.
Urinary tract infections were reported more frequently as adverse reactions in patients receiving AMPYRA 10 mg twice daily compared to placebo.

The most common adverse events (incidence greater-than or equal to 2% and at a rate greater than the placebo rate) for AMPYRA in MS patients were urinary tract infection, insomnia, dizziness, headache, nausea, asthenia, back pain, balance disorder, multiple sclerosis relapse, paresthesia, nasopharyngitis, constipation, dyspepsia, and pharyngolaryngeal pain.

About AMPYRA (dalfampridine)
AMPYRA is a potassium channel blocker approved as a treatment to improve walking in patients with multiple sclerosis (MS). This was demonstrated by an increase in walking speed. AMPYRA, which was previously referred to as Fampridine-SR, is an extended release tablet formulation of dalfampridine (4-aminopyridine, 4-AP), and is known as prolonged-, modified, or sustained-release fampridine (FAMPYRA^®) in some countries outside the United States (U.S).

In laboratory studies, dalfampridine extended release tablets has been found to improve impulse conduction in nerve fibers in which the insulating layer, called myelin, has been damaged. AMPYRA is being developed and commercialized in the U.S. by Acorda Therapeutics; FAMPYRA is being developed and commercialized by Biogen Idec in markets outside the U.S. based on a licensing agreement with Acorda.
