• Acorda and Biogen Idec Agree to Fampridine-SR Ex-U.S. Collaboration on June 30, 2009
  • Upfront Payment of $110 Million; Potential Deal Value Over $500 Million
• Company Notified by U.S. Food and Drug Administration (FDA) that Advisory Committee Meeting Will be Held for Fampridine-SR

Acorda Therapeutics, Inc. (Nasdaq: ACOR) today announced its financial results for the second quarter of 2009.

“A very productive second quarter was highlighted by the completion of our ex-U.S. collaboration with Biogen Idec, which we believe could benefit people with MS as well as Acorda shareholders. Biogen Idec has the capabilities and expertise to maximize the value of Fampridine-SR in ex-US markets, if approved, and to make it available to patients around the world who can potentially benefit from it,” said Ron Cohen, M.D., Acorda Therapeutics’ President and CEO. “To continue to build shareholder value, in addition to advancing the Fampridine-SR program we are moving two of our preclinical product candidates towards INDs, and working to identify later stage product opportunities for potential acquisition.”

Financial Results and Product Update

Zanaflex Capsules^® (tizanidine hydrochloride) and Zanaflex^® (tizanidine hydrochloride) Tablets gross sales - For the quarter ended June 30, 2009, the Company reported combined gross sales of Zanaflex Capsules and Zanaflex tablets of $14.8 million, compared to combined gross sales of $13.1 million for the same quarter in 2008. Gross sales are recognized using a deferred revenue recognition model, meaning Zanaflex Capsules and Zanaflex tablet shipments to wholesalers are recorded as deferred revenue and only recognized as revenue when end-user prescriptions of Zanaflex Capsules and Zanaflex tablets are reported. A slight downward trend in prescriptions was observed over the first two quarters of 2009.

Zanaflex Capsules and Zanaflex Tablets shipments - Total Zanaflex Capsules and Zanaflex tablet shipments for the quarter ended June 30, 2009 were $16.6 million, compared to total shipments of $16.0 million for the same quarter in 2008.

Research and development expenses for the quarter ended June 30, 2009 were $7.9 million, including $0.9 million of share-based compensation, compared to $8.1 million including $0.6 million of share-based compensation for the same quarter in 2008. The decrease in research and development expenses for the quarter ended June 30, 2009 was primarily due to the conclusion of the second Phase 3 Fampridine-SR study in Q2 2008 offset by increased expenses related to the development of the Company’s preclinical pipeline products.

Sales, general and administrative expenses for the quarter ended June 30, 2009 were $23.9 million, including $2.1 million of share-based compensation, compared to $17.6 million including $1.8 million of share-based compensation for the same quarter in 2008. This increase in expenses was primarily due to increases in Fampridine-SR pre-launch activities and SG&A staff and compensation. Sales, general and administrative expenses are expected to increase in 2009 compared to 2008, primarily due to an increase in the Company’s expected pre-launch costs.

Collaboration accounting - For the quarter ended June 30, 2009, the Company recorded a license revenue receivable and deferred revenue of $110.0 million for the upfront payment due to Acorda from Biogen Idec for the collaboration agreement entered into on June 30, 2009, for the development and commercialization of Fampridine-SR in markets outside of the U.S. Also, as a result of this collaboration agreement, a payment of $7.7 million became payable by Acorda to Elan and was recorded as a cost of license revenue payable and deferred expense recorded in other assets. The license payment of $110.0 million was received from Biogen on July 1, 2009 and the payment of $7.7 million was made to Elan on July 7, 2009. Given the multiple components of the contract, the Company is assessing the accounting implications of these transactions.

The Company reported a net loss of $23.3 million for the quarter ended June 30, 2009, or $0.62 per diluted common share, compared to a net loss of $18.8 million, or $0.58 per basic and diluted common share, for the same quarter in 2008.

As of June 30, 2009 Acorda held cash, cash equivalents, and short-term investments of $212.4 million. The Company expects this balance, in addition to the net proceeds of $102.3 million from the Biogen collaboration agreement, will provide a year-end 2009 cash, cash equivalents and short-term investment balance in excess of $250 million.

Fampridine-SR Update

• Acorda and Biogen Idec announced an ex-U.S. collaboration to develop and commercialize Fampridine-SR on July 1. Under the terms of the agreement, Acorda received an upfront payment of $110 million and can receive additional payments of up to $400 million based on the successful achievement of future regulatory and sales milestones. Biogen Idec will make tiered, double-digit royalty payments to Acorda on ex-U.S. sales. Biogen will be responsible for all development and commercialization activities outside the U.S.
• The FDA accepted the Fampridine-SR NDA for filing on May 5, 2009 and assigned it Priority Review with a Prescription Drug User Fee Act (PDUFA) date of October 22, 2009.
• The FDA has notified the Company that a Peripheral and Central Nervous System Drugs Advisory Committee meeting will be held for Fampridine-SR. The date of the meeting will be posted in the Federal Register when finalized.
• Acorda received notification from the European Medicines Agency (EMEA) that Fampridine-SR is eligible to be submitted for a centralized filing, and also qualifies as a New Active Substance (NAS), which confers 10 years of market exclusivity if approved. The Company also disclosed the submission of an Intent to File letter to the EMEA on April 8, 2009.
• Data from Fampridine-SR extension studies have been accepted for a platform presentation at the 25^th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) on September 10. Data from the Fampridine-SR thorough QT study will also be presented at the meeting, being held September 9-12 in Dusseldorf, Germany.
• Data on the extension studies have also been accepted for presentation at the 13^th Congress of the European Federation of Neurological Societies (EFNS), being held September 12-15 in Florence, Italy.
• As of June 30, 2009, 177 subjects from MS-F202 had been enrolled in an extension trial and 84, or approximately 47 percent, remained active in the trial, with duration of treatment ranging from 3.39 to 5.32 years. As of the same date, 269 patients from MS-F203 had been enrolled in a separate extension study and 180 of these, or approximately 66.9 percent, remained active, with duration of treatment ranging from 1.08 to 3.59 years. Also, as of this same date, 214 patients from MS-F204 had been enrolled in a third extension study and 176, or approximately 82 percent, remained active, with duration of treatment ranging from 14.33 months to 22.43 months. The total exposure to Fampridine-SR in our MS studies to date, including both double-blind and open label studies, is approximately 1750 patient-years.
• To ensure consistency of reporting, adverse event terms were standardized across all studies. Below is an updated table of adverse events for the three key controlled MS studies, MS-F202, MS-F203 and MS-F204.

MS-F202, MS-F203 and MS-F204: Most Frequent (>5%) Adverse Events

Some of the percentages reported in earlier tables have changed, which in some cases affects their rank order. The only new AE that now reports at over 5% is MS relapse, at 5.3% for the Fampridine-SR treated group, vs. 3.8% for placebo. The imbalance between treatment groups for this event was due to worsening of MS symptoms occurring after discontinuation of drug.

Corporate Update

• Acorda supported a study by the North American Research Committee on Multiple Sclerosis (NARCOMS) that showed people with multiple sclerosis (MS) experience reduced income and earning potential as their mobility impairment increases. The data were presented at the American Academy of Neurology (AAN) 61^st Annual Meeting in April 2009.
