NEW DATA PRESENTED AT 64TH AAN ANNUAL MEETING HIGHLIGHTS BIOGEN IDEC’S COMMITMENT TO DELIVER PROMISING THERAPIES FOR UNMET NEEDS IN NEURODEGENERATIVE DISEASES
-- Biogen Idec Has Significant Presence at Leading Neurology Congress with 49 Platform and Poster Presentations --
Weston, Mass. – April 20, 2012 – Biogen Idec (NASDAQ: BIIB) will highlight its commitment to using novel science to address unmet medical needs in neurology at the upcoming 64th American Academy of Neurology (AAN) Annual Meeting. The meeting, held in New Orleans April 21-28, 2012, features 49 company-sponsored platform and poster presentations that demonstrate how, through focused research and development programs, Biogen Idec is pursuing treatments for neurological diseases with high unmet need.
In addition to presenting data from three marketed products in multiple sclerosis (MS) – TYSABRI® (natalizumab), AVONEX® (interferon beta-1a), and FAMPYRA® (prolonged-release fampridine tablets) – the company will present results from investigational trials of its late-stage pipeline, including: BG-12, PEGylated interferon beta-1a, and daclizumab high-yield process (DAC HYP) for MS; and dexpramipexole, a potential treatment for amyotrophic lateral sclerosis (ALS).
“We are committed to using novel science to tackle the unmet medical needs of those living with chronic and debilitating neurologic conditions,” said Douglas E. Williams, Ph.D., executive vice president, Research and Development at Biogen Idec. “Our focus on research and development of MS therapies has resulted in numerous product offerings and an extensive pipeline addressing the individual needs of many MS patients, both now and in the future. As we expand this expertise into other diseases areas such as ALS, we will continue to make progress toward addressing significant unmet medical needs in neurology.”
Key study results to be presented include:
Additional presentations include long-term data for AVONEX; data highlighting FAMPYRA, the first oral formulation indicated for the improvement of walking in adult MS patients with walking disability; and full data from the DAC HYP Phase 2b SELECT trial.
Notable data from Biogen Idec at AAN 2012:
PEGYLATED INTERFERON BETA-1A

TYSABRI is approved in more than 65 countries. TYSABRI is approved in the United States as a monotherapy for relapsing forms of MS, generally for patients who have had an inadequate response to, or are unable to tolerate, an alternative MS therapy. In the European Union, it is approved for highly active RRMS in adult patients who have failed to respond to beta interferon or have rapidly evolving, severe RRMS.
TYSABRI has advanced the treatment of MS patients with its established efficacy. Data from the Phase 3 AFFIRM trial, which was published in the New England Journal of Medicine, showed that after two years, TYSABRI treatment led to a 68 percent relative reduction (p<0.001) in the annualized relapse rate when compared with placebo and reduced the relative risk of disability progression by 42-54 percent (p<0.001).
TYSABRI increases the risk of progressive multifocal leukoencephalopathy (PML), an opportunistic viral infection of the brain which usually leads to death or severe disability. Infection by the JC virus (JCV) is required for the development of PML and patients who are anti-JCV antibody positive have a higher risk of developing PML. Factors that increase the risk of PML are presence of anti-JCV antibodies, prior immunosuppressant use, and longer TYSABRI treatment duration. Patients who have all three risk factors have the highest risk of developing PML. Other serious adverse events that have occurred in TYSABRI-treated patients include hypersensitivity reactions (e.g., anaphylaxis) and infections, including opportunistic and other atypical infections. Clinically significant liver injury has also been reported in the post-marketing setting. A list of adverse events can be found in the full TYSABRI product labeling for each country where it is approved.
TYSABRI is marketed and distributed by Biogen Idec Inc. and Elan Corporation, plc. For full prescribing information and more information about TYSABRI, please visit www.biogenidec.com or www.elan.com.
AVONEX is one of the most prescribed treatments for relapsing forms of MS worldwide. It has been approved for use in the United States and European Union for more than 15 years. AVONEX is indicated for the treatment of patients with relapsing forms of MS to slow the accumulation of physical disability and decrease the frequency of clinical exacerbations. Patients with MS in whom efficacy has been demonstrated include patients who have experienced a first clinical episode and have MRI features consistent with MS.
AVONEX should be used with caution in patients with depression or other mood disorders and in patients with seizure disorders. AVONEX should not be used by pregnant women. Patients should also be monitored for signs of hepatic injury. Rare cases of anaphylaxis have been reported. Patients with cardiac disease should be closely monitored. Routine periodic blood chemistry and hematology tests are recommended during treatment with AVONEX.
The most common side effects associated with AVONEX treatment are flu-like symptoms, including chills, fever, myalgia, and asthenia.
FAMPYRA is a prolonged-release (sustained release) tablet formulation of the drug fampridine (4-aminopyridine, 4-AP or dalfampridine). FAMPYRA has been developed to improve walking in adult patients with MS. In MS, damaged myelin exposes channels in the membrane of axons allowing potassium ions to leak, weakening the electrical current sent through nerves. Studies have shown that fampridine can increase conduction along damaged nerves, which may result in improved walking ability. This prolonged-release formulation was developed and is being commercialized in the United States by Acorda Therapeutics, Inc. (NASDAQ: ACOR) under the trade name AMPYRA® (dalfampridine) Extended Release Tablets, 10 mg. Biogen Idec licensed rights from Acorda to develop and commercialize fampridine in all markets outside the United States.
BG-12 (dimethyl fumarate) is an investigational oral therapy for which two large pivotal Phase 3 clinical studies for the treatment of RRMS, the most common form of MS, have been completed. Biogen Idec has recently filed regulatory submissions for BG-12 in the United States and European Union. BG-12 is the only currently known investigational compound for the treatment of RRMS that has experimentally demonstrated activation of the Nrf-2 pathway. In 2011, Biogen Idec announced positive data from DEFINE and CONFIRM, two global, placebo-controlled Phase 3 clinical trials that evaluated 240 mg of BG-12, administered either twice a day or three times a day, for two years.
About Daclizumab High-Yield Process
Daclizumab high-yield process (DAC HYP) is a subcutaneous formulation of daclizumab in late-stage clinical development for the treatment of RRMS, the most common form of MS. DAC HYP is a humanized monoclonal antibody that binds to CD25, a receptor subunit that is expressed at high levels on T-cells that are thought to become abnormally activated in autoimmune conditions such as MS. Data from previous clinical trials showed that DAC HYP increases CD56bright Natural Killer cells, which target the activated immune cells that can play a key role in MS without causing general immune cell depletion. DAC HYP is currently being studied in the DECIDE Phase 3 clinical trial, which is evaluating the efficacy and safety of once-monthly subcutaneous DAC HYP as a monotherapy compared to interferon beta 1-a therapy.
About PEGylated Interferon Beta-1a
PEGylated interferon beta-1a is currently under investigation in a Phase 3 clinical trial for the treatment of relapsing MS. PEGylated interferon beta-1a, administered via subcutaneous injection, is being evaluated for its ability to last longer in a patient's system, potentially leading to an MS treatment that would require fewer injections.
Dexpramipexole is a novel, orally administered compound under development for the treatment of ALS. It has shown neuroprotective properties in both in vitro assays and in vivo ALS models. In a Phase 2 study, dexpramipexole achieved its primary objective evaluating safety and tolerability and also showed a trend toward dose-related slowing of functional decline and a trend toward extending survival at the highest dose (150 mg twice daily). Dexpramipexole has been granted Fast Track status by the U.S. Food and Drug Administration (FDA), which may result in an expedited review, and has received orphan drug designation for the treatment of ALS from both the FDA and the European Medicines Agency. Biogen Idec and Knopp Neurosciences have an exclusive, worldwide license agreement for dexpramipexole.
