April 11, 2011 Neurodegenerative Diseases

-- Company Continues to Redefine the Future of Multiple Sclerosis Treatment --

 

WESTON, Mass.--(BUSINESS WIRE)--Biogen Idec (NASDAQ: BIIB) today announced that data highlighting the company’s focus and drive towards addressing the needs of people living with multiple sclerosis (MS) will be presented at the American Academy of Neurology’s (AAN) 63rd Annual Meeting in Honolulu, April 9-16, 2011. Fifty-five company-sponsored platform and poster presentations featuring data focusing on the company’s innovation and research in the treatment and management of the disease will be presented during the Congress. Highlights will include data on Biogen Idec’s currently marketed products, TYSABRI® (natalizumab) and AVONEX® (interferon beta-1a), as well as four late-stage programs: FAMPYRA® (prolonged-release fampridine tablets), the oral disease-modifying therapy BG-12 (dimethyl fumarate), PEGylated interferon beta-1a and daclizumab.

“The data being presented at AAN illustrate the breadth of Biogen Idec’s ongoing commitment to the MS community,” said Douglas E. Williams, Ph.D., executive vice president, research and development at Biogen Idec. “MS affects each person differently and, until we find a cure, Biogen Idec is dedicated to driving ground-breaking research and pursuing highly differentiated therapies. Our leading marketed products, TYSABRI and AVONEX continue to remain gold-standards of care in the treatment and management of MS. Our robust pipeline has the potential to offer effective and convenient therapies targeting the different pathways of the disease, addressing the unique needs of each individual MS patient.”

The following represents select data highlights during the meeting from the Company’s portfolio of marketed products.

About TYSABRI

TYSABRI is approved in more than 45 countries. In the U.S., it is approved for relapsing forms of multiple sclerosis (MS) and in the European Union for relapsing-remitting MS (RRMS).

TYSABRI has advanced the treatment of MS patients with its established efficacy. It has been proven to reduce flare-ups and slow physical disability progression. 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 that usually leads to death or severe disability.

The risk of PML increases with longer treatment duration and in patients treated with an immunosuppressant prior to receiving TYSABRI. 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 patients treated with TYSABRI in the post-marketing setting. Common adverse events reported in TYSABRI-treated MS patients include headache, fatigue, infusion reactions, urinary tract infections, joint and limb pain, and rash. TYSABRI is co-marketed by Biogen Idec Inc. and Elan Corporation, plc. For more information about TYSABRI, please visit www.tysabri.com, www.biogenidec.com or www.elan.com, or call 1-800-456-2255.

About AVONEX

AVONEX is one of the most prescribed treatments for relapsing forms of MS worldwide. It is used worldwide as a treatment for relapsing forms of MS to slow the progression of physical disability and reduce relapses. AVONEX is also approved for patients who have their first clinical MS attack and have a brain MRI scan consistent with MS.

The most common side effects associated with AVONEX MS treatment are flu-like symptoms, including myalgia, fever, fatigue, headache, chills, nausea, vomiting, pain and asthenia.

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 with cardiac disease should be closely monitored. Patients should also be monitored for signs of hepatic injury. Routine periodic blood chemistry and hematology tests are recommended during treatment with AVONEX. Rare cases of anaphylaxis have been reported. Please see complete prescribing information available at www.AVONEX.com.

About FAMPYRA

FAMPYRA 10 mg tablets is a prolonged-release (sustained release) tablet formulation of the drug fampridine (4-aminopyridine 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 U.S. by Acorda Therapeutics, Inc. It has been approved in the U.S. under the trade name AMPYRA® (dalfampridine) Extended Release Tablets, 10 mg. Biogen Idec plans to commercialize and further develop the product outside of the U.S. under a licensing agreement with Acorda.

About BG-12

BG-12 (dimethyl fumarate) is an investigational oral therapy in clinical development for the treatment of RRMS, the most common form of MS. BG-12 is currently being evaluated as a monotherapy in two Phase 3 clinical trials, DEFINE and CONFIRM, and in combination with commonly used first-line treatments in the Phase 2 EXPLORE trial.

Top-line results from the DEFINE study showed that 240 mg of BG-12, administered either twice or three times a day, demonstrated a highly statistically significant reduction (p<0.0001) in the proportion of patients with RRMS who relapsed at two years compared with placebo. Both doses of BG-12 also demonstrated a statistically significant reduction in annualized relapse rate, in the number of new or newly enlarging T2 hyperintense lesions, in new gadolinium-enhancing lesions, and in the rate of disability progression as measured by the Expanded Disability Severity Scale at two years. Initial data from the trial also showed that BG-12 demonstrated a favorable safety and tolerability profile.

BG-12 received Fast Track designation in MS from the U.S. Food and Drug Administration (FDA) in 2008. Biogen Idec retains full worldwide commercial rights to BG-12.

About PEGylated Interferon Beta-1a

PEGylated interferon beta-1a is under investigation for the treatment of relapsing MS and is currently enrolling a Phase 3 clinical trial. 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. Patients interested in learning more about the ADVANCE trial may speak with their physician or email ADVANCEstudy@biogenidec.com.

About Daclizumab

Daclizumab is a humanized monoclonal antibody that binds to the CD25 alpha subunit of the high affinity IL-2 receptor. CD25 is expressed at low levels on resting T-cells (immune cells) and at high levels on T-cells that can become activated in response to autoimmune conditions such as MS. Daclizumab is believed to work by selectively binding to and inhibiting this receptor on activated T-cells without causing T-cell depletion. Daclizumab is an investigational agent in clinical development for the treatment of MS in collaboration between Abbott and Biogen Idec. Daclizumab is currently being studied in two registrational clinical trials in patients with MS. Patients interested in learning more about the DECIDE trial may speak with their physician or email DECIDEstudy@biogenidec.com.
