WESTON, Mass.--(BUSINESS WIRE)--Biogen Idec (NASDAQ: BIIB) will present 58 data sets from the company’s multiple sclerosis (MS) clinical portfolio of approved and investigational products at the 29th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) in Copenhagen, Denmark, October 2-5.

The collection of data being presented at ECTRIMS represents Biogen Idec’s industry-leading expertise in MS research and showcases the company’s deep understanding of differing patient needs. Through decades of cutting-edge science, Biogen Idec has more experience than any other company in advancing the treatment of this disease, recognising that physicians need therapeutic choices to meet treatment goals.

“Biogen Idec is proud to be at the forefront of innovation in MS, which has been made possible through our research and development efforts over the past 30 years,” said Douglas E. Williams, Ph.D., executive vice president, Research and Development at Biogen Idec. “Our commitment has enabled us to bring a number of therapy options to patients, and we are excited to be presenting data on some promising candidates which have the potential to broaden the treatment spectrum for people living with this chronic, debilitating disease.”

Data at ECTRIMS will be presented from across Biogen Idec’s portfolio, including:

Approved medicines:

TYSABRI® (natalizumab): offers established efficacy that has been proven to reduce relapses and slow disability progression.

TECFIDERA® (dimethyl fumarate): an oral treatment for relapsing forms of MS, including relapsing-remitting MS (RRMS), which has been clinically proven to significantly reduce important measures of disease activity with a favorable safety/tolerability profile. TECFIDERA is currently approved in the United States, Canada and Australia.

FAMPYRA® (prolonged-release fampridine tablets): the first approved treatment to address the unmet medical need of walking improvement in MS patients, demonstrating efficacy in patients with all MS types. Approved in the European Union.

Investigational medicines:

PLEGRIDYTM (pegylated interferon beta-1a): a potential new molecular entity for relapsing forms of MS in which interferon beta-1a is pegylated to extend its half-life and prolong its exposure in the body. Pegylation offers a less-frequent dosing schedule.

DACLIZUMAB HIGH-YIELD PROCESS (DAC HYP): is being developed as a once-monthly subcutaneous injection. DAC HYP is believed to target the activated immune cells that can play a key role in MS without causing general immune cell depletion. DAC HYP is being developed under a collaboration agreement with AbbVie, Inc.

Anti-LINGO-1 (BIIB033): is the first candidate being investigated for its potential to repair neurons damaged by MS.

Registry Research Fellowship Program opening for applications

At ECTRIMS, Biogen Idec will also launch The Multiple Sclerosis Registry Research Fellowship Program, an initiative which solidifies our ongoing commitment to clinical research in order to improve the lives of people living with MS. Grants awarded through the program will provide an annual stipend of up to €75,000 per fellow, for training in research with large real-world evidence datasets in MS.

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 due to the risk of progressive multifocal leukoencephalopathy (PML). In the European Union, it is approved for highly active relapsing-remitting MS (RRMS) in adult patients who have failed to respond to beta interferon or glatiramer acetate 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 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.

As a result of the acquisition from Elan, TYSABRI will be marketed and distributed solely by Biogen Idec. For full prescribing information and more information about TYSABRI, please visit www.biogenidec.com.


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. In clinical trial, the highest incidence of adverse reactions identified with FAMPYRA given at the recommended dose was urinary tract infection, although infection was often not proven by culture. Other adverse drug reactions identified were mainly divided between neurological disorders, such as insomnia, balance disorder, dizziness, paraesthesia, headache and gastrointestinal disorders including nausea, dyspepsia and constipation. In post-marketing experience, there have been reports of seizure. Confounding factors may have contributed to the occurrence of seizure in some patients.

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.

TECFIDERA is an oral therapy for relapsing forms of MS, including relapsing-remitting MS, the most common form of MS. TECFIDERA is currently approved in the United States, Canada and Australia, and is under review by regulatory authorities in the European Union.

TECFIDERA has been proven to reduce MS relapses, progression of disability and MS brain lesions, while demonstrating a favourable safety and tolerability profile. In clinical trials, the most common adverse events associated with TECFIDERA were flushing and gastrointestinal (GI) events. Other side effects included a decrease in mean lymphocyte counts during the first year of treatment, which then plateaued. The efficacy and safety of TECFIDERA has been studied in a large, global clinical program with more than 3,600 MS patients, which includes an ongoing long-term extension study. It is believed that TECFIDERA provides a new approach to treating MS by activating the Nrf2 pathway, although its exact mechanism of action is unknown. This pathway provides a way for cells in the body to defend themselves against inflammation and oxidative stress caused by conditions like MS.

PLEGRIDY is a new molecular entity in which interferon beta-1a is pegylated to extend its half-life and prolong its exposure in the body. PLEGRIDY is a member of the interferon class of treatments, which is often used as a first-line treatment for MS.

Regulatory authorities in the US and the EU accepted the marketing applications for the review of PLEGRIDY in relapsing forms of MS in July 2013.

About Daclizumab High-Yield Process

Daclizumab high-yield process (DAC HYP) is 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 (NK) 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-1a therapy.

Biogen Idec is developing DAC HYP in collaboration with AbbVie, Inc.
