Biogen Idec Receives Negative Opinion from the CHMP on FAMPYRA

January 21, 2011 Neurodegenerative Diseases

The Company intends to appeal the negative CHMP opinion


ZUG, Switzerland--(BUSINESS WIRE)--Biogen Idec (NASDAQ: BIIB) announced today that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has issued a negative opinion recommending against approval of FAMPYRA® (prolonged-release fampridine 10 mg tablets) to improve walking ability in adult patients with multiple sclerosis (MS) in the European Union. Biogen Idec intends to appeal this opinion and request a re-examination of the decision by the CHMP.

“About two-thirds of MS patients report difficulty in walking due to their disease1,2, and currently there is no therapy approved in Europe to address this high unmet medical need,” said Alfred Sandrock, M.D., Ph.D., Head of Neurology Research & Development at Biogen Idec. “Tens of thousands of people with MS have already received the therapy in the United States, where it is approved, and many have reported important benefits. We will work closely with the CHMP during the appeal process to address the Committee’s concerns, with the goal of making this important medication available to MS patients in Europe.”

As a leader in MS with two MS medications on the market and six potential MS therapies in the pipeline, Biogen Idec has significant scientific expertise in MS and is committed to improving the lives of patients living with this disease.

As of the end of September 2010, approximately 6300 prescribers had initiated approximately 31,000 MS patients on prolonged-release fampridine tablets treatment in the United States (U.S.), where the drug is commercialized by its developer, Acorda Therapeutics, Inc., under the trade name AMPYRA® (dalfampridine) Extended Release Tablets, 10 mg. AMPYRA was approved by the U.S. Food and Drug Administration on January 22, 2010.

For further details about the CHMP opinion on FAMPYRA, please visit the EMA website www.ema.europa.eu/ema.


FAMPYRA 10 mg tablets is a prolonged-release (sustained release) tablet formulation of the drug fampridine (4-aminopyridine or 4-AP). FAMPYRA has been developed to improve walking in adult patients with multiple sclerosis (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 FAMPYRA 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.

In two Phase III clinical trials, a significantly greater portion (p<0.001) of patients treated with FAMPYRA had a consistent improvement in walking speed when compared to placebo (34.8 percent vs. 8.3 percent and 42.9 percent vs. 9.3 percent, respectively). The increased response rate in the FAMPYRA group was observed across all types of MS included in the studies.

The FAMPYRA-treated patients who had consistent improvement in the two studies experienced an average increase in walking speed of 25.2 percent and 24.7 percent compared to 4.7 percent and 7.7 percent, respectively, for the entire placebo group.

The majority of the study participants in these trials were using immunomodulatory drugs, including interferons, glatiramer acetate, and natalizumab; however the magnitude of improvement in walking ability was independent of concomitant therapy.

Patients confirmed the clinical meaningfulness of improved walking using the 12-item Multiple Sclerosis Walking Scale (MSWS-12), a patient-based assessment that measures the impact of walking impairment on the patient’s ability to perform everyday activities.
