>> TYSABRI-R- Two-Year Monotherapy Trial Demonstrates Significant Impact on Disability Progression and Relapse Rate in Multiple Sclerosis
CAMBRIDGE, Mass. & DUBLIN, Ireland--(BUSINESS WIRE)--Feb. 17, 2005-- Data Show 42% Reduction in the Risk of Disability Progression and Sustained 67% Reduction in Relapse Rate
Biogen Idec (NASDAQ: BIIB - News) and Elan Corporation, plc (NYSE: ELN - News) announced today that the Phase III TYSABRI® (natalizumab) AFFIRM monotherapy trial achieved the two-year primary endpoint of slowing the progression of disability in patients with relapsing forms of multiple sclerosis (MS). TYSABRI treatment led to a 42 percent reduction in the risk of disability progression relative to placebo. These data also demonstrated a 67 percent reduction in the rate of clinical relapses over two years, which was sustained and consistent with the previously reported one-year results.
Other data from AFFIRM at two years, including MRI measures and immunogenicity were similar to previously reported results.
The adverse event profile at two years was also consistent with previously reported results. Common events included headache, fatigue, urinary tract infection, depression, lower respiratory tract infection, limb and joint pain, and pharyngitis. The incidence of infections in TYSABRI-treated and placebo-treated patients was similar. Serious infections occurred in 3.2 percent and 2.6 percent of patients, respectively. These included bacterial infections such as pneumonia and urinary tract infection, which responded appropriately to antibiotics. TYSABRI has also been associated with hypersensitivity reactions, including serious systemic reactions that occurred at an incidence of less than 1 percent of patients.
"TYSABRI, with its significant effect on slowing the progression of disability, offers new hope for patients with MS," said Burt Adelman, MD, executive vice president, Development, Biogen Idec. "With these data, we gain a more complete understanding of the broad therapeutic benefit of TYSABRI in MS."
"Results from the two-year monotherapy clinical trial mark a major milestone in the treatment of MS. These two-year data strengthen our belief that TYSABRI will become the leading therapy for MS patients," said Lars Ekman, MD, executive vice president and president, Research and Development, Elan.
AFFIRM is a two-year, randomized, multi-center, placebo-controlled, double-blind study of 942 patients conducted in 99 sites worldwide, evaluating the effect of TYSABRI on the progression of disability as measured by the Expanded Disability Status Scale (EDSS) and the rate of clinical relapses. Patients were randomized to receive either a 300 mg IV infusion dose of TYSABRI (n=627) or placebo (n=315) every four weeks.
Based on one-year data from AFFIRM and the SENTINEL add-on trial with AVONEX® (Interferon beta-1a), the U.S. Food and Drug Administration (FDA) granted Accelerated Approval for TYSABRI on November 23, 2004, as a treatment for relapsing forms of MS.
The companies anticipate that two-year data from the AFFIRM trial will be presented at the American Academy of Neurology (AAN) meeting in April 2005. The companies expect two-year results from the SENTINEL trial will be available mid-year. Two-year data from both studies will also be submitted to regulatory authorities.
About TYSABRI
TYSABRI, the first humanized monoclonal antibody approved for the treatment of MS, inhibits adhesion molecules on the surface of immune cells. Research suggests TYSABRI works by preventing immune cells from migrating from the bloodstream into the brain where they can cause inflammation and potentially damage nerve fibers and their insulation.
Biogen Idec and Elan are collaborating equally on the development of TYSABRI in MS, Crohn's disease (CD), and rheumatoid arthritis (RA). Regulatory authorities in Canada and Australia have designated TYSABRI for Priority Review as a treatment for MS, and the European Medicines Agency (EMEA) is actively reviewing the application.
In September 2004, the companies submitted a Marketing Authorisation Application (MAA) to the EMEA for CD based on Phase III studies. Another Phase III induction trial for CD is ongoing. A Phase II trial is also underway to evaluate TYSABRI in RA. To date, more than 3,200 patients have received TYSABRI in clinical trials. <<
