Biogen Idec and Elan Provide Update on Utilization and Safety of TYSABRI(R) in Patients with Multiple SclerosisCAMBRIDGE, Mass. & DUBLIN--(HSMN NewsFeed)--Biogen Idec (NASDAQ: BIIB ) and Elan Corporation, plc (NYSE: ELN ) today announced new data on the global utilization and safety of TYSABRIŽ (natalizumab), citing that as of the end of September 2007 approximately 17,000 patients are on commercial and clinical therapy worldwide, and that the safety data to date continue to support a favorable benefit-risk profile for TYSABRI. These data will be presented as part of the companies' symposia being held on Friday, October 12, 2007 at 6 p.m. CEST at the 23rd Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) in Prague, Czech Republic.
As of the end of September 2007:
- In the US, approximately 10,500 patients are on TYSABRI commercially and over 2,100 physicians have prescribed the therapy;
- In the EU, approximately 5,500 patients are on TYSABRI therapy commercially; and
- In global clinical trials, approximately 1,000 patients are on TYSABRI therapy.
According to data available to the companies as of mid-September 2007, there have been no new reports of confirmed cases of progressive multifocal leukoencephalopathy (PML). The safety data to date continue to support a favorable benefit-risk profile for TYSABRI. The companies plan to continue to provide similar updates at future medical meetings.
"Neurologists and patients are increasingly choosing TYSABRI given its significant impact on clinically meaningful and relevant endpoints, including relapses and disability progression. Ultimately, we believe the full potential of TYSABRI will be realized, making it the leading MS therapy," said Michael Panzara, MD, MPH, Vice President and Chief Medical Officer, Neurology Strategic Business Unit, Biogen Idec.
"Continued patient experience and ongoing clinical research will further differentiate TYSABRI as a valuable treatment option for MS patients around the world. TYSABRI is currently approved in more than 20 countries, and we hope to offer this therapeutic alternative to more patients in the future," said Gordon Francis, MD, Senior Vice President, Global Clinical Development, Elan.
About TOUCH and TYGRIS
Before initiating treatment, all US patients, prescribers and infusion sites must be enrolled in the TOUCH Prescribing Program (TYSABRI Outreach: Unified Commitment to Health). TOUCH is designed to determine the incidence of and risk factors for serious opportunistic infections (OIs), including PML, and to monitor patients for signs and symptoms of PML while promoting informed benefit-risk discussions prior to initiating TYSABRI treatment. Physicians report on PML, serious OIs, deaths and discontinuation of therapy on an ongoing basis.
TYGRIS (TYSABRI Global ObseRvation Program In Safety) is expected to enroll 5,000 patients worldwide, including approximately 3,000 patients from TOUCH. Patients in TYGRIS are evaluated at baseline and every six months thereafter for five years. Researchers will evaluate data including medical/MS history; prior TYSABRI use; prior use of immunomodulatory, antineoplastic, or immunosuppressive agents; and all serious adverse events, including PML and other serious OIs, and malignancies.
Adverse event reporting in the post-marketing setting is voluntary. It is possible that not all reactions have been reported, or that some reactions are not reported to Biogen Idec or Elan in a timely manner.
TYSABRI is a treatment approved for relapsing forms of MS in the United States and relapsing-remitting MS in the European Union. According to data that have been published in the New England Journal of Medicine, after two years, TYSABRI treatment led to a 68% relative reduction (p<0.001) in the annualized relapse rate compared to placebo and reduced the relative risk of disability progression by 42-54% (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. Other serious adverse events that have occurred in TYSABRI-treated patients included hypersensitivity reactions (e.g., anaphylaxis) and infections. Serious opportunistic and other atypical infections have been observed in TYSABRI-treated patients, some of whom were receiving concurrent immunosuppressants. Herpes infections were slightly more common in patients treated with TYSABRI. In MS trials, the incidence and rate of other serious and common adverse events, including the overall incidence and rate of infections, were balanced between treatment groups. Common adverse events reported in TYSABRI-treated patients include headache, fatigue, infusion reactions, urinary tract infections, joint and limb pain, and rash.
In addition to the United States and European Union, TYSABRI is also approved in Switzerland, Canada, Australia, New Zealand and Israel. TYSABRI was discovered by Elan and is co-developed with Biogen Idec.
