Cepheid Market Reach Extended with Licenses in Canada and Registrations in Mexico

SUNNYVALE, Calif., June 3 /PRNewswire-FirstCall/ -- Cepheid (Nasdaq: CPHD) today announced that Health Canada issued a medical device license for Xpert(TM) GBS, for the rapid detection of Group B Streptococcus (GBS), and Xpert(TM) EV (enterovirus), for the rapid detection of EV-associated meningitis. These tests join Xpert MRSA, which received Health Canada license in January of this year. In Mexico, Cepheid has received registration from the Secretary of Health for its GeneXpert System and Xpert(TM) MRSA, Xpert GBS and Xpert EV tests. The products will be distributed exclusively through I.L. Diagnostics S.A. in Mexico and Fisher Scientific in Canada.

"Regulatory licenses and registrations are critical in our efforts to effectively penetrate these new markets," said Rob Koska, Cepheid's Senior Vice President, Worldwide Commercial Operations. "Both Canada and Mexico will now have access to all of these high medical value-added diagnostic products that are improving patient care throughout the world."

As is the situation in the United States, MRSA is a growing public health concern in Mexico. According to a study published in the Journal of Clinical Microbiology, "The prevalence of resistant bacteria has been increasing rapidly in Mexican hospitals during the last few years. According to different studies performed in the 1980s, 1990s, and 2000, the prevalence of MRSA in Mexican hospitals was estimated to vary from 7 to 30%." Rapid MRSA test results continue to be the cornerstone of the world's most effective surveillance programs.

GBS is a common cause of life-threatening infection in newborns worldwide. According to the Centers for Disease Control (CDC), there are still over 1500 annual cases of early onset GBS in the U.S. -- despite current testing guidelines which recommend screening between 35 and 37 weeks of gestation. However, this does not protect against the bacterial population changing in the weeks preceding delivery, nor does it help women who go into pre-term labor. Xpert GBS is uniquely positioned to yield test results in about an hour, where standard culture-based testing may take several days. The Xpert GBS test allows doctors to make a prompt treatment decision, making it an extremely useful tool in the intrapartum period preceding delivery.

Enterovirus, the cause of viral meningitis, is not a life-threatening disease and typically self-resolves in less than 10 days. However, bacterial meningitis (caused by a bacterial infection) is potentially fatal. As patients present with meningitis symptoms, the need for a test to differentiate between the two conditions is critical. Traditional tests take days to provide results, whereas the Xpert EV test can provide physicians with results in about two and a half hours. With rapid EV results, physicians are able to make better patient management and treatment decisions.
