FDA clears single test for 12 respiratory viruses

Editor's note: This story was revised Jan 8 to correct information about the location of the test's manufacturer.

Jan 7, 2008 (CIDRAP News) – A single test that can identify up to 12 different respiratory viruses, including three kinds of influenza, from one sample has won the Food and Drug Administration's (FDA's) approval.

The test, called the xTAG Respiratory Viral Panel (RVP), is the first that can detect and distinguish influenza A subtypes H1 and H3 and also detect influenza B, the FDA said in announcing the approval on Jan 3. Influenza A is the most severe type of flu in humans and has been the cause of pandemics, the agency noted.

The new test panel is also the first test for human metapneumovirus (hMPV), which was first identified in 2001, the FDA said.

The test is made by Toronto-based Luminex Molecular Diagnostics, part of Luminex Corp, headquartered in Austin, Tex. In a news release, the company called the xTAG RVP "a ground breaking test that, with a single patient sample, can assess the presence or absence of 12 viral targets and provide qualitative results in a few hours."

Conventional testing for the same viruses requires a number of separate tests and can take several days, the company said. The new product will help physicians provide appropriate treatment and prevent inappropriate antibiotic use that has helped spawn resistant microbes, the statement said. http://www.cidrap.umn.edu/cidrap/content/influenza/general/news/jan0708test.html

Acambis reports promising results for 'universal' flu vaccine

Editor’s Note: This article was modified Jan 8 to include more information about the Acambis preclinical study.

Jan 4, 2008 (CIDRAP News) – British technology company Acambis yesterday announced positive results for a phase 1 clinical trial of an influenza vaccine that it hopes could guard against seasonal and pandemic flu strains and end the need to reformulate the flu vaccine each year.

The vaccine, called ACAM-FLU-A, is designed to target all influenza A virus strains, Acambis said in a press statement yesterday. If clinical trials show the vaccine is effective, Acambis' product could represent major progress toward a universal flu vaccine that would protect against both influenza A and B. Type A influenza cases make up the majority of laboratory-confirmed flu cases in the United States each year.  http://www.cidrap.umn.edu/cidrap/content/influenza/general/news/jan0408vaccine.html
