Test with enhanced reliability for monitoring HIV patients now CE marked

Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that it has received CE mark for the expanded use of its novel HIV test.¹ This allows the test to be used in smaller laboratory settings. In the face of the rapidly growing genetic diversity of HIV-1^2,3 and its implications for the efficacy of antiretroviral therapy, Roche’s new dual target approach ensures enhanced reliability of test results and more confidence in assessing viral loads. Since Roche introduced this innovative strategy in 2008, over 3.2 million tests have been performed using the dual target approach for monitoring HIV patients on antiretroviral therapy.

This dual target approach improves the ability of physicians and laboratories to obtain reliable information about HIV-infected patients, said Paul Brown, PhD, Head of Roche Molecular Systems. Roche is committed to developing and providing new diagnostic tools such as this dual target approach that will better serve all laboratories performing viral load tests for HIV patients, including laboratories performing clinical trial and research-related studies that have specific needs.

The dual target strategy

The dual target strategy improves accuracy in quantifying HIV-1 subtypes by avoiding the effects of rare mismatches in primer/probe binding sites of a target region by simultaneously detecting and amplifying 2 separate regions of the HIV-1 genome. The test utilizes the High Pure System Viral Nucleic Acid Kit for manual specimen preparation and the COBAS TaqMan 48 Analyzer for automated amplification and detection.

About HIV

According to UNAIDS, there were 33.3 million people living with HIV around the world in 2009. In that same year, 2.6 million people became newly infected with HIV— almost 20 percent fewer than in the late 1990s.⁴ Highly active antiretroviral treatment (HAART) and viral load tests, a test to determine the amount of circulating HIV, have contributed to a steady increase in life expectancy for HIV-infected people by 13 years.⁵
