LabCorp introduces HIV-1 next generation sequencing assay

Laboratory Corporation of America Holdings and Monogram Biosciences, part of the LabCorp Specialty Testing Group, announced the launch of HIV GenoSure Archive , the first laboratory test to help optimize antiretroviral (ARV) drug regimens in virally suppressed HIV patients.

GenoSure Archive was developed using the Next Generation Sequencing (NGS) platform.

Advances in HIV drug therapy have allowed patients to achieve and maintain complete suppression of viral replication. Life-long treatment, however, is necessary to maintain viral suppression. Such treatment therapies often have adverse side effects, and as new, more simplified ARV drug regimens become available, patients may benefit from new therapies.

Previous laboratory testing to guide ARV drug selection required higher viral loads than what many patients have, leaving clinicians without a reliable diagnostic tool to guide ongoing therapy choices.

HIV GenoSure Archive is the first genotypic drug resistance assay specifically designed to reliably identify the HIV DNA compartment, and it provides physicians and other HIV care providers with critical diagnostic information to support individualized and updated therapies for patients with low or undetectable viral loads of HIV-1.

"The launch of GenoSure Archive addresses an emerging need of today’s HIV patients and their care providers, who are increasingly faced with choices to maintain or adjust ARV drug regimens when the patient has low or undetectable plasma virus. GenoSure Archive gives clinicians the specific knowledge needed to better monitor or adjust their patients’ antiretroviral drug regimens," said Christos Petropoulos, Ph.D., Vice President of Research and Development at Monogram Biosciences.

GenoSure Archive is performed by amplifying cell-associated HIV-1 DNA from infected cells in whole-blood samples and then analyzing the polymerase (pol) region using NGS methods. The assay is analytically validated to identify mutations associated with resistance to all members of the most widely utilized ARV drug classes.

GenoSure Archive evaluates the full-length protease and integrase coding regions and amino acids 1 to 400 of the HIV-1 reverse transcriptase region. Resistance interpretations leverage Monogram’s database of over 150,000 matched phenotype and genotype test results.

GenoSure Archive was developed and is now available for patient testing and clinical trials exclusively through Monogram Biosciences. Monogram is an established leader in resistance testing, with over 15 years of experience in HIV drug resistance assay development.
