HIV-1 Resistance at Screening for HIV Prevention Studies - Full Text View

Purpose

MTN-009 is a multi-site, cross-sectional study that will provide an estimate of the prevalence of ARV resistance in the population of women who present to study sites to be pre-screened or screened for participation in an HIV prevention trial. To date, a comprehensive surveillance of HIV drug resistance in newly diagnosed women of reproductive age has yet to be undertaken. The primary goal of MTN-009 is to assess the frequency of HIV drug resistance mutations among women who test HIV-positive when presenting to screen for participation in HIV prevention trials.

Primary Outcome Measures:

To assess the frequency of HIV drug resistance mutations among women who test HIV-positive when presenting to screen for participation in HIV prevention trials [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To identify and evaluate behavioral indicators including self or sexual partner(s) exposures to ARV drugs as risk factors for drug resistant HIV infection in women who present for screening to participate in HIV prevention trials [ Time Frame: 2 years ] [ Designated as safety issue: No ]
To characterize the degree of immunodeficiency and risk of disease progression by quantifying plasma HIV-1 RNA and CD4-positive T cells among women who test HIV-positive when presenting for screening to participate in HIV prevention trials [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Biospecimen Retention: Samples With DNA

Groups/Cohorts	Assigned Interventions
HIV-infected	Procedure: Laboratory Testing Completion of behavorial questionnaire; HIV testing;CD4-positive T cell counts; Plasma viral HIV-1 RNA levels (viral load); Identification of drug resistance mutations in HIV-1 by standard and sensitive assays; Categorization of infection as recent or chronic using current incidence testing algorithms; Follow-up visits with laboratory evaluations
HIV-uninfected	Other: Counseling/referral Completion of behavorial questionnaire; HIV testing; Referred to HIV-prevention trial;

Detailed Description:

MTN-009 is a multi-site, cross-sectional study that will provide an estimate of the prevalence of ARV resistance in the population of women who present to study sites to be pre-screened or screened for participation in an HIV prevention trial. To date, a comprehensive surveillance of HIV drug resistance in newly diagnosed women of reproductive age has yet to be undertaken. The primary goal of MTN-009 is to assess the frequency of HIV drug resistance mutations among women who test HIV-positive when presenting to screen for participation in HIV prevention trials. Secondary aims include the identification and evaluation of behavioral indicators including self or sexual partner(s) exposures to antiretroviral (ARV) drugs as risk factors for drug resistant HIV infection, as well as the characterization of the degree of immunodeficiency and risk of disease progression by quantifying plasma HIV-1 RNA and CD4-positive T cells among women who test HIV-positive when presenting to screen for participation in an HIV prevention trial. Exploratory aims include the identification of polymorphic or subtype-specific sequence changes in HIV-1 that may impact susceptibility to ARVs, and the estimation of the proportion of HIV-positive women who have chronic versus recent HIV infection.

The finding of significant resistance, or lack thereof, to ARV-based study products delivered vaginally or taken orally may guide decisions related to future microbicide and PrEP studies. In addition, MTN-009 will provide valuable comparison data for the resistance data obtained in MTN-015, the MTN seroconverter study.
