Adherence to ARV [ Time Frame: 24 months ] [ Designated as safety issue: No ]
Adherence to ARV medication among HIV positive participants, measured through levels of ARV medication in blood and/or hair
Adherence to ARV [ Time Frame: 24 months ] [ Designated as safety issue: No ]
Adherence to ARV medication among HIV positive participants, measured through WisePill technology
Viral suppression [ Time Frame: 24 months ] [ Designated as safety issue: No ]
For each study visit we will extract viral load and CD4 counts from the positive participant's medical record. If there are multiple reports within 30 days of the study visit, we will use the count nearest in date to the study visit. If there is no report within 30 days of the study visit, this will be treated as missing data. In the case of the sero-conversion of a negative partner, we will also collect viral load and CD4 counts from the newly positive partner at each study visit. Viral suppression will be considered achieved if the medical records report a viral load below the level of detection for the site specific assay

CVCTPlus: A Couples-Based Approach to Linkage to Care and ARV Adherence
CVCTPlus: A Couples-Based Approach to Linkage to Care and ARV Adherence

Men who have sex with men (MSM) continue to be the most heavily-impacted risk group in the US HIV epidemic. Studies suggest that the majority of incident HIV infections among MSM are attributable to sex with a main male sex partner; however, HIV prevention interventions that target male-male couples are lacking. Because of this, Couples HIV Voluntary Counseling and Testing (CVCT), an intervention that has been repeatedly shown to reduce HIV transmission within heterosexual couples, has been adapted to US MSM couples. Additionally, novel evidence demonstrates that antiretroviral therapy (ART) not only reduces morbidity and mortality among HIV-positive persons, but also serves to reduce the risk of HIV transmission to a negative partner by 96%. As adherence to ART is modifiable, and levels of peer support have been shown to increase ART adherence, this current study proposes to use CVCT combined with dyadic adherence counseling ("CVCTPlus") to improve linkage to care, retention in care, ART adherence and viral suppression among male-male couples using a cohort of 200 couples in Atlanta, Boston, and Chicago. Prospective couples (100 in each arm) will be followed for two years, with study visits every six months. At each visit, they will receive HIV testing, and both partners will complete a study survey measuring social and behavioral factors that may influence adherence, such as a couple's coping ability and their concordance of agreements regarding outside sex partners. Additionally, couples in the intervention arm will receive two additional sessions of Partner-STEPS.

Since the earliest reports of AIDS in the United States, men who have sex with men (MSM) have been, and continue to be, the most heavily impacted risk group in the US HIV epidemic. In 2009, MSM accounted for 61% of new HIV diagnoses, an increase from 53% of HIV incidence in 2006. The "test and treat" strategy for HIV infection entails universal testing with immediate treatment for those who test seropositive, with the aim of achieving viral suppression among positives. The efficacy of treatment as prevention demonstrated in HPTN 052 has reinvigorated the discussion over using a "test and treat" strategy to reduce the incidence of HIV infection in the US. However, engagement-in-care research raises a note of caution regarding potential pitfalls in the effectiveness of this strategy. The recently published MMWR "Vital Signs" Report, showed only 28% of all HIV-infected persons in the US has a suppressed viral load. The estimates published by Gardner show that of the estimated 1.1 million persons infected with HIV in the United States, 21% of HIV-infected persons are currently undiagnosed. Of those who are diagnosed, losses occur at initial linkage to care and later in care such that only 50% remain in care, such that only 19% of HIV-infected persons in the US currently having viral load below the limits of assay detection. There is now substantial evidence of the role of couples - or main partnerships - in fueling the HIV epidemic among MSM in the US. A recent CDC analysis found that 68% of new infections among MSM in the US were ascribed to main sex partners, and the proportion of new infections from main sex partners was even higher among younger MSM. Led by Sullivan and Stephenson, recent work has illustrated the feasibility of enrolling couples into HIV prevention efforts, demand for couples-focused services among MSM. A response to the growing demand for couples-focused services has been the adaptation of Couples Voluntary Counseling and Testing (CVCT) for MSM in the US. A recent NIMH-funded RCT of CVCT versus traditional VCT among MSM (Sullivan PI) showed 22% of MSM couples to be sero-discordant. This collective evidence provides the foundation for the proposed activities; we know that a significant proportion of new HIV infections occur within couples, and we know that current levels of linkage to care, retention in care and adherence to ARVs are below par among US MSM. In April 2012, WHO released new guidelines for Couples HIV testing and counseling, including ARV for treatment and prevention among sero-discordant couples [7]. The guidelines report a significant gap in evidence around the uptake and adherence to ARV among couples, and the role of CVCT in shaping uptake and adherence to ARVs: the proposed research has the potential to add significantly to our understanding of these issues. The proposed activities investigate the utility of CVCT combined with dyadic adherence counseling for improving linkage to care, retention in care and adherence to ARVs. Through the screening of 1250 MSM couples and the enrollment of couples in a RCT across 3 cities (Atlanta, Boston and Chicago) the study aims to examine the impact of CVCTPlus (CVCT plus dyadic adherence counseling) versus VCT on linkage to HIV care, retention in HIV care, adherence to ARV and achievement of viral suppression among MSM couples. The specific aims are:

Primary Aims:

  1. Enroll and screen 1250 MSM couples across 3 cities (Atlanta, Boston and Chicago) for HIV, randomizing 625 couples to receive CVCT and 625 couples to receive VCT.
  2. From the initial screening, identify and enroll a cohort of 200 couples to be followed-up for a period of 2 years: couples in the intervention arm will receive CVCTPlus (couples testing plus a couples-focused adherence intervention).
  3. Compare linkage to HIV care, retention in care, adherence to ARVs and achievement of viral suppression between couples originally diagnosed in the intervention (CVCTPlus) and the control (VCT) arms.

Hypothesis: Couples who receive a package of CVCT and a dyadic-focused adherence intervention will achieve greater linkage to care, retention in care, adherence to ARVs and viral suppression than couples who receive the standard of care (individualized VCT and adherence counseling).

With increasing evidence of the role of ARVs in reducing HIV transmission, MSM couples represent a significant target group for new interventions. The proposed activities will provide new information demonstrating the efficacy of using a couples-based approach for increasing ARV adherence and care seeking among couples.

Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver)
Primary Purpose: Prevention
HIV
Behavioral: CVCTPLUS
For the intervention, couples will receive HIV testing and counseling together as a dyad, and some couples will receive ARV adherence counseling (Partner-STEPS) together as a dyad.
Other Names:
  • Dyadic STEPS
  • Partner STEPS
  • No Intervention: Control group (iVCT)
    Male couples randomized to the control group (iVCT) will each receive individual HIV counseling and testing, separately. From this group, some couples will be invited to enroll in the prospective RCT. These couples in the control group (iVCT) will return every 6 months, up to 24 months, for individual visits, in which they will have STI testing and repeat HIV testing. All follow-up visits will be conducted separately.
  • Experimental: Experimental group (CVCTPLUS)
    Male couples randomized to the experimental group (CVCTPLUS) will each receive HIV counseling and testing as a couple. From this group, some couples will be invited to enroll in the prospective RCT. These couple will return for two additional visits that members of the control arm do not get, for two one-hour sessions of the Partner-STEPS. Couples in the experimental group (CVCTPLUS) will also return every 6 months, up to 24 months, for visits in which they will be seen as a couple, in which they will have STI testing and repeat HIV testing. All follow-up visits will be conducted for the couples together.
