Same as current
  • Change in transmission-risk behavior [ Time Frame: Baseline to 48 weeks ] [ Designated as safety issue: Yes ]
    Changes in sexual risk behavior as assessed via CASI-based self-report questionnaire, measured longitudinally over time.

A Demonstration Project to Add Pre- or Post-exposure Prophylaxis to Combination HIV Prevention Services
A Pilot Demonstration Project to Operationalize Pre-exposure Prophylaxis as Part of Combination HIV Prevention Among MSM and Transgender Women in Los Angeles County

The purpose of this study is to evaluate the safety, acceptability and feasibility of delivery of PrEP or PEP as part of combination HIV prevention services for high-risk MSM and transgender women.

Two community-based sites (Los Angeles Gay and Lesbian Center [LAGLC] and The OASIS Clinic) will serve as facilities at which participants may present for screening for prevention services. At the sites, eligibility criteria will be assessed, HIV, STD and laboratory testing will be performed, and HIV prevention service referrals will be initiated. Follow-up will be on a monthly basis for the first three months, and then de-escalated to an every-3-month interval.

The program stratifies participants into two cohorts on the basis of sexual risk behavior: a low-moderate risk cohort (LM) and a high-risk cohort (H). Participants in the LM cohort will be provided a customized prevention package (CPP) including access to post-exposure prophylaxis (PEP) for emergency HIV prevention in the event of unanticipated HIV exposure. Participants in the H cohort will be provided a CPP including daily Truvada-based PrEP. All participants will be followed for 48 weeks. Participants in the LM cohort who, on longitudinal sexual risk behavior surveillance, report increased levels of sexual risk-taking such that they meet enrollment criteria for the H-cohort will be transitioned to the H-cohort.

At each follow-up visit, a careful safety assessment will be made, including signs/symptoms and laboratory assessments. STI testing will be performed at 3 month intervals. An escalating-intensity adherence intervention will be implemented based on real-time serum tenofovir levels. A computer-assisted self-interview (CASI) will be used to capture detailed sexual risk, adherence, and substance use behavior.

Interventional
Phase 4
Allocation: Non-Randomized
Endpoint Classification: Safety Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Prevention
HIV Prevention
Drug: emtricitabine 200mg/tenofovir 300mg
The intervention medication will be tenofovir + emtricitabine, provided as a fixed-dose combination tablet as Truvada®. Dosing is 1 tablet by mouth once daily. For participants with a a confirmed (i.e. two consecutive) reduction in CrCl to <50 mL/min, Truvada will be dose-reduced to 1 tablet by mouth every other day. For patients with creatinine clearance <30 mL/min, Truvada will be discontinued.
Other Name: Truvada
  • Active Comparator: Cohort H (PrEP)

    Participants in the H cohort will be provided with a CPP (customized prevention package) including daily Truvada-based PrEP(Pre-Exposure Prophylaxis).

    High Risk Cohort Criteria (one or more of the following has to be met):

    1. No condom use during anal intercourse with ≥3 male sex partners who are HIV-positive or of unknown HIV status during the last three months.
    2. STI diagnosis during the last 12 months.
    3. Previous PEP use during the last 12 months (* see exclusion criteria)
    4. Has at least one HIV infected sexual partner for ≥4 weeks.
    Intervention: Drug: emtricitabine 200mg/tenofovir 300mg
  • Active Comparator: Cohort LM (PEP)
    Participants who do not meet criteria for High Risk (Cohort H) will be assigned to the LM (low moderate) cohort and will receive a customized prevention package based on baseline assessments (in the same manner as the Cohort H Participants). In addition, they will receive education on the availability and use of post-exposure prophylaxis.
    Intervention: Drug: emtricitabine 200mg/tenofovir 300mg
