Brief Summary:
To assess the acceptance rate, adherence, acceptability, and continuation of oral pre-exposure prophylaxis (PrEP) among young southern African women.

Condition or disease Intervention/treatment Phase
HIV Drug: Truvada Phase 4

Detailed Description:
A Phase IV randomized multi-site prospective study to assess PrEP acceptance and adherence among HIV-uninfected young women. All women who accept open-label daily oral PrEP will be randomized 1:1 to receive enhanced adherence counselling based on feedback from observed drug levels or standard adherence support. A subset of up to ~25 women per site (maximum 75), will participate in qualitative assessments of facilitators and barriers for PrEP acceptance, adherence and continuation.

  • Planning to relocate in the next 12 months
  • Has a job or other obligations that would require long absences from the area (> 4 weeks at a time) for 12 months
  • Any health condition that may interfere with participation, including any debilitating or life-threatening conditions
  • Currently pregnant or planning to become pregnant in the next 12 months

  • Any reported PrEP use within the last 12 months
  • Concomitant participation in a clinical trial using investigational agents, including placebo-controlled clinical trials using such agents
  • Prior participation in the active arm, or current participation in any arm, of an HIV vaccine trial
  • Signs or symptoms of acute HIV infection (as described in the SSP Manual)
  • Current active and serious infections which could interfere with study participation, including active tuberculosis infection, osteomyelitis, and all infections requiring parenteral antibiotic therapy (other than STIs requiring intramuscular injections of antibiotics); active clinically significant medical problems including poorly-controlled cardiac disease (e.g., symptoms of ischemia, congestive heart failure), or previously diagnosed malignancy expected to require further treatment.

  • Any other condition that, based on the opinion of the site Investigator of Record (IoR) or designee, would preclude provision of informed consent, make participation in the project unsafe, complicate interpretation of outcome data, or otherwise interfere with achieving the project objectives.
