Detailed Description
This is an open-label single-arm longitudinal clinical trial to estimate medication adherence and retention in a PrEP HIV prevention program that implements a combination intervention strategy that uses text-messages (iTAB) and a staged adherence counseling support strategy titrated from real-time drug levels in women at-risk for HIV acquisition.
A total of 135 participants will receive the combined intervention of text messaging adherence reminders and adherence support. The text messaging system consists of daily, personalized, automated 2-way text messages to maintain adherence and retention. Participants that have a low intracellular tenofovir diphosphate (TFV-DP) concentration will receive escalated, targeted adherence support. All participants will receive access to PrEP in accordance with standardized comprehensive methods of prescribing and clinical assessments that include safety monitoring as well as regular HIV and sexually transmitted infection (STI) screening. All participants will be followed for 48 weeks after enrollment and will receive a post study follow-up at 60 weeks. The primary endpoint will be measured at 48 weeks.

- Creatinine clearance ≥ 60 ml/min (via Cockcroft-Gault formula)
At-Risk Criteria (at least one):
- Condomless sex in the last 3 months with one or more male partners of unknown HIV status known to be at substantial risk of HIV infection (IDU, bisexual, sex for goods, recently incarcerated, from a country with HIV prevalence >1%, interpersonal Partner Violence);
- STI (rectal or vaginal gonorrhea or syphilis) diagnosis during the last 6 months.

Exclusion Criteria:

---|---|
Other: AEGIS
All participants will be assigned to this arm of the study.
|
All participants assigned to the iTAB intervention will receive daily dosing reminders that will be sent for the first 6 weeks and then continue with reminders for the duration of the study.
Other Names:
All participants assigned to the counseling intervention will receive sexual health and medication adherence counseling at each study visit.
Participants with suboptimal adherence (TFV-DP levels of <1050 fmol/punch (representing fewer than mean 6-7 daily doses per week)) will trigger a targeted iNSC session.
Participants with two TFV-DP levels of <1050 fmol/punch will trigger PrEP Steps, a higher intensity adherence counseling intervention consisting of four 50-minute counseling sessions and 2 booster counseling sessions.
Other Names:
All participants will be offered daily oral emtricitabine/tenofovir disoproxil fumarate for Pre-exposure Prophylaxis.
