About this study

Official title: Evaluation of Life-Steps to Enhance Adherence and Engagement in PrEP Care

The purpose of this study is to test how different types of interventions may affect how someone takes their pre-exposure prophylaxis (PrEP) medication.

Conditions: Adherence, Medication
Being tested: Lifesteps for PrEP, Daily text message reminders
Keywords: Life-Steps, HIV Prevention
Medical subject headings: Medication Adherence

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Lifesteps for PrEPBehavioural
Four weekly nurse delivered counseling sessions plus two optional booster sessions. Sessions last approximately 40-50 minutes each. Sessions employ cognitive behavioral (CBT) techniques, motivational interviewing (MI), and psychoeducation.
Daily text message remindersBehavioural
Participants get daily text messages on their cell phone reminding them to take their PrEP medication.

Study groups in NCT04316715
Study group	Role	What they receive
Life-Steps for PreP	Experimental	Participants in this group will receive standard of care treatment plus daily text message reminders. A subset of participants who demonstrate continued adherence challenges will also receive 4-6 weekly sessions of the Lifesteps for PrEP intervention. Receives: Behavioral: Lifesteps for PrEP; Behavioral: Daily text message reminders
Standard of Care	No intervention	Participants in this group will not receive an intervention outside the standard of care.

What is being measured

The primary outcome is the main question the study is designed to answer.

Participants With TFV-DP Concentrations Consistent With Adherence (≥4 Doses/Week)
Medication adherence as reported by Tenofovir diphosphate (TFV-DP) concentrations measured using dried blood spot (DBS) testing. Measured by the concentration of PrEP medication in dried blood spots (DBS), displaying levels consistent with adherence (4+ pills per week). Outcomes reported categorically as "adherent" vs. "not adherent." Count of participants measures participants with TFV-DP concentrations consistent with adherence (4+ pill per week).
Measured: 3, 6, 9, 12, 15, and 18 months
Wilson Medication Adherence Self-Report
Medication adherence as reported by the Wilson Medication Adherence self-report. The questionnaire has a score ranging from 0-1, with a higher score indicating greater adherence.
Measured: 3, 6, 9, 12, 15, and 18 months

Secondary outcomes (1)

Retention in PrEP Care
The number of participants in attendance at each follow up visit over 18 month study participation
Measured: 3, 6, 9, 12, 15, and 18 months
