Detailed Description

The goal of this Phase I study is to conduct a proof-of-concept trial of a contingency management (CM) targeting adherence to oral HIV antiretroviral pre-exposure prophylaxis (PrEP) administered via a smartphone-based medication adherence platform (PrEP SMART, "the app").

PrEP provides a strong preventative benefit to individuals at-risk for HIV. While oral PrEP adherence is highly correlated with its efficacy in clinical trials, adherence rates are variable and range from 29-80%. In real-world practice settings, PrEP adherence may even be lower. As such, interventions are needed to improve and sustain adherence to oral PrEP, thereby maximizing preventative benefits in at-risk populations.

CM is a behavioral intervention that involves the systematic use of reinforcement dependent on the occurrence of a predefined behavior. CM improves adherence to antiretroviral therapy and post-exposure prophylaxis, but CM has yet to be applied to PrEP adherence. The investigative team recently developed a smartphone-based platform for medication adherence that can integrate CM. Given that mobile technologies such as smartphones are increasingly ubiquitous, a CM-based program administered via smartphone may be a practical intervention that augments PrEP adherence.

In the proposed research, PrEP SMART will provide medication reminders; monetary incentives for daily, verified adherence to PrEP; education about oral PrEP; and assess potential adherence barriers. This will be a 4-week open-label, stage I trial in a community sample of young men who have sex with men (YMSM, n = 12) already prescribed and taking oral PrEP (ages 18-30). YMSM were selected because they are the only high risk group experiencing an increase in HIV incidence in the U.S.

The investigative team is particularly well-positioned as we have expertise in the development of mobile apps to improve medication adherence, including in the context of HIV care; oral PrEP efficacy trials; and are conducting research using the "parent version" of PrEP SMART (mSMART; Mobile App based Personalized Solutions and Tools for Medication Adherence of Rx Pill) platform in another clinical context.

The primary aim of this study is to conduct a proof-of-concept trial of PrEP SMART.

  • Aim 1a: User interaction with the app will allow for evaluation of feasibility (e.g., the number of app uses/day)
  • Aim 1b: Acceptability will be assessed via self-report ratings and qualitative interviewing
  • Aim 1c: Medication adherence will be evaluated via daily smartphone camera-based medication event assessments to establish preliminary data on the impact of mSMART for future efficacy trials.
  • Aim 1d: Adherence barriers will be evaluated by mSMART following missed doses.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 30 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Men who have sex with men and already prescribed and taking oral PrEP will use an application on their smart phone for 4 weeks.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Feasibility as measured by the average number of times per day participants initiate an interaction with PrEP Smart
Time Frame: 4 weeks
4 weeks
Feasibility as measured by the average number of times per day subjects respond to a prompt from PrEP Smart over the course of the four week period.
Time Frame: 4 weeks
4 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Barriers to adherence following missed doses as measured by daily PrEP Smart assessment.
Time Frame: 4 weeks
4 weeks
Acceptability as measured by questionnaire that includes questions about satisfaction and likelihood of recommending to others on a Likert scale of 1 to 4.
Time Frame: 4 weeks
4 weeks
Acceptability as measured by an interview that will be conducted by the Principal Investigator.
Time Frame: 4 weeks
4 weeks
Barriers to adherence will be measured by the number of times it was taken outside of a 1 hour window
Time Frame: 4 weeks
