Clinical Trial Summary

This study deploys a novel digital pill with Emtricitabine/Tenofovir (TDF/FTC) among MSM with substance use to monitor PrEP adherence. The investigators will enroll N=15 HIV uninfected MSM with self reported substance use who are on PrEP or initiating PrEP to use digital pills over encapsulating TDF/FTC for 3 months. The investigators will assess the feasibility of using digital pills in this study population as well as understand the acceptability of digital pills for adherence measurement using semi-structured individual interviews. Additionally, the investigators will measure adherence over time, as well as episodes of suboptimal PrEP adherence.


Clinical Trial Description

Eligible study participants will be screened and enrolled at Fenway Health (Boston, MA). Participants will complete a quantitative assessment on their history fo substance use, sexual risk and PrEP adherence, and be trained to use the digital pill for 90 days and instructed to take PrEP daily during the course of the study. Participants will return each month for a study visit to assess their use of the technology. At study visit 1 and 3, we will obtain dried blood spots (DBS) to measure drug levels and to confirm adherence detected by the digital pill. The investigators will also obtain drugs of abuse screens from DBS. At the final study visit (3 months), participants will undergo a semi-structured qualitative interview to understand the user response to digital pills. ;
