Summary

Poor adherence to tenofovir (TDF) and emtricitabine (FTC) for Human Immunodeficiency Virus (HIV) pre-exposure prophylaxis (PrEP) is common and the leading cause of therapeutic failure. The investigators need better ways to measure adherence in patients on PrEP. This application will address the need to measure adherence by evaluating an integrated technology system, Proteus Discover, when combined with Truvada. The Proteus Sensor System (PSS) will confirm that Truvada was taken, monitor adherence in both recent and long term dosing, and provides feedback to encourage adherence. The goal of this study is to determine whether the use of the PSS with Truvada will vary the drug concentrations of FTC/TDF. Participants will have 2 study visits where they will be randomized to either start with the combined PSS with Truvada or just Truvada alone. Study participants will come to the Clinical \& Translational Research Center (CTRC) in the morning and take the assigned dose and will then have blood drawn at about .25, 0.5, 1, 2, 4, 6, and 10 hours after medication is taken. Participants will then return to the CTRC for blood draws 24, 48, and 72 hours after they took the dose on the first day. The second visit will mimic the first except that the participant will take the other dose form.
