Study Summary
The purpose of this study is to compare the effectiveness of two mobile health technologies (text messaging or a mobile app) designed to help people take HIV pre-exposure prophylaxis (PrEP) as directed by the clinic. PrEP is the use of a daily anti-HIV medications by HIV-negative people to help prevent HIV infection.
Primary Outcome
PrEP adherence will be measured by tenofovir diphosphate (TFV-DP) levels in dried blood spots (DBS). Adequate adherence will be defined as having a TFV-DP ≥ 700 femtomoles/punch in DBS for daily PrEP users, which has been associated with high levels of protection in prior PrEP trials.
