This study is designed to test the hypothesis that, compared to oral PrEP, use of CAB-LA in underserved populations in a real-world setting supported by a digital health companion program will be associated with greater medication adherence, persistence, retention-in-care, and improved PROs. Patients in the study will receive current standard care for HIV prevention and be offered enrollment in the digital health companion program. Goal of the study is to evaluate medication adherence and persistence in patients receiving CAB-LA vs oral PrEP and who engage with a digital health companion program.
