Abstract

Purpose of Review

This review summarizes the recent advancements and future directions of digital pill systems (DPS) — which utilize ingestible sensors to directly measure medication ingestion events in real-time — in the context of HIV prevention and treatment.

Recent Findings

Two DPS are cleared by the US Food and Drug Administration. The bioequivalence and stability of digitized pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART) have been established, and pilot studies have demonstrated the feasibility and acceptability of using DPS for PrEP and ART adherence measurement. Important bioethical and implementation considerations have been identified for future clinical trials. Continued technological advancement may reduce barriers to use, and integration of DPS into behavioral interventions may facilitate adherence improvement efforts.

Summary

DPS represent an innovative tool for PrEP and ART adherence measurement. Future work will optimize the technology to reduce operational barriers. DPS have significant potential for expansion across a diverse array of diseases, though key bioethical considerations must be examined prior to large-scale implementation.
