Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Introduction of antiretroviral therapy (ART) has transformed HIV-infection from a fatal to manageable disease but adherence to ART remains critical to optimize outcomes. Existing measures of ART adherence provide only inferred measures of actual drug intake and most offer no real-time notification capability. Directly observed therapy measures actual drug intake but is not practical. These limitations constrain research into medication adherence and more importantly, limit our ability to develop real-time interventions based on feasible, in vivo monitoring of adherence among HIV-infected people to facilitate medication-taking. The Proteus digital health feedback (PDHF) system, a pill ingestible sensor based adherence measuring and monitoring system developed by Proteus Digital Health, addresses these limitations. It involves use of an ingestible sensor, a tiny edible material that is over-encapsulated along with prescribed medication. The sensor is activated by ingestion and is sensed by a patch worn by the patient with an embedded monitor and sensor. The monitor sends a Bluetooth signal to a mobile device, which in turn sends an encrypted message to a central server, thus effecting real-time monitoring that a dose has been taken. The investigators propose to develop a data receiving hub and add to these components an automated text message that is sent to the patient when a dose is missed. The investigators will evaluate the feasibility, acceptability and sustainability of using the PDHF system; assess the accuracy of the PDHF system in measuring adherence to ART; and evaluate the efficacy of the PDHF system for monitoring and leveraging adherence to ART.
