Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will investigate the use of a next-generation Reader as part of a digital pill system (DPS; ID-Cap System) to measure adherence to both antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) in people living with HIV (PLWH) and HIV-negative individuals, respectively. During the first (non-human subjects) component of this study, we developed a wrist-borne Reader according to design specifications and preferences shared by DPS users from our previous studies. Early bench testing by etectRx (manufacturer of the ID-Cap System) demonstrated that the wrist-borne version of the Reader acquires signal from the digital pill. This study will therefore evaluate the usability of and user response to a wrist-borne Reader component of the DPS among PLWH on ART and HIV-negative individuals on PrEP.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a single-arm, observational trial (N=30), which will enroll N=15 people living with HIV (PLWH) using Biktarvy as antiretroviral therapy (ART) and N=15 HIV-negative individuals using Truvada as pre-exposure prophylaxis (PrEP). Potential participants will be approached and pre-screened. Those who meet pre-screening criteria will attend a Screening Visit (Visit 1), where the informed consent process will be conducted and eligibility will be confirmed. Eligible participants will attend a total of 3 study visits: the Screening Visit (Visit 1), Enrollment Visit (Visit 2), and Month 1 Visit (Visit 3). Participants will take one digital pill per day (Biktarvy as ART or Truvada as PrEP) for 30 days total, while using the next-generation Reader with a digital pill system, the ID-Cap System. Timeline followback discussions will be conducted at the Month 1 Visit to understand the context of any nonadherence detected by the digital pill system. Qualitative user experience exit interviews, quantitative assessments, dried blood spots (DBS), and pill counts of unused medication will also be conducted at the Month 1 Visit.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

PrEP Participants

Participants will ingest one Truvada digital pill as PrEP per day, for 30 days total, while using the next-generation Reader and ID-Cap System.

Group Type EXPERIMENTAL

Next-generation Reader and ID-Cap System

Intervention Type DEVICE

The digital pill system (DPS) is comprised of an ingestible radiofrequency emitter, integrated into a standard gelatin capsule, which then over-encapsulates the study medication (PrEP or ART). On ingestion, the radiofrequency emitter is activated by chloride ions in the stomach, projecting a signal approximately three feet off the body. This radio signal is acquired by a wearable device (Reader) which stores and forwards data to a smartphone, enabling on-demand access to adherence data. The next-generation Reader is a wrist-borne device.

Truvada for pre-exposure prophylaxis (PrEP)

Intervention Type DRUG

Participants will ingest one Truvada digital pill as PrEP per day, for 30 days total.

ART Participants

Participants will ingest one Biktarvy digital pill as ART per day, for 30 days total, while using the next-generation Reader and ID-Cap System.
