Next Generation Ingestible Sensors for Medication Adherence Measurement

Status Active, not recruiting

Clinical Trial Summary

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.

Clinical Trial Description

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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
