Brief Summary

This study uses an ingestion sensor and a wearable sensor (worn as a patch on the skin), which are new Proteus Digital Health (PDH) technologies approved by the FDA, to collect information about patients taking their ARV medications. The wearable sensor records information, which is uploaded wirelessly to a mobile device and then to a secure computer. Together the sensors and the mobile device transmitting the information to the study computer are called a digital health feedback system (DHFS), which gives healthcare providers information about when patients have taken their ARV medications.

The purpose of the study is to demonstrate that the DHFS is easy to use and acceptable to the HIV patient population; that patients will persist with its use; and that the system provides valid, accurate measures of adherence.

Detailed Description

This study is a prospective single arm open label intervention study over 16 weeks using the DHFS with ARV-naive subjects initiating HIV treatment. The study intervention has an initiation (Phase 1), persistence (Phase 2) and follow-up period up to 96 weeks. In phase 1 Subjects will use the DHFS with close follow-up incorporating visits with directly observed ingestions. In Phase 2 the Subjects utilize the DHFS in their natural setting with sporadic study visits until 16 weeks. Eligible HIV seropositive subjects who are at least 18 years of age, are HIV treatment naïve, and are initiating antiretroviral therapy prescribed by their HIV practitioner will receive an ingestible sensor enabled oral Anti-Retroviral or IS-ARV either IS-R/F/TAF (Odefsey®), IS-EC/F/TAF (Genvoya®), IS-BIC/F/TAF (Biktarvy®), IS-DTG/TDF/FTC (Tivicay® and Truvada®) or IS-DTG/TAF/FTC (Tivicay® and Descovy ®). The study will be conducted at the UCSD AVRC. Subjects will be recruited from UCSD AVRC, UCSD Owen Clinic, related or affiliated UCSD HIV primary care programs or community HIV primary care clinics. Following the 16 week intervention HIV plasma viral load and continuation in HIV care are followed for up to 96 weeks. The primary outcome will be an accurate measure of adherence i.e. the number of doses of selected IS-ARVs ingested, as captured by the DHFS, over the number of doses prescribed, adjusted for PDA. The investigators will also assess the acceptability and feasibility of longitudinal monitoring in real time of the ingestion rate utilizing the DHFS. In addition the investigators will evaluate the ability of the DHFS to identify subjects whose longitudinal medication taking and timing patterns in the first 16 weeks of ARV treatment puts them at risk for detectable HIV RNA levels as far out as 96 weeks from start of treatment.

PHARMACOKINETIC (PK) SUBSTUDY

A subset of 15 participants prescribed an IS-Dolutegravir regimen will be enrolled in a PK sub-study to generate a projected time-course of drug concentrations across the entire study period. On Day 14 of treatment sub-study participants will have a detailed PK profile for Dolutegravir obtained over a single dosing interval.

Participants will also have random plasma Dolutegravir levels measured at 4, 8, 12, and 16 weeks during the DHFS monitoring.Plasma HIV-1 RNA and CD4+ T-cell count will be measured at study entry.

At the start of the IS-Tivicay, participants included in the PK study will undergo intensive monitoring of viral decay dynamics with plasma HIV-1 RNA measured at baseline and Days 2, 7, 10 and 14, as well as at Weeks 4, 8, 12, and 16 to provide the dynamic range of virologic suppression relative to drug exposure profiles generated from the intensive PK sampling on Day 14 and the DHFS dosing history.

Study Groups

DHFS with IS-ARV

Digital Health Feedback System (DHFS) with either IS- Odefsey®, IS- Genvoya®, IS-Biktarvy®, IS- Tivicay® and Truvada® or IS- Tivicay® and Descovy ® (IS-co-encapsulated with ingestion sensor) -1 or 2 capsules daily (QD), depending on the treatment regimen, administered orally for 16 weeks.

Group Type: EXPERIMENTAL

Digital Health Feedback System

Intervention Type: DEVICE

This intervention uses an ingestion sensor and a wearable sensor (worn as a patch on the skin), which are new technologies approved by the FDA, to collect information about patients taking their ARV medications. The wearable sensor records information, which is uploaded wirelessly to a mobile device and then to a secure computer. Together the sensors and the mobile device transmitting the information to the study computer are called a digital health feedback system (DHFS), which provides information about when patients have taken their ARV medications.
