Pilot Study of Wireless Observed Therapy With an Ingestible Micro-Sensor Among Patients With Heart Failure and Left Ventricular Assist Devices
In Brief
A clinical study evaluating PROTEUS-SENSOR for Heart Failure and Medication Compliance. Completed, enrolled 10 participants across 1 site.
Detailed Summary
The investigators aim to develop a novel and wireless method for monitoring medication adherence among heart failure patients with left ventricular assist devices (LVADs). Proteus Digital™ has developed an ingestible and bio-absorbable micro-sensor as a strategy to monitor medication compliance. The edible sensor has at its core a silicon-based integrated circuit measuring 1.0 mm x 0.45 mm and is imbedded on a pill. Once ingested, this circuit is activated by gastric acid resulting in an electrochemical redox reaction and an electrical charge that is transmitted to a patch worn over the abdomen and wirelessly to a portable device such as a smart phone. This strategy of medication adherence differs from conventional adherence monitoring including pill counting and patient-recall by precisely tracking medication ingestion.
Study Details
Timeline
Interventions
An edible sensor system, Proteus Digital™ has been developed for electronically confirming medication adherence, gathering physiologic metrics and communicating these data to patients. The system consists of two major components: an edible sensor and a wearable receiver health monitor. An electrical signal is activated upon ingestion of the Proteus Digital micro-sensor with transmission of this signal to a receiving abdominal patch to quantify medication compliance.
