UR+AIMS Gout Wearable Skin Uric Acid Monitor Study
Sponsor:

University of California, Los Angeles

Information provided by (Responsible Party):

John D. Fitzgerald, MD, PhD

Brief Summary:

15 patients with gout \[10 patients no recent urate-lowering therapy (ULT) and 5 patients on stable urate-lowering therapy (ULT)\] will be invited to participate in a standardized meal at the UCLA Human Nutrition Center and a 7-day community follow-up for the measurement of uric acid (and other metabolites) using our Uric Acid and Metabolite Monitor System (UR+AIMS) skin patch.

Condition or disease

Gout

Intervention/treatment

Uric Acid and Metabolite Monitor System (UR+AIMS) skin patch

Phase

NA

Detailed Description:

First Visit at the UCLA Human Nutrition Center: * Patients will sign the informed consent, then answer some study questionnaires. * The Uric Acid and Metabolite Monitor System (UR+AIMS) skin patch and the study mobile device will be provided. * Study nurse will start an IV for pre and post blood draws. * Patients will be provided a standardized high-purine meal within 15 minutes. Pre-blood is drawn right before the patients eat the meal, then post-blood will be drawn every 15 minutes for the first hour after completion of the meal, then every 30 minutes for the next 3 hours (total of 4 hours). * Then patients will be sent home with the skin patch and study mobile device. Community 7-day observation period: * Patients will be asked to apply a study patch each morning before their first meal of the day. The patch should be removed at the end of the day and put under water. * The study device will monitor the patient's UA, glucose, heart rate, blood pressure, daily steps, and sleep. Patients will be asked to enter before and after meal uric acid levels and may be asked to take a picture of their meals using the study mobile device.
