Ultrasonic Treatment of Food Addiction

Phase 1

Withdrawn

• Conditions: Obesity; Overweight

• Registration Number: NCT06249711
• Lead Sponsor: University of Utah

Brief Summary

This study will evaluate a new form of non-invasive deep brain therapy for food addiction. Low-intensity transcranial focused ultrasound stimulation will first be delivered using a range of stimulation parameters during psychophysical and physiological monitoring. A well-tolerated stimulation protocol will be selected for subsequent testing in a blinded randomized sham-controlled trial. The trial will evaluate brain target engagement using magnetic resonance imaging, Food Cravings Questionnaire-State, and changes in subject's weight over the course of the study.

Primary Outcome Measures

Name	Time	Method
Change in body weight (%) from baseline week 0 to week 16	The body weight will be taken prior to each intervention (once per week)	The body weight will be quantified with respect to baseline (100%), taken prior to the first intervention.
Number of participants who achieved body weight reduction >= 5%	Assessment at week 16	Proportion of subjects who have lost at least 5% of their weight at week 16 relative to the baseline week 0.
Food Cravings Questionnaire-State	During and immediately after each weekly intervention	This 15-item questionnaire measures immediate level of food craving, each item ranging from 1 (strongly disagree) to 5 (strongly agree). Higher total scores indicate stronger desire to eat.
Hamilton Depression Rating Scale, 17 item	For up to 16 weeks	This 17-item questionnaire measures the severity of depression. Scores range between 0 (least severe) to 52 (most severe).
