Sustained Acoustic Medicine (SAM) for Symptomatic Treatment of Pain Related to Bone Fracture

Phase 1

Recruiting

• Conditions: Bone Fracture; Fresh Fracture
• Interventions: Device: Sustained Acoustic Device with 2.5% Diclofenac Patch; Drug: 2.5% Diclofenac Patches

• Registration Number: NCT05883241
• Lead Sponsor: ZetrOZ, Inc.

Brief Summary

The purpose of this study is to assess the ability of long-duration low-intensity therapeutic ultrasound (LITUS) to alleviate bone-fracture related pain over a 12-week period.

The primary objective of this study is to evaluate the analgesic effect of LITUS in subjects suffering from bone-fracture pain.

Secondary objectives are to assess the ability of LITUS to improve patients return to work time.

Detailed Description

This is a 12-week study to clinically evaluate the effectiveness of the Sustained Acoustic Medicine (SAM) device combined with diclofenac on symptoms of patients suffering from pain related to a bone fracture(s). The class-II device, sam®, has been FDA-cleared for home use. On the first day of the study, baseline data will be collected as patients report pain score before treatment. During the following 12 weeks, patients will self-apply their treatment for the 4 hours daily. Each day of the study, pain scores will be recorded immediately before application of SAM device, during treatment, and at the completion of treatment.

Over 90 subjects will be recruited from neighboring communities to the study site(s). The study is designed to reach a diverse target patient population.

Inclusion Criteria

• Have physician-diagnosed bone fracture
• Are between 18-80 years of age
• Report a pain score between 3-7 (range: 0-10) prior to enrolment
• Report that pain from fracture negatively affects quality of life
