Ultrasound Treatment for Rheumatoid Arthritis Study [ULTRA Study] — ULTRA  

Rheumatoid Arthritis Clinical Trial

Official title: Ultrasound Treatment for Rheumatoid Arthritis Study [ULTRA Study]

Status Completed

Clinical Trial Summary

The research objective is to assess efficacy of spleen ultrasound stimulation in the treatment of rheumatoid arthritis (RA) in a pilot study.

Specific Aims:

• Measure RA disease activity and clinical metrics during and after an 8-week course of spleen-directed daily ultrasound treatments.

• Measure molecular correlates, including Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), cortisol and cytokine levels, of rheumatoid arthritis disease activity during spleen-directed daily ultrasound treatments.

Clinical Trial Description

Ultrasound is widely used in human medicine because it is safe, non-invasive, and painless. The same kind of ultrasound that is used for imaging (for example, to visualize babies in utero) may be able to treat inflammatory diseases including Rheumatoid Arthritis.

Multiple studies in animals with hyper-inflammation conditions (e.g., inflammatory arthritis and sepsis/lipopolysaccharide [LPS] injections) and recent human studies (e.g., for the treatment of joint inflammation in Rheumatoid Arthritis) have shown that ultrasound applied to the spleen can suppress blood/genetic markers of inflammation.

This study will employ investigational ultrasound devices produced by SecondWave Systems called the MINI ultrasound system.

This is a pilot single-arm treatment trial in which up to 15 study participants will receive noninvasive splenic-ultrasound therapy over eight weeks (five daily stimulation sessions per week). Clinical outcomes will be compared from baseline to end of the 8-week treatment period. Investigational splenic-ultrasound therapy will be delivered with the SecondWave MINI ultrasound system. The objective of the study is to assess the safety and potential efficacy for the MINI system for treatment of Rheumatoid Arthritis.

For ultrasound stimulation, a small wearable ultrasound device is positioned on the upper left abdomen area over the ribs. Study personnel will use an ultrasound imaging device to locate the spleen and to position the wearable MINI device in a proper location around the ribs area. Daily stimulation consists of an approximately 18-minute period for application of ultrasound to the spleen. Collection of clinical outcome data, patient-reported assessments, and blood draws collected at the 5 study visits to assess biomarkers of inflammation will be performed in each participant throughout the study. ;
