NCT05417854

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Within-arm change in the Disease Activity Score (DAS-28-CRP) from baseline to the completion of an up-to 8-week treatment period.

    A decrease in Disease Activity Score indicates an improved outcome.

    8 weeks

Other Outcomes (11)

  • Within-arm change of serum c-reactive protein (CRP) concentration.

    8 weeks

  • Within-arm change of serum erythrocyte sedimentation rate (ESR).

    8 weeks

  • Within-arm change of serum cortisol levels.

    8 weeks

  • +8 more other outcomes

Study Arms (1)

Ultrasound Group

EXPERIMENTAL
Device: Splenic Ultrasound

Interventions

Daily ultrasound application to the spleen of approximately 18 minutes per day, 5 days per week for up to 8 weeks, in addition to standard clinical care.

Also known as: SecondWave Systems investigational MINI device

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Males and females ages 18 and above
  • Must carry a diagnosis of rheumatoid arthritis, as defined by the American College of Rheumatology in 2010: (https://www.rheumatology.org/Portals/0/Files/2010\_revised\_criteria\_classification\_ra.pdf)
  • \- Classification as "definite RA" is based on the confirmed presence of synovial thickening in at least 1 joint, absence of an alternative diagnosis that better explains the synovitis, and achievement of a total score of 6 or greater (of a possible 10) from the individual scores in 4 domains: number and site of involved joints (score range 0-5), serologic abnormality (score range 0-3), elevated acute-phase response (score range 0-1), and symptom duration (2 levels; range 0-1)
  • Exhibiting symptoms or signs of inadequate inflammatory disease control according to one of two measures:
  • Multidimensional HAQ score of greater than 0.3
  • DAS-28-CRP greater than 3.2 (http://www.phusewiki.org/wiki/index.php?title=Disease\_Activity\_Score\_-\_CRP\_(DAS-CRP)
  • Candidate participant's rheumatoid arthritis medical therapy should be stable for two weeks leading up to the study. Moreover, participants must be willing to maintain their current medication regimen throughout the study enrollment period (in adjunct to the additional investigational ultrasound treatment)

You may not qualify if:

  • Active bacterial or viral infection
  • Pregnant women or those trying to become pregnant
  • Receiving active chemotherapy or immunotherapy to treat malignancy within 30 days prior to enrollment
  • Having received Rituximab monoclonal antibody medication within 30 days prior to enrollment
  • Presence of an implanted device
  • Asplenia
  • Splenomegaly
  • Ascites
  • Recent abdominal surgery
  • Currently participating in an investigational drug or device study
  • Open wound/sores near stimulation sites
  • Inability to perform minimal daily self-cares associated with feeding/dressing, according to HAQ
  • Any other clinical reasons deemed by the investigators of the study in which the patient would not be an appropriate candidate for the study
