NCT07226648

Brief Summary

The goal of this clinical trial is to evaluate a new noninvasive brain stimulation intervention for fibromyalgia and to determine its effectiveness in reducing pain. Participants will receive four treatments over the course of one month and will complete surveys at multiple time points throughout the 16-week study.

Outcome Measures

Primary Outcomes (1)

  • Numerical Rating Scale - 11 (NRS-11) pain score

    The NRS-11 is a scale from 0-10 with higher values representing higher levels of pain.

    28 days following initial treatment

Secondary Outcomes (7)

  • Fibromyalgia Impact Questionnaire Revised (FIQR)

    28 days following initial treatment

  • Numerical Rating Scale - 11 (NRS-11) pain score response rate

    28 days following initial treatment

  • Patient-Reported Outcomes Measurement Information System (PROMIS-29) - Pain Interference Subscale

    28 days following initial treatment

  • Numerical Rating Scale - 11 (NRS-11) pain score response rate

    7 days following initial treatment

  • Patient Global Impression of Improvement (PGI-I)

    28 days following initial treatment

  • +2 more secondary outcomes

Other Outcomes (11)

  • Patient-Reported Outcomes Measurement Information System (PROMIS-29) - all subscales, excluding Pain Interference

    28 days following initial treatment

  • Brief Pain Inventory (BPI) - short form

    28 days following initial treatment

  • Fibromyalgia Impact Questionnaire Revised (FIQR)

    16 weeks following initial treatment

  • +8 more other outcomes

Eligibility Criteria

Age22 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Willing and able to provide informed consent.
  • Age ≥ 22 years.
  • Meets 2016 American College of Rheumatology criteria for fibromyalgia:
  • Generalized pain, defined as pain in at least 4 of 5 regions, is present, AND
  • Widespread pain index (WPI) ≥ 7 and symptom severity scale score (SSS) ≥ 5, or WPI of 4-6 and SSS score ≥ 9, AND
  • Symptoms have been present at a similar level for at least 3 months, AND
  • A diagnosis of fibromyalgia is valid irrespective of other diagnoses. A diagnosis of fibromyalgia does not exclude the presence of other clinically important illnesses.
  • Failure of at least two evidence-based medications (i.e., pregabalin, duloxetine, milnacipran) for the treatment of fibromyalgia.
  • Failure of one or more attempts at physical or Cognitive Behavioral Therapy (CBT) including:
  • Aerobic exercise like walking, cycling, and swimming,
  • Water therapy/hydrotherapy with warm water exercises,
  • Tai Chi involving slow, controlled movements,
  • Yoga,
  • Resistance training,
  • Bodyweight exercises,
  • +25 more criteria

You may not qualify if:

  • Any previous diagnosis of bipolar disorder or schizophrenia-spectrum disorder during the participant's lifetime, according to Diagnostic and Statistical Manual of Mental Disorders, version 5 (DSM-5-TR) criteria.
  • New or existing diagnosis of moderate or severe alcohol or other substance use disorder in the past 6 months, according to DSM-5-TR criteria.
  • New or existing diagnosis of obsessive-compulsive disorder and/or posttraumatic stress disorder in the past 30 days, according to DSM-5-TR criteria, and which is unstable in the clinical judgment of the investigator.
  • New or existing primary diagnosis of anorexia nervosa, bulimia nervosa, or binge eating disorder in the past 3 months, according to DSM-5-TR criteria.
  • Clinically significant neurodevelopmental, neurocognitive, or personality disorder, according to DSM-5-TR criteria.
  • Moderate-High Risk of Suicide, according to the Columbia-Suicide Severity Rating Scale (C-SSRS) Screen Version - Recent (i.e., answers YES to Question 3 and NO to Question 6 (Moderate Risk), or YES to Question 4, 5, or 6 (High Risk)), or in the clinical judgement of the site investigator.
  • Lifetime history of a serious suicide attempt in the medical opinion of the site investigator.
  • Changes in treatment for pain in the past 2 months.
  • Treatment with electroconvulsive therapy, transcranial magnetic stimulation, ketamine, or esketamine in the past 30 days.
  • Currently diagnosed progressive neurological disease such as multiple sclerosis, chronic inflammatory demyelinating polyneuropathy, rapid progressive arachnoiditis, brain or spinal cord tumor, or severe/critical spinal stenosis (stenosis).
  • Cancer-related pain.
  • Diagnosis of malignancy other than basal cell carcinoma, or carcinoma in situ of the cervix within the past five years, to include life expectancy less than one year due to advanced malignancy.
  • Autoimmune-related pain.
  • Inadequately managed general medical condition, in the opinion of the site investigator.
  • Lifetime history of cerebral small vessel disease.
  • +7 more criteria
