Clinical Trial Summary

In this pilot study, the PI proposes to include 20 African American participants with Fibromyalgia to explore the effect of r TMS on pain and depressive symptoms.

Description:

In this pilot study, the PI proposes to include 20 African American participants with Fibromyalgia to explore the effect of r TMS on pain and depressive symptoms. The focus on African Americans is due to the mandate from the funding source (internal), as well as possible higher prevalence of FM in AA women. If recruitment is slow, the PI proposes to open up the study to other groups. Twenty subjects will be randomized to either sham or active TMS condition. Inclusion/exclusion criteria are well thought out and seem appropriate. mTreatments will be administered at IOP 5 times/wk with each session lasting 20 minutes. Pain intensity and unpleasantness will be measured pre and post each TMS session using three different pain evaluation paradigms. GCRC resource is mainly requested for two blood draws pre and post first TMS session. The blood samples will be used to measure inflammatory cytokines IL-1, IL-6, AND IL-8. The main aim is to ascertain feasibility of the study and secondary aim is to gather information on variability in response for power analysis for future larger study. The introduction and rationale (including pain evaluation, and methods relating to TMS) are clearly presented. Use of GCRC resources seem appropriate.

Intervention

Device:
• Active TMS
Active TMS uses the active TMS coil to stimulate the cortical area of interest. Active TMS involves 80 trains x 15 sec = 4000 pulses per session, 5 x per week= 20,000 pulses per week, x 2 weeks = 40,000 pulses.
• Sham TMS
Sham TMS uses the same stimulation frequency as the Active TMS but uses the Sham TMS coil instead to prevent actual stimulation from occurring (chosen as a priori stimulation based on studies showing antidepressant and anti-nociceptive effects): 10 Hertz - Pulse train duration (on time) 5 seconds, Power (intensity) level 120% of stored motor threshold, Inter-train interval (off time) 10 seconds (15 second cycle time). Additionally, stimulation-train duration and inter-stimulus intervals were determined such that they are in compliance with current published rTMS safety guidelines.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Average Pain	To assess each participant's average Pain in the past 24 hours, The Brief Pain Inventory (BPI)-short form will be administered. The BPI rapidly assesses the severity of pain and its impact on functioning and has been widely used in both research and clinical settings. Participants rate their average pain in the past 24 hours using a 0-10 numerical rating scale, where 0=no pain and 10=extreme pain.	Baseline, After Week 1 of Treatment, After Week 2 of Treatment, One week Post Treatment follow up, and Two week post treatment follow up
Primary	THE FIBROMYALGIA IMPACT QUESTIONNAIRE (FIQ)-Modified	To assess the impact of fibromyalgia on each participant's function, the FIQ-modified (2002) version will be administered before each study visit. The FIQ-modified (2002) version assesses the following symptoms; physical Impairment, well-being, pain, fatigue, rested, stiffness, anxiety, and depression within the past 24 hours. Each symptom scale ranges from 0 to 10. For example, 0=no pain and 10=extreme pain, 0=not fatigued and 10=extremely fatigued.; The final score is the total score which ranges from 0 to 80. Higher scores indicate greater impact of fibromyalgia on functioning.	Baseline, After Week 1 of Treatment, After Week 2 of Treatment, One week Post Treatment follow up, and Two week post treatment follow up
Primary	THE HAMILTON DEPRESSION RATING SCALE (HRDS)	To assess each participant's level of depression, the HRDS will be administered. The HRDS is a 17-item clinician-rated scale that is designed to evaluate depressed mood, vegetative and cognitive symptoms of depression, and comorbid anxiety symptoms. Eight items are scored on a 5-point scale, ranging from 0-4, where 0=not present and 4=severe. Nine items are scored from 0-2, where 0=None, 1=Mild, and 2=Severe. The final, total score ranges from 0-52. Scores in the range of 0-7 are considered as being normal, 8-16 suggest mild depression, 17-23 moderate depression, and scores over 24 are indicative of severe depression.	Baseline, After Week 1 of Treatment, After Week 2 of Treatment, One week Post Treatment follow up, and Two week post treatment follow up
