This study will look at the effect of the PRIMA device on fibromyalgia symptoms. Recruitment continues through June, 2010. The next post has more reader-friendly information on how the device works. While the research is being conducted by the University of Virginia, one need not go there to participate.

Here's the description of the study:

Central pain networks in the brain are dysregulated in persons with fibromyalgia (FM). Thus, the investigators propose that cranial electrical stimulation (CES) that works on the brain may ameliorate symptoms of FM by interacting with the central pain networks. The specific aims of this randomized, controlled, three-group pilot study design are to: (1) determine differences in pain over time between the active CES, sham device, and usual care (UC) groups; (2) explore differences in brain activity in pain processing regions (i.e., cingulate, insula, prefrontal and somatosensory cortices, amygdala, and thalamus) between the active CES, sham device, and UC groups in a subset of 12 participants (6 in each device group); (3) determine the effects of CES on other symptoms (fatigue, sleep disturbances, depression, perceived stress) and functional status, and blood pressure over time between the active CES, sham device, and UC groups; and (4) determine the amount of influence that selected psychological factors (negative affect, catastrophizing, and other personality characteristics) have on group differences in pain, other symptoms, functional status, and brain activity.

More info on trial

Fibromyalgia Pain Relief with Portable Neuromodulation Device

RELIEF clinical trial will evaluate safety and determine the effectiveness of the PRIMA device to significantly reduce fibromyalgia pain.


Device: The Model 801 PRIMA is a portable unit that is the size of a cassette player with attaching headphones.

Manufacturer and Sponsor: Fralex Therapeutics, Inc. of Toronto, Ontario, Canada

FDA Status: The FDA has not approved the PRIMA device for any use in the United States. It is being tested in a pivitol (Phase III) trial under an Investigational Device Exemption (IDE) from the FDA.

European Status: The PRIMA device has been granted CE marketing, which allows the sale and distribution of the product in Europe.

Basic Info: During the past few years, pain researchers have explored the use of magnetic fields or pulses, as well as small currents that are applied to the brain’s outer cortex to alter the function of the cells beneath. Unlike taking pain medications, these devices have the potential to favorably modify brain function while ideally minimizing systemic side effects. Transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), and the complex neural pulse (CNP) are three such therapies being investigated in this category for the treatment of fibromyalgia pain. The PRIMA device is the first to employ CNP and differs from the other two types of technology in the following important ways:

•It does not produce an electric current in the manner that tDCS works (i.e., no electrons pass through the tissues).
•The magnetic field generated by the PRIMA device is much lower powered than TMS, which allows the generator to be a portable home unit. The higher powered TMS units require that patients attend a clinical setting for treatment due to the large size of the generator (an inconvenience for patients).
•Magnetic field strength produced by the device is less than the industry limits for electric hair dryers.
•The shape of the wave-forms and pulsing frequency used by the PRIMA device in this study are custom designed to interact specifically with the brain centers involved for a particular condition. Separate wave-forms have been designed for pain, depression and anxiety. In other words, CNP is not a "one-shoe-fits-all" type of technology.
Patients simply put the headsets on for 40 minutes twice a day and turn on the generator unit (the size of a portable cassette player) to receive their therapy. The headset rests above the ears, so patients may listen to music, watch TV, or engage in other sedentary activities while receiving therapy. The PRIMA device does not make any noise, emit light or produce any detectible sensation. This makes it comfortable to wear for the 40-minute treatment session and also means that it is easy to blindly test the function of the device against an identical one that has been electronically disabled (e.g., to provide a placebo or sham model).

Recruiting for Phase III Trial: A 12-week placebo-controlled study is ongoing to primarily determine the effectiveness of the PRIMA device to reduce fibromyalgia pain. Its effect on mood, sleep quality, and physical functioning will also be assessed. Twelve cities in the United States and four in Canada are recruiting a total of 200 fibromyalgia patients for the study. Participants must visit the trial center seven times during the study and they have a 50% chance of receiving the "sham" or disabled device.

Previous Testing: Two small reports have been published in the medical journals on the potential for the PRIMA device to relieve pain in fibromyalgia.1,2 No side effects occurred, although the number of patients studied was small and trial durations were short. The PRIMA device has already been approved for marketing in Europe because the European approval process focuses on safety (almost 400 people were involved in the safety testing). However, Fralex plans to market the device in Europe after the ongoing Phase III trials in the United States and Canada are completed.

Study Criteria (key requirements):

•Must meet the diagnostic criteria for fibromyalgia
•Male or female, 18 years or older
•Must be willing to discontinue all medications for pain, mood, and sleep disorders except for acetaminophen and cardiac aspirin (up to 325 mg per day)
•Cannot have any of the following:
◦autoimmune or inflammatory disease

◦major depressive disorder and other psychiatric conditions

◦history or current treatment for cancer, seizure disorder, or migraine

◦hearing aids, pacemakers, or metal implants above mid-torso (except dental work)
