Clinical Trial 11571

Colorado Springs, CO 80907


Study Summary:

Your teenager may have fibromyalgia.
Does your daughter or son complain of pain or stiffness? Does she or he have a hard time falling asleep at night or getting out of bed in the morning? Is she or he tired all the time? If so, your teenager may have juvenile fibromyalgia and may be eligible to participate in an Adolescent Primary Fibromyalgia clinical research study called MyFi.

About the study
The main purpose of the MyFi clinical research study is to find out if the study drug called milnacipran is safe and effective in helping young people manage their fibromyalgia.

  • Researchers want to learn more about fibromyalgia and how it affects adolescents
  • Researchers want to learn more about treatment options that may benefit adolescents with fibromyalgia
  • About 300 teenagers will participate in this study nationwide
  • Milnacipran has been approved by the U.S. Food and Drug Administration (FDA) in adults for the management of fibromyalgia. However, the use of milnacipran in this study is experimental because it has not been approved by the U.S. FDA for use in pediatric (children and adolescents) patients.

About the study drug
Milnacipran falls into a class of drugs known as serotonin and norepinephrine reuptake inhibitors (SNRIs).
  • Serotonin and norepinephrine are substances made by the brain that influence how the brain sends messages to the body and in turn how the body responds to pain
  • Researchers think that the study drug may help serotonin and norepinephrine to work better on the central nervous system, which serves as the body’s main message “processing center"

Who can participate?
To be eligible to participate in the MyFi study, your child must be 13 to 17 years old and:
  • Receive a diagnosis at the first study visit or already have a diagnosis of fibromyalgia
  • Have had unsatisfactory results after trying other non-drug treatments for fibromyalgia (e.g., diet, exercise, acupuncture)
  • Be willing to take a drug screening test
  • Be willing to discontinue certain medications, if required
  • If female, be willing to take a pregnancy test

Additional study requirements can be reviewed with site study staff.
