Study to Assess Mechanisms in Peripheral Tissue Innervation for Fibromyalgia

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified December 2010 by Albany Medical College.

The purpose of this study is to examine the characteristics of the nerves and the small veins in the skin of people with fibromyalgia. The investigators will then use this information to identify possible processes in the skin that may help explain why some people feel pain relief with the study drug (duloxetine) and others do not.

Duloxetine affects certain chemicals in the brain called neurotransmitters. An abnormality in these chemicals is thought to be related to fibromyalgia. Duloxetine is a selective serotonin and norepinephrine reuptake inhibitor (SNRI), similar to some drugs used for the treatment of depression. Duloxetine is approved for sale in the United States by the Food and Drug Administration (FDA) for the treatment of fibromyalgia.

Condition Intervention
Drug: Duloxetine
Procedure: Skin biopsy

Study Type: Interventional
Study Design: Allocation: Non-Randomized

Further study details as provided by Albany Medical College:

Primary Outcome Measures:
  • Efficacy of duloxetine will be determined by neurological and pain assessments. [ Time Frame: 9 weeks ]
    Patients will be evaluated prior to being started on duloxetine and again at eight weeks. We will use data from VAS scores, sleep diaries and quantative sensory testing.

Estimated Enrollment: 30
Study Start Date: December 2010
Estimated Study Completion Date: December 2012
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Duloxetine
    Subjects will be titrated onto Duloxetine over one week by taking 30 mg every day for seven days. Week 2 the subject will begin to take 60 mg per day until the end of the study. If the subject wishes to stop taking Duloxetine, she will be given 30 mg per day for one week for down titration.
    Other Name: Cymbalta
    Procedure: Skin biopsy
    3 mm skin biopsies will be obtained from the dominant trapezius and the glabrous hypothenar area of the hand
    Other Name: Punch biopsy
