Estimated Enrollment: 12
Study Start Date: April 2012
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: GM-CSF Drug: Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF)
Participants will receive one dose of GM-CSF (5 µg/kg) by subcutaneous injection for ten (10) consecutive days. The first dose of GM-CSF will be administered by the subject or caregiver under the observation and direction of the study staff during the baseline visit. The subject or caregiver will administer subsequent injections at home.
Other Name: LEUKINE® (sargramostim)

Detailed Description:
Twelve patients aged 18-80 with symptomatic generalized autoimmune MG that are not being treated with medication that suppresses their immune system, other than prednisone, will enter the study at UIC over a two year period. The study will involve a screening visit and visits at baseline and at days 5, 15, 30, 45, 60, 90, and 120. The study drug, Leukine (GM-CFS), is given by injection. Subjects will give themselves one dose of GM-CSF every day for 10 days. Study visits will include muscle testing, immunologic studies and quality-of-life studies.

Criteria

Inclusion Criteria:

  • Must be between 18 and 80 years of age
