Primary Outcome Measures:
  • Change in MG severity [ Time Frame: Change from Baseline to Week 12 ]
    Change will be measured using the Quantitative Myasthenia Gravis (QMG) Score for Disease severity. The QMG is a validated clinical composite scale.

Secondary Outcome Measures:
  • Efficacy of SCIg in MG [ Time Frame: Change from Baseline to Week 12 ]
    Composite measure of scores from measurement scales including Myasthenia Gravis-specific Activities of Daily Living scale (MG-ADL), MG Quality of Life (QOL)-15, MG composite score, and Treatment Satisfaction Questionnaire for Medication (TSQM)

  • Safety and tolerability of SCIg in people with MG [ Time Frame: Change from Week -12 to Week 12 ]
    Measure safety profile between intravenous and subcutaneous treatment phases as measured by changes in routine safety laboratory tests. Lab tests used to determine outcome include CBC, differential and comprehensive chemistry profile.

  • Number of Participants with Serious and Non-Serious Adverse Events [ Time Frame: Up to 16 Weeks ]
    Safety of SCIg in MG patients measured according to adverse event experienced by trial participants

  • Effect of SCIg on IgG antibody levels [ Time Frame: Change from Week -12 to Week 12 ]
    Measure IgG level between intravenous and subcutaneous study phases

Estimated Enrollment: 25
Actual Study Start Date: January 2015
Estimated Study Completion Date: December 2018
Estimated Primary Completion Date: December 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Hizentra
Hizentra is a subcutaneous (under the skin) immunoglobin (SCIg). Participants will receive weekly Hizentra. Dose and rate depend on the visit and how each participant tolerates the drug. Max flow rate not to exceed 100 mL per hour.
Other Name: Immune Globulin Subcutaneous (Human), 20% Liquid

Detailed Description:

Myasthenia gravis (MG) is a rare autoimmune disorder which causes the muscles to become weak because the immune system attacks the connection between the nerves and the muscles.

Hizentra is a subcutaneous (under the skin) immunoglobin (SCIg). An immunoglobin is a blood protein. Hizentra is being studied for the treatment of patients with MG. Hizentra is administered by an injection into the skin through a portable infusion pump, which may be easier for patients to administer than the current treatments.

Participants will be asked to complete 9 clinic visits and 3 telephone calls. It could take up to 30 weeks to complete all study visits.
