METHODS FOR TREATING COMPLEMENT-ASSOCIATED DISORDERS
The present disclosure relates to, inter alia, compositions containing an inhibitor of human complement and use of the compositions in methods for treating or preventing complement-associated disorders. In some embodiments, the inhibitor is chronically administered to patients. In some embodiments, the inhibitor is administered to a patient in an amount and with a frequency to maintain systemic complement inhibition and prevent breakthrough. In some embodiments, the compositions contain an antibody, or antigen-binding fragment thereof, that binds to a human complement component C5 protein or a fragment of the protein such as C5a or C5b.

94 . A method for treating myasthenia gravis (MG) in an anti-AChR antibody positive patient, the method comprising administering eculizumab to a patient in need thereof in an amount effective to treat MG in the patient; wherein the administration schedule of eculizumab comprises: administering at least 600 mg of eculizumab once per week for the first four weeks of treatment; and, beginning one week after the initial four-week treatment, administering a maintenance dose of at least 900 mg of eculizumab every two weeks.
95 . The method of claim 94 , wherein the eculizumab is administered to the patient in an amount and with a frequency to maintain at least 50 μg of eculizumab per milliliter of the patient's blood.
96 . The method of claim 94 , wherein the eculizumab is administered to the patient in an amount and with a frequency to maintain at least 100 μg of eculizumab per milliliter of the patient's blood.
97 . The method of claim 94 , wherein the patient exhibits a substantial improvement in at least two symptoms of MG during the first four weeks of treatment.
98 . The method of claim 94 , wherein the maintenance dose of eculizumab is administered every two weeks until the patient's MG is in remission.
99 . A method for treating myasthenia gravis (MG) in an anti-AChR antibody positive patient, the method comprising administering eculizumab to a patient in need thereof in an amount effective to treat MG in the patient; wherein the eculizumab is intravenously administered to the patient under the following schedule:
900 mg of eculizumab once per week for four consecutive weeks;
1200 mg of eculizumab on the fifth week; and
1200 mg of eculizumab every two weeks thereafter.
100 . The method of claim 99 , wherein the eculizumab is administered to the patient in an amount and with a frequency to maintain at least 50 μg of eculizumab per milliliter of the patient's blood.
101 . The method of claim 99 , wherein the eculizumab is administered to the patient in an amount and with a frequency to maintain at least 100 μg of eculizumab per milliliter of the patient's blood.
102 . The method of claim 99 , wherein the patient exhibits a substantial improvement in at least two symptoms of MG during the first four weeks of treatment.
103 . The method of claim 99 , wherein the maintenance dose of eculizumab is administered every two weeks until the patient's MG is in remission.
