Experimental Treatment
Group I: EculizumabExperimental Treatment1 Intervention
All participants will receive open-label eculizumab by intravenous infusion during the Primary Treatment Period, starting on Day 1 and for a total of 52/53 weeks. The dosing regimen will be based on the participant's body weight. As body weight changes during the study, the participant's weight cohort and dose may change accordingly. After completing the 52/53-week Primary Treatment Period, participants may continue receiving eculizumab in the Extension Treatment Period for 104 weeks.
