Study Arms:
- Cohort 1 (Type: EXPERIMENTAL): During the Treatment Period, participants were administered ravulizumab 1400 milligram (mg) on Day 1, ravulizumab 1000 mg on Day 15 and Day 29, and then ravulizumab 1000 mg every 4 weeks for 7 doses.~In the Extension Period, participants initially continued to receive their dose. During the second year of the study, participants were administered weight-based doses of ravulizumab every 8 weeks for up to 5 years: 3000 mg for participants weighing 40 to less than 60 kilograms (kg), 3300 mg for participants weighing 60 to less than 100 kg, and 3600 mg for participants weighing 100 kg or more.
- Cohort 2 (Type: EXPERIMENTAL): During the Treatment Period, participants were administered ravulizumab 2000 mg on Day 1, ravulizumab 1600 mg on Day 22 and Day 43, and then ravulizumab 1600 mg every 6 weeks for 4 doses.~In the Extension Period, participants initially continued to receive their dose. During the second year of the study, participants were administered weight-based doses of ravulizumab every 8 weeks for up to 5 years: 3000 mg for participants weighing 40 to less than 60 kg, 3300 mg for participants weighing 60 to less than 100 kg, and 3600 mg for participants weighing 100 kg or more.
- Cohort 3 (Type: EXPERIMENTAL): During the Treatment Period, participants were administered ravulizumab 1600 mg on Day 1 and Day 15, ravulizumab 2400 mg on Day 29, and then ravulizumab 2400 mg every 8 weeks for 3 doses.~In the Extension Period, participants initially continued to receive their dose. During the second year of the study, participants were administered weight-based doses of ravulizumab every 8 weeks for up to 5 years: 3000 mg for participants weighing 40 to less than 60 kg, 3300 mg for participants weighing 60 to less than 100 kg, and 3600 mg for participants weighing 100 kg or more.
- Cohort 4 (Type: EXPERIMENTAL): During the Treatment Period, participants were administered ravulizumab 3000 mg on Day 1, ravulizumab 5400 mg on Day 29, and then ravulizumab 5400 mg every 12 weeks for 2 doses.~During the Extension Period, participants were administered ravulizumab 5400 mg every 12 weeks for up to 5 years.
