Description of intervention(s) / exposure
Treatment: Drugs - Eculizumab
Treatment: Drugs - Placebo

Experimental: Eculizumab - Biological/Vaccine: Eculizumab; Induction Period: Participants received eculizumab (900 milligrams [mg]) via intravenous (IV) infusion once a week (every 7 ± 2 days) for 4 weeks followed by eculizumab 1200 mg for the fifth dose (Week 4). This was followed by the Maintenance Period: Participants received eculizumab (1200 mg) via IV infusion every 2 weeks (every 14 ± 2 days) from the sixth dose (Week 6) onwards.

Placebo Comparator: Placebo - Placebo contains the same buffer components without the active ingredient. Induction Period: Participants received matching placebo (900 mg) via IV infusion once a week (every 7 ± 2 days) for 4 weeks, followed by matching placebo (1200 mg) for the fifth dose (Week 4). This was followed by the Maintenance Period: Participants received matching placebo (1200 mg) via IV infusion every 2 weeks (every 14 ± 2 days) from the sixth dose (Week 6) onwards.


Treatment: Drugs: Eculizumab
Induction Phase: 900 mg IV weekly for 4 weeks, followed by 1200 mg for the fifth dose; Maintenance Phase: 1200 mg IV every 2 weeks

Treatment: Drugs: Placebo
Induction Phase: matching placebo (900 mg) IV weekly for 4 weeks, followed by matching placebo (1200 mg) for the fifth dose; Maintenance Phase: matching placebo (1200 mg) IV every 2 weeks
