Treatment: Drugs - Placebo

Experimental: Eculizumab - Biological/Vaccine: Eculizumab; Induction phase: 3 vials of study drug (equivalent to 900 mg of eculizumab) weekly for 4 doses (every 7 days ± 2 days) followed by 4 vials of study drug (equivalent to 1200 mg of eculizumab) 1 week later for the fifth dose (Week 4); Maintenance phase: 4 vials of study drug (equivalent to 1200 mg of eculizumab) every 2 weeks (14 days ± 2 days) from the fifth dose onwards (Week 6 through Week 26).

Placebo Comparator: Placebo - Placebo contains the same buffer components without the active ingredient; Induction phase: 3 vials of study drug (placebo) weekly for 4 doses (every 7 days ± 2 days) followed by 4 vials of study drug (placebo) 1 week later for the fifth dose (Week 4); Maintenance phase: 4 vials of study drug (placebo) every 2 weeks (14 days ± 2 days) from the fifth dose onwards (Week 6 through Week 26).
