Description of intervention(s) / exposure
Treatment: Other - Ravulizumab
Treatment: Other - Eculizumab

Experimental: Ravulizumab - On Day 1, participants received weight-based doses of ravulizumab ranging from 2400 to 3000 milligrams (mg). Thereafter, weight-based doses of ravulizumab ranging from 3000 to 3600 mg were administered on Days 15, 71, and 127.

After completion of the 26-week Primary Evaluation Period, participants had the opportunity to enter the Extension Period, wherein participants will receive weight-based doses of ravulizumab for up to 4 years.

Active comparator: Eculizumab - Participants received 900 mg of eculizumab every 2 weeks (q2w) for 26 weeks.

After completion of the 26-week Primary Evaluation Period, participants had the opportunity to enter the Extension Period, wherein participants will receive weight-based doses of ravulizumab for up to 4 years.


Treatment: Other: Ravulizumab
All treatments were given as intravenous (IV) infusions. For participants weighing =40 to \<60 kilograms (kg): 2400 mg was given as a single loading dose, followed by 3000 mg as maintenance dose. For participants weighing =60 to \<100 kg: 2700 mg was given as a loading dose, followed by 3300 mg as maintenance dose. For participants weighing =100 kg: 3000 mg was given as a loading dose, followed by 3600 mg as maintenance dose.

Treatment: Other: Eculizumab
All treatments were given as IV infusions. Participants received 900 mg of eculizumab q2w.
