Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Crovalimab

Experimental: Crovalimab - Participants will be enrolled in three cohorts: \[1\] Naive Cohort - participants who have not been previously treated with complement inhibitor therapy; \[2\] Switch Cohort - participants who switch to crovalimab from another Complement Component 5 (C5) inhibitor and \[3\] C5 Single Nucleotide Polymorphism (C5 inhibitor) Cohort - participants with documented C5 polymorphism.


Treatment: Drugs: Crovalimab
Crovalimab will be administered at a dose of 1000 milligrams (mg) intravenous (IV) (for participants with body weight at least 40 (\>=) and up to 100 kilograms (kg) or 1500 mg IV (for participants with body weight \>=100kg) on Week 1 Day 1. On Week 1 Day 2 and on Weeks 2, 3 and 4, it will be administered at a dose of 340 mg subcutaneously (SC). On Week 5 and every 4 weeks (Q4W) thereafter, it will be administered at a dose of 680 mg SC (for participants with body weight \>= 40kg to \<100kg) or 1020 mg SC (for participants with body weight \>=100kg).
