Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 45 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase III, Multicenter, Single-Arm Study Evaluating the Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of Crovalimab in Pediatric Patients With Atypical Hemolytic Uremic Syndrome (aHUS)
Actual Study Start Date : November 17, 2021
Estimated Primary Completion Date : December 12, 2025
Estimated Study Completion Date : September 16, 2029


Arm Intervention/treatment
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 C5 inhibitor and [3] Pretreated Cohort (includes C5 SNP (Single Nucleotide Polymorphism) participants) - participants who received treatment with another C5 inhibitor and subsequently discontinued it.
Drug: Crovalimab
Crovalimab will be administered at a dose of 1000 mg intravenously (IV) (for participants weighing 40 to <100 kg) or 1500 mg IV (for participants weighing >=100 kg) on Week 1 Day 1. On Week 1 Day 2 and on Weeks 2, 3 and 4, crovalimab will be administered at a dose of 340 mg subcutaneously (SC). On Week 5 and Q4W thereafter, it will be administered at a dose of 680 mg SC (for participants weighing 40 to <100 kg) or 1020 mg SC (for participants weighing >=100 kg). Enrollment of participants weighing <40 kg will be staggered using two weight-based dose confirmation groups (Group 1 participants weighing >=20 kg to <40 kg, followed by Group 2 participants weighing >=5 kg to <20 kg). All participants will receive an initial IV loading dose, which will be followed by SC dosing at either Q2W or Q4W intervals (depending on body weight), until study completion.
