Official Title: Ofatumumab in Children With Steroid- and Calcineurin-inhibitor-resistant Nephrotic Syndrome: a Double-blind Randomized, Controlled, Superiority Trial
Brief Summary:
Double-blind, two-parallel-arm, placebo-controlled randomized clinical trial testing the superiority of Ofatumumab versus placebo in the treatment of children with DR-INS. Participants will be stratified according to eGFR at enrollment.
Eligible participants will enter a 3-months run-in period, during which instructions on urine collection and dipstick readings will be carefully reviewed, compliance assessed and any immunosuppressive therapies withdrawn according to the following schemes:
After run-in period, children will be randomized to the intervention arm (Ofatumumab) or comparator arm (placebo). Randomization will be stratified by eGFR at randomization: ≥90 and <90 ml/min/1.73 m2.
All patients will be followed up to 12 months and they will leave the study at time of relapse.
Relapse will be defined as uPCR ≥2000 mg/g (≥200 mg/mmol) or ≥ 3+ protein on urine dipstick for 3 consecutive days.
