Study Description

Brief Summary:

Open-label, two-parallel-arm, controlled randomized clinical trial testing the superiority of Ofatumumab over Rituximab in maintaining steroid- and calcineurin-inhibitor-free disease remission in SD-INS.

Eligible participants will enter a 1-month run-in period, during which instruction on urine collection and dipstick readings will be carefully reviewed, compliance assessed, and therapy with RAS inhibitors withdrawn and, in hypertensive children replaced by other anti-hypertensive drug.

After run-in period, children will be randomized to either the intervention arm (Ofatumumab) or the comparator arm (Rituximab).

After infusion of intervention or comparator, steroids will be maintained at initial dose for 30 days and then tapered off by 0.3 mg/kg per week until complete withdrawal.

One week after the steroid withdrawal calcineurin inhibitors will be decreased by 50% and withdrawn within 2 additional weeks.

All patients will be followed for up to 24 months. In case of relapses during the study (see outcome section for definition) patients will be treated with 60 mg/m2of prednisone p.o. in order to achieve remission. At remission, patients will be treated with another infusion of either Oftumumab or Rituximab, according to the initial randomization.

After infusion of intervention or comparator, steroids will be maintained at initial dose for 30 days and then tapered off by 0.3 mg/kg per week until complete withdrawal.

One week after the steroid withdrawal calcineurin-inhibitors will be decreased by 50% and withdrawn within 2 additional weeks. This strategy will be repeated to treat full relapses during the study.
