Clinical Trial Summary

Open-label, randomized, controlled trial due to value whether the monoclonal antibody rituximab is non-inferior to steroids in maintaining remission in juvenile forms of SDNS.

The investigators will enroll 30 pediatric patients affected by idiopathic nephrotic syndrome, who have been in treatment with steroids for at least one year. The lowest dose of drug required to maintain a stable remission will be between 0.4 and 0.7 mg/ kg/ day.

This trial provides an initial run-in phase of one month during wich remission will be achieved by means of a standard oral prednisone course. Once remission has been achieved children will be randomized in a parallel arm open label RCT to continue prednisone alone for one month (control) or to add a single intravenous infusion of rituximab (375 mg/m2 - intervention). Prednisone will be tapered in both arms after one month.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Three months proteinuria	To be considered non-inferior, rituximab will have to allow steroid withdrawal and maintain three-month proteinuria within a pre-specified non-inferiority margin of three times the levels among controls.	3 months
Secondary	Time-to-relapse mesaure	Risk of relapse of proteinuria and need for recovery of steroids, with survival analysis after withdrawal of steroids.	12 months
