Summary
Anti-CD20 monoclonal antibodies are emerging as the steroid-sparing therapy of choice for nephrotic syndrome.This Randomized Clinical Trial seeks to evaluate whether Rituximab biosimilar maintains drug-free disease remission in patients with steroid-dependent nephrotic syndrome for 12-24 months and verify its superiority vs. mycophenolate mofetil (1,200 mg/m2 orally in 2 daily doses). The investigators will compare the risk of relapse to test this hypothesis (primary outcome). Secondary objectives will include assessing short- and long-term side-effects and developing specific biomarkers of sensitivity to therapy. Patients will be recruited, treated and followed at IRCCS G Gaslini and IRCCS Bambino Gesù where laboratory studies will be performed at in-site facilities.

and child's assent given before any study-related procedure not part of the subject's
normal medical care, with the understanding that consent may be withdrawn by the
subject any time without prejudice to his or her future medical care.

Exclusion Criteria:

- Positivity to autoimmunity tests (ANA, nDNA, ANCA)

- Reduction of C3 levels.

patients between 2 and 17 years and with CKD-EPI Creatinine 2009 Equation for 18 years
old patients.
