Clinical Trial Summary

The main objective is to evaluate the effectiveness of Rituximab monotherapy versus steroid therapy on children with new-onset nephrotic syndrome within the 52-week follow-up.


Description:

Nephrotic syndrome(NS) -------the most common glomerular disease in children. Steroid, as the mainstream therapy for decades, many patients suffer from adverse effects of it, such as growth impacted, fat, and glaucoma.There is a urgent need for Steroid-sparing therapy. Rituximab, as a chemical monoclonal antibody against the cluster of differentiation antigen 20(CD20), has proved to be effective in patients with frequent-relapse/steroid-dependent NS. It has also been reported to be effective in six adult patients with new-onset NS. Rituximab mono-therapy in new-onset pediatric NS patients is still unclear.

Study Design


Intervention

Drug:
Rituximab
Rituximab dose: 4 doses of 375 mg/m2 rituximab at 1-week intervals( within +7 days), associated with trimethoprim-sulfamethoxazole(25-50 mg/kg/day orally twice per day, 3 days per week. If the patient is not allergic) for three months from the first rituximab dosing date(Day 1). Four doses of rituximab are necessary whether the patient achieves complete remission.
Steroid
Daily oral prednisone/prednisolone 2 mg/kg/d (maximum 60 mg/d) for 6 weeks followed by alternate day prednisone/prednisolone, 1.5 mg/kg (maximum of 50 mg), for other 6 weeks. Vitamin D and calcium(adjusted according to the blood calcium level) were administered for three months.

Outcome

Type Measure Description Time frame Safety issue
Primary Recurrence-free survival time(day) after first complete remission The time from complete remission to the first relapse during the whole 52-week follow-up in patients who achieve complete remission within 6 weeks. In order to evaluate the remission, all the participants will document their proteinuria. Relapse is defined by first-morning urine dipstick =3+ on three or more consecutive days, 24-h PCR=2.0g/g, or 24-h urine protein = 50mg/kg, with or without edema after complete remission(KDIGO 2021 Clinical Practice Guideline for the Management of Glomerular Diseases). Complete remission is defined by the first morning or 24h PCR = 0.2g/g (or negative or trace dipstick) on three or more consecutive occasions(KDIGO 2021 Clinical Practice Guideline for the Management of Glomerular Diseases). From complete remission to 52 weeks
Secondary Complete remission of nephrotic syndrome Complete remission is defined by the first morning or 24h PCR = 0.2g/g (or negative or trace dipstick) on three or more consecutive occasions (KDIGO 2021 Clinical Practice Guideline for the Management of Glomerular Diseases). It will be recorded as "1" when patients achieve complete remission, or as "0". From admission day to 6 weeks
Secondary Inefficiency of nephrotic syndrome Inefficiency is defined as patients still have nephrotic-range proteinuria(first-morning urine dipstick =3+dipstick, 24-h PCR=2.0g/g, or 24-h urine protein = 50mg/kg) after 6-week treatment. From admission day to 6 weeks
Secondary The time(day) to first complete remission The time(day) from the first medicine administration to complete remission within 6 weeks.Complete remission is defined by the first morning or 24h PCR = 0.2g/g (or negative or trace dipstick) on three or more consecutive occasions (KDIGO 2021 Clinical Practice Guideline for the Management of Glomerular Diseases). From admission day to 6 weeks
Secondary Relapse of nephrotic syndrome Relapse is defined as patients who have first-morning urine dipstick =3+ on three or more consecutive days, 24-h PCR=2.0g/g, or 24-h urine protein = 50mg/kg, with or without edema after complete remission(KDIGO 2021 Clinical Practice Guideline for the Management of Glomerular Diseases). It will be recorded as "1" when patients have a relapse, or as "0". From admission day to 52 weeks
Secondary Cumulative prednisone dosage of each individual (milligrams per kilogram per year) The total dosage of prednisone for each individual from the beginning to the end of the trial. From admission day to 52 weeks
