Study Details

Study Description

Brief Summary

Anti-CD20 agent has been proposed as a rescue therapy for refractory nephrotic syndrome(NS) on the basis of favorable clinical observations. Yet the long-term effect on maintaining remission or the likelihood of becoming rituximab-dependent is unclear and the information on the safety profile of rituximab is limited. This trial was designed to investigate the safety and efficacy of Rituximab in children with refractory NS.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: steroid-resistant

Steroid-resistant group: n=27 , enroll all for treatment

Drug: Rituximab
Per dose: Rituximab 375 mg/m2 (max.500mg/day). efficacy monitored by CD19 cell count. If CD19 cells are not depleted, second or third doses are given at 2-3 weeks interval.
Other Names:
  • Mabthera
  • 2005110300291 (rituximab)

    steroid-responsive group: n=38

    Drug: Rituximab
    Per dose: Rituximab 375 mg/m2 (max.500mg/day). efficacy monitored by CD19 cell count. If CD19 cells are not depleted, second or third doses are given at 2-3 weeks interval.
    Other Names:

  • Placebo Comparator: steroid-dependent-placebo

    steroid-responsive group: n=23

    Drug: Placebo

    Outcome Measures

    Primary Outcome Measures

    1. The remission rate of steroid-resistant nephrotic syndrome patients after rituximab treatment [within 6 months from the initiation of treatment]

    2. The rate of maintaining remission in steroid-dependent nephrotic syndrome patients [within 6 months from the initiation of treatment versus placebo control]

    Eligibility Criteria

    Criteria

    Ages Eligible for Study:
    1 Year to 18 Years
    Sexes Eligible for Study:
    All
    Accepts Healthy Volunteers:
    No
    Inclusion Criteria:

    (A)steroid/calcineurin inhibitor resistant nephrotic syndrome

    1. steroid resistance: no remission after 4 weeks of daily oral corticosteroid (60mg/m2/day)

    2. calcineurin inhibitor resistance: no remission after 3 months of therapeutic dose administration of cyclosporine and/or tacrolimus

    3. no remission defined by persistent proteinuria of nephrotic range for the last 3 months

    4. post-transplant patients were included in the study

    (B)steroid-dependent nephrotic syndrome

    1. Steroid-dependent patients who had been on various known medications (such as corticosteroids, cyclophosphamide, chlorambucil, calcineurin inhibitors, levamisole ..) continuously for more than 2 years

    2. definition of dependency: more than two consecutive relapse events in 2 weeks after discontinuation of steroid or calcineurin inhibitor

    • no improvement in relapsing frequency with calcineurin inhibitor use

    • unable to continue with calcineurin inhibitor due to side effects

    • unable to continue with calcineurin inhibitor due to prolonged use (over 2 years)

    • other conditions in which the clinician considers difficult to control disease with steroids or calcineurin inhibitors only.

    Exclusion Criteria:
    • previous rituximab use

    • secondary nephrotic syndrome

    • estimated GFR <60mL/min/1.73m2 or under 50% of age-matched standard GFR

    • chronic or acute active infection (e.g. hepatitis B,C, herpes, varicella zoster)

    • prior live vaccine inoculation within 1 month (from the study enrollment)

    • cardiovascular diseases, pulmonary or pleural diseases

    • uncontrolled hypertension

    • leukocytopenia (absolute neutrophil count <1500/mm3) or thrombocytopenia (<75000/mm3)

    • pregnancy
