Cyclophosphamide Versus Mycophenolate Mofetil for the Treatment of Steroid-dependent Nephrotic Syndrome in Children (NEPHROMYCY)
|ClinicalTrials.gov Identifier: NCT01092962|
Recruitment Status : Completed
First Posted : March 25, 2010
Last Update Posted : March 26, 2015
Idiopathic nephrotic syndrome is steroid-sensitive in more than 90% of cases in children. However 60% of cases are steroid dependent and required treatment with immunosuppressive agent. Cyclophosphamide and ciclosporin are used for long time to reduce steroid dependency, but duration of these treatments should be restricted because of gonadotoxicity for cyclophosphamide and nephrotoxicity for ciclosporin.
Mycophenolate mofetil appears as an alternative treatment without gonadotoxicity and nephrotoxicity. However, contrary to cyclophosphamide, mycophenolate mofetil does not seem to have a residual action so that treatment must be maintained during months or years.
The aim of the study is to compare efficacy of cyclophosphamide and mycophenolate mofetil in steroid dependent nephrotic syndrome in children.
|Condition or disease||Intervention/treatment||Phase|
|Idiopathic Nephrotic Syndrome||Drug: Cyclophosphamide Drug: Mycophenolate mofetil||Phase 3|
Aim of the study: Comparison of efficacy of cyclophosphamide 148mg/kg in 12 weeks and mycophenolate mofetil 1200mg/m² during 18 months, in children with steroid dependent nephrotic syndrome.
The 70 patients will be recruited in the 26 centres of paediatric nephrology in France, included and randomized at the time of a relapse. They will receive the same steroid treatment in the 2 arms.
The primary point will be occurrence of a relapse during the 24 months of follow-up. Detection of relapse will be done by using dipsticks and confirm by biological dosages (albuminemia and proteinuria/CREATININURIA ratio). Clinical and biological check up will be done every 3 months during all the study.

- Relapse of nephrotic syndrome (defined by occurrence of proteinuria ≥ 0,25 g/mmol of CREATININURIA (or ≥ 2g/g) with hypoalbuminemia ≤ 30g/L AND/OR dipsticks >2+ during 3 days and proteinuria/CREATININURIA ratio ≥ 0,25 g/mmol) during 2 years. [ Time Frame: Months 1, 3, 6, 9, 12, 15, 18, 21, 24 ]

- Cumulative steroid dose received during the years before and under treatment [ Time Frame: Months 1, 3, 6, 9, 12, 15, 18, 21, 24 ]
- Comparison of growth data, during the year before and under treatment [ Time Frame: Months 1, 3, 6, 9, 12, 15, 18, 21, 24 ]
- Pharmacokinetics measurement of MPA and relation with efficacy in case of treatment with MMF [ Time Frame: One month after beginning MMF ]
