E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
test whether Ofatumumab is superior to Rituximab in maintaining oral drug-free disease remission (complete or partial remission) at 12 months |
testare se Ofatumumab sia superiore a Rituximab nel mantenimento di una remissione di malattia (completa o parziale) senza l¿utilizzo di farmaci per os a 12 mesi nei bambini affetti da INS dipendente da terapia steroidea e con CNI |
|
E.2.2 | Secondary objectives of the trial |
test whether Ofatumumab is superior to Rituximab in reduce the risk of relapse in a longer follow-up of 24 months in children with steroid and CNI-dependent INS |
testare se Ofatumumab sia superiore a Rituximab nella riduzione del rischio di recidiva in un periodo di follow up di 24 mesi nei bambini affetti da INS dipendente da terapia steroidea e con CNI. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
-To be in complete disease remission -Drug dependence: remission has to be maintained with both steroids and CNI steroid dependence is defined by two consecutive relapses during corticosteroid therapy or within 14 days of ceasing therapy. CNI (cyclosporine/tacrolimus) dependence is defined by presence of relapse at discontinuation. -Ability to provide consent and assent: parents’/guardian’s written informed consent, 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any study-related procedure not part of the subject’s normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to his or her future medical care. -Age between 2 and 18 years
|
-Remissione completa di malattia. -Dipendenza dai farmaci: la remissione di malattia deve essere mantenuta con entrambe le terapie, steroidea e con CNI. La corticodipendenza è definita come la presenza di due recidive consecutive in corso di terapia steroidea o entro 14 giorni dalla sua sospensione. La dipendenza da CNI (tacrolimus/ciclosporina) è definitica come la presenza di relapse in seguito alla sospensione. -Età compresa tra 2 e 18 anni. -Capacità di fornire un consenso/assenso: il consenso informato del genitore/tutore e l’assenso del bambino devono essere ottenuti prima di intraprendere qualsiasi procedura dello studio che non sia parte della normale assistenza del paziente e con la consapevolezza che tale consenso possa essere ritirato in qualsiasi momento, senza che ciò comporti un pregiudizio in merito al trattamento futuro del soggetto
