Condition(s) targeted: Nephrotic Syndrome

Intervention: Proleukin® (Drug)

Phase: Phase 1/Phase 2

Status: Completed

Sponsored by: Istituto Giannina Gaslini

Official(s) and/or principal investigator(s):
Gian Marco Ghiggeri, MD, Principal Investigator, Affiliation: Istituto Giannina Gaslini


The aim of the study is to design an open-label phase 1-2 trial to assess safety and clinical and immunologic effects of repeated administration of recombinant low dose IL2 (Proleukin) in 5 patients with idiopathic nephrotic syndrome unresponsive to drugs (steroids, calcineurin inhibitors, Rituximab), following the therapeutical scheme indicated for crioglobulinemic nephropathy: cycle1: IL2 1x106 /m2 s. c for 5 consecutive days cycle2: IL2 1. 5 x106 / m2 s. c for 5 consecutive days, starting from 3 weeks after the first cycle. cycle3: IL2 1. 5 x106 /m2 s. c for 5 consecutive days, starting from 6 weeks after the first cycle. Cycle 4: IL2 1. 5 x106 /m2 s. c for 5 consecutive days, starting from 9 weeks after the first cycle. Current therapy with steroids and calcineurin inhibitors (Prograf) will be maintained during the first cycle and progressively reduced during the subsequent cycles. The first cycle will be performed during hospitalization in the investigators Unit; subsequent cycles will be performed at nephrology outpatients. All laboratory values normally utilized in the follow up of patients affected by idiopathic nephrotic syndrome will be evaluated during the first week of treatment and at the end of the protocol, together with specific cellular values (Tregs, B cells, NK).

Adverse events


Minimum age: 2 Years. Maximum age: 18 Years. Gender(s): Both.


Inclusion Criteria:

- Drug resistance: persistence of proteinuria in nephrotic range after a cycle of

steroids of at least 3 months and an association with cyclosporine/tacrolimus for at least other 6 months

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study-related procedure not part of the subject's normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to his or her future medical care.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

- Histological pattern of minimal change disease, mesangial proliferation with IgM

deposits or focal segmental glomerulosclerosis Exclusion Criteria:

- Positivity to autoimmunity tests (ANA, dsDNA, ANCA).

- Reduction of C3 levels.

- Hystological pattern characterized by elements suggestive for congenital disease:

diffuse mesangial sclerosis without IgM deposits, cystic-like tubular dilatation, mitochondrial abnormalities evident on electron microscopy, IF suggestive for congenital collagen 4 disease.

- Histological pattern not suitable with INS in the pediatric age (membranous

glomerulonephritis, lupus nephritis, diffuse and/or localized vasculitis, amyloidosis)

- Homozygous or heterozygous mutations of to the 3 genes (NPHS1, NPHS2, WT1) whose

mutations are known to be responsible of almost 80% of familiar cases
