Clinical Trial Summary

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).

Partial remission is defined as proteinuria reduction of 50% or greater from the presenting value and absolute uPCR between 200 and 2000 mg/g. for 3 consecutive days.	Change from baseline at 30, 60 and 180 days after first cycle (5 days)	No
Secondary	Tregs Levels		Immediately before first cycle and 30, 60 and 180 days after first cycle (5 days)	No
Secondary	Serum Creatinine		Change from baseline at 30, 60 and 180 days after first cycle (5 days)	No
Secondary	Adverse events		From day 1 to day 5 of each cycle. The study includes 5 cycles, each one lasting 5 days.	Yes
