E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To evaluate the effect of corticosteroids combined with RASBs in IgAN patients with active renal lesions (ACIgAN) versus RASBs alone to determine whether the renal damage is reversed by corticosteroids; • To evaluate the effect of SGLT2i (Dapagliflozin) combined with RASBs versus RASBs alone in patients with chronic renal lesions (CHRONIgAN) and in patients with moderate renal lesions at high or very high risk of CKD to determine whether a delay of the ESKD onset is achieved. |
• Valutare l’effetto dei corticosteroidi associati con RASB rispetto alla terapia con soli RASB, in pazienti IgAN con lesioni renali attive (ACIgAN), per valutare se il paziente ha un effetto benefico con i corticosteroidi. • Valutare l’effetto dell’inibitore del co-trasportatore renale del sodio-glucosio di tipo 2 (SGLT2i), Dapagliflozina, associato con RASB rispetto alla terapia con soli RASB, in pazienti con lesioni renali croniche (CHRONIgAN) ed in pazienti con lesioni renali moderate con rischio alto o molto alto di malattia renale cronica (CKD), per valutare se si ottiene un ritardo nell’insorgenza della insufficienza renale cronica (ESKD). |
|
E.2.2 | Secondary objectives of the trial |
• after the prediction of ESKD through our IgAN CDSS tool (DialCheck), to determine whether personalized therapy delays the impairment of the renal function; • a cutting edge-molecular study will be conducted on a small cohort of enrolled IgAN patients with active or chronic/moderate renal lesions to evaluate the effect of precision therapy (BIO-D). |
• Valutare se la terapia personalizzata ritarda il danno renale e monitorare il decorso della malattia, mediante l’utilizzo del tool CDSS (Sistema di supporto alla decisione clinica) DialCheck. • Sarà condotto uno studio molecolare all’avanguardia su una piccola coorte di pazienti IgAN arruolati con lesioni renali attive o croniche/moderate per valutare l’effetto della terapia di precisione (BIO-D). |

Farmacogenomica Versione: 1.0 Data: 08/02/2022 Titolo: Analisi molecolari su campioni biologici per la terapia di precisione in IgAN (BIO-D) Obiettivi: • integrare i risultati trascrittomici ottenuti da tutti e tre i compartimenti (sangue, rene e urina) nello stesso paziente, al momento della biopsia renale e poi durante il follow-up, per valutare il beneficio dei corticosteroidi e il beneficio di Dapagliflozin in combinazione con RASB vs RASB nei pazienti con lesioni renali attive e in pazienti con lesioni renali croniche o moderate. • identificare biomarcatori specifici che potrebbero essere sfruttati per l'identificazione di nuovi bersagli terapeutici e il beneficio di una terapia personalizzata.
