NCT ID: NCT04689074 Completed - Clinical trials for Autosomal Dominant Polycystic Kidney Disease (ADPKD)

Establishment of the Human Intestinal and Salivary Microbiota Biobank - Kidney Diseases

BIOMIS-Nefro
Start date: February 3, 2021
Phase:
Study type: Observational

This is a prospective, clinical, multicentre study aimed to collect biological samples and study microbiota from subjects suffering from chronic kidney disease and from healthy volunteers. Microbiota is a complex consortium of microorganisms, located at the mucosal level (in particular intestinal, oral and vaginal) having a key role in human health and in the onset of several diseases. Microbiota alterations have been found in several diseases (gastrointestinal, metabolic, renal, oncological, gynaecological). The study will allow to: - Provide biological samples (faeces, saliva, blood, urine) from healthy volunteers and patients suffering from chronic renal diseases to the first Italian microbiota biobank; - Study microorganisms using different in vitro and in vivo techniques; - Study the link between the microbiota and the disease. This study is part of the BIOMIS project (Project Code: ARS01_01220), presented as part of the "Avviso per la presentazione di progetti di ricerca industriale e sviluppo sperimentale nelle 12 aree di specializzazione individuate dal PNR 2015-2020" and admitted to funding under the National Operational Program "Ricerca e Innovazione" 2014-2020 by directorial decree of MIUR - Department for Higher Education and Research - n. 2298 of 12 September 2018. BIOMIS includes several clinical studies that enrol patients with different pathologies to collect and store biological samples and study microbiota.

Start date: December 10, 2020
Phase: Phase 2
Study type: Interventional

NCT ID: NCT04662723 Recruiting - Glomerulonephritis Clinical Trials

Multicentre Clinical Study to Evaluate the Effect of Personalized Therapy on Patients With Immunoglobulin A Nephropathy.

CLIgAN
Start date: May 1, 2023
Phase: Phase 4
Study type: Interventional

Idiopathic immunoglobulin A nephropathy (IgAN) is the most common biopsy-proven glomerulonephritis in the world. Approximately 40% of IgAN patients reach end-stage kidney disease (ESKD) 20 years after their kidney biopsy. The high prevalence of ESKD suggests the need to move from a generalized therapy for all patients to personalized therapy. Many RCTs have been conducted stratifying patients based on the laboratory findings (serum creatinine, eGFR and daily proteinuria). In contrast, data from the kidney biopsy has been used only for clinical diagnosis. Therefore, IgAN patients with active or chronic renal lesions have not been equally distributed in experimental and control arms of the randomized clinical trials (RCTs) Our clinical study of IgAN (CLIgAN) is a multicentre, prospective, controlled and open-label randomized clinical trial based on patients' stratification at the time of their kidney biopsy. The investigators will consider, first, the type of renal lesions followed by the serum creatinine values, eGFR and proteinuria. IgAN patients with active renal lesions (n=132) will be enrolled in the first RCT (ACIgAN) in which they will receive corticosteroids (pulse therapy) plus oral corticosteroids combined with RASB or RASB followed by oral corticosteroids. IgAN patients with chronic or moderate renal lesions at high or very high risk of chronic renal disease (n=294) will be enrolled in the second RCT (CHRONIgAN) in which they will receive the SGLT2 inhibitor combined with RASB compared with RASB combined with oral corticosteroids. Using this approach, the investigators hypothesize that patients could receive personalized therapy based on renal lesions to ensure that the right drug gets to the right patient at the right time. Recently, we developed a Clinical Decision Support System (CDSS) tool using artificial intelligence (artificial neural networks) to identify IgAN patients at high risk of developing ESKD. The IgAN tool (DialCheck) was validated in a retrospective cohort of IgAN patients but not in a prospective clinical study. The investigators propose to measure the power of the DiaCheck tool in patients enrolled in both RCTs to determine whether personalized therapy can slow the decline of the renal function to delay the ESKD. The CLIgAN study also includes a cutting-edge molecular study for precision therapy (PRECIgAN).

NCT ID: NCT04578834 Active, not recruiting - IgA Nephropathy Clinical Trials

Study of Efficacy and Safety of LNP023 in Primary IgA Nephropathy Patients

APPLAUSE-IgAN
Start date: January 25, 2021
Phase: Phase 3

NCT ID: NCT04557462 Recruiting - Clinical trials for Primary IgA Nephropathy

A Rollover Extension Program (REP) to Evaluate the Long-term Safety and Tolerability of Open Label Iptacopan/LNP023 in Participants With Primary IgA Nephropathy

Start date: September 20, 2021
Phase: Phase 3
Study type: Interventional

The purpose of this study is to evaluate the long-term safety and tolerability, of open label iptacopan in primary IgA nephropathy participants who have completed either the CLNP023X2203 or CLNP023A2301 clinical trials. The open-label design of the current study is appropriate to provide study participants the opportunity to receive treatment with iptacopan until marketing authorizations are received and the drug product becomes commercially available while enabling collection of long-term safety and tolerability data for the investigational drug. Furthermore efficacy assessments conducted every 6 months will afford the opportunity to evaluate the clinical effects of iptacopan on long-term disease progression.

Efficacy and Safety in Patients With Primary IgA Nephropathy Who Have Completed Study Nef-301 (Nefigard-OLE)

Nefigard-OLE
Start date: November 14, 2020
Phase: Phase 3
Study type: Interventional

This is a Phase 3b, multicenter, open-label extension (OLE) study to evaluate the efficacy and safety of Nefecon treatment in patients with IgAN who have completed the Phase 3 Study Nef-301 and continue to be treated with a stable dose of RAS inhibitor therapy (ACEIs and/or ARBs). Patients who previously received Nefecon in Study Nef-301 will receive retreatment, whereas patients who previously received placebo in Study Nef-301 will be treatment naïve to Nefecon.
