Primary IgA Nephropathy

The purpose of this study is to evaluate the efficacy, safety, and pharmacokinetics of sefaxersen (RO7434656), a novel Antisense Oligonucleotide (ASO) therapy in participants with primary IgA nephropathy (IgAN) who are at high risk of progressive kidney disease despite optimized supportive care.

This study is a randomized, double-blind, placebo-controlled Phase II clinical trial to evaluate the efficacy and safety of SHR-2173 in patients with Primary IgA Nephropathy(IgAN). The study consists of a screening period, a run-in period, a 48-week double-blind treatment period, and a 12-week follow-up period. Approximately 84 IgAN patients will be included.

The goal of this clinical trial is to evaluate the safety and tolerability of YKST02 and to explore its potential to treat adults with primary IgA nephropathy (IgAN). The study will also assess how the drug moves through the body and how it affects the immune system. The main questions it aims to answer are: * Is YKST02 safe and well tolerated? * Does YKST02 reduce protein levels in the urine? * How does YKST02 behave in the body (pharmacokinetics, PK)? * How does YKST02 affect the immune system (pharmacodynamics, PD)? Participants are adults with IgAN who have persistent proteinuria despite standard treatment. Participants will: * Receive YKST02 by intravenous (IV) infusion * Be monitored after each dose for safety * Attend clinic visits for safety assessments and laboratory tests * Provide blood and urine samples during the study and follow-up period

This study aims to evaluate the long-term safety of HRS-5965 capsules in patients with primary IgA nephropathy, and also to assess its efficacy in reducing 24-hour urinary protein and delaying the decline in eGFR in these patients.

This multicenter, randomized, double-blind, parallel, placebo-controlled study is being conducted to evaluate the efficacy, and safety of HRS-5965 capsule for primary IgA nephropathy.

The open-label prospective non-randomised controlled aims to assess the efficacy of the combination of immunosupression (IST) and tonsillectomy (TE) in Caucasian patients at high risk of the IgA-nephropathy.

NTQ5082 is a small molecule inhibitor of complement factor B (CFB) that inhibits the enzymatic activity of CFB, thereby blocking the alternative pathway of the complement activation cascade. It is being clinically developed for the treatment of primary IgA nephropathy The main objectives of the study were to assess the efficacy and safety of NTQ5082 capsules in the treatment of patients with primary IgA nephropathy.
