About this trial
A study to investigate the impact of iptacopan treatment on the underlying immunopathology in patients with IgAN by assessing changes in key clinical and molecular markers from baseline to 9 months. The study aims to provide insights into the treatment's systemic and kidney-specific aspects by quantifying the change in mesangial C3c containing fragments deposition, as an indicator of complement activation, and evaluating a variety of biomarkers related to kidney function, damage, and disease progression, including but not limited to Oxford MEST-C score.
Eligibility criteria
Qualifiers
Signed informed consent must be obtained prior to participation in the study; participants should be able to communicate well with the investigator, understand and comply with the requirements of the study.
Male and female participants ≥18 years of age with biopsy-confirmed IgA nephropathy and an eGFR ≥ 30 mL/min/1.73m2. eGFR will be calculated using the CKD-EPI 2009 formula.
Proteinuria as assessed at screening by UPCR ≥ 0.8g/g or 1g/d sampled from FMV.
Biopsy at baseline should confirm IgAN with < 50% tubulointerstitial fibrosis.
Disqualifiers
Any secondary IgAN (at historic or baseline biopsies) as defined by the investigator and IgA vasculitis Henoch-Scholein Purpura (HSP). Secondary IgAN can be associated with cirrhosis, celiac disease, Human Immunodeficiency Virus (HIV) infection, dermatitis herpetiformis, seronegative arthritis, small-cell carcinoma, lymphoma, disseminated tuberculosis, bronchiolitis obliterans, and inflammatory bowel disease, familial Mediterranean fever, etc.
Any secondary diagnosis at baseline biopsy (other than IgA nephropathy).
Evidence of significant urinary obstruction or difficulty in voiding; any urinary tract disorder other than IgAN at screening and before first study drug administration.
Current or planned usage of any homeopathic and/or herbal medications for IgAN disease progression, such as but not limited to Lei Gong Teng.
