Overview
This study is a multicenter, randomized phase II clinical study to evaluate Efficacy and safety, while observing pharmacokinetic profiles, pharmacodynamic effects, and immunogenicity of CM338 in subjects with Immunoglobulin A(IgA) nephropathy.
Description
In 1968, immunoglobulin A nephropathy (IgAN) was developed by French pathologist Dr. Jean Berger and his colleague Dr. Nicole Hinglais that what is described as glomerular "immunoglobulin A (IgA)-immune globule" - immune globule Protein G (IgG) intercapillary deposition" of kidney disease, the main pathological feature of which is on the glomerulus IgA deposition, usually accompanied by local cell proliferation and stromal dilation. Since there is not enough specificity and spirit Biomarkers of sensitivity, the only way to confirm the diagnosis is renal biopsy.
