상세 설명
This is a multicenter, randomized, double-blind, placebo-controlled study in approximately 15 patients with primary IgA nephropathy (IgAN).
Participants receiving background therapy will be randomized in a 1:1:1 ratio to receive STL303 capsules dose 1, dose 2, or placebo, administered orally once daily.
The study aims to evaluate the efficacy and safety of STL303 in patients with primary IgAN and to identify the optimal clinical dose.

Inclusion Criteria:
- Male and female patients aged 18 years and older, with primary IgAN confirmed by renal biopsy:
- eGFR (Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI] formula) greater than or equal to 30 mL/min/1.73 m2 at screening and after completion of run-in.
