Safety and Efficacy of STL303 In Patients With Primary Immunoglobulin A (IgA) Nephropathy
A Multicenter, Randomised, Double-Blinded, Placebo-Controlled Study to Evaluate the Safety and Efficacy of STL303 In Patients With Primary Immunoglobulin A (IgA) Nephropathy
Przegląd badań
Szczegółowy opis
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:

Exclusion Criteria:
- Secondary IgAN or unclear exclusion of secondary causes.
- Rapidly progressive IgAN (eGFR decline greater than or equal to 50% in 3 months, or less than 50% but at high risk).
