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
Přehled studie
Detailní popis
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.

Popis
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.
- UPCR greater than or equal to 0.75 g/g at screening and after completion of run-in.
- Vaccinated against Neisseria meningitidis and Streptococcus pneumoniae before the first dose.
- Have received stable treatment with RASis (ACEi or ARB) at the maximum recommended dose or MTD for at least 90 days prior to the first dose.

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).
