Phase III Study of Telitacicept in Patients With IgA Nephropathy
Study Details
Study Description
Brief Summary
The goal of this clinical trial is to compare Telitacicept with placebo in patients with IgA nephropathy.
The main questions it aims to answer are:
-
To evaluate the clinical efficacy of Telitacicept in patients with IgA nephropathy.
-
To evaluate the safety and adverse reaction of Telitacicept in patients with IgA nephropathy.
Participants will be subcutaneously injected with 240mg of Telitacicept once per week. Researchers will compare placebo-controlled group to see if Telitacicept works better.

Outcome Measures
Primary Outcome Measures
- Complete clinical response [3-year]
a. Proteinuria: protein-to-creatinine ratio <0.2; b. Stable renal function: eGFR decreased by less than 5ml/min/1.73m2 from baseline at the end of the 3-year trial phase.
- The absolute value of eGFR [3-year]
The absolute value of eGFR decreased by more than 15 ml/min/1.73m2 over 3 years from baseline
- Changes in 24-hour urinary protein [104 weeks]
Changes in 24-hour urinary protein at week 104 compared with baseline.
Secondary Outcome Measures
- eGFR decrease [3-year]
The estimated glomerular filtration rate (eGFR) decreased by more than 30 ml/min/1.73 m2 from baseline.
- Need for dialysis [3-year]
progression to end-stage renal disease
