Phase 3
Recruiting
Conditions
Primary IgA Nephropathy
Interventions
Registration Number
NCT05799287
Lead Sponsor
RemeGen Co., Ltd.
Brief Summary

The purpose of this study is to evaluate the efficacy and safety of Telitacicept in patients with primary IgA nephropathy.

Detailed Description

This study consists of a 5-week screening period, a double-blind treatment period divided into phase A and phase B. Eligible subjects will be randomly assigned in a 1:1 ratio to receive either Telitacicept 240mg or placebo. Subjects will be given SC Telitacicept or placebo once a week for a total of 39 doses in phase A and once every 2 weeks for a total of 32 doses in phase B.

Primary endpoint of phase A will be measured at week 39. Primary endpoint of phase B will be measured at week 104.

Primary Outcome Measures
NameTimeMethod
Change from baseline in urine protein creatinine ratio (UPCR)39 weeks

Based on a 24-hour urine collections.

Annualized estimated glomerular filtration rate (eGFR) slope104 weeks

eGFR is calculated using the CKD-EPI formula.

Secondary Outcome Measures
NameTimeMethod
Proportion of patients with a 30% decrease in estimated glomerular filtration rate (eGFR) compared with baseline39 weeks

eGFR is calculated using the CKD-EPI formula.

Time to 30% reduction from baseline in eGFRup to 104 weeks

eGFR is calculated using the CKD-EPI formula and confirmed by a second sample collection and calculation after at least 4 weeks.

Proportion of patients with a 40% decrease in estimated glomerular filtration rate (eGFR) compared with baselineup to 104 weeks

eGFR is calculated using the CKD-EPI formula and confirmed by a second sample collection and calculation after at least 4 weeks.

Proportion of patients received rescue treatment.up to 104 weeks

patients using systemic immunosuppressive medications, glucocorticoids (GCSs), etc.

Incidence and severity of adverse eventsup to 104 weeks
