Summary

This single-center, prospective, single-arm study will evaluate the efficacy and safety of telitacicept in 10 adults with biopsy-proven proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID).

Eligible participants (≥18 y, ≥1 g/day proteinuria, eGFR ≥20 mL/min/1.73 m²) will receive 160 mg telitacicept subcutaneously once weekly for 24 weeks after a 12-week run-in on maximally tolerated ACEi/ARB.

The primary endpoint is change in 24-hour urine protein from baseline to Week 24. Secondary endpoints include changes in eGFR, urine red-blood-cell count, and serum immunoglobulin/complement levels. Safety will be monitored throughout.

Recruitment is planned from May 2025 to May 2027 at Peking University First Hospital.

Conditions

  • Proliferative Glomerulonephritis With Monoclonal Immunoglobulin Deposits

Interventions

DRUG

Telitacicept 160mg

Telitacicept (RC18) is a recombinant TACI-Fc fusion protein that simultaneously neutralizes B-lymphocyte stimulator (BLyS) and a proliferation-inducing ligand (APRIL), thereby inhibiting B-cell differentiation and plasma-cell survival. In this study, it is supplied as a sterile, preservative-free, lyophilized powder (160 mg/vial) that is reconstituted with 1 mL water for injection and administered subcutaneously into the abdomen or thigh at a fixed dose of 160 mg once weekly for 24 weeks. Each injection is performed by trained study personnel, and pre-filled backup syringes are available to ensure exact dosing. No dose escalation or tapering is planned; dose reductions or temporary discontinuation are allowed only for predefined safety criteria.
