A Clinical Study Evaluating the Safety and Efficacy of GT719 Universal Cell Injection in the Treatment of Immune-mediated Kidney Diseases

This study is a single-arm, open-label, dose-escalation and dose-expansion clinical trial, divided into two phases: the first phase is the dose-escalation phase, and the second phase is the dose-expansion phase. In the dose-escalation phase, approximately 9-18 adult participants with immune-mediated kidney diseases are planned to be enrolled and treated with GT719 universal cell injection. The objectives of this phase are to evaluate the safety and tolerability of the product, determine the recommended dose (RD) for subsequent studies, conduct a preliminary assessment of its clinical efficacy, and investigate the pharmacokinetic and pharmacodynamic characteristics. Upon completion of the dose-escalation phase, after evaluation by investigators and collaborators, an appropriate dose will be selected for the dose-expansion phase. An additional 12 participants will be enrolled to fully assess the safety and efficacy of the product.

Telitacicept for PGNMID: A Single-Arm Study

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.
