Universal STAR-T Cell Injection in Generalized Myasthenia Gravis

Summary

This is a Phase I, single-arm, open-label, dose-escalation and dose-expansion study. This is an exploratory clinical study of universal STAR-T cell injection in patients with refractory generalized myasthenia gravis (GMG). Approximately 10-24 participants aged 18-65 years (inclusive) with the condition are planned to be enrolled. The primary objective is to evaluate the safety, tolerability, preliminary efficacy, pharmacokinetic/pharmacodynamic (PK/PD) profile, and immunogenicity of universal STAR-T cell injection. The starting dose is 1.5E6 STAR+ T cells/kg, administered as a single intravenous infusion.Based on safety, PK results, and preliminary efficacy data obtained from the initial dose cohorts, a recommended dose will be selected for subsequent dose-expansion studies to further systematically evaluate the safety and efficacy of universal STAR-T cell injection. This study includes the screening period (from D-28 to D-6), the pre-clearance treatment and rest observation period (from D-5 to D-1), the cell infusion and main study endpoint observation period (from D0 to W12 after infusion), and the follow-up period (from W12 after infusion to W104). The study is being conducted at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology.
