Brief Summary:
The goal of this Phase I clinical trial is to evaluate the safety and tolerability of autologous CD19-targeted chimeric antigen receptor T-cell (CAR-T) therapy in adults with refractory systemic lupus erythematosus who have demonstrated inadequate response to standard-of-care immunosuppressive treatments.
The primary questions this study aims to address are:
What is the incidence, nature, and severity of treatment-emergent adverse events following CD19 CAR-T cell infusion? Is administration of CD19 CAR-T cell therapy feasible and tolerable in patients with refractory systemic lupus erythematosus? This study is conducted as a single-arm trial without a comparison group.
Participants will:
Undergo leukapheresis for collection of autologous peripheral blood mononuclear cells Receive a protocol-defined lymphodepleting chemotherapy regimen prior to CAR-T cell infusion Receive a single intravenous infusion of approximately 1.0 × 10⁶ CD19 CAR-T cells per kilogram of body weight Undergo scheduled clinical evaluations, laboratory testing, and longitudinal follow-up to assess safety, tolerability, and clinical parameters
Detailed Description:
This is a Phase I, single-center, open-label clinical trial evaluating the safety of autologous CD19-targeted chimeric antigen receptor T-cell (CAR-T) therapy in patients with refractory systemic lupus erythematosus (SLE).
Systemic lupus erythematosus is a chronic autoimmune disease characterized by immune dysregulation and pathogenic autoantibody production, with B lymphocytes playing a central role in disease pathophysiology. Targeting CD19-expressing B cells represents a potential therapeutic strategy for patients with disease refractory to standard immunosuppressive therapies.
Autologous CD19 CAR-T cells will be generated from peripheral blood T cells collected by leukapheresis. Cells will be genetically modified ex vivo to express a CD19-specific chimeric antigen receptor, expanded, and released for clinical administration following protocol-defined quality control testing and regulatory requirements.
Participants will receive a lymphodepleting chemotherapy regimen prior to a single intravenous infusion of CD19 CAR-T cells. Treatment administration and post-infusion monitoring will be conducted according to the protocol-specified safety and observation plan.
Following infusion, participants will be monitored for treatment-emergent adverse events, including CAR-T-associated toxicities such as cytokine release syndrome, immune effector cell-associated neurotoxicity, cytopenias, and infections. Safety evaluations will include serial clinical assessments and laboratory monitoring.
Exploratory assessments will evaluate immunological parameters, including B-cell depletion and reconstitution, autoantibody profiles, and selected biomarkers of disease activity. Participants will undergo longitudinal follow-up to assess early and delayed adverse events and the persistence of immunological effects, in accordance with regulatory guidance for gene-modified cell therapies.
