Refractory Systemic Lupus Erythematosus

This is an investigator-initiated, open-label, single-arm study to determine safety and preliminary efficacy of NK010 or NK042 in combination with rituximab (RTX) for the treatment of patients with refractory systemic lupus erythematosus (SLE) or lupus nephritis (LN) in China.

This is a single-center, open-label, exploratory clinical study designed to evaluate the efficacy and safety of IASO207 Injection (in vivo CAR-T) in patients with active refractory systemic lupus erythematosus.

study evaluates a biomarker-guided strategy to assign adults with refractory SLE to autologous CAR-T therapy targeting either CD19 or BCMA. Participants undergo centralized screening immunophenotyping to determine whether their disease appears B-cell-dominant (CD19-preferred) or plasma-cell-dominant (BCMA-preferred), followed by leukapheresis, lymphodepletion, and a single CAR-T infusion. The main goals are to assess safety, determine a recommended Phase 2 dose within each arm, and estimate remission rates by Week 24.

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

The study is a single-arm, open-label clinical trial intended to recruit 6 refractory SLE subjects who meet the inclusion and exclusion criteria. The subjects will receive IM19 CAR-T cell infusion therapy at a dose of 1×10\^6/kg or 1×10\^8 CAR-T cells . The primary endpoint is to evaluate the improvement in SLE disease activity (SLEDAI-2K) at 90 days and the occurrence of adverse events related to IM19 CAR-T cell infusion within 28 days post-infusion. Additionally, the long-term efficacy was evaluated, including the improvement of SLEDAI-2K score and achieving lupus low disease activity (LLDAS) at day 180 and day 360, and renal response at day 180 and day 360. The persistence and duration of IM19 CAR-T cells in the peripheral blood of subjects will also be evaluated. The study plan includes five phases: screening phase, cell collection phase, lymphodepletion pretreatment phase, cell infusion phase, and follow-up phase.

This is an investigator-initiated, open-label, single-arm study to determine safety and preliminary efficacy of NK510 for the treatment of patients with refractory systemic lupus erythematosus (SLE) in China.
