About this study
Official title: An Open, Single-Arm, Single-Center Clinical Study Assessing the Safety and Efficacy of BCMA-CD19 Targeted Chimeric Antigen Receptor T-Cell Therapy in Multiple Refractory Autoimmune Diseases
The objective of this study is to evaluate the efficacy and safety of BCMA/CD19 chimeric antigen receptor (CAR)-modified T cells in the treatment of autoimmune diseases.
Read the detailed description
The investigators designed a single-center, open-label, single-arm clinical study. Adults with multiple refractory autoimmune diseases will be enrolled, meeting the inclusion criteria. BCMA-CD19 targeted chimeric antigen receptor T-cells will be administered intravenously 1-2 days after preconditioning, at a dose of 3×10^6/kg of CAR-T cells per kilogram (referring to successfully transduced CAR-T cells, not total T cells). The total volume of the CAR-T cell suspension administered per patient will range from approximately 10 to 70 mL, using a "single-dose" regimen. The entire dose of CAR-T cells will be infused intravenously rapidly on day 0. Patients will be evaluated for improvements in clinical and laboratory parameters to assess the safety and efficacy of BCMA-CD19 CAR-T therapy. The primary endpoints include the Complete Remission Rate and laboratory indicators. Secondary endpoints include pharmacokinetic characteristics, long-term efficacy, and safety.

What is being measured
The primary outcome is the main question the study is designed to answer.
Systemic Lupus Erythematosus primary outcome
Percentage of SLE participants who had a response on the SLE Responder Index (SRI-4) at 24 weeks. The Systemic Lupus Erythematosus Responder Index-4 (SRI-4) was used to assess the treatment efficacy in systemic lupus erythematosus (SLE).The scale ranges from 0 to 105, with higher scores indicating worse disease activity. A response is defined as a ≥4-point improvement from baseline at 24 weeks
Measured: From enrollment to the end of treatment at 24 weeks
Sjogren syndrome primary outcome
Proportion of participants with a Sjögren's Tool for Assessing Response (STAR) score of greater than or equal to five at 24 weeks. The STAR is a composite score used to evaluate the clinical response in patients with Sjögren's syndrome. The STAR score ranges from 0 to 9, with higher scores indicating better clinical response. A score of ≥5 at 24 weeks indicates a positive response to treatment.
Measured: From enrollment to the end of treatment at 24 weeks
Inflammatory Myopathy primary outcome
TIS ranges from 0 to 100, with a higher score denoting greater improvement. In adults, TIS can be stratified into the following improvement categories for each patient at each timepoint (minimal improvement [TIS ≥20]; moderate improvement [TIS ≥40]; major improvement [TIS ≥60]). Thus, in the above example the patient would be classified as having moderate improvement [TIS ≥40].
Measured: From enrollment to the end of treatment at 24 weeks
Systemic Sclerosis primary outcome
Change in the Modified Rodnan Skin Score (mRSS) at 24 weeks compared to baseline. The mRSS is a clinical tool used to assess the severity of skin thickening in patients with systemic sclerosis (scleroderma). The mRSS ranges from 0 to 51, with higher scores indicating more severe skin thickening. A decrease in the mRSS score indicates an improvement in skin involvement
Measured: From enrollment to the end of treatment at 24 weeks
Behçet's Disease primary outcome
Proportion of participants with complete remission of oral ulcers at 24 weeks. Oral ulcer resolution is defined as the complete disappearance of all oral ulcers, as observed during clinical examination. A participant is considered to have achieved complete remission if no oral ulcers are present at the 24-week visit
Measured: From enrollment to the end of treatment at 24 weeks
ANCA associated Vasculitis primary outcome
Proportion of participants achieving Birmingham Vasculitis Activity Score (BVAS) of 0 at 24 weeks. BVAS is a composite score used to assess disease activity in vasculitis, ranging from 0 to 63 or higher. Higher scores indicate more severe disease activity. A decrease in BVAS at 24 weeks indicates an improvement in disease activity.
Measured: From enrollment to the end of treatment at 52 weeks
Antiphospholipid Syndrome primary outcome
Number and timing of thrombotic events occurring within 52 weeks.
Measured: From enrollment to the end of treatment at 52 weeks
Acquired Thrombotic Thrombocytopenic Purpura primary outcome
Time to normalization of platelet count.
Measured: From enrollment to the end of treatment at 52 weeks
IgG4-related Disease primary outcome
Proportion of participants with a decrease of greater than or equal to two points in the IgG4-related Disease Responder Index (IgG4RD RI) at 24 weeks compared to baseline. The IgG4RD RI is a composite score used to assess the response to treatment in IgG4-related disease. The score ranges from 0 to 63, with higher scores indicating worse disease activity. A decrease of ≥2 points at 24 weeks indicates a meaningful improvement in disease activity compared to baseline
Measured: From enrollment to the end of treatment at 24 weeks
Secondary outcomes (9)
Systemic Lupus Erythematosus primary secondary Outcome
Change in SLEDAI-2K at 24 weeks compared to baseline. The SLEDAI-2K is a composite index used to assess disease activity in systemic lupus erythematosus. The score ranges from 0 to 105, with higher scores indicating more severe disease activity. An improvement of ≥4 points in the SLEDAI-2K score at 24 weeks compared to baseline is considered a clinically meaningful response, reflecting a reduction in disease activity
Measured: From enrollment to the end of treatment at 24 weeks
Sjogren syndrome secondary outcome
Change in the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) score at 24 weeks compared to baseline. The ESSDAI is a composite score used to assess disease activity in patients with Sjögren's syndrome. The score ranges from 0 to 123, with higher scores indicating more severe disease activity. A decrease in the ESSDAI score at 24 weeks compared to baseline indicates an improvement in disease activity.
Measured: From enrollment to the end of treatment at 24 weeks
Inflammatory Myopathy secondary outcome
Change in the Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI) score at 24 weeks compared to baseline. The CDASI is a composite score used to assess the severity and extent of skin involvement in patients with cutaneous dermatomyositis. The score ranges from 0 to 132, with higher scores indicating more severe disease activity. A decrease in the CDASI score at 24 weeks compared to baseline indicates an improvement in skin involvement and disease severity.
Measured: From enrollment to the end of treatment at 24 weeks
Systemic Sclerosis secondary outcome
Change in the Health Assessment Questionnaire Disability Index (HAQDI) score at 24 weeks compared to baseline. The HAQDI is a widely used measure of disability in patients with chronic diseases, assessing the impact of disease on daily functioning. The score ranges from 0 to 3, with higher scores indicating greater disability and more severe functional impairment. A decrease in the HAQDI score at 24 weeks compared to baseline indicates an improvement in the patient's functional status and a reduction in disability.
Measured: From enrollment to the end of treatment at 24 weeks
Behçet's Disease secondary outcome
Change in the Behçet's Syndrome Activity Score (BSAS) at 24 weeks compared to baseline. The BSAS is a composite score used to assess the disease activity in patients with Behçet's syndrome, considering both clinical signs and symptoms. The score ranges from 0 to 85, with higher scores indicating greater disease activity and more severe symptoms. A decrease in the BSAS at 24 weeks compared to baseline indicates a reduction in disease activity and an improvement in clinical symptoms.
Measured: From enrollment to the end of treatment at 24 weeks
ANCA associated Vasculitis secondary outcome
Change in the Birmingham Vasculitis Activity Score (BVAS) at 52 weeks compared to baseline. The BVAS is a composite score used to assess the disease activity in patients with vasculitis. The score ranges from 0 to 63, with higher scores indicating greater disease activity. A decrease in the BVAS at 52 weeks compared to baseline indicates a reduction in disease activity and an improvement in clinical symptoms.
Measured: From enrollment to the end of treatment at 52 weeks
Antiphospholipid Syndrome secondary outcome
Number and timing of bleeding events occurring within 52 weeks.
Measured: From enrollment to the end of treatment at 52 weeks
Acquired Thrombotic Thrombocytopenic Purpura secondary outcome
Time to relapse of thrombotic thrombocytopenic purpura (TTP) within 52 weeks.
Measured: From enrollment to the end of treatment at 52 weeks
IgG4-related Disease secondary outcome
IgG4-related Disease Responder Index (IgG4RD RI) scores at each follow-up visit. The IgG4RD RI is a composite index used to assess the response to treatment in patients with IgG4-related disease (IgG4-RD). The score is based on the evaluation of clinical symptoms, laboratory markers, and imaging results. The IgG4RD RI score ranges from 0 to 63, with higher scores indicating greater disease activity and worse outcomes. A decrease in the IgG4RD RI score at follow-up visits compared to baseline suggests improvement in disease activity and response to treatment.
Measured: From enrollment to the end of treatment at 24 weeks

The mRSS is a clinical tool used to assess the severity of skin thickening in patients with systemic sclerosis (scleroderma). The mRSS ranges from 0 to 51, with higher scores indicating more severe skin thickening. A decrease in the mRSS score indicates an improvement in skin involvement
Behçet's Disease primary outcome
Time frame: From enrollment to the end of treatment at 24 weeks
Proportion of participants with complete remission of oral ulcers at 24 weeks. Oral ulcer resolution is defined as the complete disappearance of all oral ulcers, as observed during clinical examination. A participant is considered to have achieved complete remission if no oral ulcers are present at the 24-week visit
ANCA associated Vasculitis primary outcome
Time frame: From enrollment to the end of treatment at 52 weeks
Proportion of participants achieving Birmingham Vasculitis Activity Score (BVAS) of 0 at 24 weeks. BVAS is a composite score used to assess disease activity in vasculitis, ranging from 0 to 63 or higher. Higher scores indicate more severe disease activity. A decrease in BVAS at 24 weeks indicates an improvement in disease activity.
Antiphospholipid Syndrome primary outcome
Time frame: From enrollment to the end of treatment at 52 weeks
Number and timing of thrombotic events occurring within 52 weeks.
Acquired Thrombotic Thrombocytopenic Purpura primary outcome
Time frame: From enrollment to the end of treatment at 52 weeks
