Study Endpoints
Primary Endpoints
Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]
28 dyas

The incidence of adverse events after CAR-T cell infusion was assessed by CTCAE, version 5.0.

Total improvement score (TIS) after anti-CD19 UCAR-T cells infusion.
6 months

The total improvement score between 0-100 also corresponds to the degree of improvement, with higher improvement scores indicating greater improvement.

Disease Activity Score (DAS) after anti-CD19 UCAR-T cells infusion.
6 months

Including musculoskeletal system score and skin mucosal score, with a total score of 20 points. The higher the score, the higher the disease activity

Changes of myositis specific antibody levels and serum muscle enzyme levels after anti-CD19 UCAR-T cells infusion.
6 months
Improvement in muscle inflammation infiltration by MRI after anti-CD19 UCAR-T cells infusion.
6 months
Childhood Myositis Assessment Scale (CMAS) score after anti-CD19 UCAR-T cells
6 months

The total score is 52 points, the lower the score, the weaker the muscle strength and the more severe the disease.
