Sequential CAR-T Cells Targeting BCMA/GPRC5D in Patients With Relapsed/ Refractory Multiple Myeloma
This is an open, single-arm, clinical study to evaluate the efficacy and safety of chimeric antigen receptor T cell immunotherapy (CAR-T) targeting BCMA or GPRC5D or both sequentially in the treatment of Relapsed/ Refractory Multiple myeloma
• Expected survival time ≥3 months;
• Subjects with recurrent/refractory Multiple Myeloma who have failed standard treatment or lack effective treatment, Including but not limited to systemic lupus erythematosus, idiopathic inflammatory myopathy, systemic sclerosis, IGG4-associated diseases, primary Sjogren's syndrome, rheumatoid arthritis, connective tissue disease-associated interstitial lung disease, immune thrombocytopenia, primary biliary cholangitis, etc.
• Histological evidence of non-suppurative destructive cholangitis and small bile duct destruction.
• Liver and kidney function, cardiopulmonary function meet the following requirements:
• Creatinine ≤1.5×ULN; (2) Electrocardiogram showed no clinically significant abnormal bands;
• Blood oxygen saturation \>91% in non-oxygen state;
• Total bilirubin ≤2×ULN; ALT and AST≤2.5 x ULN; ALT and AST abnormalities due to disease, such as liver infiltration or bile duct obstruction, were determined to be less than 5×ULN. If Gilbert syndrome is diagnosed, the total bilirubin index can be relaxed to ≤3.0×ULN and the direct bilirubin ≤1.5×ULN.
• No serious mental disorders;
• Can understand this test and has signed the informed consent.
