Diagnosis of multiple myeloma (MM) with reference to the diagnostic criteria of the Guidelines for the Diagnosis and Treatment of Multiple Myeloma in China (Revised in 2022); 2. Those who have received at least one line of systemic anti-myeloma therapy in the past (including lenalidomide and proteasome inhibitors, see Appendix 4 for the count of myeloma treatment lines), and meet the definition of relapsed or refractory; Definition of recurrence: disease progression that occurs at least 60 days after the last treatment (except for those who have relapsed more than 1 year after treatment) with an evaluation of the efficacy of previous treatment regimens of MR or better; Refractory definition: progression during prior treatment or progression within 60 days after the last treatment; or have not reached MR or above after at least 2 courses of treatment; or treatment intolerance. 3. Age 18-75 years old, male or female, if the subject is of childbearing age, should use effective contraceptive measures, must agree to comply with all contraceptive requirements: 1) Women of childbearing potential must agree to and comply with the contraceptive measures specified in the protocol: starting from 4 weeks before the use of this product, during the treatment period, during the dose suspension period and within 4 weeks after the termination of treatment, two reliable contraceptive methods (one highly effective contraceptive method - tubal ligation, intrauterine device, hormones (contraceptive pills, needles, patches, vaginal rings or implants) or partner vasectomy, and another effective contraceptive method - rubber or synthetic condoms, diaphragms or cervical caps for men. Effective contraception is required even if there is a history of infertility unless due to hysterectomy; 2) Men of childbearing potential must continue to use rubber or synthetic condoms during sexual contact with women of childbearing potential during treatment, during dose suspension and within 4 weeks after treatment termination from 4 weeks before treatment with this product, even if they have successfully undergone vasectomy; 4.

Hematology meets the following conditions: 1) ANC>=1×10^9/L (granulocyte colony-stimulating factor was not used within 7 days), when the plasma cells in the bone marrow were = 50%, the neutrophil count was not specifically required; 2) PLT>=75×10^9/L (no platelet transfusion or thrombopoietin within 7 days), when plasma cells in the bone marrow 1. Refer to the diagnostic criteria of the "Guidelines for the Diagnosis and Treatment of Multiple Myeloma in China (Revised in 2022)" to diagnose multiple myeloma (MM); 2.
