Brief Summary
The investigators developed a dual-target CAR-T targeting CD38 and CS1. Previous experimental results showed that the investigators double-target CAR-T not only had a good killing effect on CD38/CS1 d...

Exclusion
- Patients with expected survival of less than 3 months. 2. Patients whose disease progression was so rapid that a complete treatment cycle could not be ensured according to the investigator at the time of enrollment. 3. Patients with primary tumors other than melanoma skin cancer (e.g. cervical cancer, bladder cancer, breast cancer) (unless cured for more than 3 years). 4. Patients with infections including fungal, bacterial, viral or other uncontrolled infections or those requiring level 4 isolation. 5. Patients who test positive for HIV, HBV and HCV. 6. Patients with central nervous system diseases including stroke, epilepsy, dementia or autoimmune central nervous system diseases. 7. Patients with myocardial infection, cardiac angiography or stent, active angina pectoris or other significant clinical symptoms, or with cardiogenic asthma or cardiovascular plasma cell infiltration in the 12 months prior to enrollment. 8. People who are receiving anticoagulant therapy or have severe coagulation disorders. 9. According to the judgment of the researcher, the drug treatment that the patient is receiving will affect the safety and effectiveness study of this project. 10. Patients with allergy or history of allergy to the biologics used in this project. 11. Pregnant or lactating women. 12. Systematic use of systemic or systemic steroid drugs within 2 weeks prior to treatment (except those who have recently or currently used inhaled steroids). 13. The efficiency of T cell transduction by replication-deficient lentivirus is less than 30%, or the amplification ability is insufficient (times) in response to CD3 / CD28 co-stimulatory signals. 14. Patients with other uncontrolled diseases deemed unsuitable by the researchers. 15. Any situation that the investigator believes may increase the risk to the subject or interfere with the test results. 16. Patients who are also participating in other clinical studies.
