Brief summary: Clinical trial for the safety and efficacy of CS1-targeted CAR-T Cells therapy for relapsed multiple myeloma after BCMA CAR-T cells therapy

Detailed description: This is a single arm, open-label, single-center study. This study is indicated for relapsed CS1+ multiple myeloma, the selections of dose levels and the number of subjects are based on clinical trials of similar foreign products. 50 patients will be enrolled for this trial. Primary objective is to explore the safety, main consideration is dose-related safety.

Eligibility criteria: Inclusion Criteria:

1. Histologically confirmed diagnosis of CS1+ multiple myeloma (MM)：

   1. Patients with MM relapsed after BCMA CAR-T therapy;Or MM with positive CS1 expression and negative BCMA expression;
   2. Relapsed after hematopoietic stem cell transplantation;
   3. Cases with recurrent positive minimal residual disease;
   4. Extramedullary leision which is hard to be eradicated by chemotherapy or radiotherapy.
2. Anticipated survival time more than 12 weeks;
3. Male or female aged 30-75 years;
4. Those who voluntarily participated in this trial and provided informed consent.

Exclusion Criteria:

Subjects with any of the following exclusion criteria were not eligible for this trial:

1. History of craniocerebral trauma, conscious disturbance, epilepsy, cerebrovascular ischemia, and cerebrovascular hemorrhagicdiseases;
2. Electrocardiogram shows prolonged QT interval, severe heart diseases such as severe arrhythmia in the past;
3. Pregnant (or lactating) women;
4. Patients with severe active infections (excluding simple urinary tract infectionand bacterial pharyngitis);
5. Active infection of hepatitis B virus or hepatitis C virus;
6. Concurrent therapy with systemic steroids within 2 weeks prior to screening, except for the patients recently or currently receiving inhaled steroids;
7. Previously treated with any CAR-T cell product or other genetically-modified T cell therapies;
8. Creatinine\>2.5mg/dl, or ALT / AST \> 3 times of normal amounts, or bilirubin\>2.0 mg/dl;
9. Other uncontrolled diseases that were not suitable for this trial;
10. Patients with HIV infection;
11. Any situations that the investigator believes may increase the risk of patients or interfere with the results of study.
