Brief summary: This is a single arm study to evaluate the efficacy and safety of BCMA-targeted CAR-T cells therapy for patients with relapsed/refractory Multiple Myeloma.

Detailed description: There are limited options for treatment of relapse/refractory Multiple Myeloma. BCMA is expressed on most Multiple Myeloma cells so it is an ideal target for CAR-T. In this study, investigators will evaluate the safety and efficacy of CAR-T targeting BCMA in patients with relapsed/refractory Multiple Myeloma. The primary goal is safety and efficiency assessment, including adverse events and disease status after treatment.

Eligibility criteria: Inclusion Criteria:

1. Signed written informed consent;
2. Diagnose as relapsed /refractory multiple myeloma or other plasma cell disease, and meet one of the following conditions:

   1. Failed to standard chemotherapy regimens;
   2. Relapse after complete remission, high-risk and / or refractory patients ;
   3. Relapse after hematopoietic stem cell transplantation;
3. Evidence for cell membrane BCMA expression；
4. All genders, ages: 18 to 75 years；
5. The expect time of survive is above 3 months;
6. KPS\>60；
7. No serious mental disorders ;
8. Left ventricular ejection fraction ≥50%
9. Sufficient hepatic function defined by ALT/AST≤3 x ULN and bilirubin≤2 x ULN;
10. Sufficient renal function defined by creatinine clearance≤2 x ULN;
11. Sufficient pulmonary function defined by indoor oxygen saturation≥92%;
12. With single or venous blood collection standards, and no other cell collection contraindications;
13. Ability and willingness to adhere to the study visit schedule and all protocol requirements.

Exclusion Criteria:

1. Previous history of other malignancy;
2. Presence of uncontrolled active infection;
3. Evidence of disorder that need the treatment by glucocorticoids;
4. Active or chronic GVHD；
5. The patients treatment by inhibitor of T cell；
6. Pregnant or breasting-feeding women;
7. Any situation that investigators regard not suitable for attending in this study (e.g. HIV , HCVinfection or intravenous drug addiction) or may affect the data analysis.
