Brief summary: The goal of this clinical trial is to study the feasibility and efficacy of anti-B-Cell Maturation Antigen (BCMA) expressing T cells in treating patients with multiple myeloma.

Detailed description: Participants with BCMA-positive relapsed/refractory multiple myeloma can participate if all eligibility criteria are met. Tests required to determine eligibility include disease assessments, a physical exam, Electrocardiograph, CT/MRI/PET, and blood draws. Participants receive chemotherapy prior to the infusion of BCMA CAR+ T cells. After the infusion, participants will be followed for side effects and effect of BCMA CAR+ T cells. Study procedures may be performed while hospitalized.

Eligibility criteria: Inclusion Criteria:

* Expected survival \> 12 weeks
* Diagnosis of Multiple Myeloma by MWG criteria 20
* Patients previously received at least 3 different prior treatment regimens for multiple myeloma, including alkylating agent, protein inhibitors, and immunomodulator, and have disease progression in the past 60 days
* Important organs function enough to tolerate this therapy
* At least 90 days after stem cell transplantation
* Accessible to intravenous injection, and no white blood cell collection contraindications
* Sexually active patients must be willing to utilize one of the more effective birth control methods for 30 days after the CTL infusion. Male partner should use a condom
* Able to understand and sign the Informed Consent Document.

Exclusion Criteria:

* Patients with symptoms of central nervous system
* Patients with second malignancies in addition to multiple myeloma
* Active hepatitis B or C, HIV infections
* Any other active diseases could affect the enrollment of this trial
* Suffering severe cardiovascular or respiratory disease
* Poorly controlled hypertension
* Long term use of immunosuppressive agents after organ transplantation, except currently receiving or recently received glucocorticoid treatment
* A history of mental illness and poorly controlled
* Screening showing target cell transduction efficacy is lower than 30%, or T cell proliferation is not enough for infusion (less than 5 fold)
* Occurrence of unstable pulmonary embolism, deep vein thrombosis, or other major arterial/venous thromboembolic events 30 days prior to assignment
* Women of child-bearing potential who are pregnant or breastfeeding during therapy, or have a planned pregnancy with 2 months after therapy
* Women of child-bearing potential who are not willing to practice birth control from the time of enrollment on this study and for 2 months after receiving the preparative regimen. Women of child bearing potential must have a negative serum or urine pregnancy test performed within 48 hours before infusion
* Active systemic infections or uncontrolled infection within 14 days prior enrollment
* Subjects suffering disease affects the understanding of informed consent or complying with study protocol.
