Multiple myeloma is a blood cancer that is usually incurable. T cells are part of the immune system. Researchers think changing a person s T cells to recognize their cancer could help the person s body kill tumor cells. This is a new approach that uses a patient s own cells to target multiple myeloma.
Objective:
To see if giving anti-SLAM7 CAR T cells with a stop switch to people with multiple myeloma is safe andto see if adding a gene to stop T-cell activity can limit toxicity of this therapy.
Eligibility:
People ages 18-73 with multiple myeloma for which prior standard treatment has not worked
Design:
Participants will be screened with:
-Medical history
-Physical exam
-Blood, urine, and heart tests
-Bone marrow samples: A needle inserted into the participant s bone will remove marrow.
-Imaging scans: Participants will lie in a machine that takes pictures of the body.
Participants will have apheresis. They will receive a catheter or central line: A plastic tube will be inserted into a chest or arm vein. Blood will be removed and the T cells separated. The rest of the blood will be returned to the participant. The T cells will be manipulated in the lab.
Participants will get chemotherapy through the central line for 3 days.
Participants will receive the manipulated T cells through the central line. They will stay in the hospital at least 9 days.
Participants will have follow-up visits 2 weeks then 1, 2, 3, 4, 6, 9, and 12 months after the infusion. They will then have visits every 6 months for 3 years. Then they will be contacted once per year for 15 years. All visits will include blood tests, and 3 visits will include bone marrow biopsies.

INCLUSION CRITERIA - MULTIPLE MYELOMA: - SLAMF7 expression must be detected on malignant plasma cells from either bone marrow or a plasmacytoma by flow cytometry or immunohistochemistry. A specific quantitative level of SLAMF7 expression for eligibility is not specified, but patients with multiple myeloma cells that are negative for SLAMF7 by flow cytometry and immunohistochemistry will not be enrolled. These assays must be performed at the National Institutes of Health (NIH). It is not required that the specimen used for SLAMF7 determination comes from a sample that was obtained after the patient s most recent treatment. If paraffin embedded unstained samples of bone marrow involved with MM or a plasmacytoma are available, these can be shipped to the NIH for SLAMF7 staining, otherwise new biopsies will need to be performed for determination of SLAMF7 expression. - SLAMF7 expression will need to be documented on the majority of malignant plasma cells by flow cytometry at the NIH at some time after the original CAR-SLAMF7 T-cell infusion in all patients undergoing a second CAR-SLAMF7 T-cell infusion on this clinical trial. - Bone marrow plasma cells must make up less than or equal to 50% of total bone marrow cells based on a bone marrow biopsy performed within 24 days of the start of protocol treatment. - Patients must have received at least 3 different prior treatment regimens for multiple myeloma - Must have prior exposure to an immunomodulatory drug (IMiD) such as lenalidomide and a proteasome inhibitor - Patients must have measurable MM as defined by at least one of the criteria below. -- Serum M-protein greater or equal to 0.6 g/dL. -- Urine M-protein greater or equal to 200 mg/24 h. -- Serum free light chain (FLC) assay: involved FLC level greater or equal to 10 mg/dL (100 mg/L) provided serum FLC ratio is abnormal. -- A biopsy-proven plasmacytoma at least 1.5 cm in largest dimension -- Bone marrow core biopsy with 30% or more plasma cells INCLUSION CRITERIA - OTHER: - Greater than or equal to 18 years of age and less than or equal to age 73. - Able to understand and sign the Informed Consent Document. - Clinical performance status of ECOG 0-2 - Patients of both sexes must be willing to practice birth control from the time of enrollment on this study and for four months after last day of receiving protocol treatment. - Seronegative for HIV antibody. (The experimental treatment being evaluated in this protocol depends on an intact immune system. Patients who are HIV seropositive can have decreased immune-competence and thus are less responsive to the experimental treatment and more susceptible to its toxicities.) - A patient with a negative blood PCR test for hepatitis B DNA test can be enrolled. If hepatitis B DNA (PCR) testing is not available, patients with a negative hepatitis B surface antigen and negative hepatitis B core antibody can be enrolled. - Patients must be tested for the presence of Hepatitis C antigen by PCR and be HCV RNA negative in order to be eligible. Only if Hepatitis C PCR testing is not available in a timely manner, patients who are Hepatitis C antibody-negative can be enrolled. - Absolute neutrophil count greater than or equal to 1000/mm^3 without the support of filgrastim or other growth factors within the previous 10 days. - Platelet count greater than or equal to 55,000/mm^3 without transfusion support in the past 14 days. - Hemoglobin greater than or equal to 8.0 g/dL. - Less than 5% plasma cells in the peripheral blood leukocytes - Serum ALT and AST less or equal to 2.5 times the upper limit of the institutional normal. - Serum creatinine less than or equal to 1.5 mg/dL. - Total bilirubin less than or equal to 2.0 mg/dL, except in patients with Gilbert's Syndrome who must have a total bilirubin less than 3.0 mg/dL. - At least 14 days must have elapsed since any prior systemic therapy at the time the patient starts the cyclophosphamide and fludarabine conditioning regimen, and patients toxicities must have recovered to a grade 1 or less (except for toxicities such as alopecia or vitiligo or cytopenias). - Because this protocol requires collection of autologous blood cells by leukapheresis in order to prepare CAR-SLAMF7 T cells, systemic anti-myeloma therapy including systemic corticosteroid steroid therapy of greater than 5 mg/day of prednisone or equivalent dose of another corticosteroid are not allowed within 14 days prior to the required leukapheresis. - Normal cardiac ejection fraction (greater than or equal to 50% by echocardiography) and no evidence of hemodynamically significant pericardial effusion as determined by an echocardiogram. - For patients with past participation in gene-therapy, cryopreserved PBMC that have not been genetically-engineered must be available. -Patients receiving prior gene therapy outside of NIH will not be eligible. Patients who previously received CAR T-cell therapy at the NCI will be potentially eligible. EXCLUSION CRITERIA: - Patients who are receiving any other investigational agents. - Patients on any anticoagulants except aspirin - Patients that require urgent therapy due to tumor mass effects or spinal cord compression. - Patients that have active hemolytic anemia. - Patients with second malignancies in addition to multiple myeloma are not eligible if the second malignancy has required treatment within the past 3 years or is not in complete remission.
