Genetically Modified T-cells (CMV-Specific CD19-CAR T-cells) Plus a Vaccine (CMV-MVA Triplex) Following Stem Cell Transplantation for the Treatment of Intermediate or High Grade B-cell Non-Hodgkin Lymphoma

Recruiting now · Phase 1

Conditions studied: B-Cell Non-Hodgkin Lymphoma, Diffuse Large B-Cell Lymphoma, Mantle Cell Lymphoma, Recurrent B-Cell Non-Hodgkin Lymphoma, Recurrent Diffuse Large B-Cell Lymphoma, Recurrent Mantle Cell Lymphoma, Recurrent Transformed Non-Hodgkin Lymphoma, Transformed Non-Hodgkin Lymphoma

In brief

This phase I trial studies the safety and side effects of cytomegalovirus (CMV) specific CD19-chimeric antigen receptor (CAR) T-cells along with the CMV-modified vaccinia Ankara (MVA) triplex vaccine following a stem cell transplant in treating patients with high grade B-cell non-Hodgkin lymphoma. CAR T-cells are a type of treatment in which a patient's T-cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T-cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T-cells are grown in the laboratory and given to the patient by infusion. Vaccines such as CMV-MVA triplex are made from gene-modified viruses and may help the body build an effective immune response to kill cancer cells. Giving CMV-specific CD19-CAR T-cells plus the CMV-MVA triplex vaccine following a stem cell transplant may help prevent the cancer from coming back.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Documented informed consent of the participant and/or legally authorized representative.
• Assent, when appropriate, will be obtained per institutional guidelines
• Agreement to allow the use of archival tissue from diagnostic tumor biopsies.
• If unavailable, exceptions may be granted with study PI approval
• Note: For research participants who do not speak English, a short form consent may be used with a City of Hope (COH) certified interpreter/translator to proceed with screening and leukapheresis, while the request for a translated full consent is processed
• Age >= 18 years
• Karnofsky performance status (KPS) >= 70
• Life expectancy >= 16 weeks at the time of enrollment
• Patients with an indication to be considered for HSCT, who are diagnosed with intermediate or high-grade B cell NHL (e.g., diffuse large B-cell lymphoma [DLBCL], mantle cell lymphoma [MCL], or transformed NHL) in first relapse after achieving complete remission (CR) or did not achieve CR after a first line therapy
• Note: COH pathology review should confirm that research participant's diagnostic material is consistent with history of intermediate or high-grade CD19+ malignancy
• No known contraindications to myeloablative HSCT, leukapheresis, steroids or tocilizumab, smallpox vaccine and any other modified vaccinia Ankara (MVA)-based vaccines
• Patient must be CMV seropositive
• Total serum bilirubin =< 2.0 mg/dL
• Participants with Gilbert syndrome may be included if their total bilirubin is =< 3.0
• Aspartate aminotransferase (AST) < 2.5 x upper limits of normal (ULN)
• Alanine aminotransferase (ALT) < 2.5 x ULN
• Serum creatinine =< 2.5 x ULN or estimated creatinine clearance of >= 40 mL/min per the Cockcroft-Gault formula, and the participant is not on hemodialysis
• Absolute neutrophil count >= 1000/uL (Transfusions and growth factors must not be used to meet this requirement at initial screening)
• Hemoglobin (Hb) >= 8 g/dl (Transfusions and growth factors must not be used to meet this requirement at initial screening)
• Platelet count >= 50,000/uL (>= 30,000/uL if bone marrow plasma cells are => 50 percent of cellularity) (Transfusions and growth factors must not be used to meet this requirement at initial screening)
• Left ventricular ejection fraction >= 45 percent within 8 weeks before enrollment
• Oxygen (O2) saturation > 92% without requiring supplemental oxygen
• Women of childbearing potential (WOCBP): negative urine or serum pregnancy test
• If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
• Agreement by females and males of childbearing potential to use an effective method of birth control or abstain from heterosexual activity for the course of the study through at least 6 months after the last dose of protocol therapy.

You may not qualify if…

• Prior autologous/allogeneic stem cell transplant
• Growth factors within 14 days of enrollment
• Platelet transfusions within 7 days of enrollment
