Brief Summary

This phase I trial studies the highest possible dose of memory enriched T cells that can be given following standard stem cell transplant before unmanageable side effects are seen in patients with B-cell non-Hodgkin lymphoma that has returned after previous treatment. A T cell is a type of immune cell that can recognize and kill abnormal cells of the body. Memory enriched T cells will be made from a patient's own T cells that are genetically modified in a laboratory. This means that the T cells are changed by inserting additional pieces of deoxyribonucleic acid (genetic material) into the cell to make it recognize and kill lymphoma cells. Memory enriched T cells may kill the cells that are not killed by stem cell transplant and may lower the chances of the cancer recurring.

Detailed Description

PRIMARY OBJECTIVES: I. To assess the safety and determine the maximum tolerated dose (MTD) of each cellular immunotherapy product, cluster of differentiation (CD)19R (EQ) 28 zeta/truncated human epidermal growth factor receptor (EGFRt) + central memory T cell (Tcm) (Arm 1) and CD19R(EQ)28zeta/EGFRt+ naive memory T cell (TN/MEM) (Arm 2), in conjunction with a standard myeloablative autologous hematopoietic stem cell transplant (HSCT) for patients with high-risk intermediate or high grade B-lineage non-Hodgkin lymphomas.

SECONDARY OBJECTIVES: I. To determine the tempo, magnitude, and duration of engraftment of the transferred T cell product as it relates to the number of cells infused.

II. To study the impact of this therapeutic intervention on the development of normal CD19+ B-cell precursors in the bone marrow as a surrogate for the in vivo effector function of transferred autologous CD19R(EQ)28zeta/EGFRt+ Tcm or TN/MEM.

OUTLINE: This is a dose-escalation study. Patients are assigned to 1 of 2 arms. ARM 1: Patients receive autologous CD19CAR-CD28-CD3zeta-EGFRt-expressing TCM-enriched T cells intravenously (IV) over 10 minutes on day 2 or 3 following HSCT. ARM 2: Patients receive autologous CD19CAR-CD28-CD3zeta-EGFRt-expressing TN/MEM-enriched T cells IV over 10 minutes on day 2 or 3 following HSCT. Patients who experience disease progression and have not experienced serious treatment-related toxicities at greater than or equal to 100 days post T cell infusion will be allowed to receive an optional second T cell infusion.

After completion of study treatment, patients are followed up within 18-24 hours, then 18-72 hours, weekly for 1 month, monthly for 1 year, at 18, 24, and 36 months, and then annually thereafter for a minimum of 15 years.

  • City of Hope (COH) pathology review confirms that research participant's diagnostic material is consistent with history of intermediate or high grade B-cell NHL (e.g., DLBCL, MCL, or transformed NHL)
  • Negative serum pregnancy test for women of child-bearing potential
  • Research participant has an indication to be considered for autologous stem cell transplantation

ELIGIBILITY CRITERIA AT TIME OF INFUSION OF GENETICALLY MODIFIED AUTOLOGOUS T CELLS:

  • Research participant has a released cryopreserved T cell product
  • Research participant did not have evidence of disease progression after salvage therapy and therefore underwent an autologous myeloablative transplantation with hematopoietic progenitor cell autologous (HPC[A]) rescue procedure
  • Not requiring supplemental oxygen or mechanical ventilation, oxygen saturation 90% or higher on room air
  • Not requiring pressor support, not having symptomatic cardiac arrhythmias
  • Lack of acute renal failure/requirement for dialysis, as evidenced by creatinine < 1.6 mg/dL
  • Total bilirubin =< 5.0 mg/dL
  • Research participant without clinically significant encephalopathy/new focal deficits
  • No clinical evidence of uncontrolled active infectious process
Exclusion Criteria
  • Research participants with any uncontrolled illness including ongoing or active infections; research participants with known active hepatitis B or C infection; research participants who are human immunodeficiency virus (HIV) positive based on testing performed within 4 weeks of enrollment; research participants with any signs or symptoms of active infection, positive blood cultures or radiological evidence of infections

  • Research participants receiving any other investigational agents, or concurrent biological, chemotherapy, or radiation therapy

  • Research participants with a history of allergic reactions attributed to compounds of similar chemical or biological composition to cetuximab

  • Research participants with known brain metastases (central nervous system [CNS] involvement either parenchymal or leptomeningeal involvement)

  • Research participants with presence of other active malignancy; however, research participants with history of prior malignancy treated with curative intent and in complete remission are eligible

  • Failure of research participant to understand the basic elements of the protocol and/or the risks/benefits of participating in this phase I study; a legal guardian may substitute for the research participant

  • History of allogeneic HSCT or prior autologous HSCT

  • Any standard contraindications to myeloablative HSCT per standard of care practices at COH

  • Dependence on corticosteroids

    • Defined as doses of corticosteroids of greater than or equal to 5 mg/day of prednisone or equivalent doses of other corticosteroids
    • Note: topical and inhaled corticosteroids in standard doses and physiologic replacement for subjects with adrenal insufficiency are allowed
  • Currently receiving another investigational agent

  • Active autoimmune disease requiring systemic immunosuppressive therapy

  • Research participants will be excluded, who in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study
