Genetically Modified T Cells in Treating Patients With Stage III-IV Non-small Cell Lung Cancer or Mesothelioma

Published: October 5, 2016

Primary Outcome Measures

  • Evidence and nature of toxicity based on the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 [ Time Frame: Up to 6 months after the first T cell infusion ] [ Designated as safety issue: Yes ]
  • Feasibility of naive T cell (TN) and central memory T cell (TCM) subsets, measured as the proportion of patients for which T cells are successfully generated and infused and whether only TN or TCM could be generated [ Time Frame: Up to 4 weeks ] [ Designated as safety issue: No ]
    A simple estimate of the proportion along with its 95% confidence interval will be used.
  • Persistence of transduced T cells [ Time Frame: Up to 15 years ] [ Designated as safety issue: No ]
    In vivo persistence of cells generated from the TN subset with cells generated from the TCM subset will be directly compared within each patient by high throughput TCRbeta sequencing. The one-sample T test will be used to assess the difference in mean persistence between groups, in which the outcome for each patient is the time to disappearance of infused cytotoxic T lymphocytes.

Secondary Outcome Measures

  • Frequency of transferred T cells at biopsied tumor sites between the Tn and Tcm groups [ Time Frame: Up to 15 years ] [ Designated as safety issue: No ]
  • Functional capacity of transferred cells, measured by production of intracellular cytokines [ Time Frame: Up to 15 years ] [ Designated as safety issue: No ] Tetramer+ cells from peripheral blood, if detectable and available in sufficient number, evaluated for production of intracellular cytokines including interferon-gamma (IFN-γ), tumor necrosis factor alpha (TNF-α), and IL-2. Intranuclear Ki-67 expression assessed on recovered tetramer+ T cells. Based on available numbers, ex vivo proliferative capacity after infusion assessed by labeling cells with carboxyfluorescein succinimidyl ester dye and measuring dilution in response to peptide stimulation. Phenotype of tetramer+ antigen-specific cells assessed using established immunophenotyping panels.
  • TTP based on RECIST criteria and immune-related response criteria [ Time Frame: 3 months after last infusion ] [ Designated as safety issue: No ]
    The potential efficacy of the infused cells will be assessed and the substrate cell (TN or TCM) that is most effective based on the TTP of patients who have persisting TN cells to that of patients who have persisting TCM cells 3 months after the last infusion will be determined.

DETAILED DESCRIPTION

Primary Objectives
Determine the safety, and potential toxicities associated with treating patients with metastatic NSCLC and mesothelioma with polyclonal autologous central memory and naïve cluster of differentiation (CD)8+ T cells that have been transduced to express a WT1-specific T-cell receptor (TCR) (Arm 1 and Arm 2).
Determine the feasibility of treating patients with metastatic NSCLC and mesothelioma with polyclonal autologous central memory and naïve CD8+ T cells that have been transduced to express a WT1-specific TCR (Arm 1 and Arm 2).
Determine and compare the in vivo persistence in blood and tumor of transferred polyclonal autologous central memory and naïve CD8+ T cells that have been transduced to express a WT1-specific TCR (Arm 1 and Arm 2).
Secondary Objectives
Determine the antitumor efficacy for patients with metastatic NSCLC and mesothelioma (Arm 1), as measured by time to progression (TTP) based on the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria.
Determine the in vivo functional capacity of adoptively transferred polyclonal autologous CD8+ T cells that have been transduced to express a WT1-specific TCR, and assess the acquisition of phenotypic characteristics associated with T cell exhaustion (Arm 1 and Arm 2).
Determine the migration to tumor sites of adoptively transferred polyclonal autologous CD8+ T cells that have been transduced to express a WT1-specific TCR (Arm 2).
Evaluate the tumor response and T cell infiltration in tumors of patients with stage IIIA NSCLC treated in the neo-adjuvant setting.
