Laboratory-Treated Autologous Lymphocytes, Aldesleukin, and GM-CSF in Treating Patients With Recurrent, Refractory, or Metastatic Non-Small Cell Lung Cancer

Study Overview
=================
Brief Summary
-----------------
RATIONALE: Giving autologous lymphocytes that have been treated in the laboratory with antibodies may stimulate the immune system to kill tumor cells. Aldesleukin may stimulate the lymphocytes to kill tumor cells. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving laboratory-treated autologous lymphocytes together with aldesleukin and GM-CSF may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of laboratory-treated autologous lymphocytes when given together with aldesleukin and GM-CSF in treating patients with recurrent, refractory, or metastatic non-small cell lung cancer.

Detailed Description
-----------------
OBJECTIVES: Primary Determine the safety and maximum tolerated dose of EGFRBi-armed autologous activated T-cells (ATC) when administered in combination with low-dose aldesleukin and sargramostim (GM-CSF) in patients with recurrent, refractory, or extensive (metastatic) non-small cell lung cancer (NSCLC). Secondary Assess clinical outcome based on tumor responses, overall survival, and progression-free survival. Monitor changes in sera concentrations of the tumor marker in association with EGFRBi-armed ATC administration throughout the study and at time points thereafter in patients with elevated levels of carcinoembryonic antigen (CEA) prior to beginning the study. Monitor patient sera for human anti-mouse antibodies (HAMA). Evaluate immune response, which may reflect immune augmentation in response to EGFRBi-armed ATC infusions, in peripheral blood mononuclear cell (PBMC) samples as well as purified immune cell populations. Investigate proliferation in response to ex vivo stimulation with NSCLC tumor-associated antigens, sera cytokine profiles (Th1 vs Th2), cytotoxicity of patient PBMC, and interferon gamma ELISPOTS as a surrogate marker for assessing generation of EGFR-specific cytotoxic T-lymphocytes (CTL). OUTLINE: Peripheral blood mononuclear cells (PBMCs) are collected by 1 or 2 leukaphereses for the generation of activated T cells (ATCs). The PBMCs are activated with OKT3 (anti-CD3) and expanded in aldesleukin for up to 14 days. The ATCs are then armed with EGFRBi. Patients receive EGFRBi-armed autologous ATCs IV over 30-60 minutes twice weekly for 4 weeks (a total of 8 infusions) in the absence of disease progression or unacceptable toxicity. Patients also receive low-dose aldesleukin subcutaneously (SC) once daily and sargramostim (GM-CSF) SC twice weekly beginning 3 days before the first ATC infusion and continuing for 1 week after the last ATC infusion. After completion of study therapy, patients are followed periodically.
