This phase I trial tests the safety, side effects, and best dose of genetically modified immune cells called iC9-GD2.CAR.IL-15 T cells in treating patients with extensive stage small cell lung cancer (SCLC) or stage IV non-small cell lung cancer (NSCLC). The experimental treatment in this trial combines two different ways the body fights tumors: antibodies and T cells. Antibodies are proteins that protect the body from foreign invaders like bacteria. Antibodies work by attaching to these bacteria or substances, which stops them from growing and causing bad effects in the body. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill viruses and other cells, including tumor cells. Antibodies and T cells have been used to treat cancer. This study will combine T cells and antibodies to create a more effective treatment. The treatment that is being researched in this trial is called autologous T lymphocyte chimeric antigen receptor cells targeted against the disialoganglioside (GD2) antigen that express Interleukin (IL)-15, and the inducible caspase 9 safety switch (iC9). In previous studies, it has been shown that a new gene can be put into T cells to increase their ability to recognize and kill tumor cells. The new gene that is put in the T cells in this trial makes a piece of an antibody called anti-GD2. This antibody floats around in the blood and can detect and stick to tumor cells because they have a substance on the outside of the cells called GD2. For this trial, the anti-GD2 antibody has been changed so instead of floating freely in the blood, it is now joined to the T cells. This combination of T cells and anti-GD2 antibodies is called autologous T lymphocyte chimeric antigen receptor cells targeted against the GD2 antigen (GD2-CAR-T). To improve the fighting power of GD2-CAR-T cells, the study team has added two additional components to the cells. The interleukin-15 (IL-15) gene was added so that the GD2-CAR-T cells can attack cells more efficiently. IL-15 is a chemical that cells use to communicate with one another. Other research using IL-15 in combination with CAR-T cells has shown there is an increase in the body’s ability to allow the CAR-T cells to survive and grow in the body. Lastly, the iC9 gene was added as a ‘stop switch’ so it can stop the activity of the GD2-CAR-T cells if the patient experiences any bad side effects. In this trial, the iC9-GD2.CAR.IL-15 T cells are given to participants after they complete lymphodepletion chemotherapy. Lymphodepletion chemotherapy is a type of chemotherapy given to decrease the number of lymphocytes (white blood cells) in the body. White blood cells in the body can attack the CAR-T cells and stop them from growing and multiplying. Lymphodepletion chemotherapy has been shown to increase the length of time that the modified CAR-T cells survive in the body and have been associated with improved cancer-free survival. The study team believes the combination of anti-GD2 antibody, IL-15, i9C, and T cells (called iC9-GD2.CAR.IL-15 T cells) will be more effective in targeting and destroying cancerous cells than the normal T cells alone.

PRIMARY OBJECTIVE:
I. To evaluate the safety and tolerability of administration of autologous iC9-GD2CAR-CD28-CD3zeta-IL-15-expressing T-lymphocytes (iC9-GD2.CAR.IL-15 T-cells) in adult subjects with extensive stage lung cancer or stage IV non-small cell lung cancer (designated together as ‘incurable lung cancer’).
SECONDARY OBJECTIVES:
I. To identify a recommended phase 2 dose (RP2D) for administration of iC9-GD2.CAR.IL-15 T-cells in adult subjects with incurable lung cancer.
II. To determine the objective response rate (ORR) in adult subjects with incurable lung cancer following lymphodepletion and infusion of iC9-GD2.CAR.IL-15 T-cells.
III. To estimate progression-free survival (PFS) in subjects with incurable lung cancer following lymphodepletion and infusion of iC9-GD2.CAR.IL-15 T-cells.
IV. To determine overall survival (OS) in adult subjects with incurable lung cancer following lymphodepletion and infusion of iC9-GD2.CAR.IL-15 T-cells.
V. To determine duration of response (DOR) in adult subjects with incurable lung cancer following lymphodepletion and infusion of iC9-GD2.CAR.IL-15 T-cells.
VI. To determine duration of benefit in adult subjects with incurable lung cancer following lymphodepletion and infusion of iC9-GD2.CAR.IL-15 T-cells.
VII. To analyze GD2 expression in adult subjects with incurable lung cancer.
EXPLORATORY OBJECTIVES:
I. To evaluate the persistence, expansion, and function of iC9-GD2.CAR.IL-15 T-cells.
II. To measure and compare cytokines and immunophenotypes in the peripheral blood after iC9-GD2.CAR.IL-15 T-cell administration.
III. To measure change in IL-15 levels at baseline and over time in adult subjects treated with iC9-GD2.CAR.IL-15 T-cells.
IV. To evaluate genomic, gene expression, and/or immunological changes in tumor cells and in associated tumor microenvironment before and after iC9-GD2.CAR.IL-15 T-cells.
V. To determine the utility of the safety switch in iC9-GD2.CAR.IL-15 T-cells by allowing for administration of rimiducid (0.4 mg/kg dose) to subjects with >= grade 4 cytokine release syndrome (CRS) or Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS), grade 3 CRS or ICANS that does not improve to grade 0-1 within 72 hours, or experiencing a >= grade 3 non-hematologic or hematologic toxicity (excluding grade 3 electrolyte abnormalities, hyperglycemia, diarrhea or nausea and vomiting and grade 3-4 hematologic toxicity without functional sequelae that do not persist at grade 3-5 for > 7 days).
VI. To determine the safety and tolerability of rimiducid administration to activate the safety switch in iC9-GD2.CAR.IL-15 T-cells.
VII. To determine whether there are correlations between CAR T cell behavior and the integration location of iC9-GD2.CAR-IL-15.
OUTLINE: This is a dose-escalation study of iC9-GD2.CAR.IL-15 T cells.
CELL PROCUREMENT: Patients undergo collection of blood for cell procurement.
LYMPHODEPLETION CHEMOTHERAPY: Patients receive cyclophosphamide intravenously (IV) and fludarabine IV daily for 3 consecutive days.
CELL PRODUCT ADMINISTRATION: Approximately 2-14 days after lymphodepletion chemotherapy, patients receive iC9-GD2.CAR.IL-15 T cells IV over 5-10 minutes on day 1 of week 0 or as a split dose on day 1 week 0 followed by a second dose at least 24 hours later and within 14 days of the first dose. Patients experiencing ICANS or severe or moderate to severe CRS also receive rimiducid IV.
Patients also undergo biopsy, computed tomography (CT) or positron emission tomography (PET)-CT scan, and collection of blood samples throughout the study. Additionally, patients with brain metastases undergo magnetic resonance imaging (MRI) throughout the study.
After completion of study treatment, participants are followed up every 3 months for 1 year, every 6 months from 18 months through year 5, and then annually for up to 15 years post-infusion.
