Clinical Trial Summary

This is a phase 1, single-center, open-label study that enrolls adult subjects with extensive stage lung cancer or stage IV non-small cell lung cancer that is platinum-refractory and received PD-1 and/or PD-L1 therapy. The purpose of this study is to test the safety of using a new treatment called autologous T lymphocyte chimeric antigen receptor cells against the GD2 antigen (iC9-GD2.CAR.IL-15 T cells) in subjects with lung cancer. How much (dose) of the iC9-GD2.CAR.IL-15 T cells are safe to use without causing too many side effects and what is the maximum dose that could be tolerated will be studied.

Modified immune cells as an experimental treatment that combines antibodies and T cells will be used. Antibodies are proteins that protect the body from foreign invaders like bacteria. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill viruses and other cells, including tumor cells. Although antibodies and T cells have been used to treat cancer and they both have shown promise, neither alone has been able to cure most patients. This study will combine T cells and antibodies to create a more effective treatment.

The treatment that is being researched in this study is called autologous T lymphocyte chimeric antigen receptor cells targeted against the disialoganglioside (GD2) antigen that expresses Interleukin (IL)-15, and the inducible caspase 9 safety switch (iC9). The short name for this treatment is iC9.GD2.CAR.IL-15 T cells therapy is an experimental therapy and has not been approved by the Food and Drug Administration. There are two steps. In the first step, blood will be collected from the subjects to prepare the iC9-GD2.CAR.IL-15 T cells. T cells will be isolated from the blood and modified to make iC9-GD2.CAR.IL-15. In the second step, the iC9-GD2.CAR.IL-15 T cells produced from the subject's own blood will be administered to the subject.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of participants with adverse event	The number of participants with adverse events (AE)s will be reported as a measure of the safety and tolerability of C9.GD2.CAR.IL-15 T. AEs will be classified and graded according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0.; Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local, or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living (ADL). Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL. Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to AE.	Up to 4 weeks
Primary	Cytokine Release Syndrome (CRS)	CRS will be graded according to the American Society for Transplantation and Cellular Therapy (ASTCT) CRS Consensus Grading.; Grade 1 - Mild (Symptomatic Management): Fever =38^ o C, No hypotension, No hypoxia, Grade 2 - Moderate (Moderate Intervention): Fever =38^ o C, Hypotension not requiring vasopressors, Hypoxia requiring low-flow nasal cannula (=6 L/minute) or blow-by, Grade 3 - Severe (Aggressive Intervention): Fever = 38^ o C , Hypotension requiring a vasopressor with or without vasopressin, Hypoxia requiring high-flow nasal cannula (>6 L/minute), facemask, nonrebreather mask, or Venturi mask, Grade 4 - Life-threatening (Life-sustaining intervention): Fever =38^oC, Hypotension requiring multiple vasopressors (excluding vasopressin), Hypoxia requiring positive pressure (e.g. Continuous positive airway pressure, BiPAP, intubation, mechanical ventilation), Grade 5 - Death: Death.	Up to 4 weeks
Primary	Neurotoxicity	Neurotoxicity will be graded according to the American Society for Transplantation and Cellular Therapy (ASTCT) Immune effector cell-associated neurotoxicity syndrome (ICANS) Consensus Grading criteria.; ICANS grading criteria are outlined in the protocol on a scale from 1 (mild) to 4 (critical) based on the Immune Effector Cell-Associated Encephalopathy (ICE) Score. Grade 1:Score: 7-9 (mild impairment), Grade 2:Score: 3-6 (moderate impairment), Grade 3: Score: 0-2 (severe impairment), Grade 4: Score: Subject in critical condition, and/or obtunded and cannot perform an assessment of tasks.	Up to 4 weeks
Secondary	Identification of Recommended phase 2 dose (RP2D)	The RP2D of iC9-GD2.CAR.IL-15 T-cells will be determined based on the modified 3+3 dose-finding rule based on the protocol. Dose escalation will be performed considering the dose-limiting toxicities (DLTs), dose level (DL) will be increased unless there is no DLT.	Up to 4 weeks
Secondary	Overall Response Rate (ORR)	ORR will be assessed per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) which defines Complete Response (CR) as the disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions. Overall Response Rate (ORR) = number of subjects who achieved CR + number of subjects who achieved PR / total number of subjects who received the study treatment.	Up to 4 weeks
