iC9-CAR.CSPG4 T-Cells for the Treatment of Patients with Recurrent or Refractory Head and Neck Squamous Cell Carcinoma
This phase I trial tests the safety, side effects, best dose and effectiveness of iC9-CAR.CSPG4 T cells in treating patients with head and neck squamous cell carcinoma (HNSCC) that has come back after a period of improvement (recurrent) or that has not responded to previous treatment (refractory). Chimeric antigen receptor (CAR) T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient’s blood. Then the gene for a special receptor that binds to a certain protein, such as chondroitin sulfate proteoglycan 4 (CSPG4), on the patient’s cancer cells is added to the T cells in the laboratory. The special receptor is called a CAR. Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. CSPG4, an antigen that is expressed on the surface of the cell in certain types of head and neck cancers, and is not expressed on normal cells. iC9-CAR.CSPG4 T cells is CAR T-cell therapy that attack cancer cells that express the CSPG4 antigen. iC9-CAR.CSPG4 T cells may be safe, tolerable and/or effective in treating patients with recurrent or refractory HNSCC.

OUTLINE: This is a dose escalation study of iC9-CAR.CSPG4 T cells followed by a dose-expansion study.
CELL PROCUREMENT: Patients undergo blood collection or apheresis and may receive standard of care bridging therapy prior to lymphodepleting chemotherapy.
TREATMENT: Patients receive lymphodepleting chemotherapy consisting of cyclophosphamide intravenously (IV) and fludarabine IV once daily for 3 days prior to CAR T-cell infusion. Patients receive iC9-CAR.CSPG4 T cells IV on week 0 day 1. Patients with severe toxicities may receive rimiducid IV over 2 hours on study. Patients also undergo blood sample collection, tumor biopsy, computed tomography (CT) scan, magnetic resonance imaging (MRI), positron emission tomography (PET) scan or ultrasound throughout study, and buccal sample collection during screening. Additionally, patients may undergo lumbar puncture for cerebrospinal fluid (CSF) sample collection on study.
After completion of study treatment, patients are followed up at weeks 1, 2, 3, 4, and 6, then at months 3, 6, 9, and 12, then periodically for up to 15 years.
