Summary

This phase I/II trial studies the side effects of gene-modified immune cells (FH-MCVA2TCR) and to see how well they work in treating patients with Merkel cell cancer that has spread to other parts of the body (metastatic) or that cannot be removed by surgery (unresectable). Placing a gene that has been created in the laboratory into immune cells may improve the body's ability to fight Merkel cell cancer.

Detailed description

OUTLINE: This is a dose escalation study of FH-MCVA2TCR autologous T-cells. Patients receive interferon gamma-1b subcutaneously (SC) on study. Patients receive FH-MCVA2TCR T-cells intravenously (IV) over 60-120 minutes. Beginning 14 days after receiving FH-MCVA2TCR T-cells, patients also receive standard of care avelumab IV over 1 hour every 2 weeks for 1 year or pembrolizumab IV over 30 minutes every 3 weeks for 1 year in the absence of disease progression or unacceptable toxicity. Patients with partial response or stable disease may then receive an additional cycle of FH-MCVA2TCR T-cells. After completion of study treatment, patients are followed up periodically for up to 15 years.
