In The Literature: Using a Patient's Immune Cells to Treat Metastatic Cholangiocarcinoma
Researchers identified tumor-infiltrating CD4+ T cells specific for a mutated antigen expressed by a tumor from a patient with metastatic cholangiocarcinoma. Infusion of this patient with an expanded-population, mutation-specific T cell resulted in tumor regression and stabilization of disease.
Limited evidence exists that humans mount a mutation-specific T cell response to epithelial cancers. We used a whole-exomic-sequencing-based approach to demonstrate that tumor-infiltrating lymphocytes (TIL) from a patient with metastatic cholangiocarcinoma contained CD4+ T helper 1 (T
1) cells recognizing a mutation in erbb2 interacting protein (ERBB2IP) expressed by the cancer.
After adoptive transfer of TIL containing about 25% mutation-specific polyfunctional T
1 cells, the patient achieved a decrease in target lesions with prolonged stabilization of disease. Upon disease progression, the patient was retreated with a >95% pure population of mutation-reactive T
1 cells and again experienced tumor regression. These results provide evidence that a CD4+ T cell response against a mutated antigen can be harnessed to mediate regression of a metastatic epithelial cancer.
