Genetically-Modified Immune Cells (C7R-expressing EBVSTs) for the Treatment of Relapsed or Refractory EBV-Positive Lymphoma and T/Natural Killer Lymphoproliferative Disorder, the CILESTE study

Trial Status: active

This phase I trial tests the safety, side effects, and best dose of genetically-modified immune cells (C7R-expressing Epstein-Barr virus-specific T cells [EBVSTs]) in treating patients with EBV-positive Hodgkin lymphoma, non-Hodgkin lymphoma, and T/natural killer lymphoproliferative disorder that has come back (relapsed) or has not responded to previous treatment (refractory). EBV is found in the cancer cells of up to half the patients with Hodgkin's and non-Hodgkin lymphoma, suggesting that the EBV plays a role in causing lymphoma. The cancer cells and some immune system cells infected by EBV are able to hide from the body's immune system and escape destruction. If T cells are able to last longer in the body, they may have a better chance of killing EBV and EBV infected cancer cells. 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 on the patient’s cancer cells is added to the T cells in the laboratory. Therefore, adding a new gene to the EBV T cells, called C7R, may cause the T cells to live longer to help kill EBV cancer cells.
