Genetically Engineered Cells (DuoCAR20.19.22-D95) for the Treatment of Relapsed or Refractory B-Cell Cancers

Trial Status: active

This phase I trial that tests the safety, side effects and best dose of DuoCAR20.19.22-D95 and how well it works in treating patients with B-cell cancers that have come back after a period of improvement (relapsed) or that have 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 CD19, CD20, and CD22, 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. Giving chemotherapy, such as fludarabine and cyclophosphamide, before a CAR T-cell infusion helps lower the activity of the T cells in the body and prepares the body to receive the new T cells. DuoCAR20.19.22-D95 may be safe, tolerable, and/or effective in treating patients with relapsed or refractory B-cell cancers.
