PHASE1

Genetically Engineered Cells (Anti-CD19/CD20/CD22 CAR T-cells) for the Treatment of Relapsed or Refractory Lymphoid Malignancies

Sponsor: Sumithira Vasu

View on ClinicalTrials.gov

Summary

This phase I trial tests the safety, side effects and best infusion dose of genetically engineered cells called anti-CD19/CD20/CD22 chimeric antigen receptor (CAR) T-cells following a short course of chemotherapy with cyclophosphamide and fludarabine in treating patients with lymphoid cancers (malignancies) that have come back (recurrent) or do not respond to treatment (refractory). Lymphoid malignancies eligible for this trial are: non-Hodgkin lymphoma (NHL), acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), and B-prolymphocytic leukemia (B-PLL). T-cells (a type of white blood cell) form part of the body's immune system. CAR-T is a type of cell therapy that is used with gene-based therapies. CAR T-cells are made by taking a patient's own T-cells and genetically modifying them with a virus so that they are recognized by a group of proteins called CD19/CD20/CD22 which are found on the surface of cancer cells. Anti-CD19/CD20/CD22 CAR T-cells can recognize CD19/CD20/CD22, bind to the cancer cells and kill them. Giving combination chemotherapy helps prepare the body before CAR T-cell therapy. Giving CAR-T after cyclophosphamide and fludarabine may kill more tumor cells.
