Gene Therapy Study for B-Cell Acute Lymphoblastic Leukemia

The main purpose of this study is to test the safety of a gene therapy. Scientists have created a gene in the laboratory that could be transferred to the cells in the body. This gene carries information to tell the cells how to make an antibody (protein). The antibody (protein) is very similar to an antibody (protein) called blinatumomab. Blinatumomab is an FDA-approved treatment for relapsed or refractory B-cell ALL. This gene therapy is not approved by the FDA, therefore is it experimental. This study tests different doses of the gene therapy to see which dose is safer in people since it has not been tested in people yet.
