Chemoimmunotherapy With Epratuzumab in Relapsed Acute Lymphoblastic Leukemia (ALL)

Not Recruiting

Trial ID: NCT00098839


This Phase II trial is studying how well giving epratuzumab together with an established chemotherapy platform works in treating young patients with relapsed acute lymphoblastic leukemia. Monoclonal antibodies, such as epratuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Chemotherapy drugs work in different ways to stop the growth of cancer cells, either by killing them or by stopping them from dividing. Giving monoclonal antibody therapy in combination chemotherapy may kill cancer cells more effectively.
