Inotuzumab Ozogamicin and Blinatumomab With or Without Ponatinib in Treating Patients With Newly Diagnosed, Recurrent, or Refractory CD22-Positive B-Lineage Acute Lymphoblastic Leukemia

Summary

This phase II trial studies how well inotuzumab ozogamicin and blinatumomab with or without ponatinib work in treating patients with CD22-positive B-lineage acute lymphoblastic leukemia that is newly diagnosed, has come back after a period of improvement (recurrent), or does not respond to treatment (refractory). Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a chemotherapy drug, called ozogamicin. Inotuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD22 receptors, and delivers ozogamicin to kill them. Blinatumomab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Ponatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving inotuzumab ozogamicin and blinatumomab with or without ponatinib may be effective in treating patients with newly diagnosed, recurrent or refractory CD22 positive B-lineage acute lymphoblastic leukemia.
