A Phase II Study of Inotuzumab Ozogamicin in Children and Young Adults with Recurrent or Persistent B-Cell Acute Lymphoblastic Leukemia


Full Title

A Phase 2 Study of Inotuzumab Ozogamicin (NSC# 772518, IND#133494) in Children and Young Adults with Relapsed or Refractory CD22+ B-Acute Lymphoblastic Leukemia (B-ALL) AALL1621 (CIRB)


Inotuzumab ozogamicin is a drug used to treat adults with B-cell acute lymphoblastic leukemia (ALL) that has come back or continued to grow despite prior therapy. In this study, researchers are evaluating its use in children and young adults with recurrent or persistent B-cell ALL.

Inotuzumab ozogamicin is an antibody attached to a chemotherapy drug. The antibody attaches to a protein on B-cell ALL cells called CD22. Once attached, the chemotherapy enters the cancer cell, causing the cancer cell to die. Inotuzumab ozogamicin is given intravenously (by vein).
