Inotuzumab Ozogamicin in Treating Younger Patients With B-Lymphoblastic Lymphoma or Relapsed or Refractory CD22 Positive B Acute Lymphoblastic Leukemia

ID#: NCT02981628

Age: 1 year - 21 years

Gender: All

Healthy Subjects: No

Study Phase: Phase 2

Recruitment Status: Recruiting

Start Date: June 05, 2017

End Date: December 31, 2024

Summary: This phase II trial studies how well inotuzumab ozogamicin works in treating younger patients with B-lymphoblastic lymphoma or CD22 positive B acute lymphoblastic leukemia that has come back (relapsed) or does not respond to treatment (refractory). Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a toxic agent called ozogamicin. Inotuzumab attaches to CD22 positive cancer cells in a targeted way and delivers ozogamicin to kill them.

- Patients must have B-ALL, or previously diagnosed B lymphoblastic lymphoma (B-LL), with >= 5% (M2 or M3) bone marrow blasts with or without extramedullary disease

- There have been no human studies of inotuzumab ozogamicin in pregnant women and no reports of exposure in utero; based on nonclinical safety studies, inotuzumab ozogamicin has the potential to impair human male and female fertility and to adversely affect human embryo fetal development; women of childbearing potential should be advised to avoid becoming pregnant while receiving inotuzumab ozogamicin; there is no information regarding the presence of inotuzumab ozogamicin in human milk, the effects on the breast-fed infant, or the effects on milk production; because of the potential for adverse reactions in breast-fed infants, women should not breast-feed during treatment with inotuzumab ozogamicin and for at least 2 months after the final dose
