COG AALL1621 - 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)
This phase II trial studies how well inotuzumab ozogamicin works in treating younger patients (≥1 year and < 22 years ) with CD22 positive B acute lymphoblastic leukemia that has come back or does not respond to treatment. Immunotoxins, such as inotuzumab ozogamicin, are antibodies linked to a toxic substance and may help find cancer cells that express CD22 and kill them without harming normal cells.
• 1 to 21 years old
• must have B Acute Lymphoblastic Leukemia (B-ALL), or previously diagnosed B lymphoblastic lymphoma (B-LL)
• Patients with one of the following: Second or greater relapse; Primary refractory disease with at least 2 prior induction attempts; First relapse refractory to at least one prior re-induction attempt; OR Any relapse after HSCT (Cohort 1 ONLY)
