About this study
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.

You may qualify if…
- ✓ Patients must be \>= 1 year and \< 22 years of age at the time of enrollment
- ✓ 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
- ✓ NOTE: Relapsed patients previously diagnosed with B-lymphoblastic lymphoma (B-LL) are eligible if they have an M2 or M3 marrow at the time of enrollment on this study
- ✓ Patients with ALL or B-LL who have M2 morphology must have local confirmatory testing showing \>= 5% blasts by flow cytometry, fluorescence in situ hybridization (FISH) testing or other molecular method
- ✓ Leukemic blasts must demonstrate surface expression of CD22 at the time of relapse by local/institutional flow cytometry of a bone marrow aspirate sample; (assessment of CD22 using a bright fluorophore such as phycoerythrin \[PE\] is strongly recommended)
- ✓ In the case of an inadequate aspirate sample (dry tap) or if bone marrow aspirate is unable to be performed due to patient clinical status, flow cytometry of peripheral blood specimen may be substituted if the patient has at least 1,000/uL circulating blasts; alternatively, CD22 expression may be documented by immunohistochemistry of a bone marrow biopsy specimen
- ✓ Patients with one of the following:
- ✓ Second or greater relapse;
You may not qualify if…
- ✕ Patients with any prior history of SOS irrespective of severity
- ✕ Patients with isolated central nervous system (CNS), testicular, or any other extramedullary site of relapse
- ✕ Patients who have been previously treated with inotuzumab ozogamicin
- ✕ Patients who have previously received HSCT (Cohort 2 only)
- ✕ Patients with Down syndrome (Cohort 2 only)
- ✕ History of allergic reaction attributed to compounds of similar or biologic composition to inotuzumab ozogamicin or other agents in the study
- ✕ Note: Patients with history of allergy to pegaspargase/calaspargase pegol are eligible for enrollment on Cohort 2 if Erwinia formulation of asparaginase can be obtained
- ✕ Patients with active optic nerve and/or retinal involvement are not eligible; patients who are presenting with visual disturbances should have an ophthalmologic exam and, if indicated, a magnetic resonance imaging (MRI) to assess optic nerve or retinal involvement
