Inotuzumab Ozogamicin and Post-Induction Chemotherapy in Treating Patients With High-Risk B-ALL, Mixed Phenotype Acute Leukemia, and B-LLy
This phase III trial studies whether inotuzumab ozogamicin added to post-induction chemotherapy for patients with high-risk B-cell acute lymphoblastic leukemia (B-ALL) improves outcomes. This trial also studies the outcomes of patients with mixed phenotype acute leukemia (MPAL) ...

Protocol Description
A Phase 3 Randomized Trial of Inotuzumab Ozogamicin (IND#:133494, NSC#: 772518) for Newly Diagnosed High-Risk B-ALL; Risk-Adapted Post-Induction Therapy for High-Risk B-ALL, Mixed Phenotype Acute Leukemia, and Disseminated B-LLy
The overall goal of this study is to understand whether adding inotuzumab ozogamicin to standard of care chemotherapy maintains or improves outcomes in high-risk B-cell acute lymphoblastic leukemia (HR B-ALL). The first part of the study includes the first two phases of therapy: induction and consolidation. This part will collect information on the leukemia, as well as the effects of the initial treatment, in order to classify patients into post-consolidation treatment groups.
On the second part of this study, patients will receive the remainder of the chemotherapy cycles (interim maintenance I, delayed intensification, interim maintenance II, maintenance), with some patients randomized to receive inotuzumab. Other aims of this study include investigating whether treating both males and females with the same duration of chemotherapy maintains outcomes for males who have previously been treated for an additional year compared to females, as well as to evaluate the best ways to help patients adhere to oral chemotherapy regimens. Finally, this study will be the first to track the outcomes of subjects with disseminated B-cell lymphoblastic leukemia (B LLy) or mixed phenotype acute leukemia (MPAL) when treated with B-ALL chemotherapy.
