Description

Summary

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), and B-lymphoblastic lymphoma (B-LLy) when treated with ALL therapy without inotuzumab ozogamicin. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a type of chemotherapy called calicheamicin. Inotuzumab attaches to cancer cells in a targeted way and delivers calicheamicin to kill them. Other drugs used in the chemotherapy regimen, such as cyclophosphamide, cytarabine, dexamethasone, doxorubicin, daunorubicin, methotrexate, leucovorin, mercaptopurine, prednisone, thioguanine, vincristine, and pegaspargase work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This trial will also study the outcomes of patients with mixed phenotype acute leukemia (MPAL) and disseminated B lymphoblastic lymphoma (B-LLy) when treated with high-risk ALL chemotherapy. The overall goal of this study is to understand if 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 girls, 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.

Official Title

A Phase 3 Randomized Trial of Inotuzumab Ozogamicin (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

Details

PRIMARY OBJECTIVE:

  1. To determine in a randomized manner if the addition of 2 blocks of inotuzumab ozogamicin to modified Berlin-Frankfurt-Munster (mBFM) chemotherapy will improve 5-year disease-free survival (DFS) in children and young adults with high-risk B-cell acute lymphoblastic leukemia (HR B-ALL).

SECONDARY OBJECTIVES:

  1. To describe the 5-year DFS for a favorable risk subset of National Cancer Institute (NCI) HR B-ALL (HR-Fav) when treated with mBFM chemotherapy with a single high-dose methotrexate (HD-MTX) interim maintenance (IM) phase and treatment duration of 2 years from the start of IM regardless of sex.

II. To determine the toxicity and tolerability of inotuzumab ozogamicin integrated into the mBFM chemotherapy backbone in HR B-ALL.

III. To describe the 5-year event-free survival (EFS) for patients with mixed phenotype acute leukemia (MPAL) receiving mBFM HR B-ALL therapy that includes a second IM phase with Capizzi escalating intravenous (IV) methotrexate (MTX) without leucovorin rescue plus pegaspargase (C-MTX).

IV. To describe the 5-year EFS for patients with disseminated (Murphy stage III-IV) B-cell lymphoblastic lymphoma (B-LLy) receiving mBFM HR B-ALL therapy that includes a second IM phase with C-MTX.

EXPLORATORY OBJECTIVES:

  1. To describe the therapy administered, disease response, and survival outcomes of patients with MPAL who come off protocol therapy due to poor disease response to ALL therapy either during Induction, at end of induction (EOI), or at end of consolidation (EOC).

II. To define the prevalence and significance of minimal marrow disease (MMD) at diagnosis and bone marrow minimal residual disease (MRD) at EOI in disseminated B-LLy.

III. To determine the impact of proposed adherence-enhancing interventions, IP (intervention package as used in ACCL1033) versus (vs.) iIP (intensified intervention package) vs. pIP (patient/parent-established intervention package), on adherence to oral 6 mercaptopurine in children and young adults with ALL.

OUTLINE: All patients receive the same Induction and Consolidation chemotherapy. Patients with HR-Fav B-ALL are assigned to Arm I. Patients with HR B-ALL are randomized to Arm II or III. Patients with MPAL are assigned to Arm IV, and patients with B-LLy are assigned to Arm V.
