PRIMARY OBJECTIVE:
I. To compare in a randomized manner the 5-year disease-free survival (DFS) for children
and young adults with High Risk (HR) B-cell acute lymphoblastic leukemia (B-ALL) treated
with modified Berlin-Frankfurt-Munster (mBFM) chemotherapy without delayed
intensification (DI) part 2, but with the addition of two blocks of inotuzumab
ozogamicin, versus those treated with full mBFM chemotherapy backbone including DI Part 2
without the addition of inotuzumab ozogamicin.
SECONDARY OBJECTIVES:
I. 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 including toxicity experienced during phases
of therapy subsequent to inotuzumab ozogamicin.
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 intravenous (IV) methotrexate without leucovorin rescue plus pegaspargase or
calaspargase pegol (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:
I. 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 on adherence
to oral 6-mercaptopurine in patients with ALL.
