Summary

This phase III trial studies the side effects of inotuzumab ozogamicin and how well it works when given with frontline chemotherapy in treating patients with newly diagnosed B acute lymphoblastic leukemia. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a chemotherapy drug, called ozogamicin. Inotuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD22 receptors, and delivers ozogamicin to kill them. Chemotherapy drugs, such as [intervention], 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. Giving inotuzumab ozogamicin with chemotherapy may work better in treating young adults with B acute lymphoblastic leukemia.

Objectives

PRIMARY OBJECTIVES:
I. To confirm tolerability of the combination regimen with the addition of inotuzumab ozogamicin to the pediatric-inspired regimen of cancer and leukemia group B (CALGB) 10403.
II. To determine whether the addition of inotuzumab ozogamicin significantly improves the event-free survival (EFS) in patients who achieve an induction response achieved with the pediatric-inspired regimen of CALGB 10403, without censoring for transplant. (Phase III)

SECONDARY OBJECTIVES:
I. To determine the impact of inotuzumab ozogamicin on disease-free (DFS) and overall survival (OS) in patients who achieve an induction response.
II. To determine whether the addition of inotuzumab ozogamicin significantly improves the event-free survival (EFS) in patients who achieve an induction response achieved with the pediatric-inspired regimen of CALGB 10403, with censoring for transplant.
III. To determine the impact of inotuzumab ozogamicin on minimal residual disease (MRD) and correlate this with the EFS, DFS and OS.
IV. To determine the prognosis based on patients’ low-density array (LDA) gene signature in terms of EFS, DFS, and OS after treatment with or without inotuzumab ozogamicin when added to the C10403 backbone regimen.
V. To evaluate the toxicity and tolerability of the addition of inotuzumab ozogamicin to the pediatric-inspired regimen of CALGB 10403.

CORRELATIVE SCIENCE OBJECTIVES:
I. To assess both the correlation of MRD post-induction and at sequential time points with LDA signature.
II. To evaluate the influence of MRD status (detectable versus [vs.] not and as a continuous measure) in relation to EFS both in the univariate setting as well as adjusting for other clinical features including initial white blood cell (WBC), ethnicity, gender and age at diagnosis.
III. To evaluate the impact of inotuzumab ozogamicin (inotuzumab) on the kinetics of MRD during treatment with inotuzumab in patients randomized to the experimental treatment arm.
IV. To perform genomic analyses to identify and evaluate the incidence and clinical significance of recurring novel fusion genes including those associated with the BCR-ABL1-like signature and to correlate with MRD status, complete response (CR) rate, EFS and OS.
V. To assess whether rs4958351 is correlated with L-asp allergic reaction in the adolescent and young adult (AYA) population.
VI. To assess the incidence of inherited genetic variants in the GR1A1, CEP72, CPA2, TPMT, NUDT15, GRIN3A, GRIK1, and other genes (which can be found using a whole genome association study [GWAS]), are correlated with increased rates of target toxicities including peripheral neuropathy, hepatotoxicity, pancreatitis, myelosuppression, neurotoxicity, thrombosis, and osteonecrosis, and correlate with treatment discontinuation and other clinical response parameters including CR rate, EFS, and OS.
VII. To evaluate asparaginase pharmacokinetics in adolescents and young adults, and investigate its correlation with toxicities and treatment outcomes.
VIII. To investigate the effect of anti-polyethylene glycol (PEG) and anti-agouti signaling protein (ASP) antibodies (PEG-ASP) on ASP enzyme activity.
IX. To measure adherence to oral 6 mercaptopurine (MP) and methotrexate in AYAs with acute lymphoblastic leukemia (ALL) and to examine sociodemographic and behavioral determinants of adherence.
X. To determine the impact of adherence on risk of relapse among AYAs with ALL.
XI. To correlate specific karyotype groups (normal or various primary and secondary chromosomal abnormalities) with clinical and laboratory parameters.
XII. To correlate specific karyotype groups with response rates, response duration, survival, and cure in patients treated on this protocol.
XIII. To correlate specific karyotype groups with MRD.
XIV. To determine karyotype changes at relapse and the influence of the type of change (or no change) in karyotype at relapse.
XV. To define the success rate, analytical performance, and diagnostic yield of ChromoSeq vs. conventional G-banded karyotyping and fluorescence in situ hybridization (FISH) for B-ALL patients in a multicenter setting.
XVI. To determine whether ChromoSeq accurately identifies the poor risk Ph-like B-ALL subtype.
