CLINICAL TRIAL / NCT03150693

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) III. To determine the safety and tolerability of a reduced dose of inotuzumab ozogamicin and two cycles of blinatumomab added to the pediatric-inspired regimen of CALGB 10403 (Pilor cohort). 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 timepoints with LDA signature. II. To evaluate the influence of MRD status (detectable 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, sex 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, 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 complete response (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 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.
