Description

Summary

This phase III trial studies how well blinatumomab works in combination with chemotherapy in treating patients with newly diagnosed, standard risk B-lymphoblastic leukemia or B-lymphoblastic lymphoma with or without Down syndrome. Monoclonal antibodies, such as blinatumomab, may induce changes in the body's immune system and may interfere with the ability of cancer cells to grow and spread. Chemotherapy drugs, such as vincristine, dexamethasone, prednisone, prednisolone, pegaspargase, methotrexate, cytarabine, mercaptopurine, doxorubicin, cyclophosphamide, and thioguanine, 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. Leucovorin decreases the toxic effects of methotrexate. Giving monoclonal antibody therapy with chemotherapy may kill more cancer cells. Giving blinatumomab and combination chemotherapy may work better than combination chemotherapy alone in treating patients with B-ALL. This trial also assigns patients into different chemotherapy treatment regimens based on risk (the chance of cancer returning after treatment). Treating patients with chemotherapy based on risk may help doctors decide which patients can best benefit from which chemotherapy treatment regimens.

Official Title

A Phase 3 Trial Investigating Blinatumomab (NSC# 765986) in Combination With Chemotherapy in Patients With Newly Diagnosed Standard Risk or Down Syndrome B-Lymphoblastic Leukemia (B-ALL) and the Treatment of Patients With Localized B-Lymphoblastic Lymphoma (B-LLy)

Details

PRIMARY OBJECTIVES:

  1. To determine in a randomized manner if the addition of 2 cycles of blinatumomab to standard therapy improves disease-free survival (DFS) in patients with standard risk (SR) B-ALL and higher risk features (SR-High), and patients with standard-risk average (SR-Avg) B-ALL who are negative for minimal residual disease (MRD) by flow cytometry but have detectable or indeterminate MRD as measured by high-throughput sequencing (HTS) at end of induction (EOI).

II. To confirm that boys in the standard-risk favorable (SR-Fav) subset of B-ALL, with or without Down syndrome (DS), will maintain a 5-year DFS of greater than 93% when treated with a standard chemotherapy regimen with a treatment duration of 2 years from the start of interim maintenance I (IM1).

SECONDARY OBJECTIVES:

  1. To describe the DFS for patients with SR-Avg B-ALL who are negative for MRD measured by flow cytometry and HTS at EOI when treated with standard chemotherapy with a treatment duration of 2 years from the start of IM1, regardless of sex.

II. To describe the DFS for patients with standard-risk favorable (SR-Fav) B-ALL when treated with a standard chemotherapy regimen.

III. To determine if patients with DS-High achieve a reduction of treatment-related mortality (TRM) after replacement of intensive elements of standard chemotherapy (omission of anthracyclines in induction, omission of the second month of delayed intensification [DI]) with 3 cycles of blinatumomab.

IV. To describe the DFS characterized by the replacement of intensive elements of standard chemotherapy with 3 cycles of blinatumomab in patients with DS-High B ALL.

  1. To describe the DFS for patients with localized (Murphy stage I and II) B lymphoblastic lymphoma (B-LLy) receiving standard risk B-ALL therapy.

VI. To compare the change in neurocognitive functioning, as measured by the CogState Cognitive Composite, from baseline to end-of-therapy among patients with ALL ages 4- < 10 years at the time of diagnosis between children from poor families (defined as presence of household material hardship [HMH], including either food, housing or energy insecurity) and non-poor families (absence of HMH).

VII. To describe the impact of blinatumomab on caregiver burden and patient/proxy-reported symptoms among a subset of children enrolled in the HMH and neurocognitive outcome study.

VII. To evaluate available peripheral blood (PB) samples at EOI using HTS MRD and compare the results against bone marrow (BM) results.

IX. To evaluate available end of Consolidation (EOC) BM samples using HTS in patients who were Day 29 MRD positive by flow cytometry and who have submitted EOC BM flow cytometry results.

EXPLORATORY OBJECTIVES:

  1. To explore adaptive and innate immune functions and host genetic factors associated with severe infectious complications in children with DS B-ALL.

II. To explore the impact of acute lymphoblastic leukemia (ALL) and its therapy on neurocognitive, functional, and quality of life outcomes in patients with DS and ALL, as measured by caregiver (parent/legal guardian) questionnaires.

III. To define the prevalence of minimal marrow disease (MMD) in B-LLy and to correlate MMD at diagnosis with outcome in patients with B-LLy.

IV. To explore the significance of and genomic landscape of Ig clonal composition in pediatric B-ALL.

  1. To explore the incidence of HTS MRD ≥ 0.01% versus (vs.) HTS MRD < 0.01% in patients with multiparameter flow cytometry defined MRD < 0.01% at end of Induction and genetically characterize those with discordance defined by the 0.01% threshold.

  • Patient has newly diagnosed B-cell ALL, with or without Down syndrome: > 25% blasts on a bone marrow (BM) aspirate;
    • OR if a BM aspirate is not obtained or is not diagnostic of B-ALL, the diagnosis can be established by a pathologic diagnosis of B-ALL on a BM biopsy;
    • OR a complete blood count (CBC) documenting the presence of at least 1,000/uL circulating leukemic cells;
    • OR patient has newly diagnosed B-cell LLy Murphy stages I or II, with or without Down syndrome.
    • Note: For B-LLy patients with tissue available for flow cytometry, the criterion for diagnosis should be analogous to B-ALL. For tissue processed by other means (i.e., paraffin blocks), the methodology and criteria for immunophenotypic analysis to establish the diagnosis of B-LLy defined by the submitting institution will be accepted (diagnostic biopsy for B-LLy must be performed within 14 days prior to enrollment).
  • All patients and/or their parents or legal guardians must sign a written informed consent.
  • All institutional, Food and Drug Administration (FDA), and National Cancer Institute (NCI) requirements for human studies must be met.

  • Patient must not have secondary ALL that developed after treatment of a prior malignancy with cytotoxic chemotherapy. Note: patients with Down syndrome with a prior history of transient myeloproliferative disease (TMD) are not considered to have had a prior malignancy. They would therefore be eligible whether or not the TMD was treated with cytarabine.
  • With the exception of steroid pretreatment or the administration of intrathecal cytarabine, patients must not have received any prior cytotoxic chemotherapy for either the current diagnosis of B ALL or B LLy or for any cancer diagnosed prior to initiation of protocol therapy on AALL1731.
  • For patients receiving steroid pretreatment, the following additional exclusion criteria apply:
    • Non-DS B-ALL patients must not have received steroids for more than 24 hours in the 2 weeks prior to diagnosis without a CBC obtained within 3 days prior to initiation of the steroids.
    • DS and non-DS B-LLy patients must not have received > 48 hours of oral or IV steroids within 4 weeks of diagnosis.
  • Patients who have received > 72 hours of hydroxyurea within 1 week (7 days) prior to the start of systemic protocol therapy.
  • B-ALL patients who do not have sufficient diagnostic bone marrow submitted for APEC14B1 diagnostic testing and who do not have a peripheral blood sample submitted containing > 1,000/uL circulating leukemia cells.
  • Patient must not have acute undifferentiated leukemia (AUL).
  • Non-DS B-ALL patients with central nervous system [CNS]3 leukemia (CNS status must be known prior to enrollment).
    • Note: DS patients with CNS3 disease are eligible but will be assigned to the DS-High B-ALL arm. CNS status must be determined based on a sample obtained prior to administration of any systemic or intrathecal chemotherapy, except for steroid pretreatment.
  • Non-DS B-ALL patients with testicular leukemia. (Note: DS patients with testicular disease are eligible but will be assigned to the DS-High B-ALL arm).
  • For LLy patients, the following additional exclusion criteria apply:
    • T-Lymphoblastic Lymphoma.
    • Morphologically unclassifiable lymphoma.
    • Absence of both B-cell and T-cell phenotype markers in a case submitted as lymphoblastic lymphoma.
    • CNS positive disease or testicular involvement.
    • M2 (5% - 25% blasts) or M3 (> 25% blasts) marrow.
  • Patients with known Charcot-Marie-Tooth disease.
  • Patients with known MYC translocation associated with mature (Burkitt) B-cell ALL, regardless of blast immunophenotype.
  • Patients requiring radiation at diagnosis.
  • Female patients who are pregnant since fetal toxicities and teratogenic effects have been noted for several of the study drugs. A pregnancy test is required for female patients of childbearing potential.
  • Lactating females who plan to breastfeed their infants.
  • Sexually active patients of reproductive potential who have not agreed to use an effective contraceptive method for the duration of their study participation.
