AALL1731: This Phase III trial is evaluating how well targeted therapy (blinatumomab) works in combination with chemotherapy in treating people with newly diagnosed, standard risk B-lymphoblastic leukaemia or B-lymphoblastic lymphoma.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)

Exclusion

• 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.
