Combination Chemotherapy With or Without Blinatumomab in Treating Patients With Newly Diagnosed BCR-ABL-Negative B Lineage Acute Lymphoblastic Leukemia

• Status: Active, not recruiting
• Trial end date: 2022-06-30
• Target enrollment: 0
• Participant gender: All

Summary

This randomized phase III trial studies combination chemotherapy with blinatumomab to see how well it works compared to induction chemotherapy alone in treating patients with newly diagnosed breakpoint cluster region (BCR)-c-abl oncogene 1, non-receptor tyrosine kinase (ABL)-negative B lineage acute lymphoblastic leukemia. Drugs used in chemotherapy 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. Immunotherapy with monoclonal antibodies, such as blinatumomab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is not yet known whether combination chemotherapy is more effective with or without blinatumomab in treating newly diagnosed acute lymphoblastic leukemia.

Criteria

Inclusion Criteria:

• PRE-REGISTRATION

• Diagnostic bone marrow and peripheral blood specimens must be submitted for immunophenotyping and selected molecular testing, and the establishment of BCR/ABL status; testing will be performed by the Eastern Cooperative Oncology Group (ECOG)-American College of Radiation Imaging Network (ACRIN) Leukemia Translational Research Laboratory (LTRL) and reported to the institution

• NOTE: IT IS ESSENTIAL THAT A SAMPLE CONTAINING SUFFICIENT BLAST CELLS BE SUBMITTED TO THE ECOG-ACRIN LTRL AT BASELINE SO THAT SUBSEQUENT BONE MARROW ASSESSMENTS OF MRD CAN BE DONE; IN ADDITION TO ALLOWING THE LTRL TO CONFIRM ELIGIBILITY BASED ON BLAST CELL IMMUNOPHENOTYPE AND BCR/ABL STATUS, IT IS ALSO IMPERATIVE THAT AN ADEQUATE NUMBER OF BLASTS BE BANKED FOR ANALYSIS BY DRS MULLIGHAN/WILLMAN. WITHOUT ADEQUATE BASELINE SAMPLES, PATIENTS WILL NOT BE ABLE TO BE TREATED AND RANDOMIZED ON THIS PROTOCOL; IF A BONE MARROW ASPIRATE IS NOT AVAILABLE FOR LTRL SUBMISSION AT BASELINE, IT IS IMPERATIVE THAT DR PAIETTA FROM THE LTRL IS CALLED TO DISCUSS THE PERIPHERAL BLOOD WBC AND BLAST COUNT BEFORE BLOOD ONLY IS SUBMITTED

• NOTE: Hydroxyurea can be given for up to 5 days prior to initiation of protocol therapy for control of leukocyte count and/or other symptoms or signs; corticosteroids can be given after pre-registration to the protocol and submission of baseline marrow and blood samples for control of leukocyte count and/or other symptoms or signs prior to initiation of protocol therapy if needed; if corticosteroids are given prior to pre-registration, contact the study chair as the patient may still be eligible to participate

• INDUCTION ELIGIBILITY CRITERIA-STEP 1

• New diagnosis of B lineage ALL must be made upon bone marrow or peripheral blood immunophenotyping; cases with myeloid antigen expression, but unequivocal lymphoid immunophenotype, are eligible

• Negativity for the Philadelphia chromosome must be established by conventional cytogenetics, fluorescence in situ hybridization (FISH) and/or polymerase chain reaction (PCR); patients who are negative for the Philadelphia chromosome by conventional cytogenetics must have FISH or PCR performed for BCR/ABL to exclude occult translocations

• Cytogenetic analysis must be performed from diagnostic bone marrow (preferred) or if adequate number of circulating blasts from peripheral blood; FISH testing for common B-lineage ALL abnormalities including t(9;22) (BCR/ABL1), t(12;21) (ETS-variant gene 6 [ETV6]/runt-related transcription factor 1 [RUNX1]), t(1;19) (pre-B-cell leukemia homeobox 1 [PBX1]/transcription factor 3 [TCF3]), +4,+10,+17, (centromeric [Cen]4/Cen10/Cen17), t(11q23;var), (myeloid/lymphoid or mixed lineage leukemia [MLL]), deletion (del)(9p) (cyclin-dependent kinase inhibitor 2A [CDKN2A]/Cen9), and t(14;var) (immunoglobulin heavy chain [IGH] is encouraged); if there are few or no circulating blasts and an adequate marrow sample cannot be obtained for cytogenetic analysis, the patient may still enroll on the trial
