Clinical Trials

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
• Mature B ALL (Burkitt's-like leukemia) is excluded from enrollment in this trial; pre-study bone marrow biopsy and aspirate must be completed ≤ 1 week prior to registration
• 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
• Patient must not have a concurrent active malignancy for which they are receiving treatment
• Serum direct bilirubin < 2 mg/dl or serum total bilirubin ≤ 3; NOTE: the above stipulation for normal hepatic function does not apply if liver dysfunction is due to leukemia infiltration
• Serum creatinine < 2 mg/dl; NOTE: the above stipulation for normal hepatic function does not apply if liver dysfunction is due to leukemia infiltration
• Patient should be human leukocyte antigen (HLA) typed (A, B, C, DR and DQ) during induction therapy phase or a written explanation for not undergoing HLA typing on the flow sheet

  • No history of acquired immune deficiency syndrome (AIDS)-related complications other than a history of low CD4+ T-cell count (< 200/mm^3) prior to initiation of combination antiretroviral therapy; on study CD4+ T-cell count may not be informative due to leukemia and should not be used as an exclusion criterion if low
  • Patient must be healthy on the basis of HIV disease with high likelihood of near normal life span were it not for the leukemia
  • Patient must have serum HIV viral load of < 200 copies/mm^3
  • Patient must be on combination antiretroviral therapy with minimal pharmacokinetic interactions with study therapy and minimal overlapping clinical toxicity with protocol therapy

• Patient must not have an antecedent hematologic disorder
• Patient must have no history of recent myocardial infarction (within three months), uncontrolled congestive heart failure, or uncontrolled cardiac arrhythmia
• Patient must not have a history or presence of clinically relevant central nervous system (CNS) pathology such as epilepsy, seizure, paresis, aphasia, stroke, severe brain injuries, dementia; Parkinson's disease, cerebellar disease, organic brain syndrome, psychosis, or other significant CNS abnormalities
• Patient must have a normal cardiac ejection fraction by pretreatment multigated acquisition scan (MUGA) or echocardiogram within 4 weeks prior to registration (resting ejection fraction ≥ 40% or ≥5% increase with exercise), shortening fraction by echocardiogram ≥24%, or to within the normal range of values for the institution
• Patient must not have an active uncontrolled infection
• Women must not be pregnant or breast-feeding and must not become pregnant or breastfeed during protocol therapy and for at least 3 months after protocol therapy; woman of childbearing potential must abstain from sexual activity or be willing to use 2 highly effective forms of contraception throughout protocol therapy and for at least an additional 3 months after the last dose of protocol-specified therapy; all females of childbearing potential must have a blood test or urine study within 2 weeks prior to registration to rule out pregnancy; a female of childbearing potential is any woman, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria: has not undergone a hysterectomy or bilateral oophorectomy; or has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)
