This is an interventional treatment trial for Leukemia focused on measuring adults, Philadelphia chromosome precursor ALL,, T-cell ALL, untreated ALL Read More

Inclusion Criteria:

• Patients must be newly diagnosed (untreated) with Acute Lymphoblastic Leukemia based on a bone marrow examination unless there is a contraindication to having the test performed. This includes precursor-B ALL, precursor-T ALL, and Philadelphia chromosome positive ALL. For reference, see criteria by Center for International Blood and Marrow Transplant Research (CIBMTR).> 20% blasts on a bone marrow aspirate OR If a bone marrow aspirate is not obtained, the diagnosis of acute leukemia can be established by a pathologic diagnosis of acute leukemia on a bone marrow biopsy OR A complete blood count documenting the presence of at least 10,000 white blood cells (WBC)/μl and at least 20% circulating blasts
• Adults, 18 to 60 years of age.
• Women of child bearing potential (WOCBP) must be willing to use adequate contraception to avoid pregnancy for the duration of study participation.
• Eastern Cooperative Oncology Group (ECOG) performance status < 2
• Adequate renal function defined as: Serum creatinine ≤ 2.0 x upper limit normal (ULN) for institution
• Adequate hepatic function defined as:Total bilirubin ≤ 2.0 x ULN for institution Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.0 x ULN for institution
• Patient must have the ability to understand and the willingness to sign a written informed consent document. The patient and/or the patient's legally authorized guardian must acknowledge consent for treatment as a human subject on this study.

Exclusion Criteria:

• Mature B (Burkitt's) ALL will be excluded.
• An active malignancy other than ALL (with the exception of basal and/or squamous cell skin cancers and curatively treated carcinoma of the cervix) within 5 past years of study entry.
• Documented central nervous system (CNS) involvement with leukemia will be excluded. A diagnostic lumbar puncture will not be part of screening procedures.
• Severe pulmonary, renal, or hepatic disease not related to the patient's ALL will be excluded.
• Cardiac dysfunction as defined by:Myocardial infarction within the last 6 months of study entry, or Reduced left ventricular function with an ejection fraction ≤50% as measured by Multigated Acquisition (MUGA) scan or echocardiogram at study entry, Unstable angina, Unstable cardiac arrhythmias, New York Heart Association (NYHA) Class III or IV heart failure, Electrocardiographic evidence of acute ischemia or active conduction system abnormalities
• Known or suspected human immunodeficiency virus (HIV)-positive patients are excluded from the study because of possible risk of lethal infection when treated with marrow suppressive therapy.
• Any concurrent severe and/or uncontrolled medical condition (e.g. uncontrolled diabetes, infection, hypertension, etc.) or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of treatment according to this protocol.
• Patients who have had chemotherapy or radiotherapy for ALL prior to entering the study will be excluded. Hydroxyurea and one dose of intravenous vincristine are allowed prior to registration for patient convenience. Prior steroid therapy is allowable, ≤5 days prior to the start of the regimen.
• Patients may not have received any other investigational agents within the last 30 days.
• WOCBP who are unwilling or unable to use an acceptable method of contraception for the entire study period. Pregnant or lactating women are excluded from this study because of possible risk to the fetus or infant. Women with a positive serum pregnancy test on enrollment or prior to study drug administration will be excluded.
• Men whose sexual partners are WOCBP, who are unwilling or unable to use an acceptable contraceptive method to avoid pregnancy of his partner for the entire study period.
