AALL1131: Combination Chemotherapy in Treating Young Patients With Newly Diagnosed High-Risk B Acute Lymphoblastic Leukemia and Ph-Like TKI Sensitive Mutations


  • B Acute Lymphoblastic Leukemia


This randomized phase III trial studies how well combination chemotherapy works in treating young patients with newly diagnosed B acute lymphoblastic leukemia that is likely to come back or spread, and in patients with Philadelphia chromosome (Ph)-like tyrosine kinase inhibitor (TKI) sensitive mutations. 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. Giving more than one drug (combination chemotherapy) and giving the drugs in different doses and in different combinations may kill more cancer cells.

Eligibility Criteria

  • Ages eligible for study: 1 year to 30 years (Child, Adult)
  • Patients must be enrolled on APEC14B1 and consented to Eligibility Screening on the Part A consent form prior to enrollment on AALL1131
  • Patients must meet White Blood Cell Count (WBC) Criteria
  • Patients must have newly diagnosed B lymphoblastic leukemia (2008 World Health Organization [WHO] classification) (also termed B-precursor acute lymphoblastic leukemia); patients with Down syndrome are also eligible
  • Organ function requirements for patients with Ph-like ALL and a predicted TKI-sensitive mutation: patients identified as Ph-like with a TKI-sensitive kinase mutation must have assessment of organ function performed within 3 days of study entry onto the dasatinib arm of AALL1131
  • Creatinine clearance or radioisotope glomerular filtration rate (GFR) > 70mL/min/1.73 m^2 or a serum creatinine based on age/gender
  • Direct bilirubin =< 3 x upper limit of normal (ULN) for age, and
  • Serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) =< 10 x upper limit of normal (ULN) for age
  • Shortening fraction >= 27% by echocardiogram, or ejection fraction >= 50% by gated radionuclide study
  • No evidence of dyspnea at rest, no exercise intolerance, and a pulse oximetry > 94% at sea level if there is clinical indication for determination
