Imatinib Mesylate and Combination Chemotherapy in Treating Patients With Newly Diagnosed Philadelphia Chromosome Positive Acute Lymphoblastic Leukemia
Study Phase: Phase 3
Recruitment Status: Recruiting
Start Date: July 28, 2017
End Date: June 30, 2028
Inclusion Criteria:
- Diagnostic samples will be collected and analyzed according to the procedures of the National front-line protocol
- Patients should be enrolled on National ALL protocol prior to enrollment on EsPhALL2017/COGAALL1631. Regardless of initial front-line protocol baseline diagnostic samples must be available to develop an MRD probe
- BCR-ABL1 fusion (Ph+): newly diagnosed ALL (B-ALL or T-ALL) or mixed phenotypic acute leukemia (MPAL meeting 2016 World Health Organization [WHO] definition) with definitive evidence of BCR-ABL1 fusion by karyotype, fluorescence in situ hybridization (FISH) and/or reverse transcriptase (RT)-PCR
- ABL-class fusion: newly diagnosed B-ALL with definitive evidence of ABL-class fusions identified according to National/Center procedures of each participating country. ABL-class fusions are defined as those involving the following genes: ABL1, ABL2, CSF1R, PDGFRB, PDGFRA, LYN. Methods of detection include fluorescence in-situ hybridization (FISH, e.g. using break-apart or colocalization signals probes), multiplex or singleplex reverse-transcription polymerase chain reaction (RT-PCR), whole transcriptome or panel-based ribonucleic acid (RNA)-sequencing
- Regardless of initial front-line protocol, laboratory reports detailing evidence of BCR-ABL1 or ABL-class fusion must be available for the National Trial Unit
- Ph+ ALL patients must have previously started induction therapy, which includes vincristine, a corticosteroid, usually PEG-L-asparaginase, with or without anthracycline, and/or other standard cytotoxic chemotherapy
- Ph+ ALL patients have not received more than 14 days of multiagent induction therapy beginning with the first dose of vincristine
- Ph+ ALL patients may have started imatinib prior to study entry but have not received more than 14 days of imatinib
- ABL-class fusion patients must have previously completed the 4 or 5 weeks of multiagent Induction chemotherapy
- ABL-class fusion patients may have started imatinib during Induction IA, at the same time of or after the first vincristine dose
- Patients must have a performance status corresponding to Eastern Cooperative Oncology Group (ECOG) scores of 0, 1, or 2
- Direct bilirubin =< 2.0 mg/dL
- Shortening fraction of >= 27% by echocardiogram
- Ejection fraction of >= 50% by radionuclide angiogram or echocardiogram
- Corrected QT interval, QTc < 480 msec
- Note: Repeat echocardiogram and electrocardiogram are not required if they were performed at or after initial ALL diagnosis, before study enrollment
- Creatinine clearance or radioisotope glomerular filtration rate (GFR) >= 70 mL/min/1.73 m^2 or serum creatinine within normal limits based on age/gender, as follows:
- 1 to < 2 years: maximum serum creatinine 0.6 mg/dL (both male and female)
- 2 to < 6 years: maximum serum creatinine 0.8 mg/dL (both male and female)
- 6 to < 10 years: maximum serum creatinine 1 mg/dL (both male and female)
- 10 to < 13 years: maximum serum creatinine 1.2 mg/dL (both male and female)
- 13 to < 16 years: maximum serum creatinine 1.5 mg/dL (male), 1.4 mg/dL (female)
- >= 16 years: maximum serum creatinine 1.7 mg/dL (male), 1.4 mg/dL (female)
Exclusion Criteria:
- Known history of chronic myelogenous leukemia (CML)
- ALL developing after a previous cancer treated with cytotoxic chemotherapy
- Active, uncontrolled infection, or active systemic illness that requires ongoing vasopressor support or mechanical ventilation
- Down syndrome
- Pregnancy and breast feeding
- 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 treatment according to protocol
- Patients with congenital long QT syndrome, history of ventricular arrhythmias or heart block
- Prior treatment with dasatinib, or any TKI inhibitor other than imatinib
- All patients and/or their parents or legal guardians must sign a written informed consent
