Purpose Safe, effective treatments are needed for pediatric patients with chronic myeloid leukemia in chronic phase (CML-CP). Dasatinib is approved for treatment of adults and children with CML-CP. A phase I study determined suitable dosing for children with Philadelphia chromosome-positive (Ph+) leukemias. Methods CA180-226/NCT00777036 is a phase II, open-label, nonrandomized prospective trial of patients < 18 years of age receiving dasatinib. There are three cohorts: (1) imatinib-resistant/intolerant CML-CP, (2) imatinib-resistant/intolerant CML in accelerated/blast phase or Ph+ acute lymphoblastic leukemia (n = 17), and (3) newly diagnosed CML-CP treated with tablets or powder for oral suspension...

High-risk subtypes of B-cell acute lymphoblastic leukemia (B-ALL) include Philadelphia chromosome-positive (Ph+) B-ALL driven by the BCR-ABL1 oncogene and a more recently identified subtype known as BCR-ABL -like or Ph-like B-ALL. A hallmark of both Ph+ and Ph-like B-ALL is constitutive activation of tyrosine kinase signaling that is potentially targetable with tyrosine kinase inhibitors (TKIs). B-ALL cells also receive extracellular signals from the microenvironment that can maintain proliferation and survival following treatment with TKIs...

E14a3 breakpoint cluster region (BCR)/ABL proto-oncogene 1, non-receptor tyrosine kinase (ABL) fusion transcript is rare in Philadelphia chromosome positive disease, particularly in acute lymphoblastic leukemia (ALL). Recently an e14a3 fusion transcript was detected by multiple laboratory examinations, and the patient was suffering from ALL. Except for the BCR/ABL fusion gene, in the present study the patient additionally had an IKAROS family zinc finger 1 deletion which, has been confirmed as a significant adverse prognosis factor...

Relapse remains one of the major obstacles in Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph + ALL) even after allogeneic hematopoietic stem cell transplantation. The persistence of leukemia-propagating cells (LPCs) may lead to the recurrence of Ph + ALL. Using a xenograft assay, LPCs enrichment in the CD34 + CD38 - CD58 - fraction in Ph + ALL was recently identified. A further cohort study indicated that the LPCs phenotype at diagnosis was an independent risk factor for relapse of Ph + ALL...

The introduction of BCR-ABL-tyrosine kinase inhibitors (TKI) for treatment of hematologic malignancies has made a significant impact on patient outcome. Contingent upon their targeted and off-target activity, therapy-associated infectious complications may occur. We present a case of cytomegalovirus pneumonitis and a case of adenovirus hemorrhagic cystitis in two patients with Philadelphia chromosome-positive acute lymphoblastic leukemia on BCR-ABL TKI treatment and review the literature to summarize the infectious complications based on clinical data...

INTRODUCTION: The prognosis of Philadelphia chromosome positive acute lymphoblastic leukemia (Ph + ALL) has been dramatically improved since the introduction of tyrosine kinase inhibitors (TKIs). Although allogeneic hematopoietic cell transplantation (allo-HCT) is a major treatment option, the role of autologous peripheral blood stem cell transplantation (auto-PBSCT) has been reconsidered, especially in patients who achieved early molecular remission. METHODS AND ANALYSIS: This is a multicenter exploratory study for Ph + ALL patients aged between 55 and 70 years who achieved complete molecular remission within 3 cycles of chemotherapy...

Approximately 30-50% of adults with acute lymphoblastic leukemia (ALL) in hematologic complete remission following multiagent therapy exhibit minimal residual disease (MRD) by reverse transcriptase-polymerase chain reaction or flow cytometry. MRD is the strongest predictor of relapse in ALL. In this open-label, single-arm study, adults with B-cell precursor ALL in hematologic complete remission with MRD (≥10-3 ) received blinatumomab 15 µg/m2 /day by continuous intravenous infusion for up to four cycles...

HyperCVAD is a commonly-used regimen for adults with newly-diagnosed acute lymphoblastic leukemia (ALL). However, relatively little is known about the application of minimal residual disease (MRD) detection with this treatment. To address this, we studied 142 adults with ALL treated with hyperCVAD over a 10-year period who had MRD assessed by either multi-parameter flow cytometry or (for patients with Philadelphia chromosome positive ALL) reverse transcriptase polymerase chain reaction for the BCR-ABL1 translocation...

Dasatinib is a second generation ABL kinase inhibitor used in the management of chronic myeloid leukemia or Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL). Dasatinib's bioavailability is highly dependent on gastric pH. When proton-pump inhibitors (PPIs) are co-administered with dasatinib, absorption is significantly reduced. Cola intake at the time of drug administration has been demonstrated to lead to relevant increases in the bioavailability for other acid labile drugs during PPI treatment...

Prognosis of childhood acute lymphoblastic leukemia (ALL) has been dramatically improved. However, prognosis of the cases refractory to primary therapy is still poor. Recent phase 2 study on the efficacy of combination chemotherapy with bortezomib (BTZ), a proteasome inhibitor, for refractory childhood ALL demonstrated favorable clinical outcomes. However, septic death was observed in over 10% of patients, indicating the necessity of biomarkers that could predict BTZ sensitivity. We investigated in vitro BTZ sensitivity in a large panel of ALL cell lines that acted as a model system for refractory ALL, and found that Philadelphia chromosome-positive (Ph+) ALL, IKZF1 deletion, and biallelic loss of CDKN2A were associated with favorable response...

Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) is currently treated with BCR-ABL1 tyrosine kinase inhibitors (TKI) in combination with chemotherapy. However, most patients develop resistance to TKI through BCR-ABL1-dependent and -independent mechanisms. Newly developed TKI can target Ph+ ALL cells with BCR-ABL1-dependent resistance; however, overcoming BCR-ABL1-independent mechanisms of resistance remains challenging because transcription factors, which are difficult to inhibit, are often involved...

Treatment of Philadelphia chromosome positive acute lymphoblastic leukemia exemplifies how the addition of potent targeted agents, directed at the molecular aberrations responsible for leukemic transformation, can overcome resistance mechanisms to traditional regimens and lead to improved outcomes. The introduction of BCR-ABL1 targeted tyrosine kinase inhibitors (TKIs) has significantly improved the outcomes not only by allowing more patients to undergo allogeneic hematopoietic cell transplantation (alloHCT) but also by decreasing our reliance on this potentially toxic strategy, particularly in the less fit population...

We retrospectively analyzed the samples collected from 66 patients with Ph+ ALL enrolled on ChiCTR-TNRC-09000309 clinical trial. CR rate was 95.5%, and estimated 2-year OS and DFS were 51.7 ± 11.7% and 26.9 ± 11.6%, 3-year OS and DFS were 31.6 ± 12.0% and 23.4 ± 11.6%. By combining IKZF1 deletion and early molecular responses, we redefined the patients as low, intermediate, and high risk 3 groups separately. Patients with double negative in IKZF1 and early molecular response experienced significant superior survival, while patients with double positive would have the worst outcome, and patients who were one or the other with IKZF1 deletion or MRD status had intermediate outcome...

A 54-year-old woman with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL) underwent hematopoietic stem cell transplantation from an HLA-matched sibling. Subsequently, she suffered from chronic graft versus host disease (GvHD) and received medical treatment. Fever developed on day 697 and resulted in a shock state at 10 h after the visit. Achromobacter xylosoxidans was detected in the initial blood culture on day 699. General conditions exacerbated even after the start of meropenem hydrate (MEPM, Meropen® ) administration, with Corynebacterium striatum detected as an additional species in the initial blood culture on day 701...

Ponatinib, a novel tyrosine kinase inhibitor marketed in 2016, is a key drug used for treating chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia. This study aimed to develop a simple method for determining plasma ponatinib concentration. The analysis required extraction of a 400-µL sample of plasma and precipitation of proteins using an Oasis HLB cartridge. Ponatinib and bosutinib, which is used as an internal standard, were separated by HPLC using a mobile phase of acetonitrile : 0...
