Dasatinib is an orally bioavailable synthetic small molecule-inhibitor of SRC-family protein-tyrosine kinases. Dasatinib binds to and inhibits the growth-promoting activities of these kinases. Apparently because of its less stringent binding affinity for the BCR-ABL kinase, dasatinib has been shown to overcome the resistance to imatinib of chronic myeloid leukemia (CML) cells harboring BCR-ABL kinase domain point mutations. SRC-family protein-tyrosine kinases interact with variety of cell-surface receptors and participate in intracellular signal transduction pathways; tumorigenic forms can occur through altered regulation or expression of the endogenous protein and by way of virally-encoded kinase genes.
A late-breaking abstract being presented today during the 58th American Society of Hematology Annual Meeting and Exposition in San Diego identifies inherited genetic mutations in the gene IKZF1 that confer a higher likelihood of developing pediatric acute lymphocytic leukemia (ALL).
Research demonstrates the continuing role of allogeneic stem cell transplantation as a salvage option for patients with chronic myeloid leukaemia who progress to accelerated phase or blast crisis after tyrosine kinase inhibitor failure.
Patients with high-risk chronic myeloid leukaemia who undergo allogeneic haematopoietic stem cell transplantation may benefit from continuing with tyrosine kinase inhibitor therapy, US clinicians believe.
Final DASISION study findings confirm dasatinib to be an effective, long-term treatment for patients with a new diagnosis of chronic phase-chronic myeloid leukaemia.
The first-line treatment and monitoring of patients with chronic phase-chronic myeloid leukaemia is in accordance with the European LeukaemiaNet recommendations, finds a real-world clinical practice study.
Treatment-free remission may be feasible in many patients with chronic myeloid leukaemia, say researchers who set out clinical and logistical requirements for discontinuing tyrosine kinase inhibitor therapy.
Calculating halving time of the BCR-ABL transcript after 3 months may help determine prognosis in chronic myeloid leukaemia patients undergoing first-line tyrosine kinase inhibitor therapy, say researchers.
The increased risk of vascular events observed among elderly patients with chronic myeloid leukaemia, compared with patients without cancer, may not be driven by tyrosine kinase inhibitor therapy, US researchers suggest.
A meta-analysis highlights the significantly increased risk of vascular occlusive events in patients with chronic myeloid leukaemia using some new-generation BCR-ABL tyrosine kinase inhibitors compared with use of imatinib.
Lung cancer is one of the most prevalent types of cancer, with more than 20,000 new cases diagnosed each year in Spain. Lung adenocarcinomas carrying oncogenic KRAS, the engine driving these tumours in 30% of cases, constitute the most aggressive sub-type because, unlike other types of lung cancer, there are no targeted therapies beyond the standard cisplatin-based treatment.
A case study suggests that the third-generation tyrosine kinase inhibitor bosutinib may be considered as induction therapy for blast phase chronic myeloid leukaemia in older patients.
A review of BCR–ABL1 tyrosine kinase inhibitors highlights the need to consider cardiovascular adverse event risk profiles when prescribing for patients with chronic myeloid leukaemia.
The type of BCR–ABL transcript could have an impact on tyrosine kinase inhibitor choice in patients with chronic myeloid leukaemia , according to research published in Blood.
A drug commonly used to treat leukaemia is showing potential as a treatment that could slow the progression of the muscle-wasting condition, Duchenne muscular dystrophy.
An international team of scientists, headed by researchers at UC San Diego School of Medicine and UC San Diego Moores Cancer Center, report that decreases in a specific group of proteins trigger changes in the cancer microenvironment that accelerate growth and development of therapy-resistant cancer stem cells (CSCs).
Comorbid conditions that could affect the choice of tyrosine kinase inhibitor are common in patients with chronic myeloid leukaemia, finds an analysis of a US claims database.
The risk of major arterial adverse events in chronic myeloid leukaemia patients may significantly differ between tyrosine kinase inhibitors, suggests a meta-analysis published in Leukemia & Lymphoma.
The risk and impact of cardiovascular adverse events in long-term users of tyrosine kinase inhibitors for chronic myeloid leukaemia is highlighted in a review published in the Journal of Clinical Oncology.
Avillion LLP, a co-developer of late-stage pharmaceutical assets, announces the completion of enrolment in a global Phase III clinical trial called "BFORE," which is designed to assess the effectiveness and safety of BOSULIF (bosutinib) as a first-line treatment for patients with chronic phase Philadelphia chromosome positive (Ph+) chronic myelogenous leukemia (CML).
Researchers have discovered how a common mutation in a high-risk leukemia subtype drives the cancer's aggressiveness and have identified drugs that may work with existing precision medicines to improve survival. St. Jude Children's Research Hospital scientists led the study, which was published online today in the journal Cancer Cell.
