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 review of the European LeukemiaNet guidelines on the care of patients with chronic myeloid leukaemia highlights the need for research into the timing and use of second-line and third-line tyrosine kinase inhibitors.
A Spanish study suggests that bosutinib can help improve or maintain response in patients with chronic myeloid leukaemia after treatment failure of three previous tyrosine kinase inhibitors.
A research team from The Scripps Research Institute, Mayo Clinic and other institutions has identified a new class of drugs that in animal models dramatically slows the aging process—alleviating symptoms of frailty, improving cardiac function and extending a healthy lifespan.
Phase I/II clinical trial data support the use of bosutinib as second- or third-line tyrosine kinase inhibitor therapy in Japanese patients with Philadelphia chromosome-positive chronic myeloid leukaemia.
Timing may be decisive when it comes to overcoming cancer's ability to evade treatment. By hitting breast cancer cells with a targeted therapeutic immediately after chemotherapy, researchers from Brigham and Women's Hospital (BWH) were able to target cancer cells during a transitional stage when they were most vulnerable, killing cells and shrinking tumors in the lab and in pre-clinical models.
PF-114, a selective tyrosine kinase inhibitor, is active against native and mutated forms of the BCR–ABL oncogene in Philadelphia chromosome-positive leukaemias, according to preclinical cellular and in vivo results published in Leukemia.
Patients with chronic myelogenous leukaemia resistant or intolerant to at least one second-generation tyrosine kinase inhibitor have a higher probability of achieving a response to the third-generation TKI ponatinib than to a further second-generation TKI, research indicates.
The uncontrolled growth of cancer cells arises from their ability to hijack the cell’s normal growth program and checkpoints. Usually after therapy, a second cancer-signaling pathway will open after the primary one shuts down — creating an ingenious escape route for the cancer cell to survive. The answer, say Case Western Reserve researchers, is to anticipate and block that back-up track by prescribing two drugs from the start.
ARIAD Pharmaceuticals, Inc. today announced that the Committee for Medicinal Products for Human Use of the European Medicines Agency has adopted its final opinion on Iclusig (ponatinib) following the recommendations made by the Pharmacovigilance Risk Assessment Committee earlier this month.
A leukemia drug called dasatinib shows promise for treating skin, breast and several other cancers, according to researchers at Loyola University Chicago Stritch School of Medicine.
Avillion LLP, a co-developer of late-stage pharmaceutical assets, announces that the first patients have been dosed in the United States in a global Phase 3 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). The first patient was dosed on July 22, 2014.
Researchers have identified additional resistance mechanisms that could be targeted to improve the efficacy of irreversible epidermal growth factor receptor-tyrosine kinase inhibitors in patients with non-small-cell lung cancer harbouring both EGFR and T790M mutations.
An examination of the genetic landscape of head and neck cancers indicates that while metastatic and primary tumor cells share similar mutations, recurrent disease is associated with gene alterations that could be exquisitely sensitive to an existing cancer drug.
Teva Pharmaceutical Industries Ltd. today announced that the U.S. Food and Drug Administration has granted full approval of SYNRIBO (omacetaxine mepesuccinate) for injection. This oncology portfolio product received an accelerated approval in October, 2012 with additional clinical trial data required to fulfill post marketing requirements set forth by the FDA.
BerGenBio AS, an oncology biopharmaceutical company, announces that preclinical data demonstrating that BGB324 has potential application as a novel treatment for Chronic Myeloid Leukemia, was presented in a poster at the Annual Meeting of the American Society of Hematology, which took place on December 7-10, 2013.
Adding the drug dasatinib to a standard antihormone therapy, letrozole, doubled the time before disease progressed for women with hormone receptor-positive, HER2-negative metastatic breast cancer, according to results of a phase II clinical trial presented here at the 2013 San Antonio Breast Cancer Symposium, held Dec. 10-14.
New evidence suggests that using advanced genetics technologies to monitor for remaining cancer cells after treatment may soon become an effective tool to inform treatment decisions and ultimately predict patient outcomes for patients with a particularly aggressive form of acute lymphocytic leukemia (ALL).
ARIAD Pharmaceuticals, Inc. today announced that the European Commission has granted a marketing authorization for Iclusig (ponatinib) as an orphan medicinal product for two indications.
UK and Australian scientists have been able to show ways in which we can markedly improve drug targeting of solid tumours, using tiny 'biosensors' along with new advanced imaging techniques.
Researchers at Moffitt Cancer Center have determined that chronic myeloid leukemia patients who are treated with a class of oral chemotherapy drugs known as a tyrosine kinase inhibitors have significant side effects and quality-of-life issues that need to be addressed. Some of these issues include depression, fatigue, nausea and change of appearance.
