Effectiveness of Gefitinib against Non-Small-Cell Lung Cancer with the Uncommon EGFR Mutations G719X and L861Q.

In non-small-cell lung cancer, an exon 19 deletion and an L858R point mutation in the epidermal growth factor receptor (EGFR) are predictors of a response to EGFR-tyrosine kinase inhibitors. However, it is uncertain whether other uncommon EGFR mutations are associated with sensitivity to EGFR-tyrosine kinase inhibitors.

Sorafenib: targeting multiple tyrosine kinases in cancer.

Sorafenib (BAY 43-9006, Nexavar(®)) is an oral multiple tyrosine kinase inhibitor. Main targets are receptor tyrosine kinase pathways frequently deregulated in cancer such as the Raf-Ras pathway, vascular endothelial growth factor (VEGF) pathway, and FMS-like tyrosine kinase 3 (FLT3). Sorafenib was approved by the FDA in fast track for advanced renal cell cancer and hepatocellular cancer and shows good clinical activity in thyroid cancer. Multiple clinical trials are undertaken to further investigate the r...

Different efficacy of EGFR tyrosine kinase inhibitors and prognosis in patients with subtypes of EGFR-mutated advanced non-small cell lung cancer: a meta-analysis.

Nearly 85 % of lung-cancer-specific epidermal growth factor receptor (EGFR) sensitive mutations comprise a substitution at position 858 (21L858R) and deletion mutants in exon 19 (19del). The aim of this study was to assess the role of EGFR mutation subtypes in predicting the efficacy of EGFR tyrosine kinase inhibitors (EGFR TKIs) and the prognosis of patients with advanced non-small cell lung cancer (NSCLC).

Omacetaxine mepesuccinate in the treatment of intractable chronic myeloid leukemia.

In a significant proportion of patients with chronic myeloid leukemia, resistance to BCR-ABL tyrosine kinase inhibitors develops due to acquisition of BCR-ABL kinase domain mutations and insensitivity of leukemia stem cells to tyrosine kinase inhibitors. Omacetaxine mepesuccinate (formerly called homoharringtonine) is a natural alkaloid that inhibits protein synthesis and induces cell death. Omacetaxine mepesuccinate has been recently approved by the US Food and Drug Administration to treat patients with ch...

Meta-Analysis of EGFR Tyrosine Kinase Inhibitors Compared with Chemotherapy as Second-Line Treatment in Pretreated Advanced Non-Small Cell Lung Cancer.

Since efficacy and safety of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) versus chemotherapy in the treatment of patients with pretreated advanced non-small cell lung cancer (NSCLC) remain controversial, we performed a meta-analysis to compare them.

Nomogram Predicting Clinical Outcomes in Non-Small Cell Lung Cancer Patients Treated with Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors.

The aim of this study was to develop a pragmatic nomogram for prediction of progression free survival (PFS) for the epidermal growth factor (EGFR) tyrosine kinase inhibitor (TKI) in EGFR mutant non-small cell lung cancer (NSCLC).

Nilotinib.

Targeted therapy of Philadelphia chromosome-positive chronic myeloid leukemia (CML) using the tyrosine kinase inhibitor imatinib mesylate has been one of the most striking achievements in modern cancer medicine. However, while imatinib can establish long-term remission in many cases, resistance to or intolerance of imatinib is eventually experienced by a substantial number of patients. Subsequent advances have led to the development of novel tyrosine kinase inhibitors (TKIs). One such inhibitor, nilotinib,...

Comparison of pemetrexed and docetaxel as salvage chemotherapy for the treatment for nonsmall-cell lung cancer after the failure of epidermal growth factor receptor-tyrosine kinase inhibitors.

To compare the therapeutic effects and adverse reactions of pemetrexed and docetaxel as salvage chemotherapy in patients with nonsmall-cell lung cancer (NSCLC) after the failure of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI).

Different treatment orders achieved similar clinical results: a retrospective study for retreatment of epidermal growth factor receptor tyrosine kinase inhibitors in 120 patients with non-small-cell lung cancer.

It was reported the retreatment of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) may bring benefit to non-small-cell lung cancer (NSCLC) patients who benefited previously. Nevertheless, the treatment order in most of the prior literature was gefitinib (G) to erlotinib (E), and little was known about whether other treatment order may also bring benefit to the patients.

The tyrosine kinase inhibitor nilotinib has antineoplastic activity in prostate cancer cells but up-regulates the ERK survival signal-Implications for targeted therapies.

Novel therapeutic options beyond hormone ablation and chemotherapy are urgently needed for patients with advanced prostate cancer. Tyrosine kinase inhibitors (TKIs) are an attractive option as advanced prostate cancers show a highly altered phosphotyrosine proteome. However, despite favorable initial clinical results, the combination of the TKI dasatinib with docetaxel did not result in improved patient survival for reasons that are not known in detail.

Small-molecule EGFR tyrosine kinase inhibitors for the treatment of cancer.

Introduction: EGFR has been implicated in various malignancies such as NSCLC, breast, head and neck, and pancreatic cancer. Numerous drugs have been developed in order to target the tyrosine domain of EGFR as an approach in cancer treatment. Areas covered: This article focuses on the different generations of EGFR tyrosine kinase inhibitors (TKIs). This spans from the emergence of the first-generation EGFR-TKIs to overcoming drug resistance using second-generation EGFR-TKIs and to reducing adverse effect (AE...

Primary and Secondary Resistance to Tyrosine Kinase Inhibitors in Lung Cancer.

Background: Tyrosine kinase inhibitors (TKI) have emerged as important therapeutic agents for the treatment of several types of cancer including lung cancer. Recent research attempts show that only a small population of cancer patients responds to TKI and furthermore, these patients eventually develop resistance. Studies support the classification of resistance in primary and secondary resistance. Materials and Methods: In the present study the differentiation between primary and secondary resistance to TKI...

Translational evidence on the role of Src kinase and activated Src kinase in invasive breast cancer.

Src kinase is a member of a non-receptor tyrosine kinase family. It has been implicated as a regulator of cell proliferation and survival and plays a complex role in cell adhesion and motility. In vitro evidence for a role for Src in breast cancer is compelling. However, only a few translational clinical studies have been undertaken in this field. This review summarises translational evidence on expression and activation of Src kinase in breast cancer patient cohorts exploring clinical significance and the...

Development of anaplastic lymphoma kinase (ALK) inhibitors and molecular diagnosis in ALK rearrangement-positive lung cancer.

The fusion of echinoderm microtubule-associated protein-like 4 with anaplastic lymphoma kinase (ALK) was identified as a transforming gene for lung cancer in 2007. This genetic rearrangement accounts for 2%-5% of non-small-cell lung cancer (NSCLC) cases, occurring predominantly in younger individuals with adenocarcinoma who are never- or light smokers. A small-molecule tyrosine-kinase inhibitor of ALK, crizotinib, was rapidly approved by the US Food and Drug Administration on the basis of its pronounced cli...

Bruton's tyrosine kinase inhibitors: lessons learned from bench-to-bedside (first) studies.

Targeted inhibitors of B-cell receptor signaling have emerged as the most promising therapeutic options against non-Hodgkin's lymphoma. The inhibitor agents that target Bruton's tyrosine kinase (BTK) have elicited particularly high enthusiasm given the unprecedented positive responses observed in Phase I trials. The sheer amount of clinical data published since last year now requires reinterpretation in light of recently published findings on BTK.

Rapid Evaluation of Tyrosine Kinase Activity of Membrane-Integrated Human Epidermal Growth Factor Receptor Using the Yeast Gγ Recruitment System.

Epidermal growth factor receptor (EGFR) is a member of the receptor tyrosine kinase family and plays key roles in the regulation of fundamental cellular processes, including cell proliferation, migration, differentiation, and survival. Deregulation of EGFR tyrosine kinase activity is involved in the development and progression of human cancers. In the present study, we attempted to develop a method to evaluate the tyrosine kinase activity of human EGFR using the yeast Gγ recruitment system. Autophosphoryla...

Imatinib: a breakthrough of targeted therapy in cancer.

Deregulated protein tyrosine kinase activity is central to the pathogenesis of human cancers. Targeted therapy in the form of selective tyrosine kinase inhibitors (TKIs) has transformed the approach to management of various cancers and represents a therapeutic breakthrough. Imatinib was one of the first cancer therapies to show the potential for such targeted action. Imatinib, an oral targeted therapy, inhibits tyrosine kinases specifically BCR-ABL, c-KIT, and PDGFRA. Apart from its remarkable success in CM...

Reduced annexin A6 expression promotes the degradation of activated epidermal growth factor receptor and sensitizes invasive breast cancer cells to EGFR-targeted tyrosine kinase inhibitors.

The expression of annexin A6 (AnxA6) in AnxA6-deficient non-invasive tumor cells has been shown to terminate epidermal growth factor receptor (EGFR) activation and downstream signaling. However, as a scaffolding protein, AnxA6 may stabilize activated cell-surface receptors to promote cellular processes such as tumor cell motility and invasiveness. In this study, we investigated the contribution of AnxA6 in the activity of EGFR in invasive breast cancer cells and examined whether the expression status of Anx...

Ability of the Met Kinase Inhibitor Crizotinib and New Generation EGFR Inhibitors to Overcome Resistance to EGFR Inhibitors.

Although EGF receptor tyrosine kinase inhibitors (EGFR-TKI) have shown dramatic effects against EGFR mutant lung cancer, patients ultimately develop resistance by multiple mechanisms. We therefore assessed the ability of combined treatment with the Met inhibitor crizotinib and new generation EGFR-TKIs to overcome resistance to first-generation EGFR-TKIs.

Clinical Targeting of Mutated and Wild-type Protein Tyrosine Kinases in Cancer.

Clinical therapies for cancer have evolved from toxic, non-targeted agents to manageable, highly targeted therapies. Protein tyrosine kinases are a family of signaling molecules implicated in nearly every cancer type and are the foundation for the development of modern targeted agents. Recent genomic analyses have identified activating mutations, translocations, and amplifications of tyrosine kinases. Selective targeting of these genetically altered tyrosine kinases has resulted in significant clinical adva...

The Bim deletion polymorphism clinical profile and its relation with tyrosine kinase inhibitor resistance in Chinese patients with non-small cell lung cancer.

Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are widely used for the treatment of patients with advanced non-small cell lung cancer (NSCLC) who have EGFR mutations. Recent studies have indicated that some patients with positive mutations were refractory to EGFR TKIs if they harbored a B-cell chronic lymphocytic leukemia/lymphoma (Bcl-2)-like 11 (Bim) deletion polymorphism. The objective of the current work was to retrospectively study the Bim deletion polymorphism in Chinese pat...

Drug resistance and BCR-ABL kinase domain mutations in philadelphia chromosome-positive acute lymphoblastic leukemia from the imatinib to the second-generation tyrosine kinase inhibitor era: The main changes are in the type of mutations, but not in the frequency of mutation involvement.

Patients with Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) frequently relapse on imatinib with acquisition of BCR-ABL kinase domain (KD) mutations. To analyze the changes that second-generation tyrosine kinase inhibitors (TKIs) have brought in mutation frequency and type, a database review was undertaken of the results of all the BCR-ABL KD mutation analyses performed in the authors' laboratory from January 2004 to January 2013.

Inhibition of OATP1B1 by tyrosine kinase inhibitors: in vitro-in vivo correlations.

Background:Several tyrosine kinase inhibitors (TKIs) can decrease docetaxel clearance in patients by an unknown mechanism. We hypothesised that these interactions are mediated by the hepatic uptake transporter OATP1B1.Methods:The influence of 16 approved TKIs on transport was studied in vitro using HEK293 cells expressing OATP1B1 or its mouse equivalent Oatp1b2. Pharmacokinetic studies were performed with Oatp1b2-knockout and OATP1B1-transgenic mice.Results:All docetaxel-interacting TKIs, including sorafeni...

Aurora kinase inhibition induces PUMA via NF-kB to kill colon cancer cells.

Aurora kinases play a key role in mitosis and are frequently overexpressed in a variety of tumor cells. Inhibition of aurora kinases results in mitotic arrest and death of cancer cells, and has been explored as an anticancer strategy. However, how aurora inhibition kills cancer cells is poorly understood. In this study, we found that inhibition of aurora kinases by siRNA or small-molecule inhibitors led to induction of PUMA, a BH3-only Bcl-2 family protein, in colorectal cancer cells irrespective of p53 sta...

Erlotinib.

The epidermal growth factor receptor (EGFR) has been implicated in a multiplicity of cancer-related signal transduction pathways such as cellular proliferation, adhesion, migration, neoangiogenesis and apoptosis inhibition, all of them are important features of cancerogenesis and tumour progression. Its tyrosine kinase activity plays a central role in mediating these processes and has been intensely studied to exploit it as a therapeutic target. Inhibitors of this pathway have been developed and assessed in...
