Bovine serum albumin binding study to erlotinib using surface plasmon resonance and molecular docking methods.

Bovine serum albumin (BSA) is the most abundant protein in the blood circulation and it is commonly used for drug delivery in blood. Therefore, we aim to study BSA interaction with erlotinib as an anticancer drug using surface plasmon resonance (SPR) and molecular modeling methods under physiological conditions (pH = 7.4). BSA immobilized on carboxymethyl dextran hydrogel Au chip (CMD) after activation with N-hydroxysuccinimide and N-ethyl-N-(3-diethylaminopropyl) carbodiimide and then the erlotinib bin...

Effects of proton pump inhibitor co-administration on the plasma concentration of erlotinib in patients with non-small cell lung cancer.

Erlotinib is used for treating non-small cell lung cancer (NSCLC). Intestinal absorption of erlotinib is impaired under gastric pH elevation, therefore, co-administration of gastric acid suppressants may provide lower blood concentration of erlotinib. We investigated the effects of erlotinib co-administration with proton pump inhibitors (PPI) and histamine H2 receptor blockers (H2RB) on the plasma concentration of erlotinib and erlotinib-induced adverse reaction in NSCLC patients.


Quantitative determination of erlotinib in human serum using competitive enzyme-linked immunosorbent assay.

A selective and sensitive competitive enzyme-linked immunosorbent assay (ELISA) method was developed and validated for the quantification of erlotinib in 50 µL of samples of human serum. Anti-erlotinib serum was obtained by immunizing mice with an antigen conjugated with bovine serum albumin and 3,4-bis(2-methoxyethoxy)benzoic acid using the -succinimidyl ester method. Enzyme labeling of erlotinib with horseradish peroxidase was similarly performed using 3,4-bis(2-methoxyethoxy)benzoic acid. A simple comp...

A phase I study of the farnesyltransferase inhibitor Tipifarnib in combination with the epidermal growth factor tyrosine kinase inhibitor Erlotinib in patients with advanced solid tumors.

Introduction Based on preclinical cytotoxic synergy between tipifarnib and erlotinib, a phase I study of this combination was conducted in patients with advanced solid tumors to evaluate safety, tolerability, maximum tolerated dose (MTD) and preliminary evidence of efficacy. Methods Patient enrollment followed the traditional "3 + 3" dose escalation scheme, through 4 dose levels, ranging from tipifarnib 200 mg twice daily plus erlotinib 75 mg once daily to tipifarnib 300 mg twice daily plus erlotinib 150...

Distribution of erlotinib in rash and normal skin in cancer patients receiving erlotinib visualized by matrix assisted laser desorption/ionization mass spectrometry imaging.

The development of skin rashes is the most common adverse event observed in cancer patients treated with epidermal growth factor receptor-tyrosine kinase inhibitors such as erlotinib. However, the pharmacological evidence has not been fully revealed.

A receptor tyrosine kinase ROR1 inhibitor (KAN0439834) induced significant apoptosis of pancreatic cells which was enhanced by erlotinib and ibrutinib.

There is a great unmet medical need in pancreatic carcinoma (PC) for novel drugs with other mechanisms of action than existing. PC cells express the onco-fetal RTK ROR1, absent on most normal post-partem cells. ROR1 is involved in proliferation, survival, EMT and metastasis of tumor cells in various malignancies. A small molecule inhibitor (KAN0439834) (530 Da) targeting the TK domain of ROR1 was developed and the activity in ROR1 expressing human PC cell lines (n = 8) evaluated. The effects were compared t...

A Pilot Phase II Study of Erlotinib for the Treatment of Patients with Relapsed/Refractory Acute Myeloid Leukemia.

Erlotinib, an epidermal growth factor receptor (EGFR) inhibitor, may have off-target activity inducing acute myeloid leukemia (AML) differentiation, possibly through SYK inhibition. We investigated erlotinib in a pilot phase II study for efficacy in relapsed/refractory AML patients at a dose of 150 mg once daily in 28-day cycles. Twenty-nine patients were treated for a median of 29 days (range 12-142 days). Seven patients (24%) received > 1 cycle of therapy and 12 (41%) discontinued treatment before day 28 ...

Survival outcomes in patients with non-small-cell lung cancer treated with erlotinib.

Erlotinib is used to treat non-small-cell lung cancer (NSCLC). Erlotinib was subsidized on the Pharmaceutical Benefits Schedule in Australia for the treatment of advanced stage (IIIB or IV) NSCLC (August 2008). In the pivotal trial supporting initial subsidy, erlotinib increased overall survival (OS) by 2 months compared with placebo (adjusted hazard ratio, 0.70; 95% confidence interval: 0.58-0.85). We examined the effectiveness of erlotinib in a 'real-world' setting by measuring survival outcomes in NSCLC ...

Downregulation of GEP100 Improved the Growth Inhibition Effect of Erlotinib Through Modulating Mesenchymal Epithelial Transition Process in Pancreatic Cancer.

The epidermal growth factor receptor is overexpressed in the majority of pancreatic cancer. Epidermal growth factor receptor tyrosine kinase inhibitor erlotinib was approved to treat the patient combining with gemcitabine. However, the sensitivity is low. Here, we try to reveal the regulatory role of guanine nucleotide exchange protein 100 (GEP100) in erlotinib sensitivity.

mTORC2 contributes to the metabolic reprogramming in EGFR tyrosine-kinase inhibitor resistant cells in non-small cell lung cancer.

Non-small cell lung cancer (NSCLC) patients with activating EGFR mutations are often successfully treated with EGFR tyrosine kinase inhibitor (TKI) such as erlotinib; however, treatment resistance inevitably occurs. Given tumor metabolism of glucose and therapeutic response are intimately linked, we explored the metabolic differences between isogenic erlotinib-sensitive and -resistant NSCLC cell lines. We discovered that the growth of erlotinib-resistant cells is more sensitive to glucose deprivation. Seaho...

Feasibility and biological rationale of repurposing sunitinib and erlotinib for dengue treatment.

There is an urgent need for strategies to combat dengue virus (DENV) infection; a major global threat. We reported that the cellular kinases AAK1 and GAK regulate intracellular trafficking of multiple viruses and that sunitinib and erlotinib, approved anticancer drugs with potent activity against these kinases, protect DENV-infected mice from mortality. Nevertheless, further characterization of the therapeutic potential and underlying mechanism of this approach is required prior to clinical evaluation. Here...

Erlotinib-guided self-assembled trifunctional click nanotheranostics for distinguishing druggable mutations and synergistic therapy of NSCLC.

The outcome of molecular targeted therapies is restricted by the ambiguous molecular subtypes of non-small cell lung cancer (NSCLC) which are difficult to be defined with druggable mutations, and the inevitable emergence of drug-resistance. Here we used the Cu-catalyzed click chemistry to synthesize a chitosan-based self-assembled nanotheranostics (CE7Ns) composing of a near-infrared (NIR) fluorescent photosensitizer Cy7 and molecular targeted drug erlotinib. The well-characterized CE7Ns can release erlotin...

Early emergence of de novo EGFR T790 M gatekeeper mutations during erlotinib treatment in PC9 non-small cell lung cancer cells.

The emergence of the T790 M gatekeeper mutation in the Epidermal Growth Factor Receptor (EGFR) gene is an important mechanism that can lead to the acquired resistance to EGFR-targeted tyrosine kinase inhibitors such as erlotinib or gefitinib. These drugs have been used in treating a subset of non-small cell lung cancer (NSCLC) patients harboring EGFR activating mutations. Here we investigated the paths leading to the acquisition of the T790 M mutation by establishing an erlotinib resistant PC9 cell mode...

Response to Erlotinib in a Patient with Compound EGFR L747S and Exon 19 Deletion.

YM155 sensitizes non-small cell lung cancer cells to EGFR-tyrosine kinase inhibitors through the mechanism of autophagy induction.

Resistance to epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs), such as erlotinib and gefitinib, is a major clinical problem in the treatment of patients with non-small cell lung cancer (NSCLC). YM155 is a survivin small molecule inhibitor and has been demonstrated to induce cancer cell apoptosis and autophagy. EGFR-TKIs have been known to induce cancer cell autophagy. In this study, we showed that YM155 markedly enhanced the sensitivity of erlotinib to EGFR-TKI resistant NSCLC cell l...

To investigate the cost-effectiveness of afatinib and erlotinib as second-line therapy for advanced squamous cell carcinoma of the lung.

Targeting autophagy by small molecule inhibitors of vacuolar protein sorting 34 (Vps34) improves the sensitivity of breast cancer cells to Sunitinib.

Resistance to chemotherapy is a challenging problem for treatment of cancer patients and autophagy has been shown to mediate development of resistance. In this study we systematically screened a library of 306 known anti-cancer drugs for their ability to induce autophagy using a cell-based assay. 114 of the drugs were classified as autophagy inducers; for 16 drugs, the cytotoxicity was potentiated by siRNA-mediated knock-down of Atg7 and Vps34. These drugs were further evaluated in breast cancer cell lines ...

A surface enhanced Raman scattering based colloid nanosensor for developing therapeutic drug monitoring.

Competitive reactions, on the surface of plasmonic nanostructures, allow exploiting SERS signals for quantitative Therapeutic Drug Monitoring. As an example, the concentration of Erlotinib, an anti-EGFR small molecule, used for the treatment of non-small cell lung and pancreatic cancer, is determined. The numerous side effects and the variability of patient responses make Erlotinib a good candidate for monitoring. The new SERS based sensor can estimate Erlotinib down to nanomolar concentration and is based ...

Chloroquine in combination with aptamer modified nanocomplexes for tumor vessel normalization and efficient erlotinib/Survivin-shRNA co-delivery to overcome drugresistance in EGFR-mutated NSCLC.

Although novel molecular targeted drugs have been recognized as an effective therapy for non-small lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) activating mutations, their efficacy fails to meet the expectation due to the acquired resistance in tumors. Up-regulation of the anti-apoptotic protein Survivin was shown to contribute to the resistance to EGFR tyrosine kinase inhibitors (TKI) in EGFR mutation-positive NSCLC. However, the unorganized tumors blood vessels impeded drug penetr...

Great efficacy of bevacizumab plus erlotinib for leptomeningeal metastases from non-small cell lung cancer with initially positive EGFR mutation: a case report.

Leptomeningeal metastases (LMs) were devastating metastatic complications of non-small cell lung cancer (NSCLC). Management of LMs relied on conventional therapy but with poor survival, lacking effective treatment strategies. We present the case of a 52-year-old female non-smoker with advanced lung adenocarcinoma and initially positive EGFR-mutation, who failed to the treatment of standard first-line chemotherapy (pemetrexed plus cisplatin) and bevacizumab (BEV), and maintenance therapy with pemetrexed plus...

Erlotinib effective in the neoadjuvant setting.

Can We Prevent Resistance to Osimertinib? Combination or Sequential.

Erlotinib in the treatment of recurrent or metastatic cutaneous squamous cell carcinoma: A single-arm phase 2 clinical trial.

Cutaneous squamous cell carcinoma (CSCC) is a very common malignancy in which most patients present with localized disease. Recurrent and metastatic disease is rare, and there is no standard therapy. These tumors frequently overexpress the epidermal growth factor receptor (EGFR). We conducted a phase 2 trial to determine the response rate to therapy with erlotinib, an EGFR tyrosine kinase inhibitor, in patients with locoregionally recurrent or metastatic CSCC that was not amenable to curative treatment (NCT...
