MET is expressed on neuroblastoma cells and may trigger tumor growth, neoangiogenesis and metastasis. MET upregulation further represents an escape mechanism to various anticancer treatments including VEGF signaling inhibitors. We developed in vitro a resistance model to pan-VEGFR inhibition and explored the simultaneous inhibition of VEGFR and MET in neuroblastoma models in vitro and in vivo using cabozantinib, an inhibitor of the tyrosine kinases including VEGFR2, MET, AXL and RET. Resistance in IGR-N91-Luc neuroblastoma cells under continuous in vitro exposure pressure to VEGFR1-3 inhibition using axitinib was associated with HGF and p-ERK overexpression...

A 36-year-old woman had undergone left radical nephrectomy followed by interferon-α and sunitinib for the treatment of renal cell carcinoma with para-aortic lymph node and lung involvements (papillary renal cell carcinoma, G3, cT3aN1M1) in the previous hospital. She was referred to our hospital for further treatment and received serial molecular targeted agents (everolimus, sorafenib, sunitinib) and radiation therapy for right ischial and femoral bone metastases. Then she was found to have multiple metastatic lesions in the lungs and carcinomatous pleural effusion associated with dyspnea...

Melanoma brain metastases (MBM) occur in 10% to 50% of melanoma patients. They are often associated with a high morbidity and despite the improvements in the treatment of advanced melanoma, including immunotherapy, patients with MBM still have a poor prognosis. Antiangiogenic treatment was shown to reduce the immunosuppressive tumor microenvironment. Therefore we investigated the effect of the combination of VEGFR- and CTLA-4 blockade on the immune cells within the tumor microenvironment. In this study we investigated the effect of the combination of axitinib, a TKI against VEGFR-1, -2 and -3, with therapeutic inhibition of CTLA-4 in subcutaneous and intracranial mouse melanoma models...

BACKGROUND: Sunitinib, pazopanib, sorafenib, axitinib and bevacizumab are the five recommended antiangiogenic agents in first-line therapy for metastatic renal cell carcinoma (mRCC). Because these drugs underwent simultaneous clinical development, no direct efficacy and safety comparison was ever conducted, thus preventing optimal therapy choices. METHODS: We performed a traditional and network meta-analysis to evaluate the efficacy and safety of mRCC-recommended first-line antiangiogenic agents...

Myxoid liposarcoma is a rare form of soft-tissue sarcoma. Although most patients initially respond well to treatment, approximately 21% relapse, highlighting the need for alternative treatments. To identify novel treatment regimens and gain a better understanding of myxoid liposarcoma tumor biology, we screened various candidate and approved targeted therapeutics and chemotherapeutics against myxoid liposarcoma cell lines. Therapeutics that target angiogenesis showed antitumor activity. The small molecule inhibitor axitinib, which targets angiogenesis by inhibiting the VEGFR and PDGFR families and c-Kit, inhibited cell cycle progression and induced apoptosis in vitro, as well as having significant antitumor activity against MLS 1765 myxoid liposarcoma xenografts in mice...

The mechanisms leading to the development and progression of hepatocellular carcinoma (HCC) are complicated and regulated genetically and epigenetically. The recent advancement in high-throughput sequencing has facilitated investigations into the role of genetic and epigenetic regulations in hepatocarcinogenesis. Therefore, we used systems biology and big database mining to construct genetic and epigenetic networks (GENs) using the information about mRNA, miRNA, and methylation profiles of HCC patients. Our approach involves analyzing gene regulatory networks (GRNs), protein-protein networks (PPINs), and epigenetic networks at different stages of hepatocarcinogenesis...

PURPOSE: This study utilizes FLT PET/CT imaging to characterize changes in tumor cell proliferation and vasculature during intermittent treatment with VEGR-TKI axitinib. METHODS: Patients with metastatic solid malignancies underwent 3-week treatment cycles with axitinib (7 and 5 mg BID for safety and pharmacodynamic cohorts, respectively). Cycles consisted of 2 weeks of treatment (dosing period) followed by a 1-week treatment break (washout period). Patients in the pharmacodynamic cohort had up to six FLT PET/CT scans (three scans in each cycle 1 and cycle 3) and had plasma VEGF concentrations measured at imaging timepoints...

We systematically compared the adverse effects of cancer drugs to detect event outliers across different clinical trials using a data-driven approach. Because many cancer drugs are toxic to patients, better understanding of adverse events of cancer drugs is critical for developing therapies that could minimize the toxic effects. However, due to the large variabilities of adverse events across different cancer drugs, methods to efficiently compare adverse effects across different cancer drugs are lacking. To address this challenge, we present an exploration study that integrates multiple adverse event reports from clinical trials in order to systematically compare adverse events across different cancer drugs...

Axitinib is a vascular endothelial growth factor receptor inhibitor indicated for advanced renal cell cancer after failure of one prior systemic therapy. We report a case where a patient receiving axitinib experienced a supratherapeutic INR soon after initiation of an age-appropriate warfarin dose. We propose two possible mechanisms for this interaction, including competitive protein binding and decreased metabolism. Close INR monitoring and dose adjustments of warfarin may be necessary in patients receiving concomitant axitinib and warfarin in order to decrease the risks associated with this interaction...

Although bronchial angiogenesis has been well documented in allergic asthma, lymphangiogenesis has not been widely studied. Therefore, we evaluated changes in lung lymphatics in a rat model of allergen-induced asthma using house dust mite (Der p 1; 100 μg/challenge). Additionally, properties of isolated lung lymphatic endothelial cells (CD45(-), CD141(+), LYVE-1(+), Prox-1(+)) were studied in vitro. Three weeks after the onset of intranasal allergen exposure (twice-weekly), an increase in the number of lung lymphatic vessels was measured (34% increase) by lung morphometry...

PURPOSE: Axitinib, a tyrosine kinase inhibitor targeting vascular endothelial growth factor receptors 1-3, is approved for second-line treatment of advanced renal cell carcinoma. Axitinib is partially metabolized by cytochrome P450 1A2, which is induced by chronic heavy smoking. The effect of smoking on axitinib pharmacokinetics was evaluated in a non-small-cell lung cancer (NSCLC) patient population with a large number of active and ex-smokers. METHODS: Data were pooled from six clinical studies-serial pharmacokinetics from two healthy volunteer studies (n = 58) and sparse pharmacokinetics from four NSCLC studies (n = 152)-for a nonlinear mixed effects modeling (NONMEM v7...

Sophora interrupta Bedd, (Fabaceae) is used in Indian folk medicine to treat cancer. Angiogenesis is one of the crucial characteristics of cancer metastasis and is regulated by vascular endothelial growth factor (VEGF). In this study, we examined the antiangiogenic properties of the root ethyl acetate extract of Sophora interrupta by various methods. In vitro antioxidant activity (100-600 μg/ml) of S. interrupta ethyl acetate (SEA) extract was evaluated by DPPH and ABTS, anti-inflammatory activity (50, 100 and 150 μg/ml) by estimating nitric oxide (NO) levels, anti-angiogenic activity (200 and 500 μg/ml) was validated by chorio allantoic membrane (CAM) assay and in silico molecular dynamic (MD) simulations analyses (25 ns) were performed to identify the anti-angiogenic compounds extracted from root extract...

BACKGROUND: Pembrolizumab is a monoclonal antibody that is designed against programmed cell death protein 1 (PD-1). Pembrolizumab and other immunocheckpoint-blocking monoclonal antibodies work by modulating a patient's own immune system to increase anti-tumor activity. While immunocheckpoint blockade has shown promising results, only 20-40 % of patients experience objective clinical benefit. Differences in individual tumor biology and the presence multiple immune checkpoints present a challenge for treatment...

INTRODUCTION: Renal cell carcinoma (RCC) is the most common type of kidney cancer in adults, and its pathogenesis is strictly related to altered cellular response to hypoxia, in which mTOR signaling pathway is implicated. Everolimus, an mTOR serine/threonine kinase inhibitor, represents a therapeutic option for the treatment of advanced RCC. AIM: The objective of this article is to review the evidence for the treatment of metastatic RCC with everolimus. EVIDENCE REVIEW: Everolimus was approved for second- and third-line therapy in patients with advanced RCC according to the results of a Phase III pivotal trial that demonstrated a benefit in median progression-free survival of ~2 months compared to placebo after failure of previous lines of therapy, of which at least one was an anti-VEGFR tyrosine kinase inhibitor (TKI)...
