Filter by:To evaluate the effect of re-administration of gefitinib to EGFR-mutated NSCLC patients who had been treated with at least one line of TKIs followed by another line of treatment (non-TKI)
This is an open-label, non-randomized, multicenter phase Ib/II study, which is composed of a phase Ib dose escalation part and a phase II dose expansion part. Patients will receive selumetinib in combination with gefitinib 250mg daily. This study will enroll EGFR-mutated NSCLC patients who have developed acquired resistance to EGFR TKI treatment.
Lung cancer is the most common cancer in men and the fourth most common cancer in women worldwide. Until today no effective method permits the early detection of lung cancer. Consequently, lung cancer is often diagnosed owing to symptoms of advanced disease. To address this problem, detection methods with an improved sensitivity and specificity are urgently needed. Over the past decade, accumulating evidence shows that the metabolism of cancer cells differs from that of normal cells. More specifically, the entire metabolism of cancer cells is reorganized or reprogrammed to increase anabolic reactions that induce cell growth and survival. Metabolic reprogramming during the development of cancer is driven by aberrant signaling pathways due to the activation of oncogenes and the loss of tumor suppressor genes. Furthermore, the microenvironment of the tumor plays a role in metabolic reprogramming. The altered cancer metabolism is characterized by an increased glycolysis, the production of lactate and the biosynthesis of macromolecules, such as proteins, lipids and nucleotides. Cancer cells have a high glycolytic rate and eliminate most of the glucose-derived carbon as lactate rather than oxidizing it completely via oxidative phosphorylation, a phenomenon known as the Warburg effect. The breakdown of glucose and other nutrients leads to a high energy production and provides the Krebs cycle with intermediates, which consequently are allocated to metabolic pathways that support biosynthesis. Metabolites are the end products of cellular metabolism and are therefore closely related to the observed phenotype. Disturbances in biochemical pathways which occur during the development of cancer consequently provoke changes in the metabolic phenotype. As a result, low-molecular weight metabolites are very attractive biomarkers for different cancer types. Nuclear magnetic resonance (NMR) spectroscopy enables the identification and quantitative analysis of complex mixtures of metabolites, as in plasma and serum, without an extended sample preparation. The present study aims to determine the metabolic phenotype of lung cancer by means of proton (1H)-NMR spectroscopy. Once the phenotype determined (training cohort), this has to be validated by an independent cohort.
This research study is evaluating the experimental drug palbociclib in combination with another experimental drug PD-0325901 as a possible treatment for cancers with KRAS mutations, particularly for those which started in the lung.
Metformin is thought to activate AMP-activated protein kinase (AMPK), a major sensor of cellular energy levels and a key enzyme limiting cellular growth during times of cellular stress. Once activated, this enzyme restricts anabolic processes such as protein, cholesterol and fatty acid synthesis and inhibits mTOR, a protein kinase responsible for unregulated growth. MTOR is upregulated in a variety of tumors, including NSCLC providing rationale to take advantage of this pathway with metformin.
This study is a research initiative established to explore the use of magnetic resonance imaging (MRI) as a tool for detecting organ motion as it pertains to planning radiation therapy.
This randomized clinical trial studies pulmonary rehabilitation in improving lung function in patients with locally advanced non-small cell lung cancer undergoing chemoradiation. Individualized exercise rehabilitation programs may reduce breathing problems and improve quality of life in patients with non-small cell lung cancer. It is not yet known whether pulmonary rehabilitation is more effective when started during or after cancer treatment.
The purpose of this study is to help researchers investigate if a new imaging agent named 18F-FMISO can predict if patients with lung cancer will respond to standard therapy, as well as whether disease will reoccur in the future. The study will also investigate whether a 18F-FDG PET scan in the middle of radiation treatment can predict if lung cancer will respond to standard therapy. Information obtained from this study may help doctors design future studies in which they may target tumor areas that do not respond to therapy or may likely reoccur in the future.
platinum-based albumin-bound paclitaxel regimen in advanced non-small cell lung cancer (NSCLC) especially in lung squamous cell carcinoma has a better tumor response rate and safety than solvent-based paclitaxel.However, the safety and efficacy is uncertain in neoadjuvant therapy.
This is a randomized, double blind placebo controlled study to evaluate safety and efficacy of lucanthone administered as an adjunct to patients receiving whole brain radiation therapy (WBRT) as primary treatment for brain metastases secondary to non-small cell lung cancer.
