Active clinical trials for "Glioblastoma"

In this explorative study immunological changes during tumor therapy will be analyzed in patients with malignant glioma. Immunophenotyping before and during therapy is used as analysis method. Thereby immune cells are quantitatively and qualitatively detected from patient's blood at continuous time points. Additionally relevant mediators like cytokines, danger signals and chemokines are analyzed by other methods. Obtained results may give information about the effects of therapy on immunological processes and immune cells and may help to find immunological based predictive or prognostic tumor markers and to define time points for including additional immune therapy in the future.

The purpose of this study is: To learn if (MMP-2, MMP-9 and NGAL) which are substances found in blood and urine associated with tumors, can be used as tumor markers in the management and treatment of glioblastoma. To study the relationship between MMP-2, MMP-9 and NGAL with quality of life and disease symptoms.

The purpose of this surveillance is to evaluate the postmarketing safety and efficacy of Temodal capsule (temozolomide) under actual conditions of use, and to understand some of the following points that are in question and doubt: Incidence of adverse events under actual conditions of use (Serious and Nonserious Adverse Events); Adverse Drug Reactions not shown in the directions for use (will be stated as Unexpected Adverse Reaction); Adverse Event caused by misuse, abuse, or drug interactions; Other information concerned with safety or efficacy.

The aim of this study is to establish FET-PET as an additional therapy assessment parameter in patients diagnosed with a glioblastoma multiforme receiving radiochemotherapy and adjuvant chemotherapy after previous resection or biopsy.

RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This laboratory study is looking at tissue samples from patients with glioblastoma multiforme to identify biomarkers that may improve the selection of patients for epidermal growth factor receptor inhibitor therapies.

Hypoxia is recognized to be an independent predictor of clinical outcome in oncology. PET using [18F]-FMISO has been described to be useful for the non invasive assessment of hypoxia in cancer. The use of this radiotracer for brain tumours is very limited and there is no standard to acquire and quantify [18F]-FMISO uptake. So there is a need for a methodological evaluation of this PET tracer The purpose of this research is to define optimal parameters for acquisition and data exploitation to quantify [18F]-FMISO uptake and so predict clinical outcome in glioblastomas. Low sensitivity to radiation of glioblastoma is partly caused by hypoxia. Hypoxia in tumours is not predicted by tumour size. Detecting and monitoring tissue oxygenation are of great interest to modify therapeutic strategies, including local dose escalation for radiotherapy or select chemotherapeutic agents with better impact in glioblastomas. PET with appropriate radiotracers, especially [18F]-FMISO, enables non-invasive assessment of hypoxia. [18F]-FMISO only accumulates in viable hypoxic cells. So, it has been demonstrated that PET using 18F-FMISO is suitable to localize and quantify hypoxia. But there isn't any optimal acquisition protocol or standardized images quantification treatment. Thus, the interpretation of [18F]-FMISO PET images and the predictive value of [18F]-FMISO SUV (Standardized Uptake Value) remain unclear explaining the need of methodological approaches.

This study is for subjects with a diagnosis of a brain tumor called glioblastoma that is being treated with bevacizumab. This study will use a new MRI technique to compare the images of blood vessels and tumor structure to the effectiveness of bevacizumab.

This pilot, non-interventional, observational, Web-based, prospective cohort study is designed to collect self-reported safety and effectiveness and genetic data from subjects with locally recurrent breast cancer (BC) or metastatic breast cancer (MBC), metastatic colorectal cancer (MCRC), metastatic non-squamous non-small cell lung cancer (MNSCLC), recurrent glioblastoma (RGBM), or metastatic renal cell cancer (MRCC) in the United States who have been previously treated with Avastin (bevacizumab). The cohort will be composed of male and female subjects who have been diagnosed with locally recurrent BC or MBC, MCRC, MNSCLC, RGBM, or MRCC who have received treatment with bevacizumab in combination with chemotherapy, which started prior to or up to 31 December 2012. Participants will be self-referred to this study. They will be recruited online via a number of sources, including through the involvement of patient advocacy groups, social media tools, traditional media, physicians, and events to raise awareness of this study. After appropriate informed consent and authorization are obtained, data will be collected directly from subjects in an online survey. Participants will be contacted electronically to complete quarterly follow-up surveys. The follow-up period will be 1 year from responding to the baseline survey. DNA collection will be performed as part of this study. DNA will be extracted from saliva, which will be provided by the subject utilizing a collection kit sent to the participants for at-home use.

Presently, patients with primary malignant brain tumors have a life expectancy of 15 weeks following surgery unless they receive additional types of therapy (chemotherapy, radiotherapy, and/or immunotherapy). Patients that receive additional therapy can increase life expectancy to 50 weeks. The statistics on the life expectancy and survival have increased efforts among researchers to develop new treatments for primary malignant brain tumors. This research project involves the growth and study of human brain tumor cells outside the body in the laboratory as part of an attempt to better understand these tumors and to develop more effective treatments for them.

Patients with a new diagnosis of high-grade glioma based on MRI, who are considered surgical candidates determined by neurosurgeons or patients with recurrent glioblastoma with the initial diagnosis of glioblastoma (histologic or molecular proof) and recommended for clinically surgical resection may be eligible for this study. Subjects may participate in this study if they are at least 18 years of age. Ferumoxytol-enhanced MRI will be used to quantify tumor-associated macrophages. This is a non-therapeutic trial in that imaging will not be used to direct treatment decisions. The blood draw is being completed to evaluate cell-free circulating tumor DNA (cfDNA) and cell-free tumor DNA (ctDNA).
