Active clinical trials for "Gastrointestinal Neoplasms"

The aim of this study is to test the hypothesis that adjuvant administration of probiotics in cancer patients undergoing chemotherapy can reduce a chemo-induced increased intestinal permeability. Furthermore, we hypothesize that the use of probiotics may reduce the occurrence of gastrointestinal side effects such as diarrhea, abdominal pains, bacterial translocation and infections following chemotherapy.

The purpose of this study is to evaluate the effect of entinostat on heart rate and other electrocardiogram (ECG) parameters. This study will also evaluate the safety and tolerability of entinostat, as well as pharmacokinetic and pharmacodynamic parameters.

AMG 211 is a bispecific single-chain antibody construct of the bispecific T-cell engager (BiTE®) class that targets human carcinoembryonic antigen (CEA, CD66e) on (tumor) cells and cluster of differentiation 3 (CD3) positive T-cells. AMG 211 is a potentially new targeted drug in the treatment of relapsed/refractory gastrointestinal adenocarcinoma, since those are CEA expressing tumors. A well-known challenge in current drug development using targeted therapies is the high level of heterogeneity of target expression that is present in specific tumor types. Radio-labeling of AMG 211 with the positron emission tomography (PET) radionuclide Zirconium-89 (89Zr) enables non-invasive imaging and quantification of AMG 211 distribution in cancer patients. By performing a 89Zr-AMG211 PET scan prior to treatment with AMG 211, the uptake of the tracer in the primary and metastatic tumor lesions and normal organ distribution can be evaluated. By performing a 89Zr-AMG211 PET scan during AMG 211 continuous intravenous (cIV) treatment the investigators will be able to evaluate the impact of prolonged steady state exposure of AMG 211 on tumor and tissue uptake. The 89Zr-AMG211 PET imaging study may help to identify patients more likely to benefit from AMG 211 therapy.

This is a single-arm, multicentre real-world observational study of TAS-102 in combination with regorafenib or fruquintinib for third-line and above advanced colorectal cancer.

Resveratrol has been shown to activate a protein called Notch-1. Signaling of Notch-1 has been shown to prevent tumor cell growth. Resveratrol has also been shown to prevent growth of tumors in mice. The purpose of this study is to examine the effects of resveratrol and Notch-1 on neuroendocrine tumor tissue and to examine how people with neuroendocrine tumors who take resveratrol for up to three months tolerate the product.

The primary objectives are to determine feasibility and the acute toxicity profile of proton therapy with concurrent continuous infusion 5-FU chemotherapy. Secondary objectives are to determine late toxicities and to generate preliminary data on clinical efficacy.

The FOLFOX6 regimen is a standard chemotherapy regimen for the treatment of patients with colorectal cancer and other gastrointestinal cancers. Tivozanib (AV-951) is a targeted anti-angiogenesis agent that has demonstrated acceptable tolerability in a phase I clinical trial. This study is designed to test the hypothesis that tivozanib (AV-951) can be combined with standard FOLFOX6 chemotherapy for the treatment of patients with colorectal and other gastrointestinal cancers. The purpose of this study is to determine the maximum dose of tivozanib (AV-951) that can be safely combined with FOLFOX6 chemotherapy, and to evaluate the safety profile, tolerability, and pharmacokinetics of this combination.

RATIONALE: Everolimus and vatalanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving everolimus together with vatalanib may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of everolimus and vatalanib in treating patients with advanced solid tumors.

This clinical study is being conducted at multiple sites to determine the best confirmed response rate, safety, and tolerability of GSK1363089 treatment in metastatic gastric carcinoma.

Research has shown that anti-angiogenic agents can be effective therapies to treat cancer. Anti-angiogenic agents target the blood vessels required for tumors to grow. Vascular endothelial growth factor (VEGF) is one of the cell pathways used for this blood vessel growth. When the investigators interfere with the VEGF pathway, the investigators inhibit this blood vessel growth which is required by tumors. One of the study drugs being used, tivozanib (AV-951), selectively interferes with the VEGF pathway. The second study drug being used, everolimus (RAD001) interferes with the mTOR pathway. The mTOR pathway is another pathway involved in blood vessel and tumor cell growth. By combining these two drugs the investigators hope to slow or reverse tumor cell growth in patients whose tumors have become resistant to other therapies for their disease.
