Filter by:The purpose of the study is to tests the hypothesis, that N-acetylcysteine (a thiol-antioxidant)improves the exercise training effect on cancer patients that experience weight loss (cachexia) as assessed by muscle mass and function as well as histomorphology.
Pemetrexed has shown an anti-tumor activity in advanced gastric cancer patients in a previous study, while cisplatin is widely used in the combination chemotherapy of gastric cancer. Pemetrexed has shown synergy with cisplatin in preclinical models and in various human cancers. The introduction of vitamin supplementation has made treatment with pemetrexed plus cisplatin safe and well tolerated. The present phase 2 study is an effort to determine the efficacy and safety of the combination of pemetrexed and cisplatin in Korean patients with gastric carcinoma who had no prior palliative chemotherapy for advanced disease. The patients, who will give their consent for participating in this study, will be screened for their eligibility and on meeting pre-defined study eligibility criteria, they will receive an intravenous therapy of the combination of pemetrexed and cisplatin for number of times that in the opinion of their treating physician is appropriate for them. A response rate of 30% is considered as the minimum activity level of interest for this patient population.
This study is for people with advanced cancer of the digestive tract and cancer that cannot be completely removed by surgery. Radiation therapy is commonly used in the treatment of these types of cancer in combination with a chemotherapy drug, called 5-fluorouracil (5-FU). In this study, doctors will administer the standard dose of radiation therapy in combination with an investigational chemotherapy drug, called irinotecan. Irinotecan can decrease the size of tumors and also appears to increase the effectiveness of radiation. The purpose of this study is to determine the highest dose of irinotecan that can be given safely in combination with radiation therapy, and to determine the side effects when these two treatments are given together. Irinotecan is approved by the Food and Drug Administration (FDA) for the treatment of colon cancer, but is not approved for cancers of the digestive tract. However, the FDA is allowing its use in this research study.
This phase II trial is studying how well sorafenib tosylate works in treating patients with progressive metastatic neuroendocrine tumors. Sorafenib tosylate 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.
The primary purpose of this study is to evaluate the safety, side effects, and dosage for Motexafin Gadolinium given with the chemotherapy drug docetaxel to patients with advanced cancers. Secondly, tumor response to the combined treatment, drug levels in the body, and drug interactions will be evaluated.
This trial is a phase II study in patients with advanced gastrointestinal (GI) malignancies who will be assigned to one of 4 cohorts (normal, mild, moderate and several renal dysfunction) based on their baseline measured creatinine clearance then treated with FOLFOX4. Standard bone marrow and liver function inclusion and exclusion criteria must be met prior to study treatment. FOLFOX4 in the study is given every 2 weeks (1 cycle = 2 weeks) for up to 12 cycles unless there are treatment delays to allow for recovery from toxic effects. Dose modifications are included for protocol specified toxicities. After 12 treatment cycles on study, patients who are having a beneficial disease response may continue to have oxaliplatin supplied off study to continue the treatment regimen until disease progression, prohibitive toxicity or death. Oxaliplatin pharmacokinetic studies (plasma and urine) are planned during cycles 1 and 2 on each patient. Creatinine clearance will be assessed every 2 cycles and disease status will be assessed every 3 cycles of treatment during the study.
The purpose of this study is to permit access to SU011248 for treatment use by patients with GIST given the following conditions: a) patients undergo screening, but are not eligible for participation in ongoing clinical studies such as A6181004; AND b) patients have GIST which standard treatments have not been able to control with acceptable toxicity AND c) patients have the potential to derive clinical benefit from treatment with SU011248.
This phase II trial is studying how well CCI-779 works in treating patients with progressive metastatic neuroendocrine tumors. Drugs used in chemotherapy, such as CCI-779, work in different ways to stop tumor cells from dividing so they stop growing or die.
This study will determine the safety and effectiveness of AMG 706 in patients with advanced GIST.
This clinical trial is studying the amount of EF5 and motexafin lutetium present in tumor cells and/or normal tissues of patients with abdominal (such as ovarian, colon, or stomach cancer) or non-small cell lung cancer. EF5 may be effective in measuring oxygen in tumor tissue. Photosensitizing drugs such as motexafin lutetium are absorbed by tumor cells and, when exposed to light, become active and kill the tumor cells. Knowing the level of oxygen in tumor tissue and the level of motexafin lutetium absorbed by tumors and normal tissue may help predict the effectiveness of anticancer therapy
