Active clinical trials for "Colorectal Neoplasms"

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of R115777 in treating patients who have recurrent or advanced colorectal cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of chloroquinoxaline sulfonamide in treating patients who have stage IV colorectal cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. It is not yet known whether chemotherapy is more effective than observation in patients who have had surgery to remove colorectal cancer. PURPOSE: This randomized phase III trial is studying leucovorin and fluorouracil to see how well they work compared to observation in treating patients with colorectal cancer that has been surgically removed.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving drugs in different ways may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of liver perfusion using oxaliplatin plus leucovorin and fluorouracil given by infusion in treating patients who have colorectal cancer that has spread to the liver.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if the effectiveness of irinotecan combined with fluorouracil in treating colorectal cancer varies depending on the patient's racial background. PURPOSE: Phase III trial to study the effectiveness of irinotecan combined with fluorouracil in treating patients from different racial backgrounds who have colorectal cancer that is advanced, recurrent, metastatic or has not responded to treatment with fluorouracil.

RATIONALE: Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as oxaliplatin, leucovorin, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Erlotinib may help chemotherapy work better by making tumor cells more sensitive to the drugs. Giving erlotinib together with combination chemotherapy and bevacizumab may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of erlotinib when given together with combination chemotherapy and bevacizumab as first-line therapy in treating patients with metastatic colorectal cancer.

This 2-arm study evaluated the efficacy and safety of 2 different treatment schedules of oral Xeloda with intravenous (IV) Eloxatin (oxaliplatin) and IV bevacizumab (Avastin) as a first-line treatment in patients with locally advanced or metastatic colorectal cancer. Patients were randomized to receive either: 1) Xeloda 850 mg/m^2 orally twice a day (po bid) on Days 1-14, oxaliplatin 130 mg/m^2 IV on Day 1, and Avastin 7.5 mg/kg IV on Day 1 of each 3-week cycle; or 2) Xeloda 1500 mg/m^2 po bid on Days 1-7, oxaliplatin 85 mg/m^2 IV on Day 1 and Avastin 5 mg/kg IV on Day 1 of each 2-week cycle. The anticipated time on study treatment was 1-2 years, and the target sample size was 100-500 individuals.

The purpose of this study is to assess whether treatment with the study drug, panitumumab given concomitantly with every 2 (Q2) week oxaliplatin-based chemotherapy and bevacizumab improves progression-free survival (PFS) compared to treatment Q2-week with oxaliplatin-based chemotherapy and bevacizumab alone. All subjects will receive Q2-week oxaliplatin- or irinotecan-based chemotherapy and bevacizumab. Control arm subjects will not receive concomitant panitumumab therapy.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Erlotinib may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. Combining erlotinib with combination chemotherapy may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of combining erlotinib with oxaliplatin, leucovorin, and fluorouracil in treating patients who have metastatic colorectal cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of capecitabine in treating older patients who have metastatic or recurrent colorectal cancer that cannot be surgically removed.
