Active clinical trials for "Colonic Neoplasms"

This single arm study will evaluate the safety profile of Xeloda as monotherapy for adjuvant treatment of colon cancer. All patients will receive Xeloda 1250mg/m2 p.o. twice daily as intermittent treatment (3 week cycles consisting of 2 weeks of treatment followed by 1 week without treatment). The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.

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 is a way to kill more tumor cells. PURPOSE: Randomized phase III trial to determine the effectiveness of uracil, tegafur,and leucovorin compared with fluorouracil plus leucovorin in patients with resected stage II or stage III colon cancer.

This randomized phase I/II trial studies the side effects, best way to give, and best dose of erlotinib and bevacizumab when given with cetuximab and how well giving erlotinib and cetuximab together with or without bevacizumab works in treating patients with metastatic or unresectable kidney, colorectal, head and neck, pancreatic, or non-small cell lung cancer. Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as cetuximab and 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. Cetuximab and bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving erlotinib together with cetuximab and/or bevacizumab may kill more tumor cells.

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. It is not yet known whether celecoxib is effective in preventing polyps in patients with colon cancer. PURPOSE: Randomized phase III trial to study the effectiveness of celecoxib in preventing the development of polyps in patients who have undergone surgery for stage I colon cancer.

Enzastaurin given daily to participants with colorectal cancer who have Stage 4 disease and have not received prior chemotherapy for advanced colorectal cancer

RATIONALE: Vaccines made from a peptide may make the body build an immune response and kill tumor cells. PURPOSE: Randomized phase I trial to study the effectiveness of vaccine therapy in treating patients who have metastatic cancer that has not responded to previous therapy.

This 2 arm study will compare the safety and efficacy of oral Xeloda, or 5-fluorouracil in combination with leucovorin, in patients who have undergone surgery for colon cancer. Patients will be randomized to receive either Xeloda 1250mg/m2 po bid on days 1-14 every 21 days, or leucovorin 20mg/m2 iv + 5-fluorouracil 425mg/m2 iv daily from day 1 to day 5 every 28 days. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.

RATIONALE: Vaccines made from a patient's white blood cells and tumor cells may make the body build an immune response to kill tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining vaccine therapy with chemotherapy may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of vaccine therapy combined with leucovorin and fluorouracil in treating patients who have undergone surgery to completely remove stage II or stage III colon 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 if combination chemotherapy is more effective with or without irinotecan in treating colon cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without irinotecan in treating patients who have stage III colon cancer.

A monocentric window of opportunity study preceded by a safety run-in phase. The study population will include locally advanced colon patients (T3 or T4).
