Active clinical trials for "Colorectal Neoplasms"

RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. PURPOSE: Phase I trial to study the effectiveness of monoclonal antibody therapy in treating patients who have colorectal cancer.

RATIONALE: Bortezomib may interfere with the growth of tumor cells by blocking the enzymes necessary for cancer cell growth. PURPOSE: Phase II trial to study the effectiveness of bortezomib in treating patients who have metastatic or recurrent colorectal cancer.

EP2101 is a new cancer vaccine containing 10 different peptide antigens. The vaccine is designed to activate the immune system to develop a response against tumor cells in order to delay or prevent the recurrence of cancer. This study will test the safety and measure the level of immune stimulating capability of EP2101 in patients with Colon Cancer.

RATIONALE: Drugs used in chemotherapy such as floxuridine and irinotecan use different ways to stop tumor cells from dividing so they stop growing or die. Hepatic arterial infusion uses a catheter to deliver chemotherapy directly to the liver. Combining more than one drug and giving them in different ways may kill any tumor cells remaining after surgery. PURPOSE: Phase II trial to study the effectiveness of systemic irinotecan and hepatic arterial infusion with floxuridine after surgery in treating patients who have hepatic (liver) metastases from 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. Oblimersen may increase the effectiveness of chemotherapy by making tumor cells more sensitive to the drugs. PURPOSE: Phase I/II trial to study the effectiveness of combining oxaliplatin, fluorouracil, and leucovorin with oblimersen in treating patients who have unresectable, metastatic, or recurrent colorectal cancer.

This is a phase II, multicenter, target enrollment of 250 evaluable patients, open-label study of cetuximab in patients with refractory, metastatic colorectal carcinoma. Based on prior studies, we predict that 70 to 75% of patients will be EGFR-positive. Patients must have documented failure after receiving either at least two chemotherapy regimens for metastatic disease or adjuvant therapy plus one chemotherapy regimen for metastatic disease provided that the patient progressed within 6 months of completing adjuvant therapy. Prior chemotherapy must have included irinotecan, oxaliplatin, and a fluoropyrimidine. Patients will receive an initial dose of cetuximab, 400 mg/m2, intravenously (i.v.) over 120 minutes, followed by weekly treatment with cetuximab, 250 mg/m2 i.v. over 60 minutes. Patients who experience unacceptable toxicity or who have progressive disease will not receive further cetuximab therapy. Patients will be evaluated for a tumor response at a minimum of every 6 weeks while on cetuximab therapy. Patients with stable disease or a partial or complete response may continue to receive weekly cetuximab therapy, unless they are dose-delayed or discontinued because of toxicity. Patients who have a partial or complete response must have a confirmatory tumor assessment no less than 4 weeks after the initial evaluation demonstrating a response. In addition, there is a pharmacokinetic companion protocol which will determine the trough and peak levels of cetuximab in 25 patients enrolled in the study at four to eight centers. A pharmacologic serum sample for the determination of levels of cetuximab will be obtained prior to the initial, fourth and sixth cetuximab infusions and 1 hour following the completion of the initial, fourth and sixth cetuximab infusions in the first course; and prior to and 1 hour post the completion of the first cetuximab infusion of each subsequent course of therapy. A course of therapy is defined as six weekly infusions of cetuximab monotherapy. ImClone will perform the pharmacokinetic analyses.

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. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients with liver metastases from 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 which regimen of combination chemotherapy is most effective in treating advanced colorectal cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of various combination chemotherapy regimens in treating patients who have advanced, recurrent, or metastatic colorectal cancer that cannot be treated with surgery or radiation therapy.

RATIONALE: Drugs used in chemotherapy, such as irinotecan, fluorouracil, and leucovorin, work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining more than one chemotherapy drug with radiation therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with radiation therapy works in treating patients with stage III or stage IV colorectal carcinoma (cancer), other refractory carcinoma (cancer), or metastatic adenocarcinoma (cancer) of unknown primary origin.

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 irofulven in treating patients with metastatic colorectal cancer.
