Active clinical trials for "Colorectal Neoplasms"

This phase II study will evaluate the effect of bevacizumab, capecitabine and oxaliplatin with radiation on rectal cancer. Researchers will also evaluate the tolerability (how it makes the patient feel) and safety of this combination by watching for harmful side-effects.It is hoped that by adding bevacizumab to the capecitabine/oxaliplatin treatment in combination with radiation before surgery will improve response rate.

RATIONALE: Drugs used in chemotherapy, such as irinotecan, work in different ways to stop tumor cells from dividing so they stop growing or die. Celecoxib may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Giving irinotecan with celecoxib may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of irinotecan when given with celecoxib in treating patients with unresectable or metastatic colorectal cancer.

RATIONALE: Drugs used in chemotherapy, such as irinotecan, fluorouracil, leucovorin, and oxaliplatin, work in 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 as first-line therapy in treating patients who have metastatic colorectal cancer.

RATIONALE: OSI-7904L may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Drugs used in chemotherapy, such as oxaliplatin, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining OSI-7904L with oxaliplatin may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of OSI-7904L and oxaliplatin in treating patients with refractory or recurrent advanced colorectal cancer.

The purpose of the study is to determine if ABT-751 will decrease tumors, and determine how long the tumor shrinkage can be maintained in patients with colorectal cancer. Patients will receive ABT-751 by mouth daily for 21 days. Patients will be off drug for 7 days before starting the next cycle of drug.

This study is for people with colorectal cancer, who have tumors that cannot be completely removed by surgery. This study is being done to find out how long it takes tumors to grow after patients receive the drugs capecitabine, oxaliplatin and bevacizumab. Capecitabine (also called Xeloda) is a drug that has been approved by the FDA for treatment of advanced colorectal cancer. Capecitabine prevents some colorectal cancer cancer cells from reproducing, and causes some of them to die. Oxaliplatin (also called Eloxatin) has also been approved by the FDA for treatment of advanced colorectal cancer. Oxaliplatin prevents some colorectal cancer cells from reproducing. Bevacizumab is an investigational drug. Bevacizumab is an antibody (a protein that acts against a specific substance) directed against vascular endothelial growth factor (VEGF). VEGF promotes the growth of blood vessels that bring nutrients to cells. Bevacizumab inhibits the growth of colon cancer cells, by blocking the effects of VEGF. The combination of the drugs used in this study is experimental. The purpose of this study is to see how long it takes patients' tumors to grow when they are taking this combination of drugs.

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 cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Clinical trial to study the effectiveness of combination chemotherapy in treating patients who have advanced colorectal cancer.

This study will assess the efficacy and safety of continuous oral Xeloda administration in combination with intravenous irinotecan as a first-line treatment in patients with advanced and/or metastatic colorectal cancer. The anticipated time on study treatment is 3-12 months and the target sample size is <100 individuals.

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.
