Active clinical trials for "Colorectal Neoplasms"

This study will evaluate the efficacy of Irinotecan,Capecitabine and Avastin combination in patients with no response to previous treatment with 5-Fluorouracil,Leucovorin,Eloxatin and Avastin.

To assess the efficacy of methotrexate in a genetically selected population of patients with advanced colorectal cancer, who have loss of a particular gene, MSH2. The efficacy of methotrexate will be evaluated by the proportion of cases that have a significant response to treatment (objective response rate).

Bevacizumab is an angiogenesis inhibitor which means it works to stop blood vessel formation in tumors. Without new blood vessels, the growth of a tumor is slowed. Chemotherapy works to kill cancer cells directly. This study is being done to see how colorectal cancer responds to treatment with the combination of bevacizumab and chemotherapy.

The purpose of this study is to determine the effect of amifostine (ETHYOL) on decreasing the rate and severity of nerve dysfunction or neuropathy (numbness and tingling in hands and feet) associated with FOLFOX chemotherapy.

RATIONALE: Inserting the interleukin-12 gene into a person's cancer cells may make the body build an immune response to kill tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of interleukin-12 gene when injected into the tumors of patients with liver metastases secondary to colorectal cancer.

RATIONALE: 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. Bevacizumab may also stop the growth of colorectal cancer by blocking blood flow to the tumor. Drugs used in chemotherapy, such as capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bevacizumab together with capecitabine may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving bevacizumab together with capecitabine works as first-line therapy in treating older patients with metastatic colorectal cancer.

The primary rationale for this study is to develop an optimized schedule of administration of FOLFOX + bevacizumab that maximizes the efficacy and safety of this regimen when administered to patients with advanced colorectal cancer. The hypothesis is that the use of an intermittent oxaliplatin (IO) schedule of FOLFOX/bevacizumab will allow these patients to continue on treatment for a longer period of time by reducing the proportion of patients who discontinue therapy early because of treatment-related toxicities and thus increasing the possibility of a longer time to progression. The primary objective is: To test the hypothesis that an intermittent oxaliplatin (IO) schedule of FOLFOX/bevacizumab will allow patients to remain on therapy for a longer period of time compared to a conventional "treat-to-failure" schedule, by reducing the proportion of patients who discontinue therapy for treatment-related toxicities. The secondary objectives are: To evaluate the impact of calcium/magnesium infusions on the incidence and severity of neurotoxicity in subjects receiving either the IO or conventional FOLFOX/bevacizumab treatment schedules as first-line treatment for metastatic colorectal cancer. To evaluate the safety and efficacy of the IO versus the conventional schedule + calcium and magnesium infusions, as part of oxaliplatin-based first-line therapy for metastatic colorectal cancer.

Currently there is no one standard of care for older patients with metastatic colorectal cancer. The study will examine the tumor response to capecitabine, oxaliplatin, plus bevacizumab. The study will also gather information on the usefulness and side effects of this treatment combination.

A study to evaluate rofecoxib in the treatment of rectal, colon, or duodenal adenomas in patients with Familial Adenomatous Polyposis.

Triplets of irinotecan, oxaliplatin and infusional 5-fluorouracil(FU)/leucovorin (LV) are associated with high response rates and long survival as first-line treatment for metastatic colorectal cancer (mCRC). The oral fluoropyrimidine, capecitabine, is better tolerated and shows better response rates than 5-FU/LV in metastatic colorectal cancer. A phase I dose-escalation study established dose limiting toxicity (DLT), maximum tolerated dose (MTD) and recommended phase II doses (RPIID) of irinotecan, oxaliplatin and capecitabine. This phase I /II study is to determine dose-limiting toxicities (DLTs), maximum tolerated dose (MTD), phase II recommended dose (RD) of IXO and bevacizumab combination and safety at the RD in an expanded cohort.
