Active clinical trials for "Colorectal Neoplasms"

The purpose of this study is to determine whether the Litx™ system is safe and effective in combination with chemotherapy in the treatment of liver metastasis arising from colorectal cancer. Litx™ is a next-generation photodynamic therapy platform in which the drug, talaporfin sodium (LS11), is activated by light from the light-emitting diode (LED)-based light infusion device, inserted directly into the tumor through the skin prior to treatment.

This 2 arm study will compare the efficacy and safety of intermittent oral Xeloda plus Eloxatin (oxaliplatin) with that of fluorouracil/leucovorin in patients who have had surgery for colon cancer and no previous chemotherapy. Patients will be randomized to receive either 1) XELOX (Xeloda 1000mg/m2 po bid on days 1-15 + oxaliplatin) in 3 week cycles or 2)5-fluorouracil + leucovorin in 4 or 8 week cycles. The anticipated time on study treatment is until disease progression and the target sample size is 500+ individuals.

In this study, patients will receive either pemetrexed plus irinotecan or 5-fluorouracil (5-FU), leucovorin, and irinotecan. The purposes of this study are to determine: How pemetrexed plus irinotecan compares with 5-FU, leucovorin, and irinotecan in terms of efficacy. The safety of pemetrexed plus irinotecan and any side effects that might be associated with it as compared with 5-FU, leucovorin, and irinotecan. Whether pemetrexed can help patients with colorectal cancer.

The purpose of this clinical trial is to determine whether it is safe to treat patients with advanced colorectal cancer, with humanised A33 antibody tagged with radioactive iodine (131I-huA33) in combination with chemotherapy (capecitabine).

PURPOSE: This randomized phase III trial is studying two different combination chemotherapy regimens to compare how well they work in treating patients with colorectal cancer and resectable metastases.

The purpose of this study is to determine whether overall survival is prolonged in subjects with metastatic, epidermal growth factor receptor (EGFR)-positive colorectal cancer treated with cetuximab in combination with irinotecan compared with irinotecan alone as second-line therapy following treatment with a fluoropyrimidine and oxaliplatin based, non-irinotecan-containing regimen.

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. It is not yet known whether sulindac, aspirin, or ursodiol is more effective in preventing colorectal cancer. PURPOSE: This randomized phase II trial is studying how well sulindac works compared to aspirin or ursodiol in preventing colorectal cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving the drugs in different combinations may kill more tumor cells. PURPOSE: This randomized phase II trial is studying combination chemotherapy containing irinotecan and oxaliplatin to see how well it works compared to two standard combination chemotherapy regimens in treating patients with unresectable metastatic colorectal cancer.

The purpose of this study is to determine whether the Litx platform is safe and effective in the treatment of liver metastasis arising from colorectal cancer. Litx is a next-generation photodynamic therapy platform in which the drug, talaporfin sodium (LS11), is activated by light from the light-emitting diode (LED)-based light infusion device, inserted directly into the tumor through the skin prior to treatment.

This study is an open-label study. It has two stages. Stage 1 is a dose escalation phase of the study to determine and evaluate the safety and tolerability of repeated treatments with a genetically engineered herpes simplex virus NV1020 administered locoregionally to the liver. Stage 2 is to evaluate the dose found in Stage 1 to be "optimally tolerated". Stage 2 is to assess the efficacy of the optimally tolerated dose of NV1020 by itself and in combination with second-line chemotherapy. Assignment to Stage 1 or Stage 2 of the study is determined by when the patient enters the study.
