Active clinical trials for "Colorectal Neoplasms"

The purpose of this study is to determine confirmed objective response rate to combination therapy with cetuximab and FOLFOX4 or FOLFOX4 alone in patients with CRC and non-resectable hepatic metastases

The purpose of this study is to evaluate the safety and effectiveness of the bevacizumab and capecitabine combination in frail patients with untreated metastatic colorectal cancer.

The primary objective of this study is to compare the activity of raltitrexed and ZD1839 versus raltitrexed alone as second line chemotherapy in subjects with colorectal carcinoma by estimating progression free survival (PFS) in each treatment arm.

The purpose of this study is to compare the rates of Progression-Free Survival (PFS) at 12 months for patients treated with Bev-FOLFOX versus patients treated with FOLF-CB for first line treatment of metastatic colorectal cancer.

To assess the efficacy and safety of the combination of capecitabine and oxaliplatin in the 1st, 2nd or subsequent line treatment of metastatic colorectal cancer, and also in the neo-adjuvant and adjuvant setting of resectable metastases. Primary Endpoint: Objective response rates Secondary Endpoints: Treatment related toxicity Progression free survival (If not resected) Disease free Survival (From metastastectomy, if resected) Overall Survival 60 Day all cause mortality Number undergoing liver resections/curative resection (Ro) rate

Dendritic cells (DCs) are the professional antigen-presenting cells of the immune system. As such they are currently used in clinical vaccination protocols in cancer patients. We evaluate the ability of mature DCs pulsed with carcinoembryonic antigen (CEA)-peptide (arm A) or electroporated with CEA-mRNA (arm B) to induce CEA-specific T cell responses in patients with resectable liver metastases from colorectal cancer. To evaluate immune responses, CEA-specific T cell reactivity is monitored in peripheral blood, resected abdominal lymph nodes, tumor tissue and biopsies of vaccination sites and post-treatment DTH skin tests. Patients are vaccinated intradermally and intravenously with CEA-peptide pulsed mature DCs three times prior to resection of liver metastases. In 2007 a side-study has been added (arm C), in which patients with stage III or high-risk stage II colorectal cancer that are amenable for standard adjuvant oxaliplatin/capecitabine therapy are vaccinated with CEApeptide-pulsed DCs. Also in this group, safety and immune responses in peripheral blood and the DTH-skin test are the primary endpoints. Results are compared with the results obtained in arm A.

Until recently, bolus 5-flourouracil (FU) + folinic acid (FA) has been considered the standard chemotherapy for patients with colorectal cancer. Several studies have shown that Capecitabine is as effective as Mayo regimen. The Nordic FU/FA schedule was developed to be an active and tolerable bolus regimen. The Nordic regimen consists of a short (3 minutes) bolus injection of FU and 30 minutes later FA for 2 consecutive days each 2 weeks. In randomized studies efficacy is comparable to other FU/FA regimens. It is claimed that patients prefer oral therapy and in a randomized study comparing oral therapy (UFT/FA) and bolus FU/FA (Mayo) 84% preferred oral therapy. In the present randomized cross-over study patients were randomized for 3 courses of Nordic FU/FA followed by 2 courses of Capecitabine (or vice versa), and patients were asked for their preference.

XELOX (Capecitabine and Oxaliplatin) is an effective and convenient regimen for patients with metastatic colorectal cancer. Chronomodulated therapy may reduce toxicity. Patients will be randomized to standard XELOX (Capecitabine 1000 mg/m² in the morning and 1000 mg/m² in the evening days 1-14 and short term Oxaliplatin 130 mg/m² day 1 in 30 minutes) or chronomodulated XELOX (Capecitabine 400 mg/m² in the morning and 1600 mg/m² in the evening days 1-14 and short term Oxaliplatin 130 mg/m² day 1 in 30 minutes). Bloodsamples will be collected and frozen and later examined for potential predictive factors

This study will test the safety and efficacy of TroVax in patients undergoing surgical resection of colorectal cancer with liver metastases. TroVax potentially works by encouraging the immune system to react against the 5T4 protein on the surface of bowel cancer cells. The immune system is then able to recognise 5T4 and kill cells that carry it. The hope is that if tumour cells started to grow again after the main tumour has been surgically removed, the immune system would be able to find and destroy them.

The purpose of this study is to see if Cediranib in combination with FOLFOX is effective in treating metastatic colorectal cancer and to see how it compares with Avastin (Bevacizumab) in combination with FOLFOX.
