Active clinical trials for "Colorectal Neoplasms"

RATIONALE: Drugs used in chemotherapy, such as S-1, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. 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. Giving S-1 together with bevacizumab may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving S-1 together with bevacizumab works as third-line therapy in treating patients with colorectal cancer that is recurrent or that cannot be removed by surgery.

This is a Phase 2, multicenter, multiple-arm, open-label study to evaluate the efficacy, safety, and tolerability of EZN-2208. EZN-2208 will be administered as a single agent in patients with K-RAS mutations in the tumors. Patients with wild type K-RAS in tumors will be randomized to EZN-2208 + cetuximab or to standard of care (Camptosar® + cetuximab), patients must have failed regimens containing irinotecan (Camptosar®, CPT-11), oxaliplatin (Eloxatin®), and fluoropyrimidine. After discontinuation of study treatment, patients will receive care as considered appropriate by the investigator. Patients will continue to be followed for disease progression, subsequent anticancer therapy, and survival.

Introduction: S-1 is promising drug which could replace 5-fluorouracil plus l-leucovorin (5-FU/l-LV) in treatment of advanced colorectal cancer. Phase I/II study of S-1 plus Oxaliplatin (SOX) demonstrated its promising activity with acceptable toxicity as first-line chemotherapy in patients with untreated metastatic colorectal cancer and S-1 showed equivalent possibility to 5-FU/l-LV. On the other hand, phase I/II study of S-1 plus oral Leucovorin (S-1/LV) demonstrated that this regimen had enhanced efficacy in comparison with S-1 alone. From these results, it was expected that S-1/LV plus Oxaliplatin (SOL) would be more effective than SOX. Therefore, phase I/II study of SOL combination therapy was planned. Purpose A dose-finding study of S-1/LV plus Oxaliplatin (SOL) was planned to determine the recommended dose (RD), and to assess the response rate (RR) in patients with untreated metastatic colorectal cancer. The primary endpoints of the phase I portion are determination of the RD of SOL, and safety. The phase II portion of this study was aimed to assess the RR of SOL.

FOLFOX4 plus Avastin has been suggested as firstline regimen for advanced colorectal cancer by NCCN, a new angiogenesis inhibitor, known as Endostar(Recombinant Human Endostatin), prolonged the overall survival, time to progression and improved response rate in metastatic lung cancer in a large phase III clinical trial in china, so we design this trial to evaluate the safty and efficacy of FolFox4 plus Endostar in patients with advanced colorectal cancer

The purpose of this study is to evaluate the Progression-Free Survival (PFS) time of Sorafenib in combination with FOLFIRI regimen used as in the second front treatment in patients with advanced CRC after failure of oxaliplatin treatment.

This is a clinical trial investigating the effectiveness and safety of the combination of the study drugs cetuximab and erlotinib in patients with advanced (metastatic) refractory colorectal (bowel) cancer. If bowel cancer has spread to other organs (metastatic colorectal cancer), it is usually incurable and life-expectancy without treatment is less then 6 months on average. Currently, chemotherapy has been shown to have a significant impact in advanced colorectal cancer in terms of maintenance of quality of life and extension of survival. However, ultimately tumours will develop resistance to chemotherapy. Treatment options and subsequent survival at that stage are very limited. Therefore, new therapeutic approaches are urgently needed. It is common for colorectal cancer cells to contain growth receptors, like antennae, on their surface which regulate their growth. The drugs used in this trial have been shown to be effective in targeting one of these growth receptors; the epidermal growth factor receptor (EGFR). Cetuximab is an antibody (protein produced by the immune system involved in the defense of the body against infections) against EGFR. Cetuximab has been shown to improve the survival of patients with chemotherapy refractory advanced colorectal cancer. Erlotinib is a protein that prevents activation and hence signaling by EGFR. Erlotinib improves survival in patients with advanced lung cancer. Although, each of these drugs are known to be effective at inhibiting EGFR when they are given alone, at least in some cases, it is hoped that using two drugs that target the same receptor pathway in different ways will provide a more effective treatment. 50 patients from four hospitals in Australia will participate in this trial, with approximately 25 patients being enrolled at Austin Health. All participants will receive the same treatment. Neither of the study drugs are chemotherapy, and hence it is expected that the treatment would be well tolerated. The most frequent side effect associated with EGFR inhibitors is skin rash. Other possible side effects are diarrhea and low magnesium levels.

Laparoscopic surgery has been widely accepted for its minimal invasion and safety. However, whether it has the same survival benefit as the traditional open surgery in Chinese population is still unknown. So we designed this study to evaluate the 3 year disease free survival rate in the laparoscopic group versus the open surgery group.

To compare the progression-free survival time (PFS) in patients treated with 5-FU modulated with CoFactor (plus bevacizumab) to 5-FU modulated with leucovorin (plus bevacizumab) in patients with Metastatic Colorectal Cancer.

To determine the rate of response and duration of reponse following therapy with Aroplatin in subjects with advanced colorectal cancer resistant to standard therapies. Secondary objectives are to determine safety and tolerability of the Aroplatin therapy.

To determine the rate of response and the duration of the response following therapy with Aroplatinin patients with advanced solid malignancies.
