Filter by:This Study is in two parts, the first part is to make sure that combining a potential new treatment, cediranib (AZD2171), with a standard treatment (FOLFOX) for metastatic colorectal cancer is safe. Once this part is complete and it is decided that it is safe to continue the Study will the go on to look at the efficacy of the two drugs together. This will be done by studying two treatment options. One will be the standard treatment alone (FOLFOX) + dummy cediranib (AZD2171) tablets and the other will be the standard treatment (FOLFOX) + real cediranib (AZD2171) tablets. Using dummy tablets means the study is 'blinded' and that non-one can tell the difference between the two treatment groups. This kind of study design is done to try to avoid the chance that the results might be biased in some way. The overall aim of the second part of the study is to see if adding cediranib (AZD2171) to a standard treatment for Metastatic Colorectal Cancer (mCRC), in this case FOLFOX, gives better results. That is, it's better than giving standard treatment alone in helping to prevent progression of mCRC.
Bevacizumab, an anti-angiogenic agent, plus fluorouracil based chemotherapy is considered a new standard for the treatment of metastatic colorectal cancer. Contrast-enhanced ultrasound with gas-encapsulated microbubbles can be used to assess tumour vascularity, particularly hepatic metastases, and may become a useful tool for monitoring anti-angiogenic therapies. The aim of this prospective, multicenter, non-randomized study is to evaluate the usefulness of hepatic contrast-enhanced ultrasound to predict response to bevacizumab based chemotherapy in patient with metastatic colorectal cancer. The primary objective of this study is to compare the functional vascular changes related to bevacizumab based chemotherapy and evaluated by hepatic contrast-enhanced ultrasound with classic RECIST criteria. The secondary objectives are to do a characterization of the pharmacokinetic of bevacizumab, to explore the pharmacodynamic effects of bevacizumab on functional vascular changes of hepatic metastases evaluated by hepatic contrast-enhanced ultrasound and to analyze the possible relationships between treatment efficacy or toxicity and constitutional gene polymorphisms linked to the bevacizumab.
The purpose of this study is to assess the objective response rate (ORR) when panitumumab is administered in combination with irinotecan as 2nd-line therapy in subjects with previously treated metastatic colorectal cancer (mCRC).
The purpose of the study is to evaluate the safety and efficacy of FOLFIRI (Irinotecan, Leucovorin and 5 Fluorouracil) chemotherapy when combined with sunitinib or FOLFIRI chemotherapy without adding sunitinib as the first line treatment of patients with metastatic colorectal cancer.
Major attempt is being given to the potential of curing patients with metastatic colorectal cancer due to the recognition of dramatic change in survival figures achieved in palliative chemotherapy combination treatment protocols. Achieving resectablity rates in previously unresectable patients has been defined as study endpoint among other well known primary and secondary objectives. Curing metastatic colorectal cancer is most likely in resectable patients and therefore the logical next step after completion of chemotherapy combination studies (e.g. EORTC 40983) is the addition of targeted agents. Bevacizumab has the most valid data of improving outcome figures and was therefore chosen as additional agent. Safety of the combination with Xelox was demonstrated in the investigators pilot trial (Gruenberger JCO 2006, ASCO 2006, WCGC 2006, ESMO 2006), consequently response rate and resection rate will be the primary endpoints in this trial. STUDY OBJECTIVES Primary Objective The primary objective of this study is the Resectability (R0) rate after neoadjuvant Bevacizumab in potentially resectable mCRC. Secondary Objectives The secondary objectives of this study include - Feasibility with regards to GI bleeding and wound healing complications after surgery of liver metastases - General safety - Overall Response Rate (ORR) - Recurrence Free Survival (RFS) - Overall Survival (OS) STUDY DURATION Recruitment is planned for 12 months. Patients will be treated for 6 cycles XELOX and 5 cycles Bevacizumab. Surgery will be performed 2 weeks after the last Capecitabine administration, allowing a time window of 5 weeks between the last Bevacizumab administration and surgery. Therapy with 6 cycles of XELOX and Bevacizumab will be restarted 4-5 weeks after surgery. With a Follow up period of 2 years after the last enrolled patient, in order to assess RFS and OS, the trial will last for approx. 3 years. NUMBER OF CENTRES Four centres with a high level of experience in the surgery of liver metastases are planned to participate in this study. SELECTION CRITERIA Total Number of Patients and Target Population The planned total sample size for this study is 43 patients. Patients with potentially resectable metastatic colorectal cancer previously untreated for metastatic disease will be enrolled in this trial.
The purpose of this study is to assess a maximal tolerable dose and to assess the safety of a chemotherapy-combination of cetuximab, irinotecan, oxaliplatin and 5-fluorouracil (5-FU)/folinic acid (FA) as first-line treatment for metastatic colorectal cancer.
This is a multi-center, open-label, randomized, phase 2, two-arm clinical trial to be conducted in the United States. Approximately 210 eligible KRAS wild-type expressing metastatic colorectal cancer subjects who have failed first-line oxaliplatin-based chemotherapy (with at least 4 doses of oxaliplatin-based chemotherapy) with at least 4 doses of bevacizumab (failure is defined as toxicity due to oxaliplatin-based chemotherapy or progression of disease on first-line treatment) will be randomized in a 1:1 ratio to receive either a once-every-two-weeks (Q2W) FOLFIRI regimen plus panitumumab 6 mg/kg or a Q2W FOLFIRI regimen plus bevacizumab (either 5 mg/kg or 10 mg/kg, depending on physician choice and institutional standard of care).
Systemic chemotherapy for metastatic colon cancer is often used in the neoadjuvant setting for patients undergoing liver resection. This treatment is given either to keep the tumor at bay or reduce its size before the time of resection. While many metastatic tumors might appear to respond well and even radiographically disappear following neoadjuvant therapy, it is unclear whether grossly or radiographically negative areas of previous disease are microscopically free of tumor cells. As such, when possible, resection boarders typically follow 1 cm margins from the tumor size prior to neoadjuvant therapy. These margins might be necessary to encompass all histologically present disease or they might be unnecessarily large, serving only to increase the mortality and morbidity of the operation. This study begins to address this question by a histological examination of the pattern of cell death in areas of metastases removed after neoadjuvant therapy. Furthermore, clinical cases in which neoadjuvant therapy allowed for resection of previously unresectable cancer will be examined to determine whether there is an increased rate of recurrence despite "negative" resection boundaries in these cases.
The primary objective is to estimate the effect of the human homolog of the Kirsten rat sarcoma-2 virus oncogene (KRAS) mutation status (wild type versus mutant) from tumor tissue on efficacy endpoints in patients with metastatic colorectal cancer (mCRC) receiving second-line chemotherapy with panitumumab after failing first-line treatment.
The purpose of this study is to determine the efficacy and safety of bevacizumab/capecitabine/oxaliplatin combination in metastatic or recurrent Korean colorectal cancer.
