Active clinical trials for "Colorectal Neoplasms"

The purpose of this study is to determine efficacy and safety of the biweekly scheme with Capecitabine and Irinotecan, plus bevacizumab in patients with metastatic colorectal cancer.

The purpose of this study is to assess the safety and clinical activity of the experimental drug EMD 525797 (study drug), a monoclonal antibody targeting alfa integrins, in combination with irinotecan and cetuximab in K-ras wildtype metastatic colorectal cancer patients.

The primary objective of this study is to compare the effect of panitumumab versus cetuximab on overall survival (OS) for chemorefractory metastatic colorectal cancer (mCRC) among patients with wild-type Kirsten rat Sarcoma-2 virus (KRAS) tumors.

Cetuximab is normally given as a weekly schedule in the therapy of patients with metastatic colorectal cancer. In order to improve the convenience for the patients in first line-therapy this study will evaluate the efficacy and safety of a bi-weekly combination of cetuximab with FOLFOX.

To determine if sorafenib when added to chemotherapy will slow disease progression more than chemotherapy alone in patients previously untreated for metastatic colorectal cancer.

To determine the depth of coagulation which is possible in human liver tissue using the saline linked RF Surface ablation with the Tissue Link floating ball. To determine the efficacy of the technique on surface liver tumors using saline linked RF surface ablati To determine a safe (non-popping upper limit) of power per area that will permit a 1 cm depth of tissue destruction without inflow occlusion an da 2 cm depth with inflow occlusion.

Background: The drug R935788 (fostamatanib disodium) is a kinase inhibitor (i.e., it interferes with cell communication and growth and may prevent tumor growth). R935788 has shown promising activity in NCI-60 (a panel of 60 diverse human cancer cell lines) against colon cancer, non-small cell lung cancer, and renal cell carcinoma cell lines, as well as in two renal cell xenograft models. This is an open-label, Phase II study of R935788. Phase I studies in patients with immune thrombocytopenic purpura, rheumatoid arthritis, and lymphoma have demonstrated safety with a continuous dosing schedule, and a maximum tolerated dose has been established. Objectives: To test an experimental drug called R935788 (fostamatinib disodium) for its ability to stop cancer growth signals, thus slowing the growth of cancer cells in laboratory testing. To determine the clinical response of R935788 administered orally twice a day on a continuous schedule in patients with colorectal carcinoma, pheochromocytoma, follicular or papillary thyroid cancer, non-small cell lung cancer, hepatocellular, carcinoma of the head and neck, and renal cell carcinoma. To evaluate the effects, safety, and biochemical response of R935788 therapy. Eligibility: Patients with colorectal carcinoma, pheochromocytoma, follicular or papillary thyroid cancer, non-small cell lung cancer (excluding squamous cell histology), hepatocellular cancer, carcinoma of the head and neck, and renal cell carcinoma whose disease has progressed after any therapy or who have no acceptable standard treatment options. Patients must have recovered from toxicities of prior therapies to at least eligibility levels. Patients who have received radiation or chemotherapy within 4 weeks of study enrollment are not eligible. Women who are pregnant or breastfeeding are not eligible. Design: Researchers will conduct the following tests and procedures during the study: Clinic visits with a physical exam, including vital signs and blood pressure, every other week during cycle 1, and once a month starting with cycle 2. Blood will be drawn weekly during cycle 1, every other week during cycle 2, and once a month starting with cycle 3; urine tests will be conducted depending on results of blood tests. Imaging tests, such as computed tomography (CT) scans (a series of x-rays) or ultrasound (an examination using sound waves), will be done every 8 weeks while the patient is receiving R935788. R935788 will be administered orally twice a day for 28 days (one cycle). Imaging studies will be obtained every two cycles. Patients will fill in a diary to show when they took the medication and to note any side effects. The 28-day treatment cycle will be repeated as long as the patient is tolerating R935788 and the cancer is either stable or getting better. Researchers will conduct the following additional tests to see how the study is affecting the patient: Other research blood samples will be collected before treatment, at cycle 1 week 3, at the beginning of cycle 2, and at 8 weeks. Optional tumor biopsies will be requested before starting treatment, at cycle 1 day 28. Patients with specific lesions or tumors may be asked for an optional tumor biopsy on day 8.

This study is designed to evaluate the mechanism(s) of resistance to the anti-epidermal growth factor receptor (EGFR) antibody panitumumab given in combination with irinotecan in metastatic colorectal carcinoma (mCRC) patients with wild-type Kirsten rat sarcoma-2 virus oncogene (KRAS) tumor status at the time of initial diagnosis.

Familial Adenomatous Polyposis (FAP) is an autosomal dominant disorder characterized by the formation of multiple adenomatous colorectal polyps usually in the teenage years. Virtually, all patients with FAP will develop colorectal cancer on average by the 5th decade of life if prophylactic surgery is not performed. Besides, these individuals must have lifelong cancer surveillance of the remaining colorectum or ileum. Use of nonsteroidal anti-inflammatory drug (NSAID), such as sulindac, or celecoxib, which selectively inhibits prostaglandin synthesis primarily via the inhibition of cyclogenase-2 (COX-2) have been shown to reduce the incidence and induce regression of adenomas in the rectum of patients with FAP. However, use of NSAIDs and COX-2 inhibitors is associated with significant comorbidity including renal and gastric toxicity and increased risk of vascular events. Therefore, identification of a chemopreventive agent that would have similar efficacy but less toxicity would enhance our ability to treat these patients. Therefore the following specific aim has been proposed:To determine in a randomized, double-blinded, placebo-controlled study the tolerability and efficacy of curcumin to regress intestinal adenomas by measuring duodenal and colorectal/ileal polyp number, and polyp size in patients with FAP.

The primary objective of this study is to evaluate PFS rate at 9 months of BIBF 1120 in combination with mFolfox6 compared with mFolfox6 combined to bevacizumab in first line patients with metastatic colorectal cancer.
