NCT00642603
This 2-arm study was designed to evaluate the efficacy and safety of 2 treatment regimens of Xeloda and Avastin, with either irinotecan or oxaliplatin administered for the first 12 cycles, as first line treatment in patients with metastatic colorectal cancer. Patients were randomized to receive 2-weekly cycles of treatment with either: 1) Xeloda, Avastin and oxaliplatin; or 2) Xeloda, Avastin and irinotecan. After 9 cycles, patients continued to receive maintenance treatment with Xeloda + Avastin. The anticipated time on study treatment was until disease progression, and the target sample size was 100-500 individuals.
NCT00816777
The primary objective of this study is to evaluate the safety and efficacy of Irinotecan Bead in combination with intravenous chemotherapy versus intravenous chemotherapy alone in the treatment of unresectable liver metastases in patients with colorectal cancer. The results of this study are intended to be used in support of a PMA application for a combination device
NCT00559013
Purpose of the study is to assess the utility of PSD Veritas as a staple line reinforcement to minimize the risk of leakage during or after colo-rectal surgery.
NCT00068692
This randomized phase III trial is comparing the effectiveness of three adjuvant combination chemotherapy regimens in treating patients who are receiving radiation therapy and fluorouracil either before or after surgery for stage II or stage III rectal cancer. Drugs used in chemotherapy, such as irinotecan, fluorouracil, leucovorin, and oxaliplatin, use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known which adjuvant combination chemotherapy regimen is more effective in treating patients who are receiving radiation therapy and fluorouracil either before or after surgery for rectal cancer.
NCT01340300
Metformin is a medication that is commonly used in the treatment of diabetes. Recently small studies in cancer patients without diabetes suggest that metformin may benefit in lowering insulin levels. In those studies of patients with cancer but not diabetes, glucose (or sugar) levels in the blood are generally no lowered. Insulin and insulin-like growth factors affect the growth of cancer cells. This randomized study will compare different interventions; exercise, exercise and metformin, metformin alone, or a control arm. The investigators are not directly testing how either exercise or metformin affects your disease. The investigators are testing how they affect insulin levels in your body as well as other blood markers. The investigators believe that these blood tests may either be related to cancer recurrences or be an early sign of cancer recurrences and they are testing how both exercise and metformin may change those markers.
NCT01917513
The purpose of this study is to compare the adenoma detection rate of G-EYE™ high definition colonoscopy with that of standard high definition colonoscopy
NCT00911170
This is a phase 3, randomized, double-blind, placebo-controlled multi-center study evaluating the efficacy of pegfilgrastim to reduce the incidence of febrile neutropenia (FN) in patients with newly diagnosed, locally-advanced or metastatic colorectal cancer receiving first-line treatment with bevacizumab and either 5-fluorouracil, Oxaliplatin, Leucovorin (FOLFOX) or 5-fluorouracil, Irinotecan, Leucovorin (FOLFIRI). This study will also investigate the effect of adding pegfilgrastim to bevacizumab and either FOLFOX or FOLFIRI by evaluating overall survival, progression-free survival, and overall response rate in each arm at regular intervals over a maximum of 60 months follow-up.
NCT00417040
This pilot clinical trial studies how well using the internet to collect symptoms and the ability to carry out daily activities works in patients with enrolled on Cancer and Leukemia Group B (CALGB) studies. A study that evaluates a patient's ability to use a clinic waiting room computer to report their symptoms and their ability to carry out daily activities may help doctors understand a patient's use of a computer to report symptoms.
NCT00883792
Colorectal cancer (CRC) is a major burden in western countries. The disease develops from precursor lesions during a long time-interval. Colonoscopy can detect and remove CRC precursor lesions and may thus be effective for CRC prevention. Many national and international health organisations demand evidence from randomised trials to reduce incidence or mortality of the target disease before advocating population-wide cancer screening. However, while colonoscopy screening for the prevention of colorectal cancer is established in the United States and several European countries, no randomised trials exist to quantify the possible benefit of colonoscopy screening. NordICC is a randomised trial investigating the effect of colonoscopy on CRC incidence and mortality. NordICC is a multicentre, randomised trial in Nordic countries, the Netherlands and Poland. A minimum of 66 000 individuals, age 55-64 years, are drawn randomly from the population registries in the participating countries. 22 000 are invited for once-only colonoscopy (2:1 randomisation). Expected work-load with 50% compliance will be 11,000 colonoscopies. At the screening examination, all detected lesions are biopsied and removed whenever possible. The remaining 44 000 individuals (control group) are not offered any screening examination (care as usual).The primary study aims are CRC incidence and CRC mortality after 15 years of follow-up, with an interim analysis after 10 years of follow-up. In an intention-to-treat approach, a risk reduction of CRC mortality of 25% in the colonoscopy screening group compared to the control group is expected after 10 years follow-up, estimating 50% compliance in the screening group.
NCT00842257
The purpose of this research study is to learn whether panitumumab helps treat colorectal cancer in participants who have not responded to treatment with cetuximab. Panitumumab is a human monoclonal antibody. Antibodies are proteins that recognize a foreign substance in the body and then attach themselves to it making it exposed to destruction. Panitumumab attaches itself to a protein on cancer cells called "epidermal growth factor receptor" or EGFR. EGFR helps cancer cells to grow, and blocking EGFR helps prevent cancer cells from growing.
NCT01819766
This study aims to determine the performance of the Exact IBD-ACRN surveillance test to detect colorectal cancer (CRC) and colorectal neoplasia in patients with inflammatory bowel disease (IBD). Patients with an IBD diagnosis for at least eight years or diagnosis of primary sclerosing cholangitis (PSC) and who are eligible for CRC screening are eligible to participate in this study. Enrolled subjects will collect a stool sample for the Exact IBD-ACRN surveillance test. Subjects must have undergone colonoscopy no more than 90 days prior to enrollment and will undergo colonoscopy or surgical intervention within 120 days of enrollment. Tissue diagnosis of CRC will be established by histopathologic examination.
NCT00069095
This 4 arm study assessed the efficacy and safety of oral capecitabine (Xeloda) or intravenous (iv) fluorouracil/leucovorin, in combination with iv oxaliplatin (Eloxatin) with or without iv bevacizumab (Avastin), as a first-line treatment in patients with metastatic colorectal cancer. Patients were randomized to receive 1) XELOX (Xeloda 1000 mg/m\^2 orally \[po\] twice a day \[bid\] on Days 1-15 + oxaliplatin in 3 week cycles), 2) FOLFOX-4 (oxaliplatin + leucovorin + fluorouracil \[5-FU\] in 2 week cycles), 3) XELOX + bevacizumab (7.5 mg iv on Day 1 in 3 week cycles), or 4) FOLFOX-4 + bevacizumab (5 mg iv on Day 1 in 2 week cycles).
NCT00588900
RATIONALE: Drugs used in chemotherapy, such as irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Cediranib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving irinotecan together with cediranib may kill more tumor cells. PURPOSE: This phase II clinical trial is studying how well giving irinotecan together with cediranib works in treating patients with metastatic colorectal cancer that did not respond to previous oxaliplatin, fluoropyrimidine, and bevacizumab.
NCT00153816
Extensive experimental and observational data suggest that intake of calcium and of vitamin D exert protective effects on colorectal neoplasia. Building on their previous work, the investigators will investigate the chemopreventive effect of vitamin D in the large bowel, to study whether calcium with vitamin D is more effective than calcium alone, and to confirm their positive finding regarding calcium. The goal of this study is the development of chemopreventive combinations that will reduce risk of colorectal neoplasia sufficiently to permit the lengthening of surveillance intervals in most patients and to clarify important issues regarding the mechanisms of colorectal carcinogenesis and chemoprevention.
NCT00032344
Colorectal cancer is a leading cause of cancer death in the United States. Mortality remains high because most colorectal cancers are detected after there has been regional or distant spread, precluding curative surgical resection. With this in mind, screening strategies have been recommended for asymptomatic individuals which hope to reduce mortality from colon cancer by detecting and removing premalignant adenomatous polyps or early malignant lesions. Screening of asymptomatic individuals over age 50 with sigmoidoscopy and fecal occult blood tests has been advocated by the American Cancer Society. However, current screening will identify only 50% of patients who have adenomatous polyps. More sensitive tests for polyp detection, like colonoscopy, are costly, require extensive resources and are unlikely to be used for screening large populations. Ideal screening would identify patients with the highest risk of cancer and target more sensitive screening tests at this population. The identification of low cost, easily collectible risk factors which can be used to target patients for the more sensitive screening tests is the primary purpose of this study. Since a major segment of the veteran population is over the age of 50, there will be a substantial impact in reduction of both mortality and morbidity due to colon cancer and attendant cost savings to the VA for treatment if such risk factors can be identified. Phase I is a cross-sectional study designed to identify risk factors for large (\>1 cm) adenomatous polyps. Approximately 3200 asymptomatic subjects (age 50-75) have completed risk factor assessment, medical and dietary histories, and have undergone complete colonoscopy examination. This will identify for comparison purposes a polyp-free control group and is the first large prospective study to include such a group. Data at colonoscopy will characterize the prevalence, size and distribution of adenomatous polyps. This will permit an assessment of sensitivity of sigmoidoscopy in this population. In addition, tissue from normal rectal mucosa will be analyzed for evidence of cell proliferation activity. The primary focus of Phase I is a risk factor analysis. A multivariate analysis will be performed to determine the relationship of historical and environmental factors as well as cell proliferation activity with the presence of adenomatous polyps. A cohort consisting of a subgroup of polyp patients (large and small) and matched polyp-free controls will be tracked longitudinally to determine polyp occurrence/recurrence rates. Phase II of the study is a long-term follow-up study designed to evaluate the relative risk of two repeat colonoscopies. Phase III is an extension in follow-up of an additional five years, a total of ten years in all, to include all study patients. The primary focus will be on documenting long-term mortality and medical outcomes as well as occurrence/reoccurrence of neoplasia with special emphasis on ten-year cancer rates.
