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.
NCT00075868
RATIONALE: Octreotide may be effective in preventing or controlling diarrhea in patients who are undergoing chemoradiotherapy for anal or rectal cancer. It is not yet known whether octreotide is effective in treating diarrhea. PURPOSE: This randomized phase III trial is studying octreotide in preventing or reducing diarrhea in patients who are undergoing chemoradiotherapy for anal or rectal cancer.
NCT01511653
The investigators are undertaking a multi-center, 13000 subject validation study of several biomarkers for early detection of colon cancer. There are stool based biomarkers and blood based biomarkers being validated in this study. The biomarkers will be compared with colonoscopy and with FIT (fecal immunohistochemistry) tests which are the current standards for colon cancer screening. This is an NCI-early Detection Research Network funded project. The population targeted for this study are those persons undergoing colonoscopy for screening. Prior to colonoscopy or even prepping for colonoscopy, subjects will provide blood and stool samples as well as specific data regarding their GI and general medical history and concomitant medications. If subjects are interested in participating, arrangements will be made to see them. The informed consent process will take place, blood will be obtained, data will be obtained, and the stool kit described and given to the subject to take home. Stool samples will be sent back to the University of Michigan using prepaid mailing labels.
NCT02119676
The purpose of this study was to determine if ruxolitinib, in combination with regorafenib, is safe and effective in the treatment of metastatic colorectal cancer.
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.
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).
NCT00048971
RATIONALE: Genetic testing may help predict how patients will respond to chemotherapy drugs and may help doctors plan more effective treatment with fewer side effects. PURPOSE: Genetic study to determine how genes affect the severity of diarrhea in patients with stage III colon cancer who are receiving chemotherapy.
NCT02083653
This is a Phase 2, open-label, randomized, 3-arm trial investigating the efficacy of two Sym004 doses (Arm A and Arm B) compared with a control group (Arm C) in subjects with metastatic colorectal cancer (mCRC) and acquired resistance to anti-epidermal growth factor receptor (EGFR) monoclonal antibodies (mAbs).
NCT00890305
This clinical trial will be performed in previously untreated patients with metastatic colorectal cancer. The study will evaluate the safety, tolerability and efficacy of the study drug, CT-011, in combination with FOLFOX chemotherapy (FOLFOX4 or mFOLFOX6) compared with treatment by FOLFOX alone.
NCT03706248
To compare the sensitivity and specificity estimates of Colvera with that of a commercially available CEA test for detection of recurrent disease in subjects with colorectal cancer that have documented recurrence or no evidence of recurrence by CT.
NCT00025025
RATIONALE: Screening tests may help doctors detect cancer cells early and plan more effective treatment for colorectal cancer. PURPOSE: Randomized screening trial to compare the effectiveness of fecal occult blood testing with that of DNA-based testing of stool and blood in identifying colorectal cancer.
NCT00027833
RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Tetanus toxoid may make tumor cells more sensitive to chemotherapy and vaccine therapy. PURPOSE: Randomized phase II trial to study the effectiveness of chemotherapy and vaccine therapy with or without tetanus toxoid compared with chemotherapy alone in treating patients who have metastatic colorectal cancer.
NCT01306630
This is an open-label, multi-center, dose-finding study of tivozanib administered in combination with capecitabine. During the dose-escalation portion, sequential cohorts of subjects with advanced solid tumors will be enrolled in order to establish the maximum tolerated dose (MTD). If the MTD is not reached, the recommended Phase 2 dose (RP2D) will be determined. In the expansion cohort, subjects with locally advanced or metastatic breast or colon cancer will be enrolled at MTD (or RP2D) to further evaluate safety and activity of this combination in these tumor types.
NCT00103142
RATIONALE: Vaccines made from a gene-modified virus and a person's white blood cells may make the body build an effective immune response to kill tumor cells. Biological therapies, such as Granulocyte-macrophage colony-stimulating factor (GM-CSF), may stimulate the immune system in different ways and stop tumor cells from growing. Combining different types of biological therapies may kill more tumor cells. PURPOSE: This randomized phase II trial is studying giving vaccine therapy together with dendritic cells to see how well it works compared to giving vaccine therapy together with GM-CSF in treating patients with liver or lung metastases from colorectal cancer removed by surgery.
NCT00081289
RATIONALE: Drugs used in chemotherapy work in 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. Chemoradiotherapy (combining chemotherapy with radiation therapy) before surgery may shrink the tumor so that it can be removed. Giving chemotherapy after surgery may kill any remaining tumor cells. PURPOSE: This randomized phase II trial is studying two different regimens of neoadjuvant chemoradiotherapy and adjuvant chemotherapy and comparing how well they work in treating patients who are undergoing surgical resection for locally advanced rectal cancer.
