This is a multicenter, randomized, parallel-group, Phase III study in at least 440 patients with advanced colorectal cancer to compare the efficacy of treatment with arfolitixorin versus Leucovorin in combination with 5-fluorouracil, oxaliplatin, and bevacizumab according to modified FOLFOX-6 until PD according to RECIST 1.1 criteria.
NCT01011478
RATIONALE: Rosuvastatin may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving rosuvastatin after surgery may kill any tumor cells that remain after surgery. It may also keep polyps from forming or colon cancer from coming back. It is not yet known whether rosuvastatin is more effective than a placebo in treating colon cancer that was removed by surgery. PURPOSE: This randomized phase III trial is studying rosuvastatin to see how well it works compared with placebo in treating patients with stage I or stage II colon cancer that was removed by surgery.
NCT03602079
Open-label, Phase I-II, first-in-human (FIH) study for A166 monotherapy in HER2-expressing or amplified patients who progressed on or did not respond to available standard therapies. Patients must have documented HER2 expression or amplification. The patient must have exhausted available standard therapies. Patients will receive study drug as a single IV infusion. Cycles will continue until disease progression or unacceptable toxicity.
NCT01099449
RATIONALE: Chemoprotective drugs, such as calcium gluconate and magnesium sulfate, may prevent neurotoxicity caused by oxaliplatin. It is not yet known which administration schedule of calcium gluconate and magnesium sulfate is more effective in preventing neurotoxicity. PURPOSE: This randomized phase III trial is studying different administration schedules of calcium gluconate and magnesium sulfate and comparing how well they work in neurotoxicity in patients with colon cancer or rectal cancer receiving oxaliplatin-based combination chemotherapy.
NCT00006366
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known which regimen of radiation therapy plus chemotherapy is more effective for rectal cancer. PURPOSE: Randomized phase II trial to compare two regimens of radiation therapy plus chemotherapy followed by surgery in treating patients who have locally advanced cancer of the rectum.
NCT01183780
The purpose of this study is to compare overall survival in participants with metastatic colorectal cancer treated with either ramucirumab and FOLFIRI or placebo and FOLFIRI.
NCT04126733
The purpose of this study is to learn if combination of the two drugs regorafenib and nivolumab is an effective treatment for pMMR - MSS colorectal cancer, a special type of cancer of the colon or rectum (pMMR stands for proficient Mismatch Repair; MSS stands for Microsatellite Stable) and whether it is safe for patients. Regorafenib works by blocking several different proteins involved in tumor growth. Nivolumab is an immunotherapy drug encouraging the body's own immune system to attack cancer cells. Both drugs have been approved, but not for how they are being used as combination therapy in this study. Brand name of regorafenib is Stivarga; brand name of nivolumab is Opdivo.
NCT01298570
This randomized (2:1), multi-center, placebo-controlled, phase II efficacy study is designed to compare PFS between regorafenib + FOLFIRI chemotherapy (ARM A) versus placebo + FOLFIRI (ARM B) in patients with mCRC previously treated with a FOLFOX regimen.
NCT04144751
The primary objective of this sub-study, 2019-01B, is to collect blood specimens for research use in the development and validation of a blood-based test for colorectal cancer (CRC).
NCT04144738
The primary objective of this study is to assess the sensitivity for colorectal cancer (CRC) and specificity of the mt-sDNA 2.0 test.
NCT02890069
The purpose of this study was to combine the PDR001 checkpoint inhibitor with several agents with immunomodulatory activity to identify the doses and schedule for combination therapy and to preliminarily assess the safety, tolerability, pharmacological and clinical activity of these combinations.
NCT03531632
The primary goal of this study is to characterize the safety, tolerability, and maximum tolerated dose (MTD) of MGD007 when combined with MGA012. Pharmacokinetics (PK), immunogenicity, pharmacodynamics (PD), and the anti-tumor activity of the combination of MGD007 and MGA012 will also be assessed.
NCT03261947
The purpose of this study is to confirm the safety and tolerability of TAK-931 in a cohort of Western participants with metastatic solid tumors and to evaluate the anti-tumor activity of TAK-931 in participants with metastatic pancreatic cancer, colorectal cancer (CRC), squamous esophageal cancer (sqEC), and squamous non-small-cell lung cancer (sqNSCLC).
NCT00040599
The purpose of this trial is to determine the safety of 90Y-hMN14 at different dose levels in the treatment of colorectal 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.
NCT02703571
Phase Ib dose escalation in advanced solid tumors to identify dose for Phase II dose expansion in advanced or metastatic pancreatic cancer and KRAS-mutant colorectal cancer. Open-label, nonrandomized.
NCT01793805
This is a study to collect and analyze tissue specimens from metastatic colorectal cancer (mCRC) patients for the development of a molecularly profiled tissue repository for the primary purpose of maintaining a patient registry for future clinical trials based on the molecular profile of the tumors. The main purpose of testing these tissue specimens is to identify genetic alterations or biomarkers associated with colorectal cancer such that if new agent(s) become available, particularly those that target these genetic alterations/biomarkers, participants may be offered the opportunity to take part in a National Surgical Adjuvant Breast and Bowel Project (NSABP) treatment protocol.
NCT03457896
This is a phase II trial to examine the efficacy of neratinib plus trastuzumab or neratinib plus cetuximab in patients with "quadruple wild-type" (all RAS/NRAS/BRAF/PIK3CA wild-type), metastatic colorectal cancer based on HER2 status (amplified, non-amplified \[wild-type\] or mutated). Patients must have confirmed quadruple wild-type (WT) genotype, via NSABP MPR-1 or from colonic biopsy or a metastatic biopsy taken prior to treatment, and known HER2 status.
NCT00004860
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of fluorouracil-uracil and leucovorin in treating elderly patients who have metastatic colorectal cancer.
NCT03028831
Alaska native people (AN) have the highest recorded incidence and death rate from colon cancer in the world (\>90:100,000). We hypothesize that the AN, despite their high consumption of anti-inflammatory and antineoplastic n-3 fish oils, are at increased risk of colon cancer because of colonic butyrate deficiency resulting from their remarkably low consumption of fiber-containing foods. We hypothesize that fiber supplementation of their usual diet will result in a bloom of butyrate producing microbes in the colon, resulting in increased butyrate production, which will suppress their high microbial secondary bile acid production, antagonize the actions of other food (smoked fish) and environmental carcinogens (tobacco, alcohol), and interact with the high circulating levels of n-3 fish oils to suppress colonic inflammation and cancer risk. In order to investigate this, we will conduct a randomized double-blinded 4-week clinical trial in up to 100 randomizable healthy, middle-aged AN undergoing screening colonoscopy, with the objective of obtaining 60 completed interventions. The interventions will consist of either a high-dose soluble fiber supplement given as a drink, together with their usual diet which currently contains about 15g total fiber/d, or to a control digestible starch drink plus their usual diet. The primary endpoint will be a clinically significant reduction in Ki67 proliferative colonic mucosal biomarkers of cancer risk. Microbiome and metabolome mechanisms responsible for the anticipated changes in mucosal biomarkers will also be investigated. Our results in extreme risk AN will be further evaluated by comparison to similar measurements previously made in minimal risk rural Africans and intermediate risk African Americans. Our results will be used to provide the scientific basis for a definitive large-scale high-fiber supplementation study (to achieve \>50g total fiber/d) to suppress adenomatous polyp recurrence following colonoscopy.
