Active clinical trials for "Colorectal Neoplasms"

Due to discontinuation of the Codman C3000 pump, an alternate device is necessary to continue serving patients in need of hepatic arterial infusion chemotherapy. This study aims to test the safety of hepatic artery infusion pump placement, a standard surgical procedure, and intraarterial chemotherapy initiation with the standard medication floxuridine (FUDR), using the Medtronic Synchromed II pump combined with the Codman arterial catheter in patients with unresectable (not removable by surgery) liver metastases from colorectal cancer and unresectable intrahepatic cholangiocarcinoma. This study will determine if complication and pump loss rates will be similar to previously published rates for the Codman system.

The reason for this study is to see if the study drug LY3499446 is safe and effective in participants with solid tumors with KRAS G12C mutation.

This project aims to examine the impact of different interventions designed to help individualize colorectal cancer (CRC) screening decisions in adults aged 76-85. Clinicians will be assigned by chance to one of two arms. In the Intervention arm, clinician participants will complete a training course and will also be notified of patients in the target age group who are due for a discussion about CRC screening. In the Comparator arm, clinician participants will be notified of their patients in the target age group with an upcoming visit who are due for a discussion about CRC screening. The investigators expect that patients seen by clinicians in the intervention arm will report more involvement in the decision making process, be more knowledgeable about the risks and benefits of CRC screening, and will have better quality decisions. Further, the investigators expect that the physicians in the intervention arm will have greater confidence in and demonstrate more skills for conducting shared decision making conversations as compared to those in the control arm.

This is a first-in-human, Phase 1 open-label, multicenter, dose escalation, safety, pharmacodynamic, and PK study of exoASO-STAT6 (CDK-004) in patients with advanced Hepatocellular Carcinoma (HCC) and patients with liver metastases from either primary gastric cancer or colorectal cancer (CRC).

Colorectal cancer (CRC) is one of the most common cancer worldwide. Initiation and progression of CRC involve complex interactions among genetic, epigenetic and environmental factors. Given that hereditary and familial CRC only accounts for 2% to 5% of cases, environmental factors are the key triggers of CRC. Emerging evidence has indicated that gut microbes are an important environmental factor promoting CRC development. Gut dysbiosis has been shown to promote colorectal carcinogenesis in mice. Several individual bacterial species, such as the enterotoxigenic Bacteroides fragilis (ETBF), Fusobacterium nucleatum and Peptostreptococcus anaerobius, could exert carcinogenic effects by inducing direct DNA damage, oxidative damage and activating oncogenic signaling pathways. Recent studies have shown that the appendix plays an important role in maintaining homeostasis and biodiversity of gut microbiome by providing an ideal ecological niche for commensal bacteria and production of immunoglobulin A. Considering the key role of microorganisms in gastrointestinal pathophysiology, absence of appendix may result in disruption of microbiome homeostasis, which could potentially influence the risk of developing CRC. In terms of epidemiological evidence, the association of appendectomy with the risk of CRC development has been controversial, and to date no consensus has been attained. Although gut microorganisms could be a crucial pivot between appendectomy and risk of subsequent CRC development, the direct contribution of appendectomy and the underlying mechanisms are still largely unexplored. In this study, we aim to study the association between appendectomy and colorectal cancer, and the role of appendectomy in CRC risk through causing gut microbial dysbiosis.

This is an observational study using data that has been collected from participants who received their usual treatments. Metastatic colorectal cancer (mCRC) is a cancer of the colon (large bowel) or the rectum (lowest part of the bowel just before the anus) that has spread to other parts of the body. Regorafenib is an anti-cancer drug that blocks several proteins, called enzymes, which are involved in the growth of cancer. The combination of anti-cancer drugs trifluridine and tipiracil is called TAS-102. It prevents cancer cells from growing and multiplying. Both regorafenib and TAS-102 are approved treatments for metastatic colorectal cancer and are available for doctors to prescribe to people with mCRC after previous lines of treatment have been unsuccessful. Regorafenib and TAS-102 work in different ways and impact people differently. People might receive one of these drugs first and followed by the other. The best sequence for taking these drugs is still unclear. Researchers have also found that TAS-102, when taken with another anti-cancer drug called bevacizumab, helps people live longer than when taken alone. To better understand the impact of the sequence of taking regorafenib and TAS-102 (with or without bevacizumab), more knowledge is needed about how these work together in people with mCRC in real world settings. The main purpose of this study is to learn more about the characteristics and impact of treatment in people with mCRC who received regorafenib and TAS-102 (with or without bevacizumab) one after the other. This information will be grouped based on their treatment sequence and age group (less or more than 65 years old). In addition, the researchers want to learn about : how long participants were treated with regorafenib and TAS-102 taken one after the other in a sequential order, any treatment for mCRC that the participants received after the sequential treatment, any treatment received for a condition in which the bone marrow cannot make up enough blood cells (a common side effect of cancer treatment), during the sequential treatment, if and how often white blood cells that fight infection decreased during the sequential treatment, the number of hospital or testing facility visits that participants had during the sequential treatment, and how long did participants live (also called overall survival). The participants in this study had already received regorafenib and TS-102 (with or without bevacizumab) as part of their regular care from their doctors. The data will come from the participants' information stored in an electronic health records database called Flatiron mCRC EDM. Data collected will be from January 2015 to December 2022. Researchers will only look at the health information from adults in the United States of America. In this study, only available data from routine care is collected. No visits or tests will be required as part of this study.

This is a randomized phase III study with a safety lead-in part in patients with KRAS/ NRAS and BRAF Wild Type metastatic colorectal cancer who have previously received treatment with oxaliplatin, irinotecan, fluoropyrimidines, anti-VEGF agents and anti-EGFR antibodies. The main objective of the safety lead-in part is to assess safety and tolerability of futuximab/modotuximab in combination with trifluridine/tipiracil. The primary objective of the phase III part is to compare Overall Survival of futuximab/modotuximab in combination with trifluridine/tipiracil vs trifluridine/tipiracil monotherapy in patients with tumours that are KRAS/NRAS and BRAF wild-type (WT) (Double negative [DN].

Conventional hand-stitching colostomy involves extensive hand-stitching by the surgeon. There are significant variations in the outcome of surgery due to differences in the suture techniques of surgeons. The use of a circular stapler in colostomy seems more rapid and efficient colostomy than the conventional methods.But all those reports are single center retrospective cohort study，no randomized controlled trials have been carried out so far.The aim of this study is to comparing the safety and efficiency of circular stapler-assisted colostomy with conventional hand-stitching colostomy in patients with colorectal carcinoma.

This is a randomized, multi-center phase II study of ginseng in colorectal cancer patients treated with regorafenib to determine if ginseng will reduce fatigue in this patient population and improve adherence to regorafenib. Ninety (90) subjects will be enrolled and randomized using a 2:1 allocation, with 60 subjects enrolled in the regorafenib + ginseng group and 30 enrolled in the regorafenib + no ginseng group.

The main objective of this study is to evaluate the objective response rate at two months (complete disappearance of the disease and partial disappearance of the disease) obtained after administration of combination therapy with cetuximab and irinotecan in the patients with metastatic colorectal cancer. Secondaries objectives will be assessed progression-free survival, overall survival, toxicity, quality of life.
