To explore the safety, efficacy and pharmacokinetic (PK) characteristics of triweekly cetuximab in combination with capecitabine as first-line maintenance treatment for KRAS/BRAF wild-type metastatic colorectal cancer: a single-arm, a single-center, Phase 1b trial. Meanwhile, Exploring the maximum tolerant dose or recommended II research dose of triweekly cetuximab combined with a fixed dose of capecitabine using '3+3' dose climbing Phase I experiment.
The purpose of this study is to prospectively evaluate the feasibility of SBRT for the management of synchronous oligo metastatic liver metastases from colorectal cancers.
The aim of this single-center retrospective cohort study is to explore the effect of late adaptation of an ERAS protocol in a high-volume colorectal surgical unit. The primary endpoint is the surgical outcome measured by early postoperative complications, defined by the comprehensive complications index. Secondary endpoints include amongst others LOS (length of stay), cost analysis, short-term follow-up in the ERAS group.
The goal of this clinical trial is to learn about efficacy of Vitamin E in combination with Fuquinitinib and Tirelizumab in patients with microsatellite stabilized mCRC who have failed standard therapy. The main question is to explore the survival time, safety and tolerability of the treatment. At the same time, the correlation between biomarkers (including PD-L1 expression, tumor mutation load, lymphocyte subpopulation, cytokines, TCR, intestinal microbes, and others) and the efficacy and drug resistance mechanism will be analyzed, so as to provide reference for the subsequent guidance of the screening of benefit groups.
This clinical trial is looking at a drug called atezolizumab. Atezolizumab is approved as standard of care treatment for adult patients with urothelial cancer, non-small cell lung cancer, extensive-stage breast small cell lung cancer, hepatocellular carcinoma and triple negative cancer. This means it has gone through clinical trials and been approved by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. Atezolizumab works in patients with these types of cancers which have certain changes in the cancer cells called high tumour mutational burden (TMB) or high microsatellite instability (MSI) or proven (previously diagnosed) constitutional mismatch repair deficiency (CMMRD). Investigators now wish to find out if it will be useful in treating patients with other cancer types which are also TMB/MSH-high or show CMMRD. If the results are positive, the study team will work with the NHS and the Cancer Drugs Fund to see if these drugs can be routinely accessed for patients in the future. This trial is part of a trial programme called DETERMINE. The programme will also look at other anti-cancer drugs in the same way, through matching the drug to rare cancer types or ones with specific mutations.
The main purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, immune response and preliminary anti-tumor activity of RO7515629 alone in participants with advanced or metastatic solid tumors expressing human leukocyte antigen G (HLA-G).
This is a randomized, controlled, multicenter phase Ⅲ study to evaluate the therapeutic efficacy and safety of chidamide + sintilimab + bevacizumab versus standard second-line FOLFIRI + bevacizumab therapy in subjects with advanced microsatellite stable colorectal cancer who have failed first-line oxaliplatin-containing standard therapy. The primary purpose is to compare the progression-free survival (PFS) of chidamide + sintilimab + bevacizumab versus standard second-line FOLFIRI + bevacizumab therapy for colorectal cancer, with a planned enrollment of 176 subjects with advanced microsatellite stable colorectal cancer who have failed first-line oxaliplatin-containing standard therapy.
This clinical trial is looking at a combination of drugs called vemurafenib and cobimetinib. Vemurafenib is approved as standard of care for adult patients with unresectable or metastatic melanoma. Cobimetinib is approved as standard of care in combination with vemurafenib for the treatment of adult patients with unresectable or metastatic melanoma. Cobimetinib and vemurafenib work in patients with these types of cancers which have certain changes in the cancer cells called BRAF V600 mutation-positive. Investigators now wish to find out if it will be useful in treating patients with other cancer types which are also BRAF V600 mutation-positive. If the results are positive, the study team will work with the NHS and the Cancer Drugs Fund to see if these drugs can be routinely accessed for patients in the future. This trial is part of a trial programme called DETERMINE. The programme will also look at other anti-cancer drugs in the same way, through matching the drug to rare cancer types or ones with specific mutations.
The goal of this observation study is to deliver an education program designed to increase knowledge of colorectal cancer prevention and nutrition education in minorities with Type 2 diabetes. The main questions it aims to answer are: - What factors are associated with colorectal cancer screening among patients with type 2 diabetes? - Will implementing a customized patient-centered, culturally appropriate colorectal cancer education, and nutrition education program reduce the risk for colorectal cancer among patients with type 2 diabetes? - What is the impact of a patient-centered, culturally appropriate colorectal cancer education, and nutrition education intervention program on colorectal cancer screening and dietary indices among patients with type 2 diabetes compared to outcomes with patients who do not receive the intervention (usual care)? Participants randomized to the intervention group will: - receive a customized patient-centered, culturally appropriate education program - participate in eight (8) education sessions - be given booklet with colorectal cancer education and nutrition education to use as a workbook Researchers will compare colorectal cancer knowledge, perceptions, self-care, and social norms scores and dietary indices of the intervention group to the control group immediately and 6-months post intervention to see if the education program increased colorectal cancer knowledge and screenings and changes in dietary habits.
The endocannabinoid system plays important roles in the modulation of gastrointestinal motility and secretions. These effects are mainly mediated by the activation by the endocannabinoids anandamide (AEA) and 2-arachidonylglycerol (2-AG) of CB1 receptors expressed on cholinergic neurons. Cannabis sativa extracts also perform these activities, through the detection of CB1 receptors by the phytocannabinoids they contain, in particular delta9-tetrahydrocannabinol. CB1 receptors are abundantly expressed at the synaptic terminals of excitatory motor neurons and cholinergic secretomotor neurons and their activation induces prejunctional inhibition of acetylcholine release. It is thought that the endocannabinoids AEA and 2-AG, by activating these receptors, may exert a physiological control on gastrointestinal contractility and secretions. This research hypothesizes that drugs capable of inhibiting the biosynthetic and catabolic enzymes of endocannabinoids, of inhibiting the transmembrane transport of endocannabinoids or of allosterically modulating CB1 receptors induce important regulating effects of basal contractility and excitatory motor responses, induced by activation of neurons intramural cholinergics, of colonic circular smooth muscle. The effects of drugs acting on CB receptors, endocannabinoid biosynthetic and catabolic enzymes and endocannabinoid membrane transporters on basal contractility or induced by neuronal activation of colonic preparations in vitro will be evaluated. The study will enroll patients affected by colorectal cancer to undergo elective resective surgery at any stage, undergoing upfront surgery or after neo-adjuvant therapy with a therapeutic interval greater than 6 weeks. In the selected patients (see inclusion/exclusion criteria), a fresh sample of about 2.5 cm of healthy colon (healthy resection margin) will be taken, which will be taken in the operating room and sent to the laboratory for in vitro study. Expected results: The study is expected to provide new evidence regarding the induction of pharmacological effects by allosteric receptor modulators of CB1 receptors, inhibitors of endocannabinoid biosynthetic and catabolic enzymes, and inhibitors of cannabinoid transporters in the human colon, which may open interesting perspectives regarding the development of new therapeutic strategies for the treatment of constipation, diarrhea and irritable bowel syndrome.
