Active clinical trials for "Colorectal Neoplasms"

A quasi-experimental non-randomized pre/post with control group trial of two models of cancer survivorship care in early-stage colorectal and breast cancer survivors cared for in a community-based, integrated health care setting.

This project aims to enhance the support for patients with breast and bowel cancer after treatment. Current follow-up care includes either self-management with patient-initiated contacts (breast cancer) or scheduled hospital visits for scans/tests for recurrence (bowel cancer). Building on extensive experience with online patient self-reporting of symptoms during treatment, the study will develop, implement and evaluate satisfaction with an improved electronic system to engage breast and bowel cancer survivors to self-report symptoms/problems online from home and get immediate tailored advice for self-management or hospital contact. The reports are displayed real-time in the hospital records alongside scans/tests to inform clinical management.

The presence of a BRAFV600E mutation is a marker of poor prognosis in patients with mCRC and associated with a median overall survival (mOS) of approximately 12 to 14 months compared to 20 to 25 months for patients with BRAF wild-type tumours. After 1st line therapy, treatment outcomes with standard therapy are poor in patients with BRAF-mutated mCRC, with response rates (ORR) of ≤ 11%, a median progression-free survival (mPFS) between 1.8 and 2.8 months, and a mOS between 4.1 and 6.2 months. Failure to achieve adequate survival outcomes with standard treatment regimens in patients with BRAF-mutated mCRC has encouraged efforts to combine multiple targeted therapies: With 665 randomized patients, the BEACON CRC trial represents the largest trial and is currently the only phase III study in patients with BRAFV600E-mutant mCRC. BERING CRC - designed as a prospective (allowing initial retrospective documentation), longitudinal, non-interventional study - will investigate the real-world effectiveness, quality of life, safety and tolerability of encorafenib and cetuximab in BRAFV600E-mutant mCRC patients, who have received prior systemic therapy. Data from this study will contribute to a deeper understanding and characterization to the everyday use of encorafenib and cetuximab in a broader patient population in the German, Austrian, and Swiss routine setting.

This proposed study is designed to investigate the specific uptake of fructose by human colorectal tumors. In this study, subjects with colorectal cancer undergoing surgery will receive an oral sugar solution containing fructose or xylose prior to surgery. The tumor will then be resected, and a portion of the tissue will be used to measure the abundance of fructose and xylose. The study hypothesis is that the tumors will take up fructose sugar but not xylose sugar. A comparison of the sugar uptake between the tumor and normal tissues from the adjacent intestinal epithelium and smooth muscle and the liver will be conducted. This proposal will confirm that human colorectal cancer tumors can directly absorb dietary sugars, which has never been demonstrated.

Unresectable metastatic colorectal cancer (mCRC) remains an incurable disease. After failure of conventional treatments involving fluoropyrimidines, oxaliplatin and irinotecan in combination or not with biotherapies targeting EGFR and VEGF; regorafenib shows a modest improvement in overall survival. Recently, trifluridine/tipiracil has also shown efficacy in phase 3 with an overall survival of around 7 months. Trifluridine/tipiracil has become the standard of care for advanced mCRC in most western countries. However, the objective response rate remains very low and the survival gain remains moderate (+2 months). Therefore, new strategies are needed to ensure that mCRC patients who have received multiple lines of therapy can receive more effective treatments. Based on previous clinical trials on IL-1 inhibition and our preclinical data, IL-1 inhibition may increase the efficacy of trifluridine/tipiracil. The goal is to test whether the addition of XB2001 to trifluridine/tipiracil could be synergistic.

The purpose of the study is to determine the feasibility of generating sufficient MicroOrganoSpheres (MOS) from a biopsy of a subject's adenocarcinoma of the colon and/or rectum that is metastatic to the liver and completing a drug screen against patient-derived MOS using standard of care drugs used in the treatment of colorectal cancer (oxaliplatin, irinotecan, 5-FU/capecitabine (Xeloda), bevacizumab, panitumumab or cetuximab, trifluridine/tipiracil (Lonsurf), regorafenib and pembrolizumab or nivolumab) in ≤ 14 days.

The overall study objective of this trial study is to identify and evaluate strategies to improve the accessibility of the video education with result dependent disclosure (VERDI) model, increasingly utilized as a pre-genetic testing (pretest) education alternative in clinical practice, to better serve a more diverse patient population at risk for hereditary cancers.

This double-blinded clinical randomized trial with a 1:1 recruitment ratio between placebo and the active group will aim to investigate the effects of intravenously administered iron in non-anemic iron deficient patients on physical capacity, immunological cells and their function prior to surgery. A total of 134 patients with colorectalcancer will be included in the study. Study outline: After initial inclusion the patient will undergo baseline testing with cardiopulmonary exercise test (CPET), then followed by an infusion of a weight dependent dosage of iron(III)isomaltoside or placebo. Then at the closest possible time to the surgery the patient will have drawn bloodwork and be re-tested by (CPET). The patient will be followed after surgery with evaluation of several outcomes including quality of recovery and complications. Further, the effects of the intervention on the patients immune function will be evaluated by two different methods: 1) by changes in neutrophil-to-lymphocyte ratio between baseline and preoperative bloodwork and 2) by evaluation mRNA expression in the tumor specimen by the Nanostring pancancer immune panel

Currently, comprehensive treatments for liver metastasis/pulmonary metastasis that cannot reach NED include systemic chemotherapy, interventional chemotherapy, molecular targeted therapy, immunotherapy, and local treatments (ablation therapy, radiation therapy, etc.) for liver metastases. Combination therapy model of local ablation, systemic chemotherapy, and anti-PD -1 monoclonal antibody hopefully can prolong patient survival. This trial will evaluate the effectiveness and safety of carrelizumab combined with microwave ablation and chemotherapy in the treatment of colorectal cancer liver metastasis/pulmonary metastasis
