Filter by:Background: - Immune-based approaches in colorectal cancer have unfortunately with the notable exception of immune checkpoint inhibition in microsatellite instable (MSI-hi) disease been largely unsuccessful. The reasons for this are unclear but no doubt relate to the fact that in advanced disease colorectal cancer appears to be less immunogenic, as evidenced by the lack of infiltrating lymphocytes with advancing T stage - Pexa-Vec (JX-594) is a thymidine kinase gene-inactivated oncolytic vaccinia virus engineered for the expression of transgenes encoding human granulocyte- macrophage colony-stimulating factor (GM-CSF) and beta-galactosidase. Apart from the direct oncolytic activity, oncolytic viruses such as Pexa-Vec have been shown to mediate tumor cell death via the induction of innate and adaptive immune responses - Tremelimumab is a fully human monoclonal antibody that binds to cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) expressed on the surface of activated T lymphocytes and causes inhibition of B7-CTLA-4-mediated downregulation of T-cell activation. Durvalumab is a human monoclonal antibody directed against programmed death-ligand 1 (PD-L1). - The aim of the study is to evaluate whether the anti-tumor immunity induced by Pexa-Vec oncolytic viral therapy can be enhanced by immune checkpoint inhibition. Objective: -To determine the safety, tolerability and feasibility of Pexa-Vec oncolytic virus in combination with immune checkpoint inhibition in patients with refractory metastatic colorectal cancer. Eligibility: - Histologically confirmed metastatic colorectal cancer. - Patients must have progressed on, been intolerant of or refused prior oxaliplatin- and irinotecan-containing, fluorouracil-based, chemotherapeutic regimen and have disease that is not amenable to potentially curative resection. Patients who have a known Kirsten rat sarcoma viral oncogene homolog (KRAS) wild type tumor must have progressed, been intolerant of or refused cetuximab or panitumumab based chemotherapy. - Patients tumors must be documented to be microsatellite-stable (MSS) either by genetic analysis or immunohistochemistry OR microsatellite-high with documented disease progression following anti-programmed cell death protein 1 (PD1)/Programmed death-ligand 1 (PDL1) therapy. - Patients must have at least one focus of metastatic disease that is amenable to pre- and on-treatment biopsy. - Willingness to undergo mandatory tumor biopsy. Design: -The proposed study is Phase I/II study of Pexa-Vec oncolytic virus at two dose levels in combination with immune checkpoint inhibition in patients with metastatic colorectal cancer.
This clinical trial studies the side effects of 18F-alphavbeta6-binding-peptide and how well it works in imaging patients with primary or cancer that has spread to the breast, colorectal, lung, or pancreatic. Radiotracers, such as 18F-alphavbeta6-binding-peptide, may improve the ability to locate cancer in the body.
Single arm Phase I/II multicentric open labeled, with translational sub-study, of avelumab plus autologous dendritic cell vaccine in pre-treated mismatch repair-proficient (MSS) metastatic colorectal cancer patients..
To compare 2 different image creation/processing techniques during a standard CT scan in order to "see" problems in the liver and learn which method provides better image quality. The techniques use new artificial intelligence software to decrease image noise, which helps the radiologist to evaluate.
To estimate progression-free survival at one year in elderly patients with RAS/BRAF wild-type unresectable mCRC and good performance status treated with FOLFIRI + panitumumab as first-line therapy. The clinical hypothesis of this study is that the combination of panitumumab and FOLFIRI is a good treatment option in elderly patients with good performance status and RAS/BRAF wild-type unresectable mCRC. Another purpose of this clinical trial is to determine the RAS/BRAF mutation status in liquid biopsies at baseline and at the time of disease progression.
This randomized clinical trial studies how well a lay health worker outreach works in increasing colorectal cancer screening in Asian Americans. Training community members to educate participants about colorectal cancer and its prevention may improve colorectal cancer screening rates in Asian Americans.
The application of transarterial chemoembolisation (TACE) using LifePearl Microspheres loaded with Irinotecan in liver-only or liver-dominant metastatic disease in patients with colorectal adenocarcinoma will be observed. The registry has the following objectives: 1. map the exact indications that the device is being used for and at which stage in treatment it is being applied 2. to assess observed treatment outcomes in terms of safety and effectiveness as well as trying to determine any predictive response factors
The purpose of this study is to conduct 4 focus groups and recruit for 12 participants per focus group to explore community members' views about colorectal cancer screening (CRCS) processes and perceived benefits and impediments, what information they believe should be communicated, communication preferences (style, tone) and perceptions of screenings.
The purpose of this research study is to compare a new educational material to another widely available educational brochure. The goal is to see if the new educational material will change knowledge and behaviors about colorectal cancer and colorectal screening.
The primary aim of this study is to establish if it is possible for patients who have undergone major body surgery to complete a home based exercise training program and complete the assessments required to measure physical and cognitive function. If the investigators can establish that it is feasible to complete the training and test's then further research can follow using these methods to determine whether it is possible to improve the physical function of older patients undergoing major abdominal surgery in the period following surgery by using a simple exercise regimen that can be carried out at home. By targeting physical function in this way the investigators hope to determine if it is a method for improving frailty and well being. In turn it may also have a positive impact on health service provision.
