Dose Escalation Study of Lithium With Oxaliplatin and Capecitabine in Advanced Oesophago-Gastric or Colorectal Cancer

This study is a phase Ib, open label, multi-centre trial designed to estimate the Maximum Tolerated Dose (MTD) of lithium when combined with a standard chemotherapy regimen of oxaliplatin and capecitabine in patients with advanced, unresectable, oesophago-gastric or colorectal cancer who have received no previous treatment for advanced disease (previous adjuvant or neo-adjuvant treatment is acceptable if completed at least 6 months prior to registration). The study follows a modified Fibonacci, 3+3, dose escalation design. Patients are enrolled in cohorts of 3. All three patients in each cohort must complete at least two cycles of treatment to be evaluable for toxicity. If a patient cannot complete 2 cycles, another patient will be enrolled.

Gluteal Squeeze for Left Colon Distension

Good distension of the colon during colonoscopy is essential to detect polyps. Gas sometimes escapes the colon through the anus resulting in compromised distension. Pressure on gluteal muscles when the colonoscope tip is in the left colon might help preventing this and thus increase visibility. No previous study looked at this.

A Study of RGX-202-01 as a Single Agent and as Combination Therapy in Patients With Advanced Gastrointestinal Malignancies

RGX-202-001 is a Phase 1, first-in-human, dose escalation and expansion study of RGX-202-01 as a single agent and in combination with FOLFIRI +/- bevacizumab. RGX-202-01 is a small molecule inhibitor of the creatine transporter SLC6a8, a novel metabolic target that drives gastrointestinal cancer progression. During the dose escalation stage, multiple doses of orally administered RGX-202-01 with or without FOLFIRI +/- bevacizumab (single agent or combination therapy) will be evaluated in patients with advanced gastrointestinal tumors (i.e., locally advanced and unresectable, or metastatic) who have had PD on available standard systemic therapies or for which there are no standard systemic therapies of relevant clinical impact. In the expansion stage of the study, additional patients with colorectal cancer (CRC) selected by expression of the creatine kinase B (CKB) biomarker will be treated at the MTD (or maximum tested dose if no MTD is identified, or dose below the MTD if there is evidence suggesting a more favorable risk/benefit profile). This stage will provide further characterization of the safety, efficacy, PK, and pharmacodynamics of RGX-202-01 in combination with FOLFIRI plus bevacizumab.

Value of Butyrylcholinesterase as a Marker of Surgical Site Infection Following Surgery for Colorectal Diseases

Butyrylcholinesterase (BChE) is an ?-glycoprotein synthesized in the liver. BchE's serum level decreases in many clinical conditions such as acute and chronic liver damage, inflammation, injury and infections, and malnutrition. The Investigators prospectively evaluate patients undergoing elective procedures for colorectal diseases. Blood samples are collected preoperatively (at day 0), post-operatively in the recovery room (day 1), and on the subsequent four days (days 2, 3, 4, and 5) for assessment of BChE, C-reactive protein, and white blood cell concentrations. The same surgical team operates all patients and is blinded to the study. Patients are monitored for post-operative infection by using standard laboratory and clinical methods. If surgical site infection (SSI) is suspected the wound is swabbed and empirical antibiotics are started. The aim of the current trial is to study whether BChE is a reliable marker for the presence of SSI in patients undergoing colorectal surgery.

Ultrasound-enhanced Delivery of Chemotherapy to Patients With Liver Metastasis From Breast- and Colorectal Cancer

The aim of this clinical trial is to investigate whether the therapeutic response of chemotherapy can be improved by focused ultrasound and microbubbles. Patients with liver metastases from breast cancer and colorectal cancer will be included. Computer Tomography (CT) will be performed as a baseline scan before treatment start. Two metastases in each patients liver will be preselected and randomized to either "target lesion" to be treated or "control lesion" to serve as internal control. The patients will receive conventional treatment with chemotherapy according to national guidelines. After intravenous chemotherapy infusion the patients will receive the experimental treatment. The target lesion will get focused ultrasound (FUS). Simultaneously repeated bolus-doses of microbubbles will be administered intravenously. The investigators will measure the difference in response between FUS- treated and -untreated lesions on the post-treatment CT scan.

Self-management Support for Colorectal Cancer Survivors Colorectal Cancer Survivors: A Mixed-methods Study

Background: Survivors of colorectal cancer have to face long-term consequences of the disease and its treatment side effects, which in turn affect mood and psychological well-being. Self-management support may help colorectal cancer survivors to achieve healthy lifestyle and better adjustment. However, there is little research evidence to support it and also no theory-based self-management support interventions specifically designed for colorectal cancer survivors in Taiwan. Aim: The study aims is to test the efficacy of the Acceptance and Commitment Therapy -based self-management support program on the primary outcome, quality of life, and secondary outcomes, physical activity, fruit and vegetative intake, body mass index, sleep quality, emotion distress, and fatigue in colorectal cancer survivors . Design: An experimental design with repeated measures will be used to test the intervention efficacy. A convenient sample of 250 colorectal cancer (stage I-III) survivors who has completed initial treatments will be recruited and randomized to the control or intervention group. The intervention includes a colorectal cancer self-management information booklet, a DVD, two individual skill trainings and 12 follow-up telephone calls. These are to establish participants' self-management skills and healthy lifestyle, including physical activity and healthy eating fruits and vegetables. The control group will receive health education leaflets. Outcome variables will be assessed on the baseline, 2th, 4th, and 6th month in both groups. Descriptive analysis will be used to describe patients' demographics, disease variables, and outcome variables. The Chi-square, t-test, and General Linear Mix-effect Model will be used to test the efficacy of the study interventions.

Back-to-back Endoscopy Versus Single-pass Endoscopy and Chromoendoscopy in IBD Surveillance

The current international guidelines for CRC surveillance in IBD recommend as first choice the use of chromoendoscopy, and as an alternative high-definition white light endoscopy (HDWLE) for optimal dysplasia detection, based on data from clinical trials. However, data on the superiority of CE over HDWLE are not consistent in literature. The investigators hypothesize that the better performance of CE in some clinical trials is the result of the associated longer procedural time and the fact that every colon segment is examined twice. Currently, no studies have been published evaluating the dysplastic yield of back-to back HDWLE compared to HDWLE with a single pass or CE in patients with IBD. In the present study, the investigators aim to compare the yield of dysplasia/CRC between 1) regular HDWLE, 2) HDWLE back-to-back, and 3) CE.

A Phase I/II Study of Pexa-Vec Oncolytic Virus in Combination With Immune Checkpoint Inhibition in Refractory Colorectal Cancer

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 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 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 KRAS wild type tumor must have progressed, been intolerant of or refused cetuximab or panitumumabbased 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-PD1/PDL1 therapy. Patients must have at least one focus of metastatic disease that is amenable to pre- and ontreatment 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.

European Polyp Surveillance Trial

This protocol describes the epos (ancient greek (Επος) for "story") of a group of related clinical trials aiming at addressing one of the most important unsolved challenges in the prevention of colorectal cancer (one of our major cancer killers); the surveillance of patients with premalignant polyps in the large bowel. This project is timely because large scale colorectal cancer screening programmes are currently rolled out in most Western countries. These programmes are diagnosing large numbers of individuals with premalignant polyps (adenomas and serrated polyps). This creates both a diagnostic and resource dilemma, because the optimal surveillance strategy for these individuals to reduce future cancer risk is currently unknown.. The EPoS trials will randomize or register more than 20,000 individuals in different European countries to different surveillance colonoscopy intervals to disentangle the most effective and cost-effective surveillance strategy for the population. Subjects will be randomized according to their presenting polyp chracteristics The EPoS I trial randomizes patients with low-risk adenomas into 5 or 10-year surveillance; ; EPoS II randomizes patients with high-risk adenomas into 3 or 5-yearly surveillance ; EPoS III will include patients with serrated polyps in a one-arm study with surveillance after 5 and 10 years. The primary endpoint for all three trials is incidence of colorectal cancer after 10 years of follow-up. This EPoS trials are the largest in polyp surveillance ever conducted. They address a clinical problem affecting hundreds of thousand individuals in Europe and the US each year, it has a large size, and should thus provide definitive results.
