Filter by:This phase II trial studies the effect of avapritinib in treating malignant solid tumors that have a genetic change (mutation) in CKIT or PDGFRA and have spread to nearby tissue or lymph nodes (locally advanced) or other places in the body (metastatic). Avapritinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Avapritinib may help to control the growth of malignant solid tumors.
This phase II trial studies the effect of atorvastatin in treating patients with ulcerative colitis who have a dominant-negative missense P53 mutation and are at risk of developing large intestinal cancer. Patients with ulcerative colitis are known to have an increased risk of developing large intestinal cancer. Better ways to control ulcerative colitis and more knowledge about how to prevent colon cancer are needed. Atorvastatin is a drug used to lower the amount of cholesterol in the blood and to prevent stroke, heart attack, and angina (chest pain). It blocks an enzyme that helps make cholesterol in the body. It also causes an increase in the breakdown of cholesterol. The information gained from this study may help doctors learn more about atorvastatin as an agent in cancer prevention, and may help to improve public health.
Colorectal cancer (CRC) is the third most common cancer in men and the second in women with an incidence of 43,350 new cases in 2018. This incidence is increasing every year. Early detection is crucial in this pathology. In France, free screening is organized by health insurance for people aged 50 to 74 years. This screening is based on an immunological test (FIT: Fecal Immunological test), which aims to detect the presence of blood in the stool. In fact, some polyps or cancers cause bleeding that is often minimal and therefore difficult or even impossible to detect with the naked eye. If this test is positive, a colonoscopy is done to check whether or not abnormalities are present in the colon or rectum. Performed under anesthesia, this examination can detect the possible presence of polyps or cancer. Recently, with the covid-19 epidemic, the investigators were faced with an extension of the delays for colonoscopies which led to delays in patient care. To prevent this, they propose to develop a blood test that would allow rapid identification of patients with colorectal cancer, requiring rapid management. This blood test will permit to have a parameter for stratifying the therapeutic care in the event of epidemia or situation that constrains the organisation of the health system.
A phase II study to assess the efficacy and safety of Surufatinib combined with Sintilimab as a second-line treatment in patients with advanced MSS-Type CRC.
The investigators have developed an innovative mobile health (mHealth) coping skills training protocol, mCOPE, that is adapted to meet the multiple symptom needs and stage-of-life challenges faced by young and middle-aged adults with cancer, and delivered in a convenient and flexible format that does not incur further demands. Young and middle-aged colorectal cancer patients who report pain, fatigue, and psychological distress will be invited to participate in the study. Participants will be randomly assigned to one of two conditions: mCOPE or standard care. mCOPE will teach patients coping skills to manage their cancer-related symptoms (pain, fatigue and distress) in the context of unique age-related challenges; session content will be tailored based on participants' report. mCOPE sessions will be delivered via videoconferencing to the patient in his/her own environment and scheduled at times that are convenient to the patient. mHealth technology, including a mobile app, will be used to capture daily symptom and coping skills use data, allowing the study team to provide personalized real-time feedback to patients. Investigators want to understand the impact of the mCOPE intervention delivered to young and middle-aged colorectal cancer patients with pain, fatigue, and distress. mCOPE is expected to lead to reduced symptom severity and improved quality of life. Study aims include: testing the efficacy of mCOPE for improving symptoms and quality of life and examining improved self-efficacy for symptom management as a mediator of symptom severity.
To evaluate the tolerance of patients with colorectal cancer to hyperthermic intraperitoneal chemotherapy with Raltitrexed, to determine the dose limiting toxicity and maximum tolerated dose.
This study assesses the feasibility of SGM-101, a fluorochrome-labeled anti-carcinoembryonic antigen monoclonal antibody, for intraoperative near-infrared fluorescence imaging of colorectal brain metastases by injecting SGM-101 intravenously 3 - 5 days prior to surgery.
The therapeutic regimens of adjuvant and neoadjuvant chemotherapy for colorectal cancer (CRC) remain largely relied on clinical experience, and thus preclinical models are needed to guide individualized medicine. The investigators are going to establish 3D bioprinted CRC models and organoids from surgically resected tumor tissues of CRC patients with or without liver metastases. In vitro 3D models and organoids will be treated with the same chemotherapy drugs with the corresponding patients from whom the models are derived. The sensitivity of chemotherapy drugs will be tested in these two types of in vitro models, and the actual response to chemotherapy in patients will be evaluated. The predictive ability of 3D models for chemotherapy sensitivity in CRC patients will be compared with that of the organoids. This observational study will validate the potential value of 3D bioprinted tumor models in predicting the response to chemotherapy in CRC.
Evidence from randomized controlled trials shows that exercise during cancer treatment benefits physical fitness, fatigue and quality of life. Since the effect of exercise on clinical outcome is currently unknown, exercise is not included as integral part of standard cancer care. Moreover, evidence regarding the optimal exercise prescription in terms of type and dose is lacking. To maintain quality of life in patients receiving palliative treatment with chemotherapy, toxicity-induced modifications in the prescribed chemotherapy dose are common. Such modifications - occurring in 40% of patients with metastatic colorectal cancer - may reduce benefit of treatment. The investigators hypothesize that exercise prevents chemotherapy dose modifications by reducing toxicity and enhancing psychological strength. Additionally, based on studies in rodents and preliminary data in patients with cancer, the researchers hypothesize that exercise has beneficial effects on the functionality of the natural killer cells, which play an important role in the innate immune defense against cancer. Both, fewer dose modifications and improved immune function may improve progression-free survival. This study is a three-armed trial comparing resistance exercise, aerobic interval exercise and usual care in patients with metastatic colorectal cancer to select the optimal exercise prescription for preventing chemotherapy dose modifications. The trial will use a Bayesian adaptive multi-arm multi-stage design with several interim analyses after which an ineffective study arm can be dropped early. This novel design makes the trial more efficient and reduces patients' exposure to suboptimal study arms. Evidence regarding the exercise effects on i) clinical outcome, ii) the optimal exercise prescription, and iii) the underlying mechanisms, elucidates the potential of exercise to boost benefit from chemotherapy treatment. This evidence provides leads to improve progression-free survival and quality of life of patients suffering from one of the leading causes of cancer death worldwide.
A Mediterranean Diet (MedDiet), a largely plant-based dietary pattern, is relevant to CRC prevention and microbial production of anti-cancer metabolites in observational studies. A MedDiet can shift BA metabolism as shown in primates and when combined with calorie restriction, shows superior adherence and weight control in humans, given its palatability. To date, no studies have tested in an RCT the effects of a MedDiet alone (MedA), WL through lifestyle intervention (WL-A) or a calorie-restricted MedDiet for WL (WL-Med) on the BA-gut microbiome axis and its relevance to CRC prevention among AAs. A multidisciplinary team combining expertise in psychology, nutrition, microbiology, molecular cell biology, computational biology, medicine and biostatistics, proposes to conduct a four-arm RCT in which 232 obese AAs, 45-75 years old complete one of the following 6-month interventions: Med-A, weight stable; WL-A, calorie restriction with no diet pattern change; WLMed; or Control. The investigators will use samples and data collected at baseline, mid-study (month-3) and post-intervention to compare the effects of the interventions on 1) Concentration and composition of circulating and fecal BAs; 2) Gut microbiota and metabolic function; and 3) Gene expression profiles of exfoliated intestinal epithelial cells.
