Digestive System Diseases

Over the last decade, the use of mini-organ or organoids has been increasingly developed in fundamental research. Indeed, digestive organoids represent an essential advance compared to classical culture systems (epithelial cell lines, immortalized cells) since they preserve in culture the functional complexity present in vivo (architecture, different cell types). They also have the advantage of being able to be propagated indefinitely (unlike explants), minimizing the use of animal models and reducing the amount of tissue required. Finally, their growth and development depends on the origin of the sample (the organoid will develop differently if the cell source comes from a patient suffering from an inflammatory bowel disease, for example), thus generating models of human pathologies to better determine their physiopathology. The use of organoids in biomedical research has proven to be an indispensable tool for the understanding of cellular and molecular mechanisms involved in epithelial renewal and the screening of molecules and ingredients for applications in the health and agri-food sectors.

The purpose of this study is to evaluate the safety and performance of the Signia™ power handle, Signia™ circular adapter, and Signia™ Tri-Staple™ 2.0 circular reloads (hereafter referred to as Signia™ circular stapler) in patients undergoing left sided colon, sigmoid, or rectal resections in a post market setting.

The purpose of this study is to learn more about a new medicine called PF-08634404, and how well it works in people with cancer of the colon or rectum (CRC)). The goal is to understand if the new study medicine, combined with chemotherapy that is approved for colorectal cancer, can help people whose cancer has spread or returned after treatments taken before. To join the study, participants must meet the following conditions: * Be 18 years or older. * Have colorectal cancer that has spread to other parts of your body. * Be in good enough health to receive study treatment. * Should not be pregnant before starting treatment. Participants will be randomized (like flipping a coin) to one of 2 different treatment arms. The first arm (Arm A) will include the new medicine PF-08634404 in combination with chemotherapy that is approved for colorectal cancer, and the second arm (Arm B) will include an approved medicine for colorectal cancer, called Bevacizumab, in combination with chemotherapy that is approved for this type of cancer. Participants and their doctors will not know which arm they are being assigned to. Participants will receive all the study medications through intravenous (IV) infusions, which means the medicine is given directly into a vein. The treatment will be given in cycles, and participants may continue receiving it if it is helping and they are not experiencing serious side effects. The medicine will be given at a clinical site, where trained medical staff will check participants during and after each treatment. * The study is expected to last approximately 33 months for each participant. * Participants will have regular visits to the study site for treatment, health checks, and tests. * After stopping treatment, participants will return for a final visit about 30 to37 days later to check their health and review any side effects. * Follow-up will continue every 12 weeks by phone or in person or by reviewing health records to check on health status and any new treatments.

The primary aim of this project is to investigate how active screening and the timing of diagnosis affect the long-term health outcomes of patients with celiac disease. Additionally, the study seeks to clarify the natural course of so-called potential celiac disease. A key focus is also placed on assessing adherence to a gluten-free diet among screen-detected and, if initiated, potential celiac disease patients, their satisfaction with the diagnosis, and the diet's impact on general health and quality of life.

This is an open label, randomized, phase Ⅱ, multi-cohort study to treat subjects with ctDNA Positive Gastric and Esophagogastric Junction Adenocarcinoma. The patients will be randomized into two arms consist of Penpulimab + Anlotinib (3 weeks/cycle) + XELOX and XELOX at a ratio of 1:1. This study is conducted to assess safety and anti-tumor activity of the monoclonal antibody Penpulimab in combination with Anlotinib and standard chemotherapy as adjuvant treatment for ctDNA-positive Gastric, or Gastroesophageal Junction Carcinoma.

This study aims to pool the clinical experience of Spanish centers treating patients with 177Lu-DOTATATE to evaluate the efficacy, tolerance, and safety of the drug in routine clinical practice and to learn about the profiles of patients and tumors treated and the results in each type of patient and tumor.

This is an Open, Single Arm, Exploratory and Phase II Clinical Trial of Anlotinib Hydrochloride Capsules Combined With TQB2450 Injection in Esophageal Squamous Cell Carcinoma (ESCC) Patients as Postoperative Adjuvant Therapy. In order to observe and evaluate the efficacy and safety of Anlotinib Hydrochloride Capsules combined with TQB2450 Injection in treatment of patients with ESCC. The primary endpoint is disease free survival (DFS).
