AI-driven Narrow-band Imaging Score for Disease Assessment and Outcome Prediction in Ulcerative Colitis

This is a multicentre prospective international study. This study aims at developing a new simple endoscopic score using white light endoscopy - high definition (WLE-HD), Texture and colour enhancement imaging (TXI), red dichromatic imaging (RDI) and narrow-band imaging (NBI) modes, focusing on vascular features to distinguish between quiescent versus patchy mild Ulcerative Colitis. It will evaluate the new score's diagnostic performance in defining disease activity/remission compared to existing endoscopic and histological scores and predict long-term clinical outcomes. Finally, it also aims to develop and adapt existing artificial intelligence (AI) algorithms according to WLE-HD, TXI, RDI and NBI to grade and standardize endoscopic and histological disease assessment and predict long-term clinical outcomes. The study will be divided in several phases: - In the first phase, the score will be developed on the first 30 consecutive virtual electronic chromoendoscopy (VCE) videos (using TXI-RDI and NBI) of UC patients, with different grade of disease activity. Experts in inflammatory bowel disease (IBD) endoscopy will review images and videos from recruited patients to define the endoscopic mucosal and vascular features of the new score. These will be used for a stepwise discussion. A round table discussion using modified Delphi method will be conducted by experts worldwide to ensure equal participation and identify the best component descriptors of endoscopic vascular healing. The components that will achieve 100% consensus will be selected, and the most important endoscopy predictive variables will be confirmed by using a machine learning technique. Finally, a new endoscopic score will be generated. This should be reproducible, valid and responsive. - In the second phase, the new endoscopic scoring system will be validated in a large cohort of UC patients, focusing on patients with quiescent disease versus patchy mild colitis. Diagnostic accuracy, interobserver agreement and ability to predict clinical outcome according to the new endoscopic score focused on vascular features assessed with VCE will be evaluated - In the third phase, the reproducibility of the new endoscopic scoring system will be evaluated among gastroenterologists with different levels of experience through a short survey and a computerised training module. - In the fourth phase, new and existing AI algorithms will be developed and adapted to these endoscopic videos and histological images to grade and standardize endoscopic and histological disease assessment and predict long-term clinical outcome in UC.

VECTORS - A Study to Evaluate Transmural Healing as a Treatment Target in Crohn's Disease

PROVIDENCE - Prospective Non-interventional Study (NIS) to Examine Patient-reported Outcomes and Real-world Clinical Data in Patients With HER2-positive, HER2-low or HER2-ultralow Unresectable or Metastatic Breast Cancer Treated With Trastuzumab Deruxtecan

Eligible participants will be those patients with documented HER2-positive, HER2-low or HER2-ultralow unresectable or metastatic BC receiving T-DXd treatment in line with the applicable summary of product characteristics (SmPC) within routine clinical practice. All diagnostic and treatment procedures including visit frequency are at the discretion of the treating physician and not defined by the protocol. T-DXd treatment is considered as a selection criteria. Patients will be informed about use of digital healthcare application (DiGA). Approximately 800 eligible participants will be enrolled which includes 400 patients in the HER2-positive cohort and 400 patients in the HER2-low/ HER2-ultralow cohort.

A Non-interventional, Prospective Study With Benralizumab

This is a prospective observational study to investigate the asthma control and health realted quality of life (HRQL) of benralizumab treated patients in routine clinical practice, their asthma medication intake, and their changes in asthma medication during the study, up to 52 weeks. The asthma control will be analyzed by using the Asthma Control Test (ACT) and the Asthma Impairment and Risk Questionnaire (AIRQ®) at different timepoints during the study period either collected by the investigator or self-reported by the patient. In addition, health realted quality of life will be assessed at baseline and routine follow-up visits using the mini Asthma Quality of Life Questionnaire (miniAQLQ) which is collected by the investigator. To investigate the medication intake and assess the changes in asthma medication, the patients will record their weekly medication intake in a paper-based or an electronic medication diary throughout the study.
