Deliverable D.4.7 "Information collation - Report on collation of existing information and links on where to seek information and guidance" describes the methodology and tools used for collecting and selecting information regarding gene and cell therapy development. It focuses on how the information is collated rather than summarising the collated information itself. The published and subsequent output of the methodological reporting in this early-project deliverable is presented in D4.2. The collated information is presented in the EuroGCT website Research Pathways section (https://www.eurogct.org/research-pathways) as a searchable and filterable database. New content developed by the EuroGCT project and signposting to additional collated resources is now continually incorporated into this database, and this will continue throughout the duration of the project. The overall objective of WP4 is to develop an information hub for the research and regulatory communities, facilitating their access to high-quality information on the practical steps needed for cell and gene-based therapy development at each stage of the product development process. This deliverable, on the means of information-gathering, constitutes the foundation of all information provision by WP4. It forms the basis of all deliverables within WP4, from past deliverables (D4.4 Regulator Engagement Strategy, D4.8 Initial Landscape Mapping, and D4.9 Initial Information on Practical Steps) to deliverables due now (D4.1 Landscape Mapping, and D4.2 Resources on Practical Steps), and future deliverables (D4.3 Searchable Map, D4.5 Knowledge Sharing Function, and D4.6 Hub for the Research and Regulatory Communities). How the information is collated feeds into what information is selected, information quality and whether it meets the needs of the stakeholders. It therefore affects every output from WP4. For this reason, it is of fundamental importance to report on the details of the approaches we have taken. The field of gene and cell therapy is rapidly advancing, and so is the relevant scientific and legal information. The EuroGCT WP4 has been and will continue to review and update our methodology for collecting this information throughout the project span. Updates within the current reporting period have been reflected in this report within relevant sections and annexes.
