Abstract (original English)

Introduction This study provides an overview of the development of the first drug authorized for use in cell therapy. Areas covered We analyze the case of darvadstrocel, an example of a successful cell-therapy drug used worldwide to treat Crohn's perianal fistula. A bibliographic-historical analysis of the first cellular treatment approved by the EMA, including relevant aspects concerning the authors, who were involved in the whole process. We would like to highlight the following messages: Development: The article describes the development process of the drug, from initial concept through the clinical trial phases. Learning from failure: In describing the development of darvadstrocel, the authors highlight the importance of learning from failures, which is crucial to achieving successful outcomes. Collaboration: The article underscores the need for collaboration between public and private institutions to facilitate the advancement of cell-therapy drugs and ensure efficiency while adhering to regulatory guidelines. Expert opinion Regulatory requirements play a crucial role in the design and development of advanced therapies such as cell-therapy drugs. The findings of this study underscore the significance of appropriate disease application, meticulous donor selection, robust manufacturing processes, and proper therapy administration. Only by adopting these measures can cell-the
