Background: Fecal microbiota transplantation (FMT) is emerging as a potential treatment modality for individuals living with inflammatory bowel disease (IBD). Despite its promise, the effectiveness of FMT for treating IBD, particularly for ulcerative colitis (UC), still requires thorough clinical investigation. Notwithstanding differences in methodologies, current studies demonstrate its potential for inducing remission in UC patients. Therefore, standardized and robust randomized clinical trials (RCTs) are needed to further support its efficacy for managing UC. The aim of the second Rome Consensus Conference was to address gaps and uncertainties identified in previous research regarding FMT and to offer a robust framework for future studies applied to the treatment of UC.
Methods: Global experts in the field of clinical IBD, mucosal immunology, and microbiology (N = 48) gathered to address the need for standardized clinical trials in FMT investigation. The group focused on key issues, such as stool donation, donor selection, characterization of fecal biomass, potential administration routes, as well as the process of induction, maintenance, and endpoint readouts.
Results and conclusions: The consensus achieved during this conference established standardization of methods and protocols to enhance the current quality of research, with the aim of eventual implementation of FMT in managing UC and the ultimate goal of improving patient outcomes.
Keywords: FMT guidelines; clinical trials; fecal microbiota transplantation (FMT); ulcerative colitis (UC).
The aim of this consensus was to establish a standardized framework and to discuss critical methodological issues to enhance evidence-based quality of procedure and define the role of future fecal microbiota transplantation trials in managing patients living with ulcerative colitis.
