A decade of advances in human gut microbiome-derived biotherapeutics
摘要
Microbiome science has evolved rapidly in the past decade, with high-profile publications suggesting that the gut microbiome is a causal determinant of human health. This has led to the emergence of microbiome-focused biotechnology companies and pharmaceutical company investment in the research and development of gut-derived therapeutics. Despite the early promise of this field, the first generation of microbiome-derived therapeutics (faecal microbiota products) have only recently been approved for clinical use. Next-generation therapies based on readily culturable and as-yet-unculturable colonic bacterial species (with the latter estimated to comprise 63% of all detected species) have not yet progressed to pivotal phase 3 trials. This reflects the many challenges involved in developing a new class of drugs in an evolving field. Here we discuss the evolution of the live biotherapeutics field over the past decade, from the development of first-generation products to the emergence of rationally designed second- and third-generation live biotherapeutics. Finally, we present our outlook for the future of this field.
