Abstract The growing threat of antimicrobial resistant (AMR) bacterial pathogens coupled with the relative dearth of promising novel antibiotics requires the discovery and development additional medical interventions. Over the past decade bacteriophages have emerged one of the most promising new tools to combat AMR pathogens. Anecdotal clinical experiences under so-called ‘compassionate use’ regulatory pathways as well as a limited number of clinical trials have provided ample evidence of safety and early evidence of efficacy. For phages to reach their full potential it is critical that rigorous clinical trials be conducted that define their optimal use and that enable regulatory authorities to support the commercialization required to afford global access. The clinical development of phage therapeutics requires the design and execution of clinical trials that take full advantage of lessons learned from a century of antibiotic development and that use clinical investigation as a platform in which aspects of phage biology that are critical to therapeutics are more clearly elucidated. Translational research that elucidates phage biology in the context of clinical trials will promote highly relevant hypothesis-driven work in basic science laboratories and will greatly accelerate the development of the field of phage therapeutics.
