On October 27, 2019 the Global AMR R&D Hub convened currently active groups undertaking work modelling the development process for antibiotics. This small technical roundtable discussion was held in Berlin and facilitated a valuable exchange between expertise globally. The opportunity to better understand each other’s work, compare notes and discuss shared challenges was valuable as both these groups, and the Global AMR R&D Hub, progress with their work in understanding development realities and resource constraints in this field.
