Resources to support antimicrobial research and development are available across a wide range of organisations’ websites and platforms. This directory brings together selected publicly available resources in one place, organised by theme, to help innovators navigate the key considerations involved in progressing an antimicrobial therapeutic from early concept through development. The resources address the practical and strategic considerations needed to progress an idea towards a viable product, from understanding clinical need and generating robust preclinical data to planning clinical translation and navigating regulatory and manufacturing requirements. The directory will continue to evolve, with additional PACE resources and relevant external materials added over time.
