2021 Antibacterial agents in clinical and preclinical development: an overview and analysis

The World Health Organization’s (WHO) “2021 Antibacterial agents in clinical development and preclinical: an overview and analysis” report evaluates the pipelines of antibacterial candidates in different stages of development.

This report presents an analysis of antibacterial agents in preclinical (third annual review) and clinical (fifth annual review) development. The analysis covers traditional (direct-acting small molecules) and non-traditional antibacterial agents in development worldwide. It evaluates to what extent the present pipeline addresses infections caused by WHO Priority Pathogens, Mycobacterium tuberculosis and Clostridioides difficile. The report also provides an assessment of the traditional agents with respect to whether they meet a set of predefined criteria for innovation, namely absence of known cross-resistance, new target, mode of action and/or class. It also includes an overview of the agents that obtained authorization since 1 July 2017.
