Antibacterial resistance is a great concern and requires global action. A critical question is whether enough new antibacterial drugs are being discovered and developed. A review of the clinical antibacterial drug pipeline was recently published, but comprehensive information about the global preclinical pipeline is unavailable. This Review focuses on discovery and preclinical development projects and has found, as of 1 May 2019, 407 antibacterial projects from 314 institutions. The focus is on Gram-negative pathogens, particularly bacteria on the WHO priority bacteria list. The preclinical pipeline is characterized by high levels of diversity and interesting scientific concepts, with 135 projects on direct-acting small molecules that represent new classes, new targets or new mechanisms of action. There is also a strong trend towards non-traditional approaches, including diverse antivirulence approaches, microbiome-modifying strategies, and engineered phages and probiotics. The high number of pathogen-specific and adjunctive approaches is unprecedented in antibiotic history. Translational hurdles are not adequately addressed yet, especially development pathways to show clinical impact of non-traditional approaches. The innovative potential of the preclinical pipeline compared with the clinical pipeline is encouraging but fragile. Much more work, focus and funding are needed for the novel approaches to result in effective antibacterial therapies to sustainably combat antibacterial resistance.

全球临床前抗菌管线。

抗菌素耐药性是一个令人高度关注的问题,需要全球采取行动。一个关键问题是是否发现和开发了足够多的新抗菌药物。最近发表了一份临床抗菌药物管道的综述,但尚未获得有关全球临床前管道的全面信息。本次审查重点关注发现和临床前开发项目,截至 2019 年 5 月 1 日,已发现来自 314 个机构的 407 个抗菌项目。重点是革兰氏阴性病原体,特别是世界卫生组织优先细菌清单上的细菌。临床前管道的特点是高度多样性和有趣的科学概念,有 135 个关于直接作用小分子的项目,代表新类别、新目标或新作用机制。非传统方法也有很强的趋势,包括多样化的抗毒方法、微生物组修饰策略以及工程噬菌体和益生菌。大量的病原体特异性和辅助方法在抗生素历史上是前所未有的。转化障碍尚未得到充分解决,特别是显示非传统方法临床影响的开发途径。与临床管线相比,临床前管线的创新潜力令人鼓舞,但也很脆弱。需要更多的工作、重点和资金来开发新方法,以产生有效的抗菌疗法,以可持续地对抗抗菌药物耐药性。
