The potentially disastrous consequences of antimicrobial resistance (AMR) were highlighted at the recent World Economic Forum Meeting 2024. Antibiotic resistance is a rapidly growing global public health crisis that threatens the future of modern medicine and human welfare. Alarming levels of multidrug-resistant (MDR) microbes are being reported worldwide, making certain infections more difficult and sometimes impossible to treat. AMR is now the third leading cause of death around the globe. According to the World Health Organization (WHO), antibiotic-resistant bacterial infections are responsible for almost 1.3 million global deaths, while contributing to about five million deaths per year. Concerningly, no major breakthroughs have been made in the space in over 50 years. While more advanced antibiotics have been developed, the degree of innovation has been inadequate in preventing the spread of AMR, leaving the world in a highly vulnerable position.

There is a massive unmet need for the innovative development of alternative therapies with efficacy against MDRs. Traditional and next-generation antibiotics have proven incapable of alleviating the long-term threat of AMR. Resistant strains of bacteria have been documented within one year of many new antibiotic drug launches. For example, daptomycin, the standard of care for methicillin-resistant Staphylococcus aureus (MRSA) bacteremia, was approved in 2003. Strains of daptomycin-resistant MRSA emerged in 2004. More recently in 2015, ceftazidime-avibactam entered the market to treat complicated intra-abdominal infections caused by Klebsiella pneumoniae. During the same year in 2015, strains of ceftazidime-avibactam-resistant Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae (KPC-KP) were documented. This demonstrates the urgent need for non-traditional antibiotic treatment options.
