Of all the areas of drug development that artificial intelligence has the potential to transform, antibiotics may be the most consequential.
Existing antibiotics are failing, and it has been decades since a truly novel class of antibiotics was developed and brought to market. Antibiotic-resistant infections now contribute to 4.9 million deaths globally each year, and a recent World Health Organization review found that 1 in 6 lab-confirmed bacterial infections shows some degree of resistance. These hard-to-treat infections translate into longer hospital stays, higher mortality, and riskier medical procedures.
Yet a look at the current antibiotic pipeline inspires little confidence that we’re making headway against this threat. Too few new drugs are in development, particularly for the most dangerous pathogens. Only 11 antibiotics in the pipeline target the most critical bacterial threats, and even those represent limited novelty. As the WHO recently concluded, “innovation is badly lacking” in the pipeline.
Enter artificial intelligence. AI is accelerating antimicrobial discovery and opening up frontiers that would have been inconceivable just a decade ago, such as screening millions of molecules in silico in days rather than years, identifying antibiotic candidates hidden in ancient woolly mammoth genomes, and designing entirely new compounds from first principles. AI has the potential to help create new classes of antibiotics that hit new targets.
But there is a catch. The antibiotic market does not reward innovation — it often punishes it. As a result, very few investors are willing to finance R&D, especially the mid- to late-stages of antibiotic development, where costs and risks soar.
