Rentosertib is a drug created with the assistance of AI. The AI originally indicated that the drug could help treat patients suffering from a chronic lung disease, but data from clinical trials show it could also slow the aging process. The drug reduced the biological markers of age as measured by six 'aging clocks', a different kind of AI technology designed to predict a person's morbidity and mortality. While the drug shows promise, it is still years away from regulatory approval, even for use in sick patients.
