Summary

This early-stage study tested an experimental oral drug, ARN-75039, in 94 healthy adults to see if it is safe and how the body processes it. The drug is being developed to treat Lassa fever, a serious viral illness. Participants received either the drug or a placebo, and researchers monitored for side effects and measured drug levels in the blood. The results will help decide if further testing in patients is warranted.
