First human test of lassa fever pill shows promise for safety

This early-stage study tested an experimental oral drug called ARN-75039, being developed to treat Lassa fever, a serious viral illness. The trial involved 94 healthy adults aged 18 to 55 who received either the drug or a placebo to check for side effects and how the drug moves through the body. The main goal was to see if the drug is safe and tolerable before testing it in people with Lassa fever.
