New stroke drug candidate passes first safety check in healthy volunteers

This early-stage study tested the safety and how the body processes a new drug called HRS-8829 in 83 healthy adults aged 18 to 55. Participants received either the drug or a placebo in increasing doses, and researchers monitored side effects and drug levels in the blood. The goal was to gather safety information, not to treat any disease, so this study does not offer direct benefit to volunteers but helps decide if further testing in stroke patients is safe.
