Brief Summary

In this 94 healthy subjects Phase I clinical trial, we assess the clinical profile of Anfibatide, a specific glycoprotein Ib antagonist. This study represents the first clinical evidence that Anfibatide exhibits strong anti-platelet effects, excellent reversibility, and low bleeding potential in healthy human subjects.
