Summary

This study tests a new drug called TBO-309 in 78 people having a stroke caused by a blocked artery in the neck and brain. The drug is given through a vein during standard clot-removal and stenting procedures. The goal is to see if TBO-309 can keep the stent open without causing dangerous bleeding in the brain.
