New drug could keep stents open after stroke, reducing need for rescue therapy
NCT ID NCT06813651
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.
