This study is for people who have had an Acute Ischemic Stroke (AIS). A stroke happens when blood flow to a part of the brain is blocked. In this study, participants will receive the usual stroke care, plus two doses of a new drug called PP-007, given through a vein in the arm. The purpose is to see if PP-007 is safe and helps improve blood flow in the brain. Participants must be 18 or older and have specific medical conditions to join.

• The study involves receiving two doses of the study drug, 24 hours apart.
• Participants must follow up with doctors for the entire study duration.
• Participants must use reliable birth control during the study and for 90 days after.

This study is important for understanding if PP-007 can help people who have had a stroke. If you are eligible and choose to participate, you will be closely monitored to ensure your safety. Discuss with your doctor if joining this study is a good choice for you.
