Could a clotting protein be the first treatment for bleeding stroke?
NCT ID NCT07227246
First seen Jun 26, 2026 · Last updated Aug 21, 2026 · Updated 3 times
Summary
This Phase 3 trial tests whether a clotting drug called recombinant factor VIIa can improve outcomes for people having a hemorrhagic stroke (bleeding in the brain). The drug is given within 2 hours of stroke onset. The study will enroll 350 adults aged 18-80. Half get the drug, half get a placebo, plus standard care. The goal is to see if the drug reduces bleeding and leads to better recovery at 90 days.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Recombinant factor VIIa (a clotting protein)
- What this could lead to
- If successful, this could become the first approved treatment for acute hemorrhagic stroke, potentially reducing disability and death.
- What could go wrong
- This is an early-stage Phase 3 trial with 350 participants. The drug may not improve outcomes or could cause clotting complications. Results may not apply to all stroke patients.

Inclusion Criteria: 1. Patients aged 18-80 years, inclusive 2. Patients with spontaneous ICH 3. Able to treat with study medication (rFVIIa/placebo) within 120 minutes of stroke onset or last known well with a positive spot sign on pretreatment CT angiography or treatment within 90 minutes with or without spot sign. 4. Efforts to obtain informed consent per EFIC guidelines (U.S.) or adherence to country-specific emergency research informed consent regulations (Canada, Germany, Spain, Finland, U.K., Japan, Australia) Exclusion Criteria: 1. Score of 3 to 7 on the Glasgow Coma Scale 2. Secondary ICH related to known causes (e.g., trauma, aneurysm, arteriovenous malformation (AVM), oral anticoagulant use (vitamin K antagonists or novel oral anticoagulants) within the past 7 days, coagulopathy, etc.) 3. ICH volume \< 2 cc or ≥ 60 cc 4. Blood filling 2/3 or more of one lateral ventricle of the brain, OR, blood filling at least 1/3 of both lateral ventricles. 5. Pre-existing disability (mRS \> 2) 6. Symptomatic thrombotic or vaso-occlusive disease in past 90 days (e.g., cerebral infarction, myocardial infarction, pulmonary embolus, deep vein thrombosis, or unstable angina) 7. Clinical or EKG evidence of ST elevation consistent with acute myocardial ischemia 8. Brainstem location of hemorrhage (patients with cerebellar hemorrhage may be enrolled) 9.

Unfractionated heparin use with abnormal PTT 12. Pro-coagulant drugs within 24 hours prior to patient enrollment into the FASTEST trial (example, tranexamic acid or aminocaproic acid) 13. Low-molecular weight heparin use within the previous 24 hours 14. Recent (within 90 days) carotid endarterectomy or coronary or cerebrovascular angioplasty or stenting 15. Advanced or terminal illness or any other condition the investigator feels would pose a significant hazard to the patient if rFVIIa were administered 16. Recent (within 30 days) participation in any investigational drug or device trial or earlier participation in any investigational drug or device trial for which the duration of effect is expected to persist until to the time of FASTEST enrollment 17. Planned withdrawal of care or comfort care measures 18. Patient known or suspected of not being able to comply with trial protocol (e.g., due to alcoholism, drug dependency, or psychological disorder) 19.
