Early clotting-factor treatment for sudden brain bleed

FVIIa for Acute hemorrhagic Stroke Administered at Earliest Time (FASTEST) Trial

NIH-funded research University of Cincinnati · NIH-11473146

This research gives a clotting medicine called rFVIIa very soon after a sudden brain bleed to see whether people with intracerebral hemorrhage do better than with standard care alone.

What this research studies

If you have a sudden intracerebral hemorrhage (a spontaneous brain bleed), this study randomly gives patients either the clotting medicine recombinant Factor VIIa (rFVIIa) plus standard care or a placebo plus standard care. Treatment must be started extremely quickly—within 120 minutes of when you were last known to be normal—with a goal that many patients receive treatment within 90 minutes using participating hospitals and mobile stroke units. The trial plans to enroll about 860 patients at roughly 100 hospital sites worldwide and is double-blind so neither patients nor clinicians know who gets the drug. Strict inclusion rules (smaller bleed volume, limited or no intraventricular bleeding, age ≤80, and GCS ≥8) are used and the study allows emergency exception from informed consent to avoid delaying treatment.

Who could benefit from this research

Good fit: Ideal candidates are adults age 80 or younger with spontaneous intracerebral hemorrhage under 60 cc, little or no intraventricular blood, a Glasgow Coma Scale score of at least 8, and who can be treated within 120 minutes of symptom onset.

Not a fit: Patients with very large hemorrhages, extensive intraventricular bleeding, severe coma (GCS <8), those treated beyond the two-hour window, or with other exclusionary conditions are unlikely to benefit and would not be eligible.

Why it matters

Potential benefit: If successful, giving rFVIIa very early could limit bleeding and reduce long-term disability after an intracerebral hemorrhage.

How similar studies have performed: Previous rFVIIa trials reduced hematoma growth but did not show clear overall clinical benefit and raised safety concerns, so this trial tests whether much earlier treatment in selected patients improves outcomes.
