Recombinant Factor VIIa (rFVIIa) for Hemorrhagic Stroke Trial (FASTEST)

Overview

About this study

The objective of the rFVIIa for Acute Hemorrhagic Stroke Administered at Earliest Time (FASTEST) Trial is to establish the first treatment for acute spontaneous ICH within a time window and subgroup of patients that is most likely to benefit. Our central hypothesis is that rFVIIa, administered within 2 hours from onset with an identified subgroup of subjects most likely to benefit, will improve outcomes at 180 days as measured by the modified Rankin score (mRS) and decrease ongoing bleeding, as compared to placebo. The rationale for this study is that there is no scientifically proven treatment for acute ICH. We will test our central hypothesis by pursuing the following specific aim:

 

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Patients aged 18-80 years, inclusive.
  • Patients with spontaneous ICH.
  • Able to treat with study medication (rFVIIa/placebo) within 120 minutes of stroke onset or last known well.
  • Efforts to obtain informed consent per EFIC guidelines (U.S.) or adherence to country-specific emergency research informed consent regulations (Canada, Germany, Spain, U.K., Japan).

Exclusion Criteria :

  • Score of 3 to 7 on the Glasgow Coma Scale.
  • 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.).
  • ICH volume < 2 cc or ≥ 60 cc.
  • Blood filling 2/3 or more of one lateral ventricle of the brain, OR, blood filling at least 1/3 of both lateral ventricles.
  • Pre-existing disability (mRS > 2).
  • Symptomatic thrombotic or vaso-occlusive disease in past 90 days (e.g., cerebral infarction, myocardial infarction, pulmonary embolus, deep vein thrombosis, or unstable angina).
  • Clinical or EKG evidence of ST elevation consistent with acute myocardial ischemia.
  • Brainstem location of hemorrhage (patients with cerebellar hemorrhage may be enrolled).
  • Refusal to participate in study by patient, legal representative, or family member.
  • Known or suspected thrombocytopenia (unless current platelet count documented above 50,000/μL).
  • Unfractionated heparin use with abnormal PTT.
  • Pro-coagulant drugs within 24 hours prior to patient enrollment into the FASTEST trial (example, tranexamic acid or aminocaproic acid).
  • Low-molecular weight heparin use within the previous 24 hours.
  • Recent (within 90 days) carotid endarterectomy or coronary or cerebrovascular angioplasty or stenting.
  • Advanced or terminal illness or any other condition the investigator feels would pose a significant hazard to the patient if rFVIIa were administered.
  • 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.
  • Planned withdrawal of care or comfort care measures.
  • Patient known or suspected of not being able to comply with trial protocol (e.g., due to alcoholism, drug dependency, or psychological disorder).
  • Known or suspected allergy to trial medication(s), excipients, or related products.
  • Contraindications to study medication.
  • Previous participation in this trial (previously randomized).
  • Females of childbearing potential who are known to be pregnant or within 12 weeks post-partum and/or lactating at time of enrollment.
