入选标准

  • 1. Written informed consent. Either the patient or his or her medical proxy
  • (or legally acceptable designee) has been adequately informed of the nature and
  • risks of the study and has given written informed consent prior to Screening.
  • In the Netherlands, deferred consent procedure is allowed. In cases of deferred
  • the time of the study physician*s documented decision to include the patient
  • study will serve as *time of consent* with respect to protocol-specific
  • procedures.
  • In all cases where the patient does not sign informed consent for prior to
  • study entry,
  • informed consent from the patient will be obtained as soon as realistically
  • possible after
  • inclusion in the trial and in accordance with the Declaration of Helsinki,
  • ICH-GCP, the
  • Data Protection Directive (Directive 95/46/EC) and national and local
  • regulations.
  • 2. Age 18 years old or greater at the time of consent.
  • 3. An acute intracranial bleeding episode, defined as any amount of blood
  • acutely observed radiographically within the cranium. Patients may have
  • extracranial bleeding (e.g., gastrointestinal, intraspinal) additionally, but
  • the intracranial hemorrhage must be considered the primary bleed.
  • 4. Performance of a head CT or MRI scan demonstrating the intracranial bleeding
  • within 2 hours prior to randomization (the baseline scan may be repeated to
  • meet this criterion).
  • 5. Treatment with an oral FXa inhibitor (apixaban, rivaroxaban, or edoxaban)
  • within 15 hours prior to randomization. If the time of last dose is unknown,
  • the patient is not eligible for the study. If a patient is documented to have
  • an anti-fXa activity > 100 ng/mL within 2 hours prior to consent, they may be
  • enrolled irrespective of the time since last dose (as long as it is known).
  • 6. Time from bleeding symptom onset < 12 hours prior to the baseline imaging
  • scan. Time of trauma (if applicable) or time last seen normal may be used as
  • surrogates for time of symptom onset.

排除标准

  • If a patient meets any of the following criteria, he/she is not eligible to
  • participate in this trial.
  • 1. Planned surgery, including Burr holes for hematoma drainage, within 12 hours
  • after randomization. Minimally invasive surgery/procedures not directly
  • related to the treatment of intracranial bleeding are allowed (e.g., Burr holes
  • for intracranial pressure monitoring, endoscopy, bronchoscopy, central lines*
  • see Section 7.3 and Appendix F).
  • 2. Glasgow Coma score < 7 at the time of consent. If a patient is intubated
  • and/or sedated at the time of consent, they may be enrolled if it can be
  • documented that they were intubated/sedated for non-neurologic reasons within 2
  • hours prior to consent.
  • 3. Estimated intracerebral hematoma volume > 60 mL assessed by the baseline CT
  • 4. Any bleeding into the (intracranial) epidural space.
  • 5. Anticipation that the baseline and follow up brain scans will not be able to
  • use the same imaging modalities (i.e., patients with a baseline CT scan should
  • have a CT scan in follow up; similarly for MRI).
  • 6. Expected survival of less than 1 month.
  • 7. Recent history (within 2 weeks) of a diagnosed Thrombotic Event (TE) or
  • clinically relevant symptoms of the following: Venous Thromboembolism (VTE:
  • e.g., deep venous thrombosis, pulmonary embolism, cerebral venous thrombosis),
  • myocardial infarction, Disseminated Intravascular Coagulation (DIC), cerebral
  • vascular accident, transient ischemic attack, acute coronary syndrome, or
  • arterial systemic embolism within 2 weeks prior to Screening (see Appendix G
  • for DIC scoring algorithm).
  • 8. Acute decompensated heart failure or cardiogenic shock at the time of
  • randomization (see Appendix H for cardiogenic shock definition).
  • 9. Severe sepsis or septic shock at the time of randomization (see Appendix H
  • for sepsis definition).
  • 10. Pregnant or lactating.
  • 11. Receipt of any of the following drugs or blood products within 7 days prior
  • to consent:
  • a. Vitamin K Antagonist (VKA) (e.g., warfarin).
  • b. Dabigatran.
  • c. Prothrombin Complex Concentrate products (PCC, e.g., Kcentra®) or
  • recombinant factor VIIa (rfVIIa) (e.g., NovoSeven®), or anti-inhibitor
  • coagulant complex (e.g., FEIBA®).
  • 12. Past or planned use of andexanet.
  • 13. Treatment with an investigational drug < 30 days prior to consent.
