Early Propranolol After Traumatic Brain Injury: Phase II (EPAT: Phase II)

May 12, 2016 updated by: Eric Ley, Cedars-Sinai Medical Center

A Phase II, Dose Escalation, Single Center Study on the Effects of Early Propranolol on Heart Rate, Blood Pressure, and Cerebral Perfusion Pressure in Subjects Who Present With Moderate to Severe Traumatic Brain Injury.

The primary objective of this study is to determine in patients with traumatic brain injury (TBI) the safe dosing of propranolol. Safety will be measured by episodes of bradycardia (heart rate < 60 beats per minute), hypotension (defined as systolic blood pressure < 90) or decreased cerebral perfusion pressure (defined as CPP less than 60mmHg) that are refractive to Brain Trauma Foundation guidelines for treatment. A no-treatment arm will establish the number of episodes of bradycardia, hypotension and reduced cerebral pressure refractory to treatment that occur without propranolol.

Description

Inclusion Criteria:

Exclusion Criteria:

  • pregnancy,
  • patients already treated with beta-blockers,
  • patients treated for antiarrhythmic, immunosuppressive or antiinfective treatment,
  • myocardial infarction during the last 3 months,
  • unstable or severe heart disease,
  • severe chronic obstructive pulmonary disease,
  • serious liver disease,
  • cardiac ischemia that prevents the initiation of vasopressors,
  • signs of cardiac arrhythmia or heart block on EKG,
  • ischemic limb disease that prevents the initiation of vasopressors, vasopressors at maximum dose defined as norepinephrine at 40µg/min or neosynephrine at 300µg/min.

Measure Description
Time Frame
Determine in Patients With Traumatic Brain Injury (TBI) the Safe Dosing of Early Propranolol.
Time Frame: 24 months
The primary outcome is to determine the safety of early propranolol treatment after TBI by recording the number of episodes of bradycardia (heart rate < 60 beats per minute), hypotension (defined as systolic blood pressure < 90) or decreased cerebral perfusion pressure (defined as CPP less than 60mmHg) refractive to treatment.
