Mortality at Month 1
1 month post injury
Mortality at Month 6
6 months post injury
Glasgow Outcome Scale at 3 Months
Month 3
Glasgow Outcome Scale - Extended (GOS-E)
3 months and 6 months post injury
Short Form (36) Health Survey (SF-36)
3 months and 6 months post injury
- +1 more secondary outcomes
Study Arms (2)
Progesterone
ACTIVE COMPARATORLipid emulsion without progestrone
PLACEBO COMPARATORInterventions
Intravenous administration of 0.71mg/kg/hr for 1hr followed by 0.5mg/kg/hr administered intravenously for an additional 119 hrs.
Intravenous administration equal to 0.71mg/kg/hr for 1hr followed by 0.5mg/kg/hr administered intravenously for an additional 119 hrs.
Eligibility Criteria
You may qualify if:
- Male or female patients between the age of 16 and 70 years, inclusive
- Weight from 45 to 135 kg, inclusive
- Sustained a closed head trauma no more than 8 hours before start of study drug infusion
- TBI diagnosed by history and clinical examination
- Post-resuscitation Glasgow Coma Scale (GCS) score between 3 to 8, inclusive
- At least one reactive pupil (pinpoint pupils due to opioid pain treatment are considered reactive)
- Evidence of TBI confirmed by abnormalities consistent with trauma on CT scan upon admission (diffuse injury II-IV, evacuated and non-evacuated mass lesion, Marshall's CT Classification)
- Indication for ICP monitoring
You may not qualify if:
- Life expectancy of less than 24 hours as determined by the Investigator
- Prolonged and/or uncorrectable hypoxia (Pa02\< 60 mmHg) or hypotension (systolic blood pressure \< 90 mmHg) at the time of randomization
- Any spinal cord injury
- Pregnancy
- Penetrating head injury
- Bilaterally fixed dilated pupils at the time of randomization
- Coma suspected to be primarily due to other causes (e.g. alcohol)
- Pure epidural hematoma
- Preexisting clinically significant disease or chronic condition that can be ascertained at the time of admission and could affect functional outcome
- Severe cardiac or hemodynamic instability prior to randomization
- Known treatment with another investigational drug therapy or procedure within 30 days of injury
- A history of allergic reaction to progesterone and related drugs or any of the components of the infusion
- Any disease, in the opinion of the Investigator, that is unstable or which could jeopardize the safety of the patient and his/her compliance in the study.
- Patients who, in the opinion of the Investigator, would not be able or willing to comply with the protocol through the final visit (6 months post-injury)
