Recruitment & Eligibility

Status: ot Recruiting

Sex: All

Target Recruitment: 86

Inclusion Criteria

• Clinical diagnosis of brain contusion with lesions within the
supratentorial brain parenchyma totaling > 3 mL in volume per
Investigator assessment of baseline non contrast computed tomography
scan (NCCT) at Screening.
• A score of 5 to 15 on the Glasgow Coma Scale (GCS)
• Functionally independent, in the opinion of the Investigator, prior to
index head injury.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 40
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 120

Exclusion Criteria

• In the judgment of the Investigator, participant is likely to have
supportive care withdrawn within 24 hours.
• Clinical signs of brainstem herniation, in the opinion of the
Investigator.
• NCCT or magnetic resonance imaging (MRI) evidence of penetrating
brain parenchyma. Cerebrospinal fluid leak in isolation is not
exclusionary unless evidence of parenchymal penetration by an external
force (e.g., blunt object, bullet,or depressed skull fracture).
• Any presence of midbrain or posterior fossa injury as assessed by
imaging and clinical examination.
• Presence of concomitant spinal cord injury as assessed by imaging and
clinical examination.
• Polytrauma (intra-abdominal or orthopedic trauma) requiring
operative/surgical management, if known.
Minor fractures requiring splinting or reduction of dislocations are
permitted, as are nonoperative intraabdominal injuries or
placement of noninvasive external fixation devices.
•Use of novel oral anticoagulants (NOACS; including direct thrombin
inhibitors such as dabigatran, or Factor Xa inhibitors such as rivaroxaban
or apixaban), in preceding 3 days prior to the injury, if known.
NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.

Primary Outcome Measures

Name	Time	Method
Main Objective: The primary objective is to determine if BIIB093 reduces brain contusion expansion by Hour 96 when compared to placebo;Secondary Objective: The secondary objectives are to evaluate the effects of BIIB093 on acute neurologic status, functional outcomes, and treatment requirements, to further differentiate the mechanism of action of BIIB093 on contusion expansion by examining differential effects on hematoma and edema expansion, and to determine if BIIB093 improves survival at Day 90 when compared to placebo.;Primary end point(s): Proportion of Participants With Contusion Expansion.<br><br>Participants with contusion expansion will be determined by comparison<br>of the baseline images and the 96-hour scan or the scan obtained prior<br>to any neurosurgical intervention (NSx) or comfort measures only<br>(CMO). NSx includes craniotomy and decompressive<br>craniectomy (DC).;Timepoint(s) of evaluation of this end point: Between 12 hours to 96 hours of start of study treatment infusion

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): - Proportion of Participants With Improvement in Glasgow Outcome<br>Scale – Extended (GOS-E).<br>- Proportion of Participants With Improvement in Modified Rankin Scale<br>(mRS).<br>- Proportion of Participants Requiring Delayed Intubation<br>- Change from Baseline in Absolute Hematoma Volume at Hour 24<br>- Change from Baseline in Absolute Edema Volume at Hour 96<br>- Time to All-cause Death;Timepoint(s) of evaluation of this end point: - GOS-E: Day 90<br>- mRS: Day 90<br>- Delayed Intubation: Day 1 (Hour 24) to Day 4 (Hour 96)<br>- Absolute Hematoma: Baseline up to Day 1 (Hour 24)<br>- Absolute Edema Volume: Baseline up to Day 4 (Hour 96)<br>- All-cause Death: Baseline up to Day 90
