E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to determine if BIIB093 reduces brain contusion expansion by Hour 96 when compared to placebo |
L’obiettivo primario dello studio è determinare se BIIB093 riduce la contusione cerebrale entro 96 ore rispetto al placebo. |
|
E.2.2 | Secondary objectives of the trial |
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. |
Gli obiettivi secondari sono di valutare gli effetti del BIIB093 sullo stato neurologico acuto, sugli esiti funzionali e sui requisiti di trattamento, per differenziare ulteriormente il meccanismo d'azione di BIIB093 sull'espansione della contusione esaminando gli effetti differenziali sull'espansione dell'ematoma e dell'edema e per determinare se il BIIB093 migliora sopravvivenza al giorno 90 rispetto al placebo. |

E.3 | Principal 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. |
• Diagnosi clinica della contusione cerebrale con lesioni all'interno del parenchima cerebrale sopratentoriale per un totale> 3 ml di volume per valutazione di Investigator della TCCT allo screening. • Punteggio da 5 a 15 sulla Glasgow Coma Scale (GCS) • Funzionalmente indipendente, secondo il parere dello sperimentatore, prima dell'infortunio alla testa indice. |
|
E.4 | Principal 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• In the judgment of the Investigator, participant is likely to have supportive care withdrawn within 24 hours.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. |
• A giudizio dello sperimentatore, è probabile che il partecipante ritiri l'assistenza di supporto entro 24 ore. • Segni clinici d' erniazione del tronco cerebrale, secondo il parere dello sperimentatore. • Prova NCCT o risonanza magnetica (MRI) di penetrazione parenchima cerebrale. La perdita di liquido cerebrospinale in isolamento non è esclusiva a meno che non sia stata dimostrata la penetrazione del parenchima da parte di una forza esterna (ad es. Oggetto contundente, proiettile o frattura cranica depressa). • Qualsiasi presenza di lesione della mesencefalo o della fossa posteriore, valutata mediante imaging e esame clinico. • Presenza d' una concomitante lesione del midollo spinale valutata mediante imaging e esame clinico. • Polytrauma (trauma intra-addominale o ortopedico) che richiede una gestione operativa / chirurgica, se nota. Sono consentite piccole fratture che richiedono lo splintaggio o la riduzione delle lussazioni, così come le lesioni intra-addominali non chirurgiche o o posizionamento di dispositivi di fissaggio esterni non invasivi. • Uso di nuovi anticoagulanti orali (NOACS, inclusi inibitori diretti della trombina come dabigatran o inibitori del fattore Xa come rivaroxaban o apixaban) nei precedenti 3 giorni precedenti la lesione, se noto. possono essere applicati altri criteri d' esclusione definiti dal protocollo. |

E.5 End points |
E.5.1 | Primary end point(s) |
Proportion of Participants With Contusion Expansion.
Participants with contusion expansion will be determined by comparison of the baseline images and the 96-hour scan or the scan obtained prior to any neurosurgical intervention (NSx) or comfort measures only (CMO). NSx includes craniotomy and decompressive craniectomy (DC). |
Proporzione di partecipanti con espansione della contusione.
I partecipanti con espansione della contusione saranno determinati confrontando le immagini di base e la scansione a 96 ore o la scansione ottenuta prima di qualsiasi intervento neurochirurgico (NSx) o solo misure di comfort (CMO). NSx include craniotomia e craniectomia decompressiva (DC). |
