| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| The aim of the study is to determine the safety and tolerability of SLV334 after a single intravenous (i.v.) dose of 1000mg SLV334 and after multiple i.v. doses of 1000mg SLV334 and 2000mg SLV334 (up to 3 days, b.i.d.)compared to placebo in patients with moderate and severe Traumatic Brain Injury (TBI). |  | 
| E.2.2 | Secondary objectives of the trial | 
| - To determine the pharmacokinetics of SLV334 after a single dose of 1000mg SLV334 and after multiple doses of 1000mg SLV334 and 2000mg SLV334 (up to 3 days, b.i.d.) in subjects with moderate and severe TBI  - To assess the effect of SLV334 on clinical assessments such as intracranial pressure (ICP), cerebral perfusion pressure (CPP)and therapy intensity level (TIL)  - To assess in a sub-sample of subjects (those with a ventricular catheter or microdialysis), SLV334 levels in the cerebrospinal fluid (CSF) and/or microdialysis compared to systemic levels  - To assess in a sub-sample of subjects (as previously), the influence of single and multiple doses of i.v.SLV334 on neurohormone activities/conc.s related to the mode of action (neutral endopeptidase (NEP) and endothelin converting enzyme (ECE) and markers for apoptosis, necrosis and neural damage in the cerebrospinal fluid (CSF)and/or microdialysis compared to placebo and compared to systemic (plasma) levels. |  |

| FARMACOCINETICA/FARMACODINAMICA: Versione:Em.2 Data:2008/11/27 Titolo:Compreso nel protocollo principale dello studio Obiettivi:Determinare la farmacocinetica di SLV334 dopo una singola somministrazione di 1000 mg SLV334 e dopo dosaggi multipli di 1000 mg SLV334 e di 2000 mg SLV334 (fino a 3
 giorni, b.i.d.) in soggetti con TBI moderata e severa.
 Determinare leffetto di SLV334 sugli accertamenti clinici quali la pressione intracranica
 (ICP), la pressione di perfusione cerebrale (CPP) e il livello di intensita` della terapia (therapy
 intensity level, TIL).

| E.3 | Principal inclusion criteria | 
| 1. Male or female subjects, age between 16 and 70 years, inclusive (the lower age limit will be 18 if required by local regulations);  2. TBI diagnosed by history, clinical examination with Glasgow Coma Scale (GCS) of 12 or less;  3. Evidence of TBI confirmed by abnormalities on Computed Tomography (CT scan);  4. Clinical indication to monitor ICP;  5. Randomization and drug treatment with study drug possible within 8 hours after closed (non-penetrating) head trauma;  6. Informed Consent is given |  | 
| E.4 | Principal exclusion criteria | 
| 1. Life expectancy of less than 24 hours;  2. Any spinal cord injury;  3. Suspected or confirmed pregnancy or lactating women;  4. Penetrating head injury (e.g.missile, gunshot or stab injuries);  5. Bilaterally fixed dilated pupils at the time of randomization;  6. Coma suspected to be primarily due to other causes than head injury (e.g.drug or alcohol overdose);  7. Pure epidural hematoma (lucid interval and absence of structural brain damage on CT scan);  8. Known or CT scan evidence of previous major cerebral damage or known clinical sequelae of prior spinal cord injury;  9. Any severe concomitant condition (e.g.cancer, renal, hepatic, coronary disease or major psychiatric disorder) that can be ascertained at admission and could affect functional outcome;  10. Severe multiple trauma or major organ failure (uncontrolled visceral bleeding, unstable cardio-respiratory or renal function);  11. Severe cardiac or hemodynamic instability after resuscitation (Systolic blood pressure ≤ 100mmHg)consistent with point 1 above;  12. Known treatment with another investigational drug therapy or intervention within 30 days of injury. |  | 
| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| Safety:  The primary outcome measure will be the safety of SLV334 including mortality, adverse events (AE),serious adverse events (SAE), vital signs, laboratory variables and ECG    Pharmacokinetics:  In cohorts 1-3,pharmacokinetics measurements of SLV334 plasma levels will be measured at 6 time-points up to 24 hours after start of the first infusion. In cohort 4, plasma levels of SLV334 will be measured at 12 time-points up to 24 hours after the first dose of Day 3.    Pharmacodynamics:  - Biomarkers for Endothelin Converting Enzyme (ECE) and Neutral Endopeptidase (NEP): ET-1, Big-ET-1, BNP, ANP and cGMP  - Biomarkers for apoptosis and necrosis (alpha II-spectrin breakdown products, UCH-L1 and BA252) |  |
