7. Prolonged and/or uncorrectable hypoxia, as judged by the investigator (PaO< 60 mmHg) or hypotension (SBP< 90 mmHg) upon admission.
8. Suspected or confirmed pregnancy (positive urine sample, followed by confirmational serum human chorionic gonadotropin (HCG) pregnancy test).
9. Immunosuppression due to drugs (for ex. ciclosporin) or disease (e.g. human immunodeficiency virus (HIV), malignancy).
10. Known or a medical history of serious chronic viral or fungal infection.
11. Known or a medical history of active mycobacterial infection or antituberculous treatment.
12. Known or a medical history of any allergic reactions and/or anaphylactic reactions towards ciclosporin, egg, peanuts or soya-bean proteins.
13. Ongoing preinjury therapy with any of these drugs:
rosuvastatin, tacrolimus, Hypericum perforatum (St.John´s Wort; a herbal dietary supplement), stiripentol, aliskiren, bosentan, diltiazem, verapamil and antiepileptics.
14. Participation in other clinical trials.
15. Any significant disease or disorder including abnormal laboratory tests which, in the opinion of the investigator, may either put the patient at risk because of participation in the study, or may influence the results of the study. |

E.5 End points |
E.5.1 | Primary end point(s) |
• Non-compartmental analysis (NCA) of pharmacokinetics of ciclosporin in whole blood.
• Safety parameters and adverse events, including:
1. Ciclosporin levels in whole blood.
2. Markers of nephrotoxicity: plasma creatinine, plasma Cystatin-C and blood urea nitrogen.
3. Markers of hepatotoxicity: prothrombin time (PT), aspartate transaminase (AST), alanine transaminase (ALT) and bilirubin.
4. Intracranial Pressure (ICP)
5. Assessment of infections: according to standard procedures at intensive care unit.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
At database lock N#1, when data has been obtained from 10 evaluable patients on first dosing step, then consecutively at the final database lock, when data has been obtained for additonal 10 evaluable patients on the second dosing step. |
|
E.5.2 | Secondary end point(s) |
• Ciclosporin levels in cerebrospinal fluid (CSF).
• Safety biomarkers for nephrotoxicity: Kidney Injury Molecule (KIM)-1, creatinine and Cystatin-C in urine samples.
The following only if available:
• Biomarkers of brain injury in brain tissue, measured using microdialysis in the most and least traumatised side.
• Brain tissue oxygen (BrTiO2) measured directly using probe.
• Biomarkers of brain injury in CsA and/or blood, if possible
The below explorative endpoint will be reported separately:
• Electroencephalography (EEG).
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
-The secondary endpoint: Biomarkers of brain injury in brain tissue, measured using microdialysis, will be included, and the data accessible at database lock N=#1 (after 10 patients in the first dosing Group). These data will not be part of the IDSMB interimanalysis assessment. Also, these data (from the 10 patients) will not be evaluated until after the final database lock: (after 20 patients; after both dosing groups).
-All secondary endpoints will be evaluated at the final database lock , when results have been obtained from 20 evaulable patients.
-For the secondary exploratory endpoint this will be reported separately, after the final database lock. |
