General information about the trial
|
|||
Main objective of the trial |
The primary objective is to investigate whether continuous infusion of iloprost at a dose of 1 ng/kg/min for 72-hours reduces the severity of respiratory failure in the ICU as compared to placebo.
|
||
Protection of trial subjects |
Patients included in this trial is admitted to the ICU with COVÌD19 requiring respiratory support, therefore these patients will receive the best possible care and monitored closely during their hospital stay.
|
||
Background therapy |
Standard of care for treatment of COVID19 | ||
Evidence for comparator |
Crystalloids are the recommended volume therapy for patients with septic. We have therefore chosen that the placebo should be saline 0.9 % (NaCl) to maintain blinding in the trial as iloprost is diluted in saline. Patients receiving placebo will receive an equal volume of fluid administered in the same way as the iloprost infusion. | ||

Screening details |
Patients are subject for screening if they are 18 years old or above and admitted to an ICU with confirmed COVID19 infection requirering mechanical ventilation. However patients can only be included if souble thrombomodulin is 4 ng/mL or above. | |||||||||

Blinding implementation details |
The trial is double-blinded with saline 0.9 % (NaCl) as placebo to maintain blinding. iloprost is diluted in saline and therefore both solutions are colorless fluids. Patients receiving placebo will receive an equal volume of fluid administered in the same way as the iloprost infusion. The preparation of trial medication will be done by an unblinded nurse, outside the ICU´s, who will be responsible for preparing the investigational drug so that it can be administered in blinded fashion.

Timeframe for reporting adverse events |
SAE and SAR are collected from baseline to day 7
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Adverse event reporting additional description |
Only selected serious adverse events and serious adverse reaction are collected as these patients are severily ill. Therefore, recording of all AE and SAEs in the CRF will not add valuable information to the patient’s safety in this trial and will make it difficult be distinguish the real safety signal and those sight of the significant reactions
