Design outcomes

Primary

MeasureTime frame
Main Objective: It has been described that in patients with critical COVID-19 disease with ARDS in the Intensive Care Unit there is significant hydrogen sulfide (H2S) deficiency. H2S exerts significant anti-inflammatory effects while competing with IL-6. Sodium thiosulfate (STS) is a known H2S donor available for intravenous administration used for to treat cyanide poisoning and the side effects of cisplatin and is being investigated for its cardioprotective effect in patients with myocardial infarction. The aim of this study is to determine whether administration of sodium thiosulfate as a slow-release hydrogen sulfide donor could improve the outcome of critically ill patients with confirmed COVID-19. ;Secondary Objective: A secondary purpose is to describe data on the clinical efficacy of administration of up to three doses of STS in critically ill patients with confirmed COVID-19. ;Primary end point(s): Comparison of treatment-emergent serious and non-serious adverse events between treatment groups. ;Timepoint(s) of evaluation of this end point: Day 28

Secondary

MeasureTime frame
Secondary end point(s): Comparison of treatment groups below: -WHO-CPS on day 7 from inclusion in the study -WHO-CPS on day 14 from inclusion in the study -WHO-CPS on day 28 of inclusion in the study -Average value of the total SOFA score on day 7 -Hydrogen sulfide concentrations daily until day 7 in patient’s blood serum. -Cytokine concentrations daily until day 7 in patient’s blood serum. -Production of cytokines from mononuclear cells of patient’s blood on days 1,4 and 7 ;Timepoint(s) of evaluation of this end point: Day 7 Day 14 Day 28 Day 1-7 Day 1,4,7
