Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the (preliminary) efficacy of IFN-? as adjunctive treatment in combination with standard therapy for the treatment of patients presenting with septic shock, by assessment of a series of surogate immunological parameters. ;Secondary Objective: A secondary aim will be to evaluate markers (including mHLA-DR expression) that are currently used to identify patients with immunoparalysis who will benefit from immunotherapy, and to monitor the patient’s immunological response to IFN-?.;Primary end point(s): The primary endpoint is the TNF-a secretion by ex vivo LPS-stimulated leukocytes as a marker of immunosuficiency/antimicrobial response. ;Timepoint(s) of evaluation of this end point: at admission and at days 0, 2, 7, 14, and 28 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Outcome of bacterial infection (occurrence of secondary and/or opportunistic infections, duration of antibacterial treatment, microbiological evaluation) - Hemodynamic stability (noradrenalin infusion rate, amount of infused fluids per day, amount of urine produced per day, daily fluid balance) - Mortality (including time to death) at week 2 and week 6 after end of treatment (all causes) - Length of stay at ICU and duration of hospitalization - Organ function: * Cardiovascular function: lactate level, vasopressor usage, and cardiovascular Sequential Organ Failure Assessment (SOFA) score * Respiratory function: oxygenation index, PaO2/FiO2 (P/F) ratio, and respiratory SOFA score * Renal function: creatinin level, urine ouput, renal replacement therapy usage, and renal SOFA score * Hematologic function: hematologic SOFA score * Hepatic function: Hepatic SOFA score - Production of cytokines by leukocytes ex vivo stimulated with various stimuli (including LPS, peptidoglycan, candida) - Markers of “immune status” (including mHLA-DR and PD-1 expression, IL-6 plasma concentration) - To determine the correlation between the level of immunoparalysis (indicated by the commonly used marker mHLA-DR and new markers of “immune status” found), and effectiveness of IFN-? (indicated by TNF-a secretion by ex vivo LPS-stimulated PBMC’s). - Transcriptional activity of leukocytes, including microarrays with a focus on inflammatory pathways - Changes in phenotype or gene expression caused by mechanisms other than changes in the underlying DNA sequence (epigenetic modifications);Timepoint(s) of evaluation of this end point: at admission and at days 0, 2, 7, 14, and 28 | — |
