Brief Summary:
Our aim is to conduct one trial of personalized immunotherapy in patients with SARS-CoV-2 (COVID-19) associated with organ dysfunction and with laboratory findings of macrophage activation syndrome or immune dysregulation. These patients will be selected by the use of a panel of biomarkers and laboratory findings and they will be allocated to immunotherapy treatment according to their needs.

Detailed Description:

Humanity is experiencing since November 2019 a new pandemic by the novel SARS Coronavirus-19 (SARS-CoV-2). As of March 16 2020 170,191 documented case were reported worldwide of which 6,526 died1. The analysis of the clinical characteristics of these patients showed that among those who were critically ill with acute respiratory failure the risk of death was as high as 60%2. Main clinical feature is the presence of comorbidities and age more than 60 years whereas main laboratory findings are leukopenia and lymphopenia with hepatic dysfunction and increase of D-dimers3,4. It is also reported that these patients suffer from intense pro-inflammation where hyper-cytokinemia predominates5,6.

The above characteristics lead to consider two main mechanisms of pathogenesis of this critical condition: macrophage activation syndrome (MAS) and immune dysregulation. Early and correct understanding of the mechanism and management are of prime importance. This can be achieved only through a therapeutic protocol where the early recognition of the immune state can be done with the use of biomarkers and with the delivery of the precise treatment aiming to the correction of the immune dysregulation.

Data of the Hellenic Sepsis Study Group indicate that MAS can be diagnosed with reliability using serum ferritin7. Concentrations greater than 4,420ng/ml possess diagnostic specificity 97.3% and negative predictive value 98%. According to these data, the risk of developing MAS is greater among patients with comorbidities like type 2 diabetes mellitus and heart failure who are prone to hyper-production of interleukin (IL)-1β by tissue macrophages8. A recent retrospective analysis of patients with severe sepsis and MAS showed that the administration of anakinra decreased 28-day mortality by 30%9. Anakinra is the recombinant antagonist of human IL-1β receptor. IL-1β over-production is the hallmark of the pathogenesis of MAS. Results of a phase III study in 906 patients showed that anakinra was a very safe drug: there was neither excess mortality nor increased susceptibility to secondary infections9. Since November 2017 the randomized clinical trial entitled "A trial of validation and restoration of immune dysfunction in severe infections and sepsis, PROVIDE" (EudraCT number: 2017-002171-26, approval 78/17 by the National Ethics Committee, approval IS 75/17 by the National Organization for Medicines, ClinicalTrials.gov NCT03332225). In this study patients with sepsis and laboratory diagnosis of MAS are randomized to treatment with placebo or anakinra for seven days. Enrolment was completed in December 2019 and no drug related adverse events have been reported.

Recent unpublished data of the Hellenic Sepsis Study Group demonstrate that patients with immune dysregulation have profound lymphopenia associated with elevated IL-6. This is in accordance with evidence of the H1N1 pandemic where patients with pneumonia had substantial lymphopenia and increased Τ regulatory lymphocytes (Treg). This increase of Τreg was prominent among patients with comorbidities like diabetes mellitus, chronic heart failure and chronic obstructive pulmonary disease10,11. The IL-6 blocker tocilizumab is a promising candidate for the reversal of this immune dysregulation.

ESCAPE is an address to the personalized management of life-threatening organ dysfunction by SARS-CoV-2. More precisely, patients infected by SARS-CoV-2 associated with MAS and immune dysregulation will be administered treatment with anakinra and tocilizumab respectively.
