1 Recombinant Human C1 Esterase Inhibitor (Conestat Alfa) in the Prevention of Severe SARS-CoV-2 Infection in Hospitalized Patients With COVID-19: a Randomized, Parallel-group, Open-label, Multi-center Pilot Trial (PROTECT-COVID-19).

The aim of this study is to analyze if administration of conestat alfa for 72 hours in addition to standard of care (SOC) in patients hospitalized with non-critical SARS-CoV-2 pneumonia (WHO Ordinal Scale Score 3 or 4) reduces the risk of disease progression to Acute Lung Injury (ALI) and Acute Respiratory Distress Syndrome (ARDS).

NCT04414631 Coronavirus Infections Drug: Conestat alfa
MeSH:Infection Communicable Diseases Coronavirus Infections Severe Acute Respiratory Syndrome

Primary Outcomes

Description: Disease severity on the 7-point Ordinal World Health Organization (WHO) scale (for the current study, score 0 will be omitted and score 6 and 7 will be combined). The ordinal scale measures illness severity over time. This endpoint has been suggested by WHO for clinical trials in patients with COVID-19.

Measure: Disease severity

Time: on day 7

Secondary Outcomes

Description: Time to clinical improvement (time from randomisation to an improvement of two points on the seven-category WHO ordinal scale or live discharge from hospital, whichever came first)

Measure: Time to clinical improvement

Time: within 14 days after enrolment

Description: Proportion of participants alive and not having required invasive or non-invasive ventilation

Measure: Proportion of participants alive and not having required invasive or non-invasive ventilation

Time: at 14 days after enrolment

Description: Proportion of subjects with an ALI (defined by PaO2/FiO2 ratio of <300mmHg)

Measure: Proportion of subjects with an ALI (defined by PaO2/FiO2 ratio of <300mmHg)

Time: within 14 days after enrolment

Other Outcomes

Description: Changes in the ordinal WHO scale

Time: from baseline over 14 days

Description: Length of hospital stay in survivors

Measure: Length of hospital stay in survivors

Time: until day 28

Description: Proportion of participants progressing to mechanical ventilation

Measure: Proportion of participants progressing to mechanical ventilation

Time: on day 7 and day 14

Description: Proportion of participants requiring ICU treatment

Description: 28 Ventilator-free days

Measure: 28 Ventilator-free days

Time: until day 28

Description: All-cause mortality

Measure: All-cause mortality

Time: time from randomisation to death within four weeks

Description: Changes in biomarker level CRP

Measure: Changes in biomarker level CRP (mg/l)

Time: until day 14

Description: Changes in biomarker level LDH

Measure: Changes in biomarker level LDH (U/l)

Time: until day 14

Description: Changes in biomarker level D-Dimer

Measure: Changes in biomarker level D- Dimer (yg/ml)

Time: until day 14

Description: Changes in biomarker level Ferritin

Measure: Changes in biomarker level Ferritin (ng/ml)

Time: until day 14

Description: Changes in biomarker level IL-6

Measure: Changes in biomarker level Interleukin 6 (IL- 6) (pg/ml)

Time: until day 14

Description: Changes in lymphocyte count

Measure: Changes in lymphocyte count (cells per microliter of blood)

Time: until day 14

Description: Time to virological clearance of SARS-CoV-2 by PCR from upper or lower respiratory tract samples

Measure: Time to virological clearance of SARS-CoV-2 by PCR from upper or lower respiratory tract samples

Time: time from enrolment to first of 2 negative assays at least 12 hours apart

Description: Proportion of patients receiving additional anti-inflammatory treatment such as tocilizumab or immunoglobulins

Measure: Proportion of patients receiving additional anti-inflammatory treatment such as tocilizumab or immunoglobulins

Time: within 14 days

Description: Time to defervescence (temperature <38.0°C)

Measure: Time to defervescence (temperature <38.0°C)

Time: sustained for at least 48 hours

Description: Time to clinical improvement (defervescence, normalization of oxygen saturation (>93%) and respiratory rate)

Measure: Time to clinical improvement (defervescence, normalization of oxygen saturation (>93%) and respiratory rate) until day 28

Time: until day 28

Description: Duration of supplemental oxygen

Measure: Duration of supplemental oxygen

Time: until day 28

Description: Peak serum concentration of conestat alfa will be measured

Measure: Change in pharmacokinetics of conestat alfa

Time: at baseline, day 1, day 3, day 7, day 10 (during admission) and day 14 (1/- 2days) or discharge date

Description: Change in pharmacodynamics of conestat alfa (C1-inhibitor (CI-INH) concentration)

Measure: Change in pharmacodynamics of conestat alfa (C1-inhibitor (CI-INH) concentration)

Time: at baseline, day 1, day 3, day 7, day 10 (during admission) and day 14 (1/- 2days) or discharge date
