This is a protocol for severe covid with lenzilumab , if you compare to our moderate protocol is the same except they excluding all patients with any secondary infections , and we accepting all these patients,
oxygen specification is the same.and prove of pneumonia , they just called severe , our protocol said moderate...
And I believe that from inclusion criteria both names maybe correct, but our patients maybe more severe , because of secondary infections admitted..

Study Description
Go to sections
Brief Summary:
The primary objective of this study is to assess whether the use of lenzilumab in addition to current standard of care can alleviate the immune-mediated cytokine release syndrome (CRS) and improve ventilator-free survival in hospitalized subjects with severe or critical COVID-19 pneumonia.
Condition or disease Intervention/treatment Phase
Coronavirus Disease 2019 (COVID-19) Pneumonia
Biological: Lenzilumab
Drug: Standard of Care
Phase 3
Detailed Description:
In COVID-19, high levels of granulocyte macrophage-colony stimulating factor (GM-CSF) and inflammatory myeloid cells correlate with disease severity, cytokine storm, and respiratory failure. The mortality rate for hospitalized COVID-19 patients remains unacceptably high, particularly in patients who progress to invasive mechanical ventilation (IMV). This randomized, double-blind, multicenter, placebo-controlled pivotal phase 3 trial will evaluate the impact of lenzilumab (anti-human GM-CSF monoclonal antibody) on ventilator-free survival in hospitalized, hypoxic patients with COVID-19. The study is also designed to evaluate other key endpoints, including ventilator-free days, duration of ICU stay, incidence of IMV, ECMO and/or death, time to death, all-cause mortality and time to recovery.
Approximately 516 patients will be randomized to receive lenzilumab + SOC vs. placebo + SOC in a 1:1 ratio.

Outcome Measures
Go to sections
Primary Outcome Measures :
Ventilator-free Survival [ Time Frame: Up to Day 28 ]
Secondary Outcome Measures :
Ventilator-free Days [ Time Frame: Up to Day 28 ]
Duration of Intensive Care Unit (ICU) Stay [ Time Frame: Up to Day 28 ]
Incidence of Invasive Mechanical Ventilation, ECMO and/or Death [ Time Frame: Up to Day 28 ]
Time to Death [ Time Frame: Up to Day 28 ]
All-cause Mortality [ Time Frame: Day 28 ]
Time to Recovery [ Time Frame: Up to Day 28 ]
Time to recovery is defined as the first day on which a subject satisfies one of the following 3 categories from the 8-point ordinal scale (Hospitalized, not requiring supplemental oxygen-no longer requires ongoing medical care; Not hospitalized, limitation on activities and/or requiring home oxygen; Not hospitalized, no limitations on activities).
Incidence of severe acute respiratory distress syndrome (ARDS) [ Time Frame: Up to Day 28 ]
Duration of Hospitalization [ Time Frame: Up to Day 28 ]
Time to Improvement in 1 or 2 Categories using 8-point Ordinal Scale [ Time Frame: Up to Day 28 ]
Number of Subjects Alive and Off Oxygen [ Time Frame: Up to Day 60 ]
Percentage of Participants Experiencing Adverse Events [ Time Frame: Up to Day 60 ]
Using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0
Percentage of Participants Experiencing Serious Adverse Events [ Time Frame: Up to Day 60 ]
Using the NCI CTCAE version 5.0
Proportion of Subjects Discharged from Hospital [ Time Frame: Up to Day 60 ]
Time to improvement in oxygenation for > 48 hours [ Time Frame: Up to Day 28 ]
Incidence of Non-invasive Ventilation (or Use of High-flow Oxygen Device) [ Time Frame: Up to Day 28 ]
Time to Clinical Improvement, Defined as NEWS2 < 2 Maintained for 24 Hours [ Time Frame: Up to Day 28 ]
NEWS2 consists of: Physiological Parameters: respiration rate (per minute), SpO2 Scale 1 (%), SpO2 Scale 2 (%), use of air or oxygen, systolic blood pressure (mmHg), pulse (per minute), consciousness and temperature (°C)
Change from Baseline to Day 28 in Clinical status Based on the 8-point Ordinal Scale [ Time Frame: Up to Day 28 ]
Duration of Time on Low-flow or High-flow Supplemental Oxygen [ Time Frame: Up to Day 28 ]
