Study Description

Brief Summary

The novel identified coronavirus (SARS-CoV-2) in 2019 causes an nationwide outbreak as well as public health crisis in China, and expands globally. Pulmonary edema is one of the most detrimental symptoms and usually presents in severe and critical coronavirus disease (COVID-19), resulting in dyspnea, acute lung injury (ALI) ,acute respiratory distress syndrome (ARDS), and even death. Recent evidence revealed higher levels of blood Vascular Endothelial Growth Factor (VEGF) in COVID-19 patients compared with healthy controls. VEGF is considered as the most potent vascular permeability inducers. Numerous studies have revealed that VEGF was a key factor and a potential therapeutic target in ALI and ARDS. Bevacizumab, an anti-VEGF drug, approved by the FDA on February 26, 2004 and widely used in clinical oncotherapy, is a promising drug for ALI/ARDS in COVID-19 through suppression of pulmonary edema.

Detailed Description

In December 2019, a new identified coronavirus (SARS-CoV-2) outbreak in Wuhan, causes public health crisis in China and spreads worldwide. On February 11,2020, the World Health Organization officially named the disease caused by the new coronavirus "COVID-19". The Chinese Government takes stronger and harsher measures to control the progression of its outbreak. Meanwhile, five editions of "Diagnosis and Treatment for Novel Coronavirus-Infected Pneumonia" has been timely and continuously issued, which play extremely important roles in guiding the clinical management of COVID-19 nationwide in China.

The symptoms of human infection with SARS-CoV-2 are generally fever, fatigue, dry cough and dyspnea. Noteworthy, a considerable percentage of COVID-19 cases have rapidly progressed to severe and critical type, among which acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the most common complications, resulting in a large number of pneumonia hospitalized patients requiring supplemental oxygen, mechanical ventilation, or even ECMO.Pulmonary edema is a detrimental feature as well as a key causal factor of ALI/ARDS.

Vascular Endothelial Growth Factor (VEGF) is considered as the most potent vascular permeability inducers. Recent evidence has revealed higher VEGF levels in COVID-19 patients compared with healthy controls. The rise of VEGF levels may be caused by hypoxia, severe inflammation, and upregulation of the infected respiratory tract epithelium itself. Numerous studies have confirmed a key role of VEGF as potential therapeutic target in acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) due do increase vascular permeability and induce pulmonary edema.

Thus, Bevacizumab, an anti-VEGF medication, may offer a unique approach to treat ALI/ARDS caused by COVID-19. Bevacizumab is a humanized monoclonal antibody with long half-life. It has been approved by the FDA on February 26, 2004 and widely used in clinical oncotherapy, with the pharmacokinetics and pharmacodynamics having been widely understood. Therefore, Bevacizumab is a promising drug for the treatment of ALI/ARDS as well as reduction of mortality in severe and critical COVID-19 patients through suppression of pulmonary edema.

Outcome Measures

Primary Outcome Measures

Partial arterial oxygen pressure (PaO2) to fraction of inspiration O2 (FiO2) ratio [24 hours]
Partial arterial oxygen pressure (PaO2) to fraction of inspiration O2 (FiO2) ratio
Partial arterial oxygen pressure (PaO2) to fraction of inspiration O2 (FiO2) ratio [7 days]
Partial arterial oxygen pressure (PaO2) to fraction of inspiration O2 (FiO2) ratio

Secondary Outcome Measures

Rate of improvement of oxygen-support status [28 days]
The oxygen-support status includes 6 levels: mechanical ventilation, non-invasive ventilation, a transition status of alternate use of non-invasive ventilation and high-flow oxygen, high-flow oxygen, low-flow oxygen and ambient air. The improvement of oxygen-support status is defined as switch from a higher level of oxygen-support to a lower level.
The change of areas of pulmonary lesions shown on chest radiological imaging (chest CT or X-ray) [7 days]
The areas of pulmonary lesions are analysised by a professional imaging software.
