Clinical Trial Summary

The novel coronavirus (SARS-CoV-2) is a new strain of coronavirus found in human in 2019, which causes epidemic worldwide. Novel coronavirus disease (COVID-19) causes acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) in patients with severe COVID-19. Pulmonary edema is the key detrimental feature of ALI/ARDS. Autopsy of patients died from COVID-19 reported that, pulmonary mucus exudation was more severe and obvious than SARS infection. Pulmonary CT scanning and pathological findings also suggest that pulmonary edema caused by inflammatory exudation is a distinguished feature of COVID-19. Vascular endothelial growth factor (VEGF), also known as vascular permeability factor (VPF), is known as the most potent factor to increase vascular permeability, with the induction effect 50,000 times stronger than histamine. Bevacizumab is an anti-VEGF recombinant humanized monoclonal antibody, which has been used in anti-tumor treatment since 2004, with considerable reliability and clinical safety. This trial will provide high level evidence to answer whether bevacizumab is efficacy and safe medication for patients with severe COVID-19.

Description:

Evident increase of VEGF levels in serum has been displayed on novel pneumonia patients. The investigators also conducted a pilot study of 93 patients with severe COVID-19 that confirmed the significantly elevated level of plasma and serum VEGF.

At the beginning of 2020, the investigators proposed the concept of using anti-VEGF treatment for patients with severe COVID-19 and conducted a pilot study (NCT04275414). Among the 27 enrolled participants treated with bevacizumab, it was found that the clinical recovery status, PaO2/FiO2, and pulmonary exudation on imaging were significantly improved than the external controls in the same center during the same period. This provides good preliminary basis for this RCT.
