Oxygen Atomizing Inhalation of EGCG in the Treatment COVID-19 Pneumonia in Cancer Patients

Epigallocatechin-3-gallate (EGCG) is a major polyphenol of green tea that possesses a wide variety of actions, such as anti-inflammatory, anti-fibrotic, pro-apoptotic, anti-tumorous, and metabolic effects via modulation of a variety of intracellular signaling cascades. In addition, preclinical studies have also emphasized the antiviral activity of epigallocatechin-3-gallate (EGCG), including SARS-CoV-2.In previous studies, we found that EGCG can prevent and cure radiation-induced normal tissue damage in tumor patients. In clinical studies, we found that EGCG can prevent and treat radiation-induced acute radiation esophagitis, acute radiation skin injury, acute radiation oral mucositis with high safety. Thus, we designed this phase I-II clinical study in order to investigate the possible role of EGCG in tumor patients infected with SARS-CoV-2.
