Overview
Brief Summary
In December 2019, Wuhan, in Hubei province, China, became the center of an outbreak of pneumonia caused by CoVID-19, and the number of cases of infection with CoVID-19 identified in Wuhan increased markedly over the later part of January 2020, with cases identified in multiple other Provinces of China and internationally.Given no specific antiviral therapy for CoVID-19 infection and the availability of Yinhu Qingwen Granula as a potential antiviral Chinese medicine based on vivo antiviral studies in CoVID-19, this adaptive, randomized,double-blind,controlled trial will evaluate the efficacy and safety of Yinhu Qingwen Granula in patients hospitalized with severe CoVID-19.
Detailed Description
In December 2019, Wuhan, in Hubei province, China, became the center of an outbreak of pneumonia caused by CoVID-19, and the number of cases of infection with CoVID-19 identified in Wuhan increased markedly over the later part of January 2020, with cases identified in multiple other Provinces of China and internationally.The clinical spectrum of CoVID-19 infection appears to be wide,including asymptomatic infection, mild upper respiratory disease, severe viral pneumonia with respiratory failure, and even death. However,there is no specific antiviral therapy for CoVID-19 infection, which provides a window of opportunity for testing candidate antiviral therapies. Previous experiences with SARS and MERS-CoV, highlight the need of the early intervention with Chinese medicine, and so as for CoVID-19 infection. The treatment of Chinese medicine for CoVID-19 infection suggested its benefits to improve of clinical outcomes, reduce the risk of disease progression, accelerate recovery, and reduce intensive supportive care and long-term hospitalization.Yinhu Qingwen Granula was a kind of herbal granula made from "Yinhu Qingwen Decoction", which consists of 11 common non-toxic traditional Chinese medicine such as Polygonum cuspidatum, Honeysuckle, Nepeta, Ligustrum lucidum. Previous vivo antiviral studies showed its activity for the inbition of CoVID-19. This clinical trial is planned to evaluate the improvement of the changes in the ratio of PaO2 to FiO2 from the baseline for patients with severe CoVID-19 as the primary outcome, and to evaluate the effect of the symptoms relief and virus clearance as well as the clinical safety.
