Yinhu Qingwen Decoction for the Treatment of Mild / Common CoVID-19

Adaptive, Randomized, Single-blind, Three-arm Parallel Controlled Clinical Trial of Yinhu Qingwen Decoction in the Treatment of Mild / Common CoVID-19

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 Decoction as a potential antiviral Chinese medicine based on vivo antiviral studies in CoVID-19, this randomized,three-arm controlled, single-blind trial will evaluate the efficacy and safety of Yinhu Qingwen Decoction (Granula) in patients hospitalized with mild or common CoVID-19 respiratory disease.

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 Decoction (Granula) 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 mean clinical recovery time for patients with mild and common CoVID-19 infection as the primary outcome, and to evaluate the effect of the symptoms relief and virus clearance as well as the clinical safety.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Yin Hu Qing Wen Decoction Group; Based on the standard western medicine treatment, the patients will be given Yinhu Qingwen Decoction (Granula) for 10 days.	Drug: YinHu QingWen Decoction; YinHu QingWen Decoction (Granula) consits of 11 Chinese herbal medicine as Honeysuckle, Polygonum cuspidatum, Schizonepeta, Longspur epimedium, etc. The decoction granula will be dissolved into 600ml decoction and divided to 3 times (once with 200ml). It will be given a 200ml per time, three times a day, for 10 days.; Other: standard western medicine treatment; Standard western medicine treatment is according to the protocol of treatment of CoVID-19 infection according to guideline appoved by National Health Commission of China.
