Treatment of Pulmonary Fibrosis Due to 2019-nCoV Pneumonia With Fuzheng Huayu

Study Purpose

Inflammation is the early stage of fibrosis. Serious patients are more likely to develop into pulmonary fibrosis, which affects the recurrence of lung function or even threatens life and health. This study is planned to observe the efficacy and safety of Fuzheng Huayu tablets in the treatment of pulmonary fibrosis after COVID-19.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Pulmonary Fibrosis Due to 2019-nCoV
Additional Details

Corona Virus Disease 2019, which began in December 2019 in Wuhan, Hubei province, has spread rapidly and become an international public health emergency. Although the pathological mechanism of the pneumonia is unclear, some patients developed severe or critical condition due to the continuous development of inflammation. Inflammation is the early stage of fibrosis. After the control of acute symptoms and signs, severe patients often have more manifestations of pulmonary fibrosis, which affects the recurrence of lung function. Fuzheng Huayu tablets has been proved effective in inhibiting MMP activity to protect subepithelial basement membrane which plays a key role in lung injury and interstitial fibrosis. This is a randomized, double blind, multicenter clinical study of pulmonary fibrosis due to 2019-nCoV. The main objective is to evaluate the safety and efficacy of Fuzheng Huayu in pulmonary fibrosis after 2019-nCoV infection. In this study, 136 eligible patients with pulmonary fibrosis due to 2019-nCoV infection will be randomly assigned to one of two treatment groups at a 1:1 ratio. Patients will receive one of two treatment regimens: A. Fuzheng Huayu tablets + basic treatment; B. Placebo tablets + basic treatment. The basic treatment includes N-acetylcysteine 1 capsule three times a day.
