A Study of Efficacy and Safety of Azvudine vs. Nirmatrelvir-Ritonavir in the Treatment of COVID-19 Infection

The COVID-19 pandemic has become a major public health challenge, and the treatment options for the disease are currently limited. The commonly used oral small-molecule anti-COVID-19 drugs in China are Nirmatrelvir-Ritonavir and Azvudine. These drugs have been tested in pre-marketing clinical trials in patients with non-severe COVID-19 infection and have demonstrated therapeutic effects in inhibiting virus transmission and preventing disease progression. However, until now, the efficacy and safety of these drugs in patients with moderate to severe COVID-19 infections remains unclear. Therefore, this study is aiming to compare the efficacy and safety of Azvudine and Nirmatrelvir-Ritonavir in moderate to severe COVID-19 infections. This study will be a multicenter, randomized, controlled clinical trial study in patients hospitalized with moderate to severe COVID-19 infections. Recovery of clinical symptoms, nucleic acid negative conversion, improvement in oxygenation index, and imaging improvement will be used as study endpoints.
