An Observational, Ambispective Cohort Study of Azvudine in the Treatment of Patients With COVID-19 Pneumonia

Study Overview
=================
Brief Summary
-----------------
This is a multicenter, ambispective observational cohort study. The patients with corona virus disease 2019 (COVID-19) will be included in the study. The patients will be divided into 4 groups according to the treatment mode (Azvudine treatment group within 48 hours after the first positive for nucleic acid, Azvudine treatment group after 48 hours after the first positive for nucleic acid, short course of Azvudine treatment without nucleic acid turning negative, and the control group) . This study aims to analyze the efficacy and safety of Azvudine in the treatment of patients with COVID-19.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Combination therapy group<br>Patients who are treated with the combination therapy of Azvudine and Chinese herbal medicine will be included in this group. The combination therapy is Azvudine treatment (5 mg once a day) within 48 hours of first positive nucleic acid testing for COVID-19, combined with Chinese herbal medicine treatment. | Drug: Azvudine<br>* Azvudine is a small molecular antiviral drug. On August 9, 2022, Azvudine was included in the Diagnostic and therapeutic protocol for COVID-9 in China.<br>|
| Sequential therapy group<br>Patients who are treated with the sequential therapy of Azvudine and Chinese herbal medicine will be included in this group. The sequential therapy is Azvudine treatment (5 mg once a day) after 48 hours of first positive nucleic acid testing for COVID-19, combined with Chinese herbal medicine treatment. | Drug: Azvudine<br>* Azvudine is a small molecular antiviral drug. On August 9, 2022, Azvudine was included in the Diagnostic and therapeutic protocol for COVID-9 in China.<br>|
| Non-standard therapy group<br>Patients are treated with Azvudine combined with Chinese herbal medicine treatment. But Azvudine treatment is discontinued before the nucleic acid turns negative. | Drug: Azvudine<br>* Azvudine is a small molecular antiviral drug. On August 9, 2022, Azvudine was included in the Diagnostic and therapeutic protocol for COVID-9 in China.<br>|
| The control group<br>Patients are treated with Chinese herbal medicine without Azvudine. | |
