Brief Summary:
This is a randomized controlled clinical study on the clinical efficacy of Azvudine and Paxlovid antivirus therapy in COVID-19 patients with high-risk. The objective is to examine the effect of high-risk on the time for COVID-19 patients to achieve 2 continuously negative SARS-CoV-2 nucleic acid test result, and the RT-PCR negative conversion rates in day 7. Patients who meet inclusion criteria will be randomized into the Azvudine group (treatment group) and Paxlovid group (control group).

Condition or disease Intervention/treatment Phase
SARS-CoV-2 Infection Drug: Azvudine Drug: Paxlovid group Not Applicable

Detailed Description:
After enrollment, patients will be randomized into treatment or control groups. Patients received Azvudine orally, for 7 consecutive days (7 doses in total) or Paxlovid orally for 5 consecutive days (10 doses in total). The test for RT-PCR test through either nasopharyngeal or oropharyngeal swabs were conducted on a daily basis from day 3 of their hospitalization until conversion was observed. The primary outcome was the proportion of patients acheive 2 continuously RT-PCR negative for SARS-CoV-2 at 7 days following treatment initiation, including both ORF gene Ct value≥35 and N gene Ct value≥35. Secondary outcomes included 1) the proportion of patients RT-PCR negative for SARS-CoV-2 at 14 days; 2) the time to conversion from a positive RT-PCR test to 2 continuously negative test; 3) 14-day treatment failure rate (need mechanical ventilation or high-flow oxygen therapy or death).
