The Efficacy of Azvudine and Paxlovid in High-risk Patients With COVID-19: A Prospective Randomized Controlled Trial

Overview

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).

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).
