Brief summary

The goal of this clinical trial is to evaluate the efficacy and safety of Nirmatrelvir/Ritonavir in the treatment of the Omicron variant of COVID-19. The main question it aims to answer is: Whether the use of the drug can help patients recover from COVID-19. Patients in both groups were given Lianhua Qingwen Capsule orally, 3 times/day, 6 g/time. oral antipyretic (ibuprofen suspension 10ml) and symptomatic supportive treatment for body temperature \>38.5 ℃. The study group was given Nirmatrelvir 300mg/Ritonavir 100mg orally, q12h, for 5 days, and the control group not given any antiviral drugs.

Primary

MeasureTime frameDescription
Nasal swab COVID-19 nucleic acid testsOn days 4, 7, 9 and 11 of treatmentPatients in both groups underwent nasal swab COVID-19 nucleic acid tests on days 4, 7, 9 and 11 of treatment, and CT values were recorded (CT values of 40 for negative results). Compare the difference in the change of CT values of COVID-19 nucleic acid between two groups of patients
Virus turn negativeFrom date of randomization until the date of first documented progression, assessed up to 5 monthsCompare the first negative conversion(or CT value ≥35) time of coronavirus nucleic acid between two groups
Hospital staysFrom date of randomization until the date of first documented progression, assessed up to 5 monthsCompare the difference in hospitalization time between the two groups strictly according to discharge criteria
Adverse drug reactionFrom date of randomization until the date of first documented progression, assessed up to 5 monthsCompare the adverse drug reactions during hospitalization between two groups
COVID-19 nucleic acid re-positiveFrom date of randomization until the date of first documented progression, assessed up to 5 monthsAfter discharge, patients in both groups continued to be isolated at the isolation point for 7 days and underwent COVID-19 nucleic acid tests daily to compare the COVID-19 nucleic acid re-positive
