Interventions

Drugs Route Formulation
DanoprevirPrimary Drug Oral Tablet
Interferon alpha Inhalation Spray
RitonavirPrimary Drug Oral Tablet

Ganovo+ritonavir with or without interferon nebulization

Drug: Ganovo+ritonavir+/-Interferon nebulization (Ganovo one tablet (100mg / tablet) at a time, twice a day, up to 14 days. Ritonavir one tablet(100mg / tablet) at a time, twice a day, up to 14 days.With or without spray inhalation of interferon, 50μg / time for adults, twice a day up to 14 days.)

Results

Therapeutic efficacy

Clinical: Results from a clinical study for danoprevir in treatment of COVID-2019 demonstrated normal body temperature for at least 3 days, significantly improved respiratory symptoms, lung imaging showing obvious absorption and recovery of acute exudative lesion; and two consecutive RT-PCR negative tests of SARS-CoV-2 nucleotide acid (respiratory track sampling with interval at least one day). After initiation of danoprevir/ritonavir treatment, the first negative RT-PCR test occurred at a median of two days, ranging from one to eight days, and the obvious absorption in CT scans occurred at a median three days, ranging from two to four days. The trial enrolled eleven patients [2] .

Adverse events

Clinical: Results from a clinical study for danoprevir for treatment of COVID-2019 demonstrated safety and was well tolerated. The trial enrolled eleven patients [2] .
