As of 1 July 2020, more than 10 million people been confirmed to have infected by SARS-CoV-2, resulting in more than 500,000 deaths. No specific antiviral treatment for the SARS-CoV-2 is currently available, but existing medication could be repurposed.
The investigators therefore propose to conduct an open-label randomized controlled trial on a short course of interferon β-1b and ribavirin combination treatment for patients hospitalized for COVID-19 infection.

The novel coronavirus (SARS-CoV-2), is a single-stranded RNA coronavirus. The virus was first isolated from patients presented with pneumonia in Wuhan in December 2019. It is believed that the virus first emerged from patients working in the Wuhan Seafood Market which also sold contaminated wild animals, consumed as a local delicacy. Sequences of the Wuhan betacoronavirus show similarities to betacoronaviruses found in bats, sharing a common ancestor with the 2003 SARS coronavirus (SARS-CoV).
The SARS-CoV-2 has since spread from China to the rest of the world. As of 1 July 2020, more than 10 million people been confirmed to have infected by SARS-CoV-2, resulting in more than 500,000 deaths. No specific antiviral treatment for the SARS-CoV-2 is currently available, but existing medication could be repurposed.
Previously, the investigators have demonstrated that interferon beta-1b, commonly used in the treatment of multiple sclerosis and lopinavir/ ritonavir, also demonstrated to improve the outcome of MERS-CoV infection in a non-human primate model of common marmoset. More recently, the investigators have demonstrated that the triple combination of interferon β-1b, lopinavir/ ritonavir and ribavirin was significantly more effective in alleviating symptoms and respiratory SARS-CoV-2 viral load than lopinavir/ ritonavir with ribavirin or lopinavir/ ritonavir alone, suggesting that interferon β-1b might be the most potent antiviral among the three and lopinavir/ ritonavir is associated with relatively more side effects including diarrhoea and cardiac arrhythmia.
Therefore, the investigators propose to conduct an open-label randomized controlled trial on a short course of interferon β-1b and ribavirin combination treatment for patients hospitalized for COVID-19 infection.
Patients will be randomly assigned to one of the two groups: the Treatment group: a 5-day course of subcutaneous injection of interferon β-1b 2mL (16 million IU) consecutively and oral ribavirin 400mg twice daily, or the Control group: supportive care alone (1:1).
For patients randomized to the Control group, if the nasopharyngeal swab (NPS) or throat saliva (TS) viral load is still detectable on day 3, the patients will receive the same treatment as in the Treatment group from day 4 to day 8.
