About

To evaluate the efficacy of subcutaneous ropeginterferon alfa 2b ( P1101 combined with standard of care (SOC) compared with standard care alone in adult COVID-19 patients with comorbidities.

Full description

This is a multi-center, open label, control study to evaluate the efficacy and safety of ropeginterferon alfa-2b in the treatment of adult COVID-19 patients with comorbidities. Adult COVID-19 patient with the specific comorbidities and being non-responder to the other anti-SARS-CoV-2 drugs, i.e., remdesivir, nirmatrelvir/ritonavir, and molnupiravir, or the patients who is not suitable to receive the other anti-SARS-CoV-2 drugs by investigator's judgement and has positive result (Ct <30) 14 days after the symptom onset of COVID-19 will be enrolled. The eligible patients will be randomized to receive the ropeginterferon alfa-2b plus SOC (study group) or to receive SOC alone (control group). For study group, a single dose of 250 μg ropeginterferon alfa-2b will be subcutaneous administrated at Day 1 visit. For patients who still have positive result (Ct <30) in SARS-CoV-2 RT-PCR at Day 15 and Day 29, the second dose of ropeginterferon alfa-2b at 350 μg and the third dose at 500 μg will be administered, respectively. For control group, patients will receive the SOC alone. The efficacy and safety of ropeginterferon alfa-2b will be evaluated.
