Clinical Trial Summary

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.

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.

• 5. Known history or presence of poorly controlled or clinically significant medical conditions that are not suitable to be enrolled, at the discretion of the investigator, e.g., major psychiatric (including but not limited to those with severe depression, severe bipolar disorder, schizophrenia, suicidal ideation or history of suicidal attempt) or poorly controlled autoimmune diseases;
• 6. Clinically significant medical conditions known to interfere with absorption, distribution, metabolism or excretion of the study drugs;
• 7. Patients treated by monotherapy of telbivudine or any other combination therapy with telbivudine within 1 month prior to screening;

Intervention

Drug:
• Ropeginterferon alfa-2b
A maximum of 3 doses of ropeginterferon alfa-2b will be given biweekly during the whole study period. A single dose of 250 µg ropeginterferon alfa-2b will be subcutaneous administrated at Day 1 visit. SARS-CoV-2 antigen test will be conducted at D15 and D29 visits. For patients who still have positive result in SARS-CoV-2 antigen test at Day 15 visit, the second dose of ropeginterferon alfa-2b at 350 µg will be subsequently administered at Day 15 visit. For patients who still have positive result in SARS-CoV-2 antigen test at Day 29 visit, the third dose of ropeginterferon alfa-2b at 500 µg will be administered at Day 29 visit.

Procedure:
• SOC
SOC includes infection prevention and control measures, supportive care, dexamethasone, and antiviral agents. The SOC is based on the Taiwan Centers for Disease Control (CDC) guidance and investigator's discretion.
