OBJECTIVE: To evaluate the therapeutic effectiveness of favipiravir combined with inhaled interferon beta-1b in adult patients hospitalized with moderate to severe COVID-19 pneumonia.
METHODS: A randomized, open-label controlled trial of oral favipiravir in adults hospitalized with moderate to severe COVID-19 pneumonia from June 22nd 2020 to August 13th 2020 was conducted. Patients were randomly assigned to receive either a combination of favipiravir with interferon beta-1b by inhalation aerosol or hydroxychloroquine (HCQ). The outcome endpoints included improvement in inflammatory markers, lower length of hospital stay (LOS), discharges and lower overall 14-day mortality.
RESULTS: A total of 89 patients underwent randomization with 49% (n = 44) assigned to favipiravir and 51% (n = 45) assigned HCQ. The overall mean age was 55 ± 14 years and 58% (n = 52) were males. There were no significant differences in the inflammatory biomarkers at hospital discharge between the two groups; C-reactive protein (p = 0.413), ferritin (p = 0.968), lactate dehydrogenase (p = 0.259) and interleukin 6 (p = 0.410). There were also no significant differences between the two groups with regards to the overall LOS (7 vs 7 days; p = 0.948), transfers to the ICU (18.2% vs 17.8%; p = 0.960), discharges (65.9% vs 68.9%; p = 0.764) and overall mortality (11.4% vs 13.3%; p = 0.778).
CONCLUSIONS: No differences in clinical outcomes were found between favipiravir plus inhaled interferon beta-1b and hydroxychloroquine in adults hospitalized with moderate to severe COVID-19 pneumonia.

There was no control group receiving placebo or standard therapy, so it is very difficult to know what, if any, benefit either had - just that they had similar value (or lack of value).
Small study, but adding to the growing literature of limited meaningful therapeutic options for COVID-19 pneumonia.
