Role of favipiravir remains uncertain in COVID-19. Early treatment with five days oral favipiravir did not prevent disease progression from non-hypoxia to hypoxia in high-risk patients. No beneficial effects were observed in preventing mechanical ventilation, ICU admission, and in-hospital mortality.
A c c e p t e d M a n u s c r i p t 18 moderate to severe diseases. All the recruited patients had risk factors for disease progression and half had evidence of COVID-19 pneumonia. Up to 97.4% of subjects completed the study with outcomes available for evaluation. Patients in intervention group received adequate dosing and duration of favipiravir before the occurrence of clinical deterioration around 4.5 (8.72 ) days from the study enrolment. The use of disease-modifying therapies which could improve clinical outcomes were also equal in both groups.
CONCLUSION Favipiravir did not exert any beneficial effect in preventing clinical deterioration from non-hypoxia to hypoxia among COVID-19 patients with co-morbidity. There was also no effect in reducing incidences of mechanical ventilation, ICU admission, and mortality during hospitalization.
ACKNOWLEDGEMENT The authors would like to thank researchers from all 14 designated COVID-19 public hospitals and Institute for Clinical Research for the contribution in this study. We are grateful of participation from all our patients. We also thank the Director-General of Health Malaysia for his permission to publish this study.
