The COVID-19 pandemic caused by the SARS-CoV-2 virus is a global concern, with remdesivir as the only approved treatment and sarilumab also being considered for off-label use. IL-6 has been associated with severe COVID-19 cases, highlighting the need for further research on its role and the potential benefits of sarilumab in patients.
Introduction: The coronavirus disease 2019 (COVID-19) pandemic, caused by a newly discovered coronavirus (severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2), continues to spread all around the world. Despite the emergency of COVID-19 worldwide, remdesivir is the only treatment that has been recently approved to treat the diseases, and other effective therapies are still lacking. SARS-CoV-2 may cause severe illness in 20% of patients. Based on available data, there is an association between interleukin-6 (IL-6) and severe COVID-19. Sarilumab is a fully human immunoglobulin G1 monoclonal antibody binding to both membrane-bound and soluble IL-6 receptors with high affinity and has been considered for off-label use in the treatment of COVID-19. Areas covered: The present article reviews recently published literature focusing on the pathophysiology of COVID-19 induced cytokine storm, the potential therapeutic role, and important clinical issues of sarilumab in the treatment of COVID-19 patients. Expert opinion: The off-label treatment administration is unavoidable in the critical situation of the COVID-19 pandemic. Further efforts should be directed to determine mechanisms of SARS-CoV-2 induced immune dysregulation as well as indications of sarilumab in the patients with COVID-19 to minimize concerns regarding its off-label administration.
