• Introduction: Tocilizumab is a recombinant humanized monoclonal antibody IL-6 receptor inhibitor used to treat inflammatory and autoimmune conditions. It was first described in the literature in 2003 when Chugai, a subsidiary of Roche began developing IL-6 inhibiting monoclonal antibodies. Tocilizumab was granted FDA approval on 8 January 2010 to treat a number of inflammatory and autoimmune disorders, such as different types of arthritis and cytokine release syndrome. It was later approved by Health Canada on 30 April 2010. After being investigated to treat severely ill patients with COVID-19, tocilizumab was approved by the European Commission in December 2021 to treat COVID-19 in adults receiving systemic corticosteroids and supplemental oxygen or mechanical ventilation. Subsequently, it was granted approval by Health Canada and the FDA in October and December 2022, respectively. Tocilizumab-bavi, a biosimilar drug, was approved by the FDA in September 2023.
