Compound class: Antibody
Comment: Tocilizumab is an anti-IL-6 receptor mAb, with immunosuppressive action [6] that is approved for chronic autoimmune indications.
Annotated peptide sequences for this antibody are available from its IMGT/mAb-DB record.
Qyuns Therapeutics have a potential tocilizumab biosimilar (QX003S) in Phase 1 evaluation for rheumatoid arthritis (trial registry number ChiCTR1900021808).

In early March 2020, China's National Health Commission issued guidance that allows use of tocilizumab to treat patients with serious COVID-19-induced lung damage. Tocilizumab is predicted to mitigate against the uncontrolled immune response that is triggered by SARS-CoV-2 infection in some patients and which leads to potentially life-threatening lung damage.

Immunopharmacology Comments
Tocilizumab blocks IL-6R activation, which in turn leads to a reduction in cytokine and acute phase reactant production, and eventual symptomatic relief.
