Monoclonal antibody (mAb)

Tocilizumab is a recombinant humanized monoclonal antibody IL-6 receptor inhibitor used to treat inflammatory and autoimmune conditions.6 It was first described in the literature in 2003 when Chugai, a subsidiary of Roche began developing IL-6 inhibiting monoclonal antibodies.2 It is currently being investigated to treat severely ill patients with COVID-19.1,7,8

Tocilizumab was granted FDA approval on 8 January 2010.6

Tocilizumab is indicated to treat moderate to severe rheumatoid arthritis, giant cell arteritis, polyarticular juvenile idiopathic arthritis, systemic juvenile idiopathic arthritis, and cytokine release syndrome.6

Associated Conditions

Tocilizumab is an IL-6 inhibiting monoclonal antibody used to treat autoimmune and inflammatory conditions.6 Tocilizumab has a long duration of action as it is generally given every 4 weeks and has a wide therapeutic index.6 Patients should be counselled regarding the risk of infections, GI perforation, and hepatotoxicity.6

Mechanism of action

Interleukin 6 (IL-6) is a pro-inflammatory cytokine produced by cells including T-cells, B-cells, lymphocytes, monocytes, fibroblasts.6 IL-6 rapidly induces C-reactive protein, serum amyloid A, fibrinogen, haptoglobin, and α-1-antichymotrypsin while inhibiting production of fibronectin, albumin, and transferrin.4 IL-6 also induces antibody production, induces cytotoxic T-cell differentiation, and inhibits regulatory T-cell differentiation.4 Tocilizumab binds soluble and membrane bound IL-6 receptors, preventing IL-6 mediated inflammation.6

A 162mg subcutaneous dose given weekly has a Cmax of 51.3±23.2µg/mL and an AUC of 8254±3833µg*h/mL.5 A 162mg subcutaneous dose given every 2 weeks has a Cmax of 13±8.3µg/mL and an AUC of 3460±2530µg*h/mL.5 A 162mg subcutaneous dose given every 4 weeks has a Cmax of 154±42µg/mL and an AUC of 39216±14304µg*h/mL.5

Volume of distribution

In rheumatoid arthritis patients, the central volume of distribution is 3.5L, the peripheral volume of distribution is 2.9L, and the volume of distribution at steady state is 6.4L.6 In giant cell arteritis patients, the central volume of distribution is 4.09L, the peripheral volume of distribution if 3.37L, and the volume of distribution at steady state is 7.46L.6 In pediatric patients with polyarticular juvenile arthritis, the central volume of distribution is 1.98L, the peripheral volume of distribution is 2.1L, and the volume of distribution at steady state is 4.08L.6 In pediatric patients with systemic juvenile idiopathic arthritis, the central volume of distribution is 1.87L, the peripheral volume of distribution is 2.14L, and the volume of distribution at steady state is 4.01L.6

Protein binding

Data regarding the serum protein binding of tocilizumab is not readily available.6


Tocilizumab, like other monoclonal antibodies, is expected to be metabolized to smaller proteins and amino acids by proteolytic enzymes.3

Route of elimination

Data regarding the exact route of elimination of monoclonal antibodies is not readily available.3,6

Half life

The half life of tocilizumab is concentration dependent.6 The terminal half life in rheumatoid arthritis patients is 21.5 days.6 The absorption half life in rheumatoid arthritis and giant cell arteritis patients was 4 days, and in polyarticular juvenile idiopathic arthritis patients and systemic juvenile idiopathic arthritis patients was 2 days.6


The linear clearance in rheumatoid arthritis patients is 12.5mL/h, in giant cell arteritis patients is 6.7mL/h, in polyarticular juvenile idiopathic arthritis patients is 5.8mL/h, and in systemic juvenile idiopathic arthritis is 5.7mL/h.6 Clearance is dose dependent and changes from non linear at low doses to linear at higher doses.6


Data regarding overdoses of tocilizumab are not readily available.6 Patients experiencing an overdose may develop neutropenia.6 In case of overdose, monitor patients for signs of adverse reactions and provide symptomatic and supportive treatment.6
