Mode of Action

Interleukin-6 receptor antagonist; changes in clinical trials observed include decreased C-reactive protein level to within normal range, decreased values in other pharmacodynamic parameters (eg, rheumatoid factor, erythrocyte sedimentation rate, amyloid A), and increased hemoglobin value

Interaction

Interactions with Other Medications and Other Forms of Interaction: Population pharmacokinetic analyses did not detect any effect of MTX, nonsteroidal anti-inflammatory drugs or corticosteroids on tocilizumab clearance. Tocilizumab has not been studied in combination with other biological DMARDs. The expression of hepatic CYP450 enzymes is suppressed by cytokines, eg, IL-6, that stimulate chronic inflammation. Thus, CYP450 expression may be reversed when potent cytokine inhibitory therapy, eg, tocilizumab is introduced. In vitro studies with cultured human hepatocytes demonstrated that IL-6 caused a reduction in CYP1A2, CYP2C9, CYP2C19, and CYP3A4 enzyme expression. Tocilizumab normalizes expression of these enzymes. The effect of tocilizumab on CYP enzymes (except CYP2C19 and CYP2D6) is clinically relevant for CYP450 substrates with a narrow therapeutic index, and/or where the dose is individually adjusted. In a study in RA patients, levels of simvastatin (CYP3A4) were decreased by 57% one week following a single dose of tocilizumab, to the level similar or slightly higher than those observed in healthy subjects. When starting or stopping therapy with tocilizumab, patients taking medications, which are individually dose-adjusted and are metabolised via CYP450 3A4, 1A2, or 2C9 (eg, atorvastatin, calcium channel blockers, theophylline, warfarin, phenytoin, ciclosporin, or benzodiazepines) should be monitored as doses of these products may need to be adjusted to maintain their therapeutic effect. Given its long elimination t½, the effect of tocilizumab on CYP450 enzyme activity may persist for several weeks after stopping therapy.
