Contra Indications

Hypersensitivity

Precautions

Serious infections leading to hospitalization or death (ie, tuberculosis; bacterial, invasive fungal, viral, or other opportunistic infections) have occurred with use Stop therapy if serious infection occurs; can restart if infection is controlled Test for latent tuberculosis before initiating; if positive, initiate tuberculosis therapy before starting tocilizumab Continue to monitor all patients for active tuberculosis during therapy Lactation: unknown whether distributed in breast milk, do not breast feed

Pregnancy-Lactation

Pregnancy Limited available data in pregnant women are not sufficient to determine whether there is a drug-associated risk for major birth defects and miscarriage Monoclonal antibodies are increasingly transported across placenta as pregnancy progresses, with largest amount transferred during third trimester; risks and benefits should be considered prior to administering live or live-attenuated vaccines to infants exposed to therapy in utero Lactation No information is available on presence of tocilizumab in human milk, the effects of drug on breastfed infant, or effects of drug on milk production Maternal immunoglobulin G (IgG) is present in human milk; if tocilizumab is transferred into human milk, effects of local exposure in gastrointestinal tract and potential limited systemic exposure in infant to tocilizumab are unknown Developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and potential adverse effects on breastfed child from tocilizumab or from underlying maternal condition

Interactions

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.

Adverse Effects

Side effects of Tocilizumab : >10% SC injection site reactions (7.1-10.1%) 1-10% Upper respiratory tract infections, Nasopharyngitis, Headache, Hypertension, Increased ALT, Infusion related skin reactions (eg, rash, pruritus, urticaria), Dose related adverse reactions including decreased neutrophil count <1000/cu.mm, decreased platelets <100, 000/cu.mm, Lipid elevations, Mouth ulcerations, Gastritis, Upper abdominal pain

Mechanism 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
