Pharmacology

Actemra 162 mg/0.9 ml is a recombinant humanized anti-human interleukin 6 (IL 6) receptor monoclonal antibody of the immunoglobulin (Ig) IgG1 subclass. Actemra 162 mg/0.9 ml binds specifically to both soluble and membrane-bound IL 6 receptors (sIL 6R and mIL 6R), and has been shown to inhibit sIL 6R and mIL 6R-mediated signaling. Interleukin-6 is a multi-functional cytokine, produced by a variety of cell types involved in local paracrine function as well as regulation of systemic physiological and pathological processes eg, induction of immunoglobulin secretion, T-cell activation, induction of hepatic acute phase proteins and stimulation of haematopoiesis. Interleukin-6 has been implicated in the pathogenesis of diseases including inflammatory diseases, osteoporosis and neoplasia. The possibility exists for Actemra 162 mg/0.9 ml to affect host defences against infections and malignancies. The role of IL-6 receptor inhibition in the development of malignancies is not known.

Actemra 162 mg/0.9 ml doses exceeding 800 mg per infusion are not recommended in RA or CRS patients.

Interaction of Actemra 162 mg/0.9 ml

Interactions with CYP450 Substrates: Cytochrome P450s in the liver are down-regulated by infection and inflammation stimuli including cytokines such as IL-6. Inhibition of IL-6 signaling in RA patients treated with Actemra 162 mg/0.9 ml may restore CYP450 activities to higher levels than those in the absence of Actemra 162 mg/0.9 ml leading to increased metabolism of drugs that are CYP450 substrates. In vitro studies showed that Actemra 162 mg/0.9 ml has the potential to affect expression of multiple CYP enzymes including CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6 and CYP3A4. Its effect on CYP2C8 or transporters is unknown. In vivo studies with omeprazole, metabolized by CYP2C19 and CYP3A4, and simvastatin, metabolized by CYP3A4, showed up to a 28% and 57% decrease in exposure one week following a single dose of Actemra 162 mg/0.9 ml, respectively. The effect of Actemra 162 mg/0.9 ml on CYP enzymes may be clinically relevant for CYP450 substrates with narrow therapeutic index, where the dose is individually adjusted. Upon initiation or discontinuation of Actemra 162 mg/0.9 ml, in patients being treated with these types of medicinal products, perform therapeutic monitoring of effect (e.g., warfarin) or drug concentration (e.g., cyclosporine or theophylline) and the individual dose of the medicinal product adjusted as needed. Exercise caution when coadministering Actemra 162 mg/0.9 ml with CYP3A4 substrate drugs where decrease in effectiveness is undesirable, e.g., oral contraceptives, lovastatin, atorvastatin, etc. The effect of Actemra 162 mg/0.9 ml on CYP450 enzyme activity may persist for several weeks after stopping therapy

Mode Of Action

Actemra 162 mg/0.9 ml binds to both soluble and membrane-bound IL-6 receptors (sIL-6R and mIL-6R), and has been shown to inhibit IL-6-mediated signaling through these receptors. IL-6 is a pleiotropic pro-inflammatory cytokine produced by a variety of cell types including T- and B-cells, lymphocytes, monocytes and fibroblasts. IL-6 has been shown to be involved in diverse physiological processes such as T-cell activation, induction of immunoglobulin secretion, initiation of hepatic acute phase protein synthesis, and stimulation of hematopoietic precursor cell proliferation and differentiation. IL-6 is also produced by synovial and endothelial cells leading to local production of IL-6 in joints affected by inflammatory processes such as rheumatoid arthritis.

Pregnancy

Based on animal data, may cause fetal harm. Discontinue drug or nursing taking into consideration importance of drug to mother.
