Cimzia (certolizumab pegol) has a high affinity for human TNFα and binds with a dissociation constant (KD) of 90 pM. TNFα is a key pro-inflammatory cytokine with a central role in inflammatory processes. Cimzia selectively neutralises TNFα (IC90 of 4 ng/ml for inhibition of human TNFα in the in vitro L929 murine fibrosarcoma cytotoxicity assay) but does not neutralise lymphotoxin α (TNFβ). Cimzia was shown to neutralise membrane associated and soluble human TNFα in a dose-dependent manner. Incubation of monocytes with Cimzia resulted in a dose-dependent inhibition of lipopolysaccharide (LPS)-induced TNFα and IL1β production in human monocytes. Cimzia does not contain a fragment crystallisable (Fc) region, which is normally present in a complete antibody, and therefore does not fix complement or cause antibody-dependent cell-mediated cytotoxicity in vitro. It does not induce apoptosis in vitro in human peripheral blood-derived monocytes or lymphocytes, or neutrophil degranulation.
Psoriatic arthritis: Cimzia, in combination with MTX, is indicated for the treatment of active psoriatic arthritis in adults when the response to previous DMARD therapy has been inadequate. Cimzia can be given as monotherapy in case of intolerance to methotrexate or when continued treatment with methotrexate is inappropriate. Plaque psoriasis: Cimzia is indicated for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy.

Ixekizumab is an IgG4 monoclonal antibody that binds with high affinity (<3 pM) and specificity to interleukin 17A (both IL-17A and IL-17A/F). Elevated concentrations of IL-17A have been implicated in the pathogenesis of psoriasis by promoting keratinocyte proliferation and activation, as well as in the pathogenesis of psoriatic arthritis by driving inflammation leading to erosive bone damage and pathological new bone formation. Neutralisation of IL-17A by ixekizumab inhibits these actions.
Secukinumab is a fully human IgG1/k; monoclonal antibody that selectively binds to and neutralises the proinflammatory cytokine interleukin-17A (IL-17A). Secukinumab works by targeting IL-17A and inhibiting its interaction with the IL-17 receptor, which is expressed on various cell types including keratinocytes. As a result, secukinumab inhibits the release of proinflammatory cytokines, chemokines and mediators of tissue damage and reduces IL-17A-mediated contributions to autoimmune and inflammatory diseases. Clinically relevant levels of secukinumab reach the skin and reduce local inflammatory markers. As a direct consequence treatment, secukinumab reduces erythema, induration and desquamation present in plaque psoriasis lesions.
