Novel systemic therapies for the treatment of psoriasis

Abstract

Introduction: The immunopathogenesis of psoriasis has led to the discovery and development of several promising treatment options for psoriasis, including those that target the IL-17 and IL-23 pathways as well as small molecules that act on intracellular signaling pathways including the Janus kinase inhibitor and phosphodiesterase-4 inhibitor. Studies have demonstrated efficacy although long-term risks are not fully known. This review looks at novel systemic therapies for psoriasis that have emerged recently.

Areas covered: Systemic treatments for psoriasis that are in the late phase of development were reviewed, with the main focus on the efficacy and adverse effects of individual treatments.

Expert opinion: The future of psoriasis treatment is likely to be based on clinical, genetic and immune biomarkers that will individualize treatment and may potentially optimize disease outcome.
