Psoriasis, a chronic immune-mediated skin disorder is associated with significant physical, psychological, and quality of life impairments. Along with well-documented genetic and environmental factors, immunological factors also contribute to the pathogenesis of psoriasis. Among the immunological factors, CD6 - dependent T-cell proliferation to form Th1 and Th17 cells play a major role in the pathogenesis of psoriasis. Itolizumab is the first humanized IgG1 monoclonal antibody, which selectively targets CD6. Areas covered: The current article presents the pharmacology of itolizumab and provides a review of the currently available data on the efficacy and safety of itolizumab for management of moderate to severe plaque psoriasis. Expert opinion: The use of biologics to attenuate the immune-mediated pathological events in psoriasis is a relatively well-established clinical practice. However, the safety and efficacy of biologics continues to be an unsettled topic of ongoing research. While available data seems to suggest that itolizumab may be a safer option, additional studies with higher sample sizes and active comparators are needed before definitive conclusions can be drawn on the place of itolizumab in the management of psoriasis.
