It affects an estimated 7.5 million people in the U.S. and approximately 125 million people worldwide 1. It is a non-contagious disorder that speeds the growth cycle of skin cells 1 and results in thick scaly areas of skin 2. The most common form of psoriasis, called plaque psoriasis, appears as red, raised areas of skin covered with flaky white scal es, which may be itchy and painful and can crack and bl eed 2. Despite existing treatment options, many people with plaque psoriasis continue to struggle w ith the ongoing, persistent nature of this chronic disease. About Tildrakizumab Tildrakizumab is an investigational humanized, anti -IL-23p19 monoclonal antibody designed to selectively block the cytokine IL-23. With this pre cise targeting, tildrakizumab has the potential to help control the pathogenic cells responsible for the inflammatory process of psoriasis with limited impact on the rest of the immune system. Phase-3 tildrakizuma b data provide further evidence for the role of the IL-23 pathway in helping to control the inflammatory process of psoriasis.
