Clinical Context
Plaque psoriasis is a chronic autoimmune skin disorder characterized by the rapid proliferation of skin cells, leading to thick, scaly patches on the skin. This condition affects approximately 2-3% of the global population and can significantly impair quality of life due to associated symptoms such as itching, discomfort, and psychological distress. Current treatments include topical agents, phototherapy, and systemic therapies, including biologics targeting IL-23, IL-17, and TNF pathways. Despite these options, many patients remain inadequately controlled, highlighting the need for new therapies that can provide effective and convenient treatment. The recent approval of deucravacitinib, an oral selective tyrosine kinase 2 (TYK2) inhibitor, and tapinarof, a topical aryl hydrocarbon receptor modulating agent, offers promising alternatives for patients with moderate to severe plaque psoriasis, particularly those who may not respond to existing treatments.
