In this episode of Derms and Conditions, our host, James Q. Del Rosso, DO, interviews April Armstrong, MD, MPH, a professor and Chief of Dermatology at UCLA, about the development of tapinarof, a novel nonsteroidal topical treatment for psoriasis. 

They begin by discussing Dr Armstrong’s history of professional interest in psoriasis. The conversation then moves to focus solely on tapinarof, a topical cream that works by modulating the aryl hydrocarbon receptor (AhR). 

Dr Armstrong explains the unique mechanism of action of tapinarof and its effects on Th17 cytokines, antioxidant activity, and skin barrier function. She also discusses the efficacy demonstrated in clinical trials, with nearly 40% of patients achieving PASI 75 after 12 weeks, as well as the remittive effect in maintaining clear or almost clear skin. 

They address the safety profile of tapinarof, including the occurrence of folliculitis and contact irritation, and provide tips for its use in clinical practice. Dr Armstrong also emphasizes its versatility and potential as a combination therapy with systemic medications. All in all, the episode provides listeners with an expansive understanding of tapinarof as an effective and well-tolerated nonsteroidal treatment for plaque psoriasis.
