Tapinarof for psoriasis and atopic dermatitis

March 17th, 2021 | General Info

tapinarof for psoriasis and atopic dermatitis

Tapinarof is an investigational drug that is being studied for the treatment of psoriasis and atopic dermatitis. It is a topical aryl hydrocarbon receptor (AhR)-modulating agent. Tapinarof binds and activates AhR, which leads to downregulation of inflammatory cytokines such as interlukin 17.

Phase 2 clinical studies with a topical cream showed improvement in psoriasis after two weeks of cream with maintenance of improvement for 4 weeks after treatment discontinuation.

This prompted a phase 3 clinical trial for psoriasis using tapinarof 1% cream applied once daily. We are now awaiting the results of the randomized controlled trials.

A phase 2b study published in the Journal of the American Academy of Dermatology on the effectiveness of tapinarof on atopic dermatitis showed good improvement following use of topical 1% cream.
