Imiquimod mouse psoriasis model: reduced epidermal thickness and IL-17a/IL-17f/IL-19/IL-1β/IL-23a mRNA
“In animal models, the anti-inflammatory activity of tapinarof has been demonstrated in the imiquimod mouse model of psoriasis. It led to reductions in epidermal thickness and mRNA expression of key pro-inflammatory cytokines (IL-17a, IL-17f, IL-19, IL-1β, and IL-23a).”

Why that model
Not stated in public reviews
Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.
Reviewer's view of the efficacy data
FDA: nonclinical data supported label mechanism statements, but several were of unclear relevance and removed
“Although the applicant provided nonclinical data to factually support statements made in section 12.1, several portions are of unclear relevance to the mechanism of action and should be removed.”
