Treatment Arms

ArmTypeDescription
Tapinarof Drug TreatmentEXPERIMENTALSubjects in this arm will apply Tapinarof 1% cream topically once daily for a 16-week open-label treatment period. Participants who achieve disease clearance after 16 weeks may discontinue treatment and will be monitored for sustained response up to 52 weeks. Those who do not achieve clearance will continue the treatment during an extension period for up to 36 additional weeks or until clearance is achieved, whichever comes first. Regular follow-up visits will assess the duration of disease clearance and monitor for any potential recurrence of keratoderma.
