June 16, 2026 updated by: Avant Health LLC

Patient and Clinician Reported Outcomes Among Patients With Actinic Keratosis Receiving Tirbanibulin for Large fiEld Application on the Face, in U.S Clinical pRactice Settings: A Pilot Initiative (CLEAR)

The goal of this observational study is to learn about the effectiveness of tirbanibulin among adult subjects with actinic keratosis (AK) lesions in the face. The main question it aim to answer is:

How does tirbanibulin improve subject's overall appearance of the skin, improve how patient's skin looks, and improve patient's skin texture, in a 57-day observation period.

Participants already taking tirbanibulin as part of their regular medical care for AK will answer online survey questions at the beginning of the study and at Day 57.
