Experimental: Tirbanibulin (Klisyri®) Participants will apply tirbanibulin ointment 1% once daily for 5 days beginning Day 1. Participants will be evaluated for safety, tolerability, and the presence of AK lesions in the treatment field (TF) until completion of the response assessment period at Day 57 |
Drug: Tirbanibulin ointment 1%
Participants will apply Tirbanibulin ointment 1% topically for 5 days over a field of approximately 100 cm^2 on the face or balding scalp with Actinic Keratosis (AK).

Outcome Measures
Primary Outcome Measures
- Local Tolerability Score for Signs Including Erythema, Flaking/Scaling, Crusting, Swelling, Vesiculation/Pustulation, and Erosion/Ulceration [Up to Day 57]
Local tolerability score is evaluated by investigator in terms of presence and absence of erythema, flaking/scaling, crusting, swelling, vesiculation/pustulation, and erosion/ulceration signs and its severity in the areas of body where medication is applied. These symptoms are assessed by using a 4 - point scale of 0 - 3, where 0 = none and 3 = severe. The higher score indicates severe symptoms.
- Change from Baseline in Maximum Local Tolerability Score [Baseline to up to Day 57]
Change from baseline in maximum local tolerability score will be assessed for erythema, flaking/scaling, crusting, swelling, vesiculation/pustulation, and erosion/ulceration. Local tolerability score for each signs are assessed by using a 4 - point scale of 0 - 3, where 0 = none and 3 = severe.
- Time to Maximum Local Tolerability Score for Erythema, Flaking/Scaling, Crusting, Swelling, Vesiculation/Pustulation, and Erosion/Ulceration [Baseline up to Day 57]
Time to maximum local tolerability score for erythema, flaking/scaling, crusting, swelling, vesiculation/pustulation, and erosion/ulceration will be assessed. The higher score indicates severe symptoms.
- Local Tolerability Signs Composite Score [Baseline up to Day 57]
Local tolerability signs composite score (0-18) by visit, defined as the sum of the scores graded from 0 to 3 on all six individual tolerability sign categories - erythema, flaking/scaling, crusting, swelling, vesiculation/pustulation, and erosion/ulceration.
- Change From Baseline in Maximum Local Tolerability Signs Composite Score [Baseline up to Day 57]
Change from baseline in maximum local tolerability signs composite score will be assessed for erythema, flaking/scaling, crusting, swelling, vesiculation/pustulation, and erosion/ulceration.
- Time to Maximum Local Tolerability Composite Score [Baseline up to Day 57]
Time to maximum local tolerability composite score for erythema, flaking/scaling, crusting, swelling, vesiculation/pustulation, and erosion/ulceration will be assessed.
- Number of Participants with change from baseline in hypopigmentation in treatment field [Baseline up to Day 57]
Number of participants with change from baseline in hypopigmentation in the treatment area will be assessed.
- Number of Participants with change from baseline in hyperpigmentation in treatment field [Baseline up to Day 57]
Number of participants with change from baseline in hyperpigmentation in the treatment area will be assessed.
- Number of Participants with change from baseline in Scarring in treatment field [Baseline up to Day 57]
Number of participants with change from baseline in scarring in the treatment area will be assessed.
- Number of Participants With Any Treatment-emergent Adverse Events [Baseline up to Day 57]
An Adverse Event (AE) is defined as any untoward medical occurrence in a participant or clinical investigation participant administered an Investigational Product. An AE did not necessarily have a causal relationship with the medicinal product. Treatment-emergent Adverse Events (TEAEs) were defined as either those AEs with an onset after dosing or those pre-existing conditions that worsened after dosing. TEAEs included both serious and non-serious TEAEs.
- Number of Participants With Any Treatment-emergent Serious Adverse Events [Baseline to up to Day 57]
A Serious Adverse Event (SAE) is defined as any untoward medical occurrence that at any dose, resulted in death, was life-threatening (i.e, the participant was at immediate risk of death from the AE as it occurred; this did not include an event that, had it occurred in a more severe form or was allowed to continue, might have caused death), required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect (in the child of a participant who was exposed to the study drug).
- Number of Participants With Clinically Significant Laboratory Abnormalities [Up to Day 57]
Number of participants with clinically significant laboratory parameters (included hematology, blood chemistry and urinalysis) will be assessed.
- Number of Participants With Vital Signs Abnormalities [Up to Day 57]
Number of participants with vital signs (included measurement of pulse rate, systolic and diastolic blood pressure, respiratory rate, and body temperature) will be reported
- Number of Participants With Physical Examination Abnormalities [Up to Day 57]
Number of participants with physical examination abnormalities (weight and height) measurements will be reported.
- Number of Participants With Electrocardiograms (ECGs) Abnormalities [Up to Day 57]
Number of participants with ECG (heart rhythm, heart rate, QRS intervals, QT intervals, RR intervals and corrected QT (QTc) intervals) abnormalities will be reported.
