Primary Outcome Measures
NameTimeMethod
Incidence of AEs Recorded Throughout the Study57 days

Incidence of AEs recorded throughout the study

Incidence of SAE Recorded Throughout the Study57 days

Incidence of SAE recorded throughout the study

Incidence of Hyperpigmentation Following Study Medication ApplicationDay 57

The selected treatment area was assessed for hyperpigmentation at baseline (Day 1 pre-dose), Day 57, and at each poststudy followup visit as warranted. If any pigmentation was present, the significance and extent of pigmentation and scarring was recorded. At all timepoints, pigmentation evaluations were performed by a board certified Dermatologist (or equivalent)

Incidence of Hypopigmentation Following Study Medication ApplicationDay 57

The selected treatment area was assessed for hypopigmentation at baseline (Day 1 pre-dose), Day 57, and at each poststudy followup visit as warranted. If any pigmentation was present, the significance and extent of pigmentation and scarring was recorded. At all timepoints, pigmentation evaluations were performed by a board certified Dermatologist (or equivalent)

Incidence Rate and Severity of LSRs Following Study Medication ApplicationDay 57

The treatment area was assessed at baseline, Day 1 (pre-dose), and at each subsequent study visit for the presence and grade (0 to 4) of the following LSRs: erythema; flaking/scaling, crusting, swelling, vesiculation/pustulation, and erosion/ulceration. A composite LSR score (0 to 24), reflecting the sum of each individual LSR grade, was calculated for each patient at each visit.

The actual value and change from baseline in the composite LSR score were also summarized.

Incidence of Scarring Following Study Medication ApplicationDay 57

The selected treatment area was assessed for scarring at baseline (Day 1 pre-dose), Day 57, and at each poststudy followup visit as warranted. If any scarring was present, the significance and extent of scarring was recorded. At all timepoints, pigmentation evaluations were performed by a board certified Dermatologist (or equivalent).

Complete Clearance Rate of AK Lesions;Day 57

Defined as the number of patients at the day 57 post-treatment visit with no clinically visible AK lesions in the selected treatment area

Secondary Outcome Measures
NameTimeMethod
