What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants With Complete (100%) Clearance of Actinic Keratosis (AK) Lesions
Time Frame: Day 57
|
Complete clearance rate was defined as the percentage of participants at Day 57 with no clinically visible AK lesions in the treatment area.
|
Day 57
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants With Partial Clearance Rate of Actinic Keratosis Lesions at Day 57
Time Frame: Day 57
|
Partial clearance rate of AK lesions was defined as the percentage of participants with a greater than or equal to (>=) 75% reduction in the number of AK lesions identified at Baseline (Day 1 predose) in the treatment area.
|
Day 57
|
Overall Change From Baseline in Actinic Keratosis Lesion Counts at Days 8, 15, 29 and 57
Time Frame: Days 8, 15, 29 and 57
|
Overall the change from baseline in lesion count at each visit were summarized and reported using descriptive statistics by treatment location (face or scalp).
|
Days 8, 15, 29 and 57
|
Percentage of Participants With Recurrence of Actinic Keratosis Lesions Who Achieved Complete Clearance at Day 57
Time Frame: 3, 6, 9 and 12 months post-Day 57
|
Recurrence rate was estimated based on Kaplan-Meier method, with recurrence define as appearance of any AK lesions in the treatment area, including those recurred or newly identified.
|

|
Number of Participants With Maximal Post Baseline Local Skin Reaction (LSR)
Time Frame: Day 57
|
Maximal post baseline LSR was defined as the highest grade of any LSR reported at any post baseline visits for a participant.
The LSR assessment was an Investigator's (or sub-investigator's) assessment of the following signs on the treatment area: erythema, flaking/scaling, crusting, swelling, vesiculation/pustulation, and erosion/ulceration.
The LSRs were graded on a 4-point scale ranging from 0=absent, 1=mild (slightly, barely perceptible), 2=moderate (distinct presence), and 3=severe (marked, intense).
|
Day 57
|

TEAEs (serious and non-serious) were defined as either those AEs with onset after first dose or those pre-existing AEs that worsen after first dose.
Events of special interest included skin cancers (including basal cell carcinoma, squamous cell carcinoma, melanoma and their location and treatment area), ocular exposure, overdose, and pregnancy.
