Outcome Measures
Primary Outcomes (2)
Part 1: Number of Participants Experiencing a Dose-limiting Toxicity (DLT)
The number participants experiencing a DLT was used to identify the maximum tolerated dose (MTD) of LEO 43204 after once daily treatment for 2 consecutive days.The MTD was defined as the highest dose level with less than 4 out of 12 participants experiencing a DLT. A DLT was defined as: * Erosion/ulceration Grade 4 on the Local Skin Response (LSR) scale * Other clinically relevant signs or symptoms observed, which the International Co-ordinating Investigator judges to be counted as a DLT. The Local Skin Responses consists of the following 6 categories: Erythema, flaking/scaling, crusting, swelling, vesiculation/pustulation, erosion/ulceration. Each individual LSR category are given a numeric grade of severity from 0-4. Grade 0 being no presence and Grade 4 being the highest grade of severity.
From Day 1 up to and including Day 8
Part 2: Percent Reduction From Baseline in Actinic Keratosis (AK) Lesion Count
Percent reduction from baseline in clinically visible actinic keratosis lesions (AKs) in the selected treatment area.
From baseline to Week 8

Eligibility Criteria
You may qualify if:
- Part 1: Subjects with 5 to 20 clinically typical, visible and discrete AKs on the full balding scalp.
- Part 2: Subjects with 5 to 20 clinically typical, visible and discrete AKs on the full balding scalp
You may not qualify if:
- Location of the treatment area
- within 5 cm of an incompletely healed wound
- within 5 cm of a suspected basal cell carcinoma (BCC) or squamous cell carcinoma (SCC)
- Prior treatment with ingenol mebutate gel on the treatment area
- Lesions in the treatment areas that have
- atypical clinical appearance (e.g., hypertrophic, hyperkeratotic or cutaneous horns) and/or
- recalcitrant disease (e.g., did not respond to cryotherapy on two previous occasions)
