Exclusion criteria
Exclusion criteria: 1.

Note: Patients with clinically stable medical conditions including, but not limited to, controlled hypertension, diabetes mellitus type II, hypercholesterolaemia, or osteoarthritis will be allowed to enter the study. Have asthma or active gastrointestinal ulceration/bleeding. 2. Have any dermatological disease and or condition in the observation area or in the surrounding area (3cm distance from observation area) that may be exacerbated by treatment with Solaraze® gel or cause difficulty with examination (eg, rosacea, psoriasis, atopic dermatitis, eczema). 3.

Have received any treatment at the observation area within a time period of 2 months. 8. Have invasive tumors within the observation area (eg., squamous cell carcinoma). Note: A biopsy of any lesion within the observation area suggestive of malignancy should be performed. If squamous cell carcinoma or other malignant conditions are confirmed within the observation area, the patient will not be included in the study. 9. Have received any cancer chemotherapy, or radiation therapy, within 6 months prior to study treatment initiation (patient must not have any evidence of systemic cancer). 10.

Have received ?15000 units per day of Vitamine A or derivates within 2 weeks prior to study treatment initiation. 13. Have used any topical preparations, such as over-the-counter retinol products, moisturizers, sunscreens or body oils, or alpha or beta hydroxyacids in the observation area within 24 hours prior to the visit. 14. Have used sunscreen in the observation area within a minimum of approximately 24 hours prior to study treatment initiation. 15.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Assessment of the modulation of key factors involved in the pathophysiology of Actinic Keratosis by Solaraze. Comparison of levels of expression of the chosen factors between active treatment and no treatment. ;Secondary Objective: Efficacy will be measured by comparing target lesion number score (TLNS) and cumulative lesion number score (CLNS) at baseline to the end of study timepoint. Safety will be monitored throughout the study. ;Primary end point(s): Assessment of the modulation of key factors involved in the pathophysiology of Actinic Keratosis by Solaraze. Comparison of levels of expression of the chosen factors between active treatment and no treatment. | — |
