E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Signed and dated written informed consent. 2. Men and women aged between 18 and 85 years inclusive suffering from actinic keratosis grade I or II. 3. Have a general good and stable health condition as confirmed by a physical examination and by medical history. 4. Patients with clinically stable medical conditions including, but not limited to the following diseases will be allowed to be included into the study, if the medication taken for the treatment of the disease does not match the criteria of the excluded or disallowed medications listed in points 7, 8, 9, 10, 11, 12 and 13 of the exclusion criteria: - controlled hypertension - diabetes mellitus type II - hypercholesterolaemia - osteoarthritis 5. Skin type I to IV according to Fitzpatrick. 6. Accept to abstain from sunbathing and the solarium during the study. 7. Have at least 4 but not more than 10 clinically confirmed AK target lesions of mild to moderate intensity within the face/forehead or bald scalp (excluding eyelids, lips and mucosa), i. e. actinic keratosis grade I and II according to Olsen EA et al. 1991. To document the diagnosis of the investigators, the AK-lesions will be photo-documented. 8. The AK lesions must be discrete and quantifiable; the distance from one lesion to its neighbour lesion is greater than 1.0 cm. 9. The diameter of each AK lesion is not less than 0.5 cm and not greater than 1.5 cm. Record the size of each baseline AK lesion by measuring the two largest perpendicular diameters. To describe irregular lesions (ellipsoidal) investigators will measure the major and minor axis. Both axes must be above the minimum of 0.5 cm and under the maximum of 1.5 cm. 10. The whole area to be treated (test area) must not be greater than 25 scm. Quantity of lesions to be treated must be adapted accordingly. 11. Are free of any significant physical abnormalities (e.g., tattoos, dermatoses) in the potential treatment area that may cause difficulty with examination or final evaluation. 12. Are willing to stop using moisturizers and any other topical treatments with anti-aging products, vitamin A, vitamin C, and/or vitamin E containing ointments and gels, and green tea preparations during the study within the treatment area. Sunscreens not containing vitamin E will be allowed, but should not be applied in the treatment area within approximately 24 hours before a clinical visit with lesion count. 13. Physical ability to apply the study preparations correctly and to follow the study restrictions and visit. 14. Women of childbearing potential are allowed to participate in this study, only if they use a highly effective method of contraception. A female is considered to be of childbearing potential if she possesses an uterus and at least one ovary, has not had a tubal ligation, or she is not at least 3 years postmenopausal. Highly effective methods of birth control are defined as resulting in a low failure rate (Pearl Index below 1, failure rate less than 1% per year) when used consistently and correctly such as implants, injectables, combined oral contraceptives, some IUDs, sexual abstinence or vasectomised partner. The use of condoms without spermicide coating is not considered to be a highly effective method of contraception.
