Brief Summary in Lay Language

In this study the impact of Oleogel-S-10 versus placebo on actinic keratoses over a
treatment period of 3 months will be tested. Additionally, once and twice daily applications
are tested.

Brief Summary in Scientific Language

Oleogel-S-10 has shown efficacy and was well tolerated in two previous clinical trials. In
the second open label phase II trial the efficacy of Oleogel-S-10 alone was similar compared
to a more invasive treatment with cryotherapy. Response rates of 85% with a clear-ance of
more than 75 % of the lesions of the patients treated with Oleogel-S-10 over three months
were reported. These encouraging results led to the present randomized, multicenter, double
blind phase II trial. The efficacy of the treatment shall be tested in a double blind
placebo controlled (petroleum jelly) fashion in order to obtain more reliable results for
the planning of a phase III study.

Primary Outcome

- Objective response of the marker actinic keratosis, defined as histologically complete or partial clearance.; time frame: 18 weeks; Objective response of the marker actinic keratosis, defined as his-tologically complete or partial clearance (partial clearance = down-grading in Cockerell-classification). The marker actinic keratosis is defined as an initially selected lesion within the target area that will be used for final biopsy.

start of 1:1-Block exclusion criteria

Exclusion Criteria

- Active immunosuppressive therapy

- data of clinically significant, unstable, cardiovascular or hematologic, hepatic,
neurologic, renal, endocrine, collagen-vascular, or gastrointestinal abnormalities or
diseases Note: Patients with clinically stable medical conditions including, but not
limited to, controlled hypertension, diabetes mellitus type II, hypercholesterolemia,
or osteoarthritis will be allowed to enter the study

- known allergies to any excipient in the study drug

- any dermatological disease and/or condition in the treatment or surrounding area (3
cm distances from treatment area) that may be exacerbated by treatment with
Oleogel-S-10 or cause difficulty with examination

- active chemical dependency or alcoholism, as assessed by the investigator

- pregnant and lactating women

- currently participating in another clinical study or have completed another clinical
study with an investigational drug within the past 30 days

- received topical treatment at the treatment area with diclofenac gel, imiquimod or
5-FU within a time period of 1 month

- Concomitant existence of non-treated (non-excised) basal cell carcinoma, squamous
cell carcinoma or malignant melanoma

- Invasive tumors within the treatment area, e.g.: merkel cell carcinoma, squamous cell
carcinoma, basal cell carcinoma, the latter is accepted if completely surgically
removed Note: A biopsy of any lesion within the treatment or surrounding area
suggestive of malignancy should be performed at the pre-study screening visit. If
invasive SCC or other malignant conditions are confirmed within the treatment area,
the patient will not be included in the study.
