Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Actinic Keratoses Drug: Oleogel-S10 100 mg/g Drug: Placebo (petroleum jelly) Phase 2

Detailed Description:
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 Measures :
  1. 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 histologically 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.

    The Cockerell classification refers to a single lesion, graded as the presence of atypical cells in the lower third of the epidermis (grade I), involvement of at least the lower two-thirds (grade II) or atypical keratinocytic proliferation in the entire epidermis (grade III). Thus a down-grading from a higher Cockerell grade (e.g., III) to a lower Cockerell grade (e.g., I) represents a positive outcome and treatment success.

    • application of Oleogel-S10 on the treatment area once or twice a day
    • 4 clinic visits during the pre-study, treatment, post-treatment, and follow-up period
    • pre- and post-treatment biopsy for histological confirmation (of clearance) of AK-diagnosis
  • Representative histologic slide and tissue block were shipped

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

  • 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.
