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 Intervention Phase

Primary Outcome Measures:
  • Objective response of the marker actinic keratosis, defined as histologically complete or partial clearance. [ Time Frame: 18 weeks ] [ Designated as safety issue: Yes ]
    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.

Secondary Outcome Measures:
  • Histologically controlled complete clearance Histologically controlled downstaging 75 % clearance rate Dose response relationship Time to clinically complete response Tolerability [ Time Frame: 18 weeks ] [ Designated as safety issue: Yes ]

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.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • At least two mild to moderate actinic keratoses located at the facial skin or the head (except lips)
  • Actinic keratoses with a diameter of 0,5 - 2 cm,

    • that are definitely distinguished from other lesions and display a minimum distance of 0,5 cm to neighbored lesions
    • that are evaluated as histopathological grade 1 to 3
  • histologically proven AK within three months before study entry
  • prepared and able to give written informed consent
  • ≥ 18 years of age
  • In case of females: postmenopause defined as

    • natural menopause with menses > 1 year ago
    • serum FSH (> 20 IU/l) and E2 levels in the postmenopausal range or
    • patients who had bilateral oophorectomy
  • prepared and comply with all study requirements, including the following:

    • 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
  • 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.
