The purpose of the study is to compare the risk of developing squamous skin cancer (SCC) or other types of cancer after treatment of AKs with ingenol mebutate gel or imiquimod cream. Subjects will be randomised to treatment with ingenol mebutate or imiquimod and will receive a second treatment cycle with the same treatment if the first treatment does not clear all AKs. Subjects will be followed over a period of three year (36 months) after first treatment

Condition Intervention Phase
Actinic Keratosis (AK) Drug: Ingenol Mebutate Gel, 0.015% Drug: Imiquimod Cream, 5% Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 4 Trial Comparing the Cumulative Incidence of SCC After Treatment With Ingenol Mebutate and Imiquimod for Multiple Actinic Keratoses on Face and Scalp. A Multi-centre, Randomised, Two-arm, Open Label, Active-controlled, Parallel Group, 36-month Trial

Further study details as provided by LEO Pharma:

Primary Outcome Measures:
  • Incidence of SCC [ Time Frame: 3 years ]

    To compare the cumulative incidence of SCC after treatment with ingenol mebutate gel and imiquimod cream.

    The primary response criterion is diagnosis of SCC (defined as invasive SCC i.e. excludes SCC in situ) in the treatment field across the 3-year trial period.

Secondary Outcome Measures:
  • Incidence of neoplasia [ Time Frame: 12 months ]
    To compare the cumulative incidence of neoplasia and the short-term and 12-month efficacy of ingenol mebutate gel with imiquimod cream.

Enrollment: 579
Study Start Date: September 2013
Estimated Study Completion Date: June 2018
Estimated Primary Completion Date: June 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ingenol Mebutate
Arm A: Ingenol mebutate gel 0.015% applied daily for 3 consecutive days to the selected treatment area followed by 8 weeks' rest. Retreatment for another 3 consecutive days if the treatment field is not completely cleared of AKs at Week 8
Drug: Ingenol Mebutate Gel, 0.015%
Ingenol mebutate gel 0.015 % (Picato®) applied on the selected treatment area. Retreatment if the treatment field is not completely cleared of AKs.
Other Name: Picato®
Active Comparator: Imiquimod
Arm B: Imiquimod 5% cream applied 3 days per week for 4 weeks to the selected treatment area followed by 4 weeks' rest. Retreatment for another 4 weeks if the treatment field is not completely cleared of AKs at Week 8
Drug: Imiquimod Cream, 5%
Imiquimod 5% cream applied to the selected treatment area. Retreatment if the treatment field is not completely cleared of AKs
Other Name: Aldara®


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Signed Informed Consent Form (ICF) prior to any trial-related procedures
  2. Subjects with 5 to 9 clinically typical, visible and discrete AKs within a contiguous 25 cm² treatment area on the face or scalp.
  3. Subject at least 18 years of age
  4. Female subjects must be of either:

    1. Non-childbearing potential, or,
    2. Childbearing potential, provided there is a confirmed negative urine pregnancy test
  5. Female subjects of childbearing potential must be willing to use highly effective methods of contraception (Pearl index < 1%)

Exclusion Criteria:

  1. Location of the selected treatment area:

    • on the periorbital skin
    • on the perioral skin/around the nostrils
    • within 5 cm of an incompletely healed wound
    • within 10 cm of a suspected BCC or SCC or other neoplasia
  2. Selected treatment area lesions that have atypical clinical appearance (e.g., hypertrophic, hyperkeratotic or cutaneous horn).
  3. History of SCC, BCC, malignant melanoma or other neoplasia in the selected treatment area.
  4. History or evidence of skin conditions other than the trial indication that would interfere with evaluation of the trial medication in the selected treatment area
  5. Use of ingenol mebutate and/or imiquimod in and within 5 cm of the selected treatment area within 2 years prior to Screening (Visit 1)
  6. Organ transplant recipients
  7. Immunosuppressed subjects (for example HIV patients)
  8. Female subjects who are breastfeeding.
  9. Subjects who are institutionalised by court order or by the local authority
