简要总结
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

入选标准
- •Signed Informed Consent Form (ICF) prior to any trial-related procedures
- •Subjects with 5 to 9 clinically typical, visible and discrete AKs within a contiguous 25 cm² treatment area on the face or scalp.
- •Subject at least 18 years of age
- •Female subjects must be of either:
- •Non-childbearing potential, or,
- •Childbearing potential, provided there is a confirmed negative urine pregnancy test
- •Female subjects of childbearing potential must be willing to use highly effective methods of contraception (Pearl index < 1%)
排除标准
- •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
- •Selected treatment area lesions that have atypical clinical appearance (e.g., hypertrophic, hyperkeratotic or cutaneous horn).
- •History of SCC, BCC, malignant melanoma or other neoplasia in the selected treatment area.
- •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
- •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)
- •Organ transplant recipients
- •Immunosuppressed subjects (for example HIV patients)
- •Female subjects who are breastfeeding.
- •Subjects who are institutionalised by court order or by the local authority
- •In the opinion of the investigator, the subject is unlikely to comply with the Clinical Study Protocol (e.g. alcoholism, drug dependency or psychotic state)
研究组 & 干预措施
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
干预措施: Ingenol Mebutate Gel, 0.015% (Drug)
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
干预措施: Imiquimod Cream, 5% (Drug)
结局指标
主要结局
Incidence of SCC
时间窗: 3 years
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.\> Kaplan-Meier estimate based on time to SCC or censoring.
次要结局
- Incidence of SCC and Other Neoplasia(3 years)
- Number of Participants With Partial Clearance of AK Lesions(8-16 weeks)
- Number of Participants With Complete Clearance of AK Lesions After Last Treatment(8-16 weeks)
- Number of Participants With Complete Clearance of AK Lesions at 12 Months(1 year)
