简要总结
Background: 5% 5-fluorouracil cream (5-FU) is a well-established treatment for actinic keratosis (AK) and ingenol mebutate gel (IMB) is a new topical field therapy.
Objective: To compare tolerability and safety of IMB with 5-FU for the treatment of facial AKs.
Methods: Open-label, prospective, randomized, controlled clinical trial with 100 patients with AKs within 25-cm2 contiguous field on the face. IMB was applied daily for three consecutive days. 5-FU was applied twice a day for four weeks. Treatment effect was evaluated at baseline and on days 2, 3, 4, 8, 15, 22, 29, 36 and 43, considering ITT populations.

入选标准
- •age of at least 18 years
- •the presence of four to eight clinically typical, visible, and discrete AKs within 25-cm2 contiguous field on the face (cheek or forehead region)
- •Women with childbearing potential had to be using effective birth control and have a confirmed negative urine pregnancy test prior to trial treatment.
排除标准
- •target treatment area was within 5 cm of an incompletely healed wound or within 10 cm of a suspected basal-cell or squamous-cell carcinoma
- •if they have received previous treatment with ingenol mebutate gel on the face or scalp (previous treatment on trunk or extremities was acceptable)
- •the selected treatment area had hyperkeratotic lesions or cutaneous horns and recalcitrant disease (lesions that had not responded to cryotherapy on two previous occasions)
- •history or evidence of skin conditions that would interfere with the evaluation of the trial medication (e.g., eczema, unstable psoriasis, xeroderma pigmentosum)
- •anticipated need for hospitalization or outpatient surgery during the first 15 days after the first trial medication application
- •known sensitivity or allergy to any of the ingredients of ingenol mebutate gel or 5-FU
- •presence of sunburn within of the target treatment area; current enrolment or participation in any other interventional clinical trial within 30 days of entry into this trial
- •women breastfeeding
- •recent use of medications or other treatments that could interfere with evaluation of the target area, such as topical medications (e.g. steroids, keratolytics, immunomodulators), artificial tanners, immunomodulators, cytotoxic drugs or interferon /interferon inducers, phototherapy, systemic retinoids, biologic/monoclonal antibody drugs, or other therapies for AKs within eight weeks prior to the first visit of the trial.
研究组 & 干预措施
ingenol mebutate
Patients assigned to ingenol mebutate gel received an application a day for three consecutive days in a pre-determined area
干预措施: ingenol mebutate (Drug)

Patients assigned to 5% 5-FU received two applications a day for four weeks in a pre-determined area
干预措施: 5% 5-FU (Drug)
结局指标
主要结局
Area under the LSR (local skin reactions)-Time Curve (AUC 0-43 days)
时间窗: Baseline and on day 43
Primary endpoint was to compare the total local skin reaction grading scale (LSR) and the area under the curve (AUC) with respect to duration of effects, using a generalized linear model, assuming a logarithmic link function. Age, Fitzpatrick skin type and site of the treatment were considered as covariates. The scale ranged from 0 to 4 (with higher numbers indicating greater severity) for the following six local skin effects: erythema, flaking/scaling, crusting, swelling, vesiculation/pustulation, and erosion/ulceration (maximum score of 24).
次要结局
- Area Under the each component of the total LSR-Time Curve (AUC 0-43 days)(Baseline and on day 43)
