  • Women who have had surgical sterilization or are post-menopausal (absence of menses for at least one year) are eligible. Women of child-bearing potential who are non-pregnant and non-nursing, and willing to avoid pregnancy during the course of the study and during the menstrual cycle following completion of their participation in the study are eligible.

  • Considered reliable and capable of understanding their responsibility and role in the study
  • Have provided written informed consent

Exclusion Criteria:

  • History of allergy or hypersensitivity to 5-fluorouracil

    • Known dihydropyrimidine dehydrogenase (DPD) enzyme deficiency
    • More than 10 lesions total on the face (Lesions that are hyperkeratotic, thicker than 1 mm (a piece of paper) or larger than 9 mm, or lesions suspicious for squamous cell carcinoma will not be included in lesion counts.)
    • Clinical evidence of severe, uncontrolled auto-immune, cardiovascular, gastrointestinal, hematological, hepatic, neurological, pancreatic, pulmonary or renal disease
    • Dermatologic conditions if present on the face such as: atopic dermatitis, basal cell carcinoma, eczema, psoriasis, rosacea, squamous cell carcinoma, or albinism
    • Positive urine pregnancy test in women of child-bearing potential
    • Inability to use adequate birth control measures for women of child-bearing potential, as defined above
    • Serious psychological illness
    • Significant history (within the past year) of alcohol or drug abuse
    • Participation in any clinical research study during the 30 day period preceding study initiation
    • Medical history which, based on the clinical judgment of the investigator, implies an unlikelihood of successful completion of the study
    • Treatment for actinic keratosis or skin cancer in the previous 28 days with the following: topical 5 fluorouracil, cryodestruction (liquid nitrogen spray), curettage (scraping of pre-cancer or skin cancers), surgical removal of skin cancer, photodynamic therapy, surgical excision, topical diclofenac (Solaraze), topical imiquimod (Aldara), topical retinoids if used for actinic keratosis or other treatments for actinic keratoses
    • Application of 1) chemical peel, 2) dermabrasion, 3) laser abrasion, 4) PUVA (psoralen plus ultraviolet A) therapy, or 5) UVB therapy to the face or bald scalp within six months prior to randomization
    • Use of sun lamps or sun tanning beds or booths during the 2 weeks prior to first application until Day 42 visit
    • Any oral (systemic steroids) or topical corticosteroids within 1 month of study entry, except for subjects on chronic low dose corticosteroids less than 5 mg daily for greater than 1 year
    • Use within 1 month of any immunomodulators like interferon, or cytotoxic drugs
    • Prior treatment with systemic 5-fluorouracil or systemic cancer therapy within 6 months of study entry
    • Subjects with lesions suspicious for squamous cell carcinoma
