Summary:
The objective of this study is to compare the relative efficacy and safety of the test
formulation Imiquimod 3.75% Topical Cream to the marketed formulation Zyclara® (imiquimod)
3.75% Topical Cream in the treatment of actinic keratosis. Both the test and reference
formulations will also be compared to a placebo cream to test for superiority.

- Signed informed consent form.
- Immunocompetent male or non-pregnant, non-lactating female at least 18 years of age.
- Diagnosis of actinic keratosis with at least 5 and no more than 20 clinically typical, visible or palpable actinic keratosis lesions, each at least 4 mm in diameter, in an area that exceeds 25 cm2 on either the face (excluding ear) or balding scalp (but not both.)
- Women either must be 1 year post-menopausal, surgically sterile, or if they are of child-bearing potential, they must: a) have been using systemic birth control, intrauterine device, or Norplant for at least 28 days prior to the start of treatment period, or used barrier methods consistently, at least 14 days before study cream administration; b) had a normal menstrual cycle for the month prior to the start of treatment; c) have a negative urine pregnancy test result upon entry into the study; d) agree to use a medically accepted form of birth control throughout the study period.
- Free from any systemic or dermatologic disorder that, in the opinion of the Investigator, will interfere with the study results or increase the risk of adverse events.
- Any skin type or race, providing the skin pigmentation will allow discernment of erythema.
- Willingness and capability to cooperate to the extent and degree required by the protocol.
Exclusion Criteria:
- Presence of atopic dermatitis, basal cell carcinoma, squamous cell carcinoma, eczema, psoriasis, rosacea, sunburn or other possible confounding skin conditions on the face or bald scalp.
- Use within six months prior to baseline on the face or bald scalp of chemical peel, dermabrasion, laser abrasion, psoralen plus ultraviolet A therapy, or ultra violet B therapy.
- Use within one month prior to baseline on the face or bald scalp of cryodestruction or chemodestruction, curettage, photodynamic therapy, surgical excision, topical 5-fluorouracil, topical corticosteroids, topical diclofenac, topical imiquimod, topical retinoids or other treatments for actinic keratosis including glycolic acids or over-the-counter products containing retinol, alpha or beta hydroxy acids.
- Use within one month prior to baseline of immunomodulators or immunosuppressive therapies, interferon, oral corticosteroids or cytotoxic drugs.
- Known allergies to imiquimod or any excipients to the test or reference creams.

- Any condition, medical, psychological, or social, that, in the Investigator's opinion, would interfere with participation in the study.

- Participation in any investigational drug study within 30 days of enrollment or previous participation in this study.
- Employees or family members of employees of the research center or Investigator.
Outcome:
Primary outcome
  • Treatment success
    Treatment success will be defined by the proportion of patients in the per protocol population with 100% clearance of all actinic keratosis lesions within the treatment area at study week 14 (8 weeks after completion of treatment.)
    Time frame: Week 14 (8 weeks after completion of treatment)
Secondary outcome
  • Superiority to placebo
    The modified intent-to-treat population and last observation carried forward will be used to evaluate the superiority of both the test and reference product to placebo for the proportion of patients showing 100% clearance of actinic keratosis lesions at week 14 (8 weeks after completion of treatment.)
    Time frame: Week 14 (8 weeks after completion of treatment)
