Brief Summary

The objective of this study was to evaluate the safety and therapeutic equivalence of generic ingenol mebutate gel, 0.015% to Picato gel, 0.015% by establishing the therapeutic comparability of the two active products and the superiority of the two active products over the vehicle gel in the treatment of AK on the face and scalp.

Detailed Description

Picato® (ingenol mebutate) gel is the first and only ingenol mebutate product approved by the Food and Drug Administration (FDA) in 2012 for the topical treatment of AKs on the face and scalp (0.015% formulation) and on the trunk and extremities (0.05% formulation). The FDA approved regimen for ingenol mebutate gel, 0.015% for the treatment of AKs on the face and scalp is once-daily application of one unit dose tube for three consecutive days applied to one contiguous skin area of approximately 25 cm2 (e.g., 5 cm x 5 cm).

• Subject provided written informed consent.
• Subject had a clinical diagnosis of AK at Visit 1/Baseline with at least four, but no more than eight visible and discrete non-hyperkeratotic, non-hypertrophic AK lesions, each at least 4 mm in diameter, within a contiguous 25 cm2 treatment area ("the Treatment Area") located on the face or scalp.
• Subject was willing and able to apply the test article as directed, comply with study instructions, and commit to all follow-up visits for the duration of the study.
• Subject was in good general health and free of any disease state or physical condition that might have impaired evaluation of AK lesions or which, in the investigator's opinion, exposed the subject to an unacceptable risk by study participation.

Exclusion Criteria

• 1. Subject was pregnant, lactating, or was planning to become pregnant during the study.
• Subject had a location of the selected contiguous 25 cm2 Treatment Area that (a) was within 5 cm of an incompletely healed wound or (b) was in an area containing a lesion that was previously treated with ingenol mebutate.
• Subject had hyperkeratotic, hypertrophic, or large mat-like AKs (e.g., AK >1 cm2 in size) within the contiguous 25 cm2 Treatment Area.
• Subject had more than eight AKs, independent of size, within the selected contiguous 25 cm2 Treatment Area
• Subject had atopic dermatitis, basal cell carcinoma, eczema, psoriasis, rosacea, squamous cell carcinoma, xeroderma pigmentosum, or any other possibly confounding skin conditions within the region of the head that contained the selected Treatment Area (i.e., face or scalp).
• Subject had any skin pathology or condition that, in the investigator's opinion, could have interfered with the evaluation of the test article or required the use of interfering topical, systemic, or surgical therapy.
• Subject was immunosuppressed (e.g., human immunodeficiency virus, systemic malignancy, graft host disease, etc.).
• Subject experienced an unsuccessful outcome from previous ingenol mebutate therapy (an unsuccessful outcome was defined as after a reasonable therapeutic trial with no compliance issues and the topical drug did not work).
• Subject used topical creams, lotions, or gels of any kind within the selected Treatment Area within one day prior to entry into the study.
• Subject had the need or planned to be exposed to artificial tanning devices or excessive sunlight during the study or had used artificial tanners within two weeks of Visit 1/Baseline.
• Subject had used any of the following topical medications on the face or scalp:

• Corticosteroids within two weeks of Visit 1/Baseline;
• Keratolytic-containing therapeutic products or medicated or irritant topical salves within two weeks of Visit 1/Baseline, including, but not limited to, alpha hydroxy acids (e.g., glycolic acid, lactic acid etc. >5%), beta hydroxy acid (salicylic acid >2%), and urea >5%;

• 5-fluorouracil, diclofenac, imiquimod, or ingenol mebutate within eight weeks of Visit 1/Baseline; or
• Other topical therapy for actinic keratosis within 2 cm of the selected contiguous 25 cm2 Treatment Area within eight weeks of Visit 1/Baseline.
• Subject had cryodestruction or chemodestruction, surgical excision, curettage, dermabrasion, chemical peel, or laser resurfacing on the Treatment Area (i.e., face or scalp) within two weeks prior to Visit 1/Baseline.

• Subject was enrolled in an investigational drug or device study.
• Subject used an investigational drug or investigational device treatment within one month prior to Visit 1/Baseline.
• Subject had a history of sensitivity to any of the ingredients in the test articles (see Section 9.4.2).
• Subject had any condition which, in the investigator's opinion, would have made it unsafe or precluded the subject's ability to fully participate in this research study.
