37The purpose of this study is to determine if the new vehicle formulations containing ingenol mebutate are as safe and effective as Picato® gel 0.05% (it's current vehicle formulation) when applied to AK lesions on the forearm for two consecutive days.
This study will be run in 2 parts. The first part involves applying escalating concentrations of the new vehicle formulations containing ingenol mebutate to AKs on the forearms. Reactions and safety will be compared to Picato® (a registered and marketed ingenol mebutate gel) to ascertain if the new vehicle formulations are at least as safe and effective as Picato® . The purpose of part 2 is to select the concentration in the "new formulation" that produces this same, if not better response, as Picato® and with a similar or better safety profile.
