A baseline evaluation of the patch sites will be performed immediately prior to application of the patches to ensure that no conditions, markings, or coloration of the skin will interfere with interpretation of the study results.~A total of 4 application sites (2 cm x 2 cm each) will be marked on each subject's back, placing 2 sites for KX01KX2-391 ointment 1% and 2 sites for Placebo vehicle ointment. One set (KX01 ointment 1% IP and Placebo ointment vehicle patches) will be designated for irradiation and the other set will remain non-irradiated under open conditions. The distance between the patches will be no less than one centimeter.~The numbering of the test sites will remain the same throughout the study. The sites will be marked with an indelible, surgical marker.
