Study Endpoints
Primary Endpoints
The primary endpoint will be inflammatory response or superficial effect at challenge period. Inflammatory responses (erythema and local skin reactions) or superficial effects (if observed) will be scored according to the grading scales.
Day 44 - 65

In cases where the patch area is larger than the irradiated area, only the irradiated areas will be scored unless reactions outside the irradiated area exhibit unusual responses. Scores represent the presence of clinically significant effects on at least 25% of the test site. Questionable, barely perceptible, or minimal reactions involving less than 25% of the test site will not be considered significant.
