Study to find out if cream V61-044 used to treat fungal infections causes an allergic skin reaction to sunlight in healthy participants
Allergic skin reaction can be produced by the combination of a chemical product applied to the skin and ultraviolet (UV) radiation (a type of invisible light that comes from the sun and other light sources and can hurt your skin and eyes) received by the person. The researchers in this study wanted to find out if cream V61-044 might cause an allergic skin reaction to sunlight when applied to the skin in healthy participants. Cream V61-044 (brand name: LOTRIMIN ULTRA) is an approved drug used to treat infections caused by fungi (small growing organisms such as mold, mildew, yeast or mushrooms).
Participants joining this study underwent two study phases: in Induction phase, participants received the test cream and UV radiation twice a week for 3 weeks; after 10 days of rest, in Challenge phase participants received the test cream and UV radiation once again. In both phases, the test cream was applied to two test areas on the upper back of the participants and to one of the test area UV radiation was applied. Evaluation on the skin rash was conducted two days after each UV radiation.
