Study to Find Out if Cream V61-044 Used to Treat Fungal Infections Causes an Allergic Skin Reaction to Sunlight in Healthy Participants

To each of two test sites, approximately 20 μl/cm\^2 of the Butenafine HCl 1% was applied directly to the skin and covered with a 25 mm Hilltop chamber with a Webril pad (2 cm in diameter, within an area of approximately 3 cm\^2), and tape was applied over the chamber to secure the occlusive patch to the skin. On the next day, the chambers were removed and both test sites were lightly wiped. Approximately 2 μl/cm\^2 of Butenafine HCl 1% was reapplied directly to the skin and lightly spread over the treated irradiated test site. The treated non-irradiated test site did not receive a similar reapplication. Between 5 and 15 minutes after application, the treated irradiated test site was irradiated with two times the subject's Minimal Erythema Dose (MED). Evaluation of the test sites occurred two days after the irradiation. This procedure was repeated two times per week for three consecutive weeks for a total of 6 induction exposures per test site.

5 μl/cm\^2 of the Butenafine HCl 1% was applied directly to each of the two virgin sites (treated sites) adjacent to the induction patch sites and covered with Hilltop chambers with Webril pad and tape was applied over the chambers to secure the occlusive patches to the skin. Two additional sites with no Butenafine HCl 1% (untreated sites) were also occluded. Sites were at least 2.5 cm apart. The patches were removed 24 hours later and the sites were lightly wiped. Test sites were evaluated. Butenafine HCl 1% (2 μl/cm\^2) was applied to the treated irradiated site. After 15 minutes, the treated irradiated site and the untreated irradiated site were irradiated with 0.5 MED of UVA/UVB irradiation followed by 10 Joules/cm\^2 of UVA from a xenon arc solar simulator equipped with a Schott WG345 to eliminate UVB radiation. The remaining sites served as the treated non-irradiated site and untreated non-irradiated site.
