A Study to Evaluate the Potential of Tazarotene Foam to Cause a Reaction When Applied to the Skin and Exposed to Light on Healthy Volunteers

Summary

The purpose of this study is to evaluate the potential of Tazarotene Foam to induce a phototoxic reaction when exposed to UV and VIS light on skin of healthy volunteers.

Conditions

• Acne Vulgaris

Interventions

DRUG

Tazarotene Foam without irradiation

Each subject will be exposed to a patch with tazarotene foam during a single, 24 hour application period. This patch will then be removed and those sites will serve as nonirradiated control. Patch sites will be evaluated for signs of inflammatory skin responses (eg, erythema and local skin reactions) and superficial effects 1 ±0.25 hour after patch removal, and during follow-up visits at 24 ±1 hours, 48 ±2 hours, and 72 ±2 hours after patch removal.

DRUG

Tazarotene Foam with UVA and UVB irradiation

Each subject will be exposed to a patch with tazarotene foam during a single, 24 hour application period. The patch will be removed and that site will be exposed to ultraviolet A (UVA) and to UVA/ultraviolet B (UVB) radiation wavelengths (UV only). Patch sites will be evaluated for signs of inflammatory skin responses (eg, erythema and local skin reactions) and superficial effects 1 ±0.25 hour after patch removal, and during follow-up visits at 24 ±1 hours, 48 ±2 hours, and 72 ±2 hours after patch removal.

DRUG

Tazarotene Foam with UVA, UVB, and visible light

Each subject will be exposed to a patch with tazarotene foam during a single, 24 hour application period. The patch will be removed and that site will be exposed to UVA, UVA/UVB, and visible light (VIS) wavelengths (UV plus VIS). Patch sites will be evaluated for signs of inflammatory skin responses (eg, erythema and local skin reactions) and superficial effects 1 ±0.25 hour after patch removal, and during follow-up visits at 24 ±1 hours, 48 ±2 hours, and 72 ±2 hours after patch removal.

DRUG

Vehicle Foam without irradiation

Each subject will be exposed to a patch with vehicle foam during a single, 24 hour application period. This patch will then be removed and those sites will serve as nonirradiated control. Patch sites will be evaluated for signs of inflammatory skin responses (eg, erythema and local skin reactions) and superficial effects 1 ±0.25 hour after patch removal, and during follow-up visits at 24 ±1 hours, 48 ±2 hours, and 72 ±2 hours after patch removal.

DRUG

No Treatment without irradiation

Each subject will be exposed to a blank patch during a single, 24 hour application period. This patch will then be removed and those sites will serve as nonirradiated control. Patch sites will be evaluated for signs of inflammatory skin responses (eg, erythema and local skin reactions) and superficial effects 1 ±0.25 hour after patch removal, and during follow-up visits at 24 ±1 hours, 48 ±2 hours, and 72 ±2 hours after patch removal.
