The purpose of this study is to evaluate skin irritation and photo irritation of JNJ 10229570-AAA on intact skin of Japanese healthy male participants.
This is a single center, interpreter-blinded (the person interpreting the results does not know the name of the assigned drug), randomized (drug is assigned by chance like flipping a coin), vehicle-controlled, closed-patch test study. Thirty (30) Japanese participants will be enrolled in the study. Each treatment (JNJ 10229570-AAA at 1.2%, 2.4%, 3.6%, vehicle in a cream formulation, and petroleum jelly) will be randomly applied in vertical position on the back of each participant, with a corresponding strength applied at the same vertical position (left vs. right). The study drugs applied on the left side will be washed off at 48 hours after application. The dermatological evaluation and photo shoots will be done at 1 (T49) and 24 (T72) hours after washing off the drugs. All participants who completed the dermatological evaluation will be included in the evaluation of skin irritation and skin photo irritation. The study drugs applied on the right side will be washed off at 24 hours after application. The dermatological evaluation and photo shoots will be done at 1 hour after washing off. Ultraviolet A (UVA) will be irradiated to the application site. One hour after irradiation start (T26), the dermatological evaluation and photo shoots will be done. Afterwards the application site will be covered for the protection against UV. Twenty-four hours after washing off (T48), the cover will be taken off, and then the dermatological evaluation and photo shoots will be done at 1 (T49) and 24 (T72) hours. Additionally, the safety profile of JNJ 10229570-AAA will be assessed during the study. The study has a total duration of maximum 32 days.

Skin irritation according to the Japanese evaluation criteria (scores on a scale)
The Japanese skin irritation evaluation criteria is a 6-point scale specifying the irritation level of the skin, from 0 (no response) to 4 (blister)
Time frame: 72 hours
Skin photo irritation according to the Japanese evaluation criteria (scores on a scale)
The Japanese skin photo irritation evaluation criteria is a 6-point scale specifying the level of skin photo irritation from 0 (lack of reaction or reaction comparable to non-irradiated site) to 4 (reaction four ranks more pronouced using domestic criteria compared with non-irradiated site)
Time frame: 72 hours
Skin irritation according to the International Contact Dermatitis Research Group (ICDRG) criteria (measurements on a scale)
The ICDRG scale measures the level of skin irritation from Negative (no reaction) to Extreme Positive Reaction (erythema, infiltration, confluent vesicles)
Time frame: 72 hours
Skin photo irritation according to the International Contact Dermatitis Research Group (ICDRG) criteria (measurements on a scale)
The ICDRG scale measures the level of skin irritation from Negative (no reaction) to Extreme Positive Reaction (erythema, infiltration, confluent vesicles)
Time frame: 72 hours
Number of participants with adverse events as a measure of safety and tolerability
Time frame: 32 days
