Conditions: Hypersensitivity
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 32
Healthy volunteers: yes

Brief summary:
In this study researchers want to study the potential skin reaction after repeated application of an antifungal cream containing trolamine. The study plans to enroll about 32 healthy female or male participants with the age 18 - 79 years. Researchers will apply on the skin of the upper back between the shoulder blades of the study participants three different patches to cover a small amount of the antifungal cream or 0.3% solution of sodium lauryl sulfate, which is known to cause skin irritation (so called positive control). A third patch will cover a skin area without any product (so called negative control). Participants will return daily to the study center to have new patches containing the test products applied on the same skin area of the back, excluding weekends, for 21 days of continuous skin contact. At each visit the skin will be investigated by the researchers for redness, dryness and other reactions to learn about the skin reaction after repeated application.

Detailed description:

Arms:
arm 1: Participants received butenafine HCl 1% cream on the skin test site, 0.3% solution of sodium lauryl sulfate on the skin Positive Control test site, and a blank patch on the skin Negative Control test site daily (excluding weekends) for 21 days, or 15 applications.

Interventions: intervention 1: Butenafine HCl 1% (BAY1896425) intervention 2: Positive Control-Sodium lauryl sulfate (SLS) intervention 3: Negative Control
Intervention descriptions: intervention 1: Approximately 0.2 g of cream containing butenafine HCl 1% daily (excluding weekends) was applied to the absorbent pad portion of a semi-occlusive dressing, which was then applied to the skin test site. The total dose applied to each participant completing the trial was 3 g. intervention 2: Approximately 0.2 mL of 0.3% solution of sodium lauryl sulfate was applied to the absorbent pad portion of a semi-occlusive dressing, which was then applied to the Positive Control test site. intervention 3: A blank patch was applied to the Negative Control test site.
