Skin Safety Study to Evaluate the Sensitizing Potential in Healthy Volunteers

A Phase 1, Randomized, Evaluator Blinded, Controlled Study to Evaluate the Sensitizing Potential of M518101 in Healthy Volunteers Using a Repeat Insult Patch Test Design

This is a single center, randomized, controlled, within subject comparison, multiple dose study to determine the sensitization potential of M518101 on normal skin under occlusive patch condition.

During the Induction Phase of the study, the study drugs and controls will be applied 9 times for 21 days on the infrascapular area of the back under occlusive patch conditions.

Following induction, subjects will have a 10 to 14-day Rest phase, after which they will enter the challenge Phase, which consists of one 48-hour patch application (occlusive) to a naïve site on the opposite side of the back.

• Subjects must be able to communicate with the investigator and understand and comply with the requirement of the study and visit schedule

Exclusion Criteria:

• Have any visible skin disease at the application site which will interfere with the evaluation of the test site reaction
• Have damaged skin in or around the test sites
• Have a history of sensitivity to adhesive tape
