Skin Irritation Potential of MOB015B in Healthy Subjects Using a Cumulative Irritant Patch Test Design

A 21-Day, Randomized, Controlled Study to Evaluate the Skin Irritation Potential of MOB015B in Healthy Subjects Using a Cumulative Irritant Patch Test Design To evaluate the irritation potential of MOB015B on normal skin. Single center, randomized, controlled, evaluator blinded, within-subject comparison study

MOB015B is a newly developed topical solution for the treatment of nail fungus (onychomycosis) containing the active antifungal ingredient terbinafine. A This study investigates the irritation potential of MOB015B under standardized conditions compared with a known irritant (0.2% SLS) and an inert control (normal saline). Because MOB015B is formulated for topical use, it is necessary to determine the potential of this product to cause irritation after repeated topical application to the skin.

Abstinence or vasectomies are acceptable if the female subject agrees to implement one of the other acceptable methods of birth control if her lifestyle/partner changes;

5. Is free of any systemic or dermatological disorder, which, in the opinion of the Investigator, will interfere with the study results or increase the risk of AEs;
6. Is of any Fitzpatrick Skin Type or race, providing the skin pigmentation will allow discernment of erythema
