Brief Summary

This is a single center, randomized, controlled, within subject comparison, single dose study to determine the sensitization potential of SM04755 solution on normal skin under semi-occlusive patch conditions.

Detailed Description

This Phase 1, Repeat Insult Patch Test (RIPT) study is a single-center study of topical SM04755 solution repetitively applied to skin of healthy volunteers. This study will assess the potential of the Test Materials to induce contact sensitization as measured by treatment emergent adverse events (TEAEs), Reaction Grade and Investigator assessment of irritation and sensitization.
