This is a multicenter, randomized, double-blind, placebo-controlled Phase 1b study in adult participants with tinea pedis caused by dermatophytes. The study will evaluate the safety, local tolerability, and pharmacokinetic profile of two concentrations of ZYG24004 (1% and 3%) after topical administration once or twice (once weekly for two consecutive weeks), and will explore preliminary efficacy.
