Primary Outcome Measures:
  • Complete Cure of Interdigital Tinea Pedis [ Time Frame: Visit 4/ Week 6 ]

    The primary efficacy comparison between NAFT-600 gel and placebo will be based on the percentage of subjects at Week 6 with complete cure of interdigital tinea pedis.

    Complete cure is defined as negative mycology results (dermatophyte culture and KOH) and the absence of erythema, scaling, and pruritus.

Secondary Outcome Measures:
  • Effective Treatment and Mycological Cure of Interdigital Tinea Pedis at Week 6 [ Time Frame: Visit 4/ Week 6. ]

    Effective treatment of interdigital tinea pedis which is defined as negative KOH and negative dermatophyte culture and erythema, scaling, and pruritus scores of 0 or 1 (corresponding to absent and mild respectively).

    Mycological cure of interdigital tinea pedis which is defined as negative KOH and negative dermatophyte culture.
