Inclusion criteria

  • Healthy male or non-pregnant, non-lactating female ≥ 18 years of age.
  • Clinical diagnosis of tinea pedis with lesions localized to the interdigital spaces or predominantly interdigital, but may extend to other areas of the foot (the non-interdigital lesions should not be hyperkeratotic, i.e., characteristic of tinea pedis moccasin).
  • Provisionally confirmed at baseline by a positive potassium hydroxide (KOH) wet mount preparation
  • Total score ≥ 4 for the clinical signs and symptoms of tinea pedis in the target area. In addition the target area must have a minimum score of at least 2 for erythema and a minimum score of at least 2 for either pruritus or scaling.

Exclusion criteria

Exclusion Criteria:

  • Presence of any other infection of the foot or other disease process that, in the Investigator's opinion, may interfere with the evaluation of the patient's tinea pedis
  • History of or current psoriasis, Lichen planus or contact dermatitis involving the feet within the previous 12 months.
  • Past history of dermatophyte infections with a lack of response to antifungal therapy
  • Confluent, diffuse moccasin-type tinea pedis of the entire plantar surface or onychomycosis involving ≥ 20% of the area of either great toenail and/or involving more than five toenails in total or other concurrent dermatophytoses (e.g., tinea cruris) and any other skin disease to an extent that, in the opinion of the investigator, might interfere with the evaluation of tinea pedis or study results

What researchers measure

Primary outcomes

  1. Proportion of Patients in Each Active Treatment Group Who Are Considered a Therapeutic Cure

    To be considered a Therapeutic Cure, the patient must have both Clinical Cure (patient's total severity score must be ≤ 2 with no individual severity score \> 1) and Mycological Cure (patient must have a negative KOH test and a negative fungal culture) of tinea pedis

    Time frame: Day 42

  2. Proportion of Patients in Each Treatment Group Who Are Considered a Therapeutic Cure

    To be considered a Therapeutic Cure, the patient must have both Clinical Cure (patient's total severity score must be ≤ 2 with no individual severity score \> 1) and Mycological Cure (patient must have a negative KOH test and a negative fungal culture) of tinea pedis

    Time frame: Day 42

Secondary outcomes

  1. Proportion of Patients in Each Active Treatment Group Who Are Considered a Clinical Cure (Patient's Total Severity Score Must be ≤ 2 With no Individual Severity Score > 1)

    The following Clinical Signs and Symptoms of a target lesion with tinea pedis are individually rated for severity (none, mild, moderate, or severe): fissuring/cracking, erythema, maceration, scaling, pruritus, and burning/stinging

    Time frame: Day 42

  2. Proportion of Patients in Each Active Treatment Group Who Are Considered a Mycological Cure

    To be considered a mycological cure the patient must have a negative KOH test and a negative fungal culture for T. rubrum, T. mentagrophytes or E. floccosum

    Time frame: Day 42

  3. Proportion of Patients in Each Treatment Group Who Are Considered a Clinical Cure (Patient's Total Severity Score Must be ≤ 2 With no Individual Severity Score > 1)

    The following Clinical Signs and Symptoms of a target lesion with tinea pedis are individually rated for severity (none, mild, moderate, or severe): fissuring/cracking, erythema, maceration, scaling, pruritus, and burning/stinging

    Time frame: Day 42

  4. Proportion of Patients in Each Treatment Group Who Are Considered a Mycological Cure

    To be considered a mycological cure the patient must have a negative KOH test and a negative fungal culture for T. rubrum, T. mentagrophytes or E. floccosum
