Outcome Measures

Primary Outcomes (2)

  • Therapeutic Cure - Superiority Analysis

    Therapeutic Cure requires both Clinical Cure and Mycological Cure. Clinical Cure was based on the following signs and symptoms: fissuring, erythema, maceration, vesiculation, scaling, exudation, pruritus, burning. Each clinical symptom was evaluated using a 0-3 point rating scale: none=0, mild=1, moderate=2 or severe=3. If the score for erythema was ≤ 2 and the sum for all of the other 7 signs and symptoms was \<2 then the patient was considered a Clinical Cure. Mycological Cure: The potassium hydroxide (KOH) and the fungal culture were both negative.

    42 days

  • Therapeutic Cure Non-Inferiority Comparison of Butenafine Cream and Lotrimin Ultra

    Patient was cured both by symptoms (Clinical Cure) and by the results of fungal testing (Mycological Cure).

Eligibility Criteria

Age12 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Microbiologically confirmed clinical diagnosis of interdigital tinea pedis
  • If female and of child bearing potential, prepare to abstain from sexual intercourse or use a reliable method of contraception during the study (e.g., condom, intra-uterine device (IUD), oral, transdermal, injected or implanted hormonal contraceptives).
  • A confirmed clinical diagnosis of interdigital tinea pedis. Lesions are to be predominately interdigital but may extend to other areas of the foot (the non-interdigital lesions must not be hyperkeratotic).
  • The presence of tinea pedis infection, confirmed by the observation of segmented fungal hyphae during a microscopic potassium hydroxide (KOH) wet mount examination (potassium hydroxide mount preparation).
  • Identification of an appropriate dermatophyte by culture sent to the central laboratory. The appropriate dermatophytes are Trichophyton rubrum, Trichophyton mentagrophyte or Epidermophyton floccosum.

You may not qualify if:

  • Use of any of the following within the indicated timeline:
  • Oral or injectable steroids
  • Any oral anti-fungals within 4 weeks of the study start
  • Use of topical corticosteroids or any other topical antipruritics on the feet within 72 hours of the study start.
  • Any prescription or over-the-counter (OTC) topical antifungals on the feet within two weeks prior to study entry
  • Use of any antihistamines within 72 hours of the study start.
  • Any known hypersensitivity to butenafine or other antifungal agents.
  • Evidence of any concurrent dermatophytic infection of toe nails (onychomycosis) or other dermatological condition of the foot that may interfere with the Investigator's evaluation of tinea pedis.
  • Patients with recurrent tinea pedis (more than 3 infections in the past 12 months) who have been unresponsive to previous antifungal therapy.
