Inclusion Criteria:

- • Positive clinical findings for distal subungual onychomycosis as determined by clinical examination

  • Must have a great toenail involvement with onychomycosis in ≥25-≤65% of the visible nail. (more than one nail maybe affected however only the index great toenail will be evaluated)

  • Must agree to take measures to avoid pregnancy during the study period
  • Must agree to avoid the use of oral or topical antifungals unless provided by the investigator for the relief of symptomatic (active clinical signs) tinea pedis which has occurred during the treatment / follow up phase of the study. (The treatment provided will be Lotrimin®).

Exclusion Criteria:

- • The presence of proximal subungual onychomycosis or white superficial onychomycosis

  • Fungal involvement of the lunula or less than 2 mm of clear nail from the the proximal nail fold
  • Subjects with psoriasis, eczema, symptomatic (with active clinical signs) interdigital or plantar tinea pedis, lichen planus, or other abnormalities (e.g. traumatized or dystrophic nails) that could result in a clinically abnormal nail or the investigator thinks the current condition will compromise the integrity of the trial
