Inclusion criteria

  1. Healthy males and females aged more than or equal to 18 years
  2. 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), and provisionally confirmed at baseline by a positive potassium hydroxide (KOH) wet mount preparation (i.e., skin scrapings from the target site are placed on a microscope slide with a drop of 10% KOH, and microscopic examination reveals segmented fungal hyphae)
  3. The sum of the clinical signs and symptoms scores of the target lesion is at least 4, including a minimum score of at least 2 for erythema AND a minimum score of 2 for either scaling or pruritus (on a scale of 0-3, where 2 indicates moderate severity)

Exclusion criteria

Exclusion Criteria:

  1. Pregnant or lactating or planning to become pregnant during the study period
  2. Use of antipruritics, including antihistamines, within 72 hours prior to entry into the study
  3. Use of topical , antibiotics or antifungal therapy within 2 weeks prior to entry into the study
  4. Use of systemic (e.g., oral or injectable) corticosteroid, antibiotics or antifungal therapy within 1 month prior to entry into the study
  5. Use of oral terbinafine or itraconazole within 2 months prior to entry into the study
  6. Use of medication or radiation therapy within 3 months prior to entry into the study.
  7. Confluent, diffuse moccasin-type tinea pedis of the entire plantar surface.
  8. Presence of any other infection of the foot or other disease process that might confound the treatment evaluation
  9. History of dermatophyte infections unresponsive to systemic or topical antifungal drugs
  10. Known to Naftifine Hydrochloride or to any component of the formulation
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Study arms

  • Experimental
    Naftifine hydrochloride 2%

    A thin layer of sufficient quantity of Naftifine hydrochloride cream need to be applied to the affected areas plus an approximate ½ inch margin of healthy surrounding skin once daily consecutively for 2 weeks.

    Drug: Naftifine hydrochloride 2%

  • Active comparator
    Naftin® 2% (Naftifine hydrochloride 2%)

    A thin layer of sufficient quantity of Naftifine hydrochloride cream need to be applied to the affected areas plus an approximate ½ inch margin of healthy surrounding skin once daily consecutively for 2 weeks.

    Drug: Naftin® 2% (Naftifine hydrochloride 2%)

  • Placebo comparator
    Placebo vehicle cream.

    A thin layer of sufficient quantity of vehicle cream need to be applied to the affected areas plus an approximate ½ inch margin of healthy surrounding skin once daily consecutively for 2 weeks.

    Drug: Placebo

What researchers measure

Primary outcomes

  1. Mycological cure and clinical cure for a single target lesion for Trichyphyton rubrum

    After 6 weeks the skin scrapping will be collected for culture to find out the growth of T rubrum. Absence of growth suggests complete cure.

    Time frame: week 6 + 4 days

Secondary outcomes

  1. Mycological cure and clinical cure for Trichophyton rubrum, Trichophyton mentagrophytes, or Epidermophyton floccosum

    After 6 weeks the skin scrapping will be collected for culture to find out the growth of T rubrum, T Mentagrophytes or E floccosum. Absence of growth suggests complete cure.

    Time frame: week 6 + 4 days

Other outcomes

  1. Assessment of AEs for each treatment groups

    number of adverse events reported will be collated from all the treatment arms, to evaluate the safety of the study drugs.

    Time frame: week 6 + 4 days

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 11, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
