Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
876

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

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:

  • 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 is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Proportion of Patients in Each Active Treatment Group Who Are Considered a Therapeutic Cure
Time Frame: Day 42
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
Day 42
Proportion of Patients in Each Treatment Group Who Are Considered a Therapeutic Cure
Time Frame: Day 42
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
Day 42

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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)
Time Frame: Day 42
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
Day 42
Proportion of Patients in Each Active Treatment Group Who Are Considered a Mycological Cure
Time Frame: Day 42
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
Day 42
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)
