Study summary

This is a three-arm randomized controlled trial to assess the efficacy of an experimental treatment in the treatment of tinea pedis (athlete's foot). The experimental treatment will be tested against a vehicle control to determine efficacy and safety, and against an active comparator to evaluate the success of the treatment relative to an existing gold-standard treatment. Patients will be treated for four weeks, with their condition being assessed at the end of treatment and two weeks after the end of treatment. The primary endpoint for this study is effective treatment rate at the week 6 evaluation, defined as a mycological cure and minimal clinical signs \& symptoms. Secondary endpoints include safety and patient evaluation of treatment.

What researchers measure

Primary outcomes

  1. Effective Treatment (Mycological Cure and Minimal Symptoms)

    Binary outcome measure defined as mycological cure AND a total clinical assessment score less than or equal to 2 (out of a possible 18). Mycological cure is defined as negative potassium hydroxide microscopy, while the clinical assessment is based on a sum of 6 symptoms (desquamation, vesiculation, erythema, fissuring, maceration, and pruritus) scored 0-3 by a physician.

    Time frame: 6 weeks

Secondary outcomes

  1. Rate of Adverse Events

    To examine treatment safety, we will calculate the rate of adverse events and serious adverse and compare them between the study's three arms using Chi-square tests to evaluate whether a statistically significant difference is present.

    Time frame: 6 weeks

  2. Effective Treatment (Mycological Cure and Minimal Symptoms)

    Effective treatment as defined above, but measured at the end of treatment (4 weeks after the beginning of participation).

    Time frame: 4 weeks

  3. Patient Satisfaction Score

    At the conclusion of treatment, patients complete a brief survey on their impressions of the treatment's tolerability, effectiveness, and convenience on a five-point scale, where 1 = poor, 2 = fair, 3 = good, 4 = very good, 5 = excellent, or they may answer with "No answer/prefer not to say". Scores will be compared for each of the three characteristics and as a sum of the three scores.

    Time frame: 4 weeks

  4. Self-Reported Patient Compliance

    On the same experience questionnaire, patients are asked to estimate how many doses of treatment they missed or forgot to take. Possible answers are None, 1-2, 3-4, 5-6, 7-8, or 9 or more. This indicates whether there is a significant difference in patients' likelihood to adhere to a treatment regimen.

    Time frame: 4 weeks
