Eligibility Criteria

18 Years - undefined (Adult, Older Adult)MaleAccepts Healthy Volunteers

Inclusion Criteria:

Subjects must meet all of the following criteria to be included in the study:

  1. Witnessed, signed informed consent approved by Institutional Review Board/Independent Ethics Committee.

  3. Male Subjects of any race 18 years of age and older.
  4. Subjects with a clinical diagnosis of interdigital T. pedis T. pedis interdigital defined as 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).
  5. Provisionally confirmed diagnosis at baseline by a positive potassium hydroxide (KOH) wet mount at the clinical site.
  6. The sum of the clinical signs and symptoms scores of the target lesion is at least 4 using the Grading and signs and symptoms of T. pedis detailed in section 6.6.1, including a minimum score of at least 2 for erythema AND a minimum score of 2 for either scaling/fissures or pruritus/burning (on a scale of 0-3, where 2 indicates moderate severity).

Outcomes

Primary Outcome Measures

Local Tolerability
Tolerability will be evaluated through assessment local signs and symptoms. Scoring for Fissuring/Cracking, Erythema, Maceration, Scaling, Pruritus, Burning/Stinging: 0 = none (complete absence) = mild (slight) = moderate (definitely present) = severe (marked, intense)

Secondary Outcome Measures

Efficacy 1: Presence and Persistence of J. lividum
Proportion of samples at each time point in which J. lividum can be detected.
Efficacy 2: Clinical Response
Changes in signs and symptoms of T. pedis Scoring Measure for Fissuring/Cracking, Erythema, Maceration, Scaling, Pruritus, Burning/Stinging: Scoring Measure: 0 = none (complete absence) = mild (slight) = moderate (definitely present) = severe (marked, intense)

5. Study Description

Brief Summary
This is an open- label, single- dose, dose escalating evaluation of the safety and tolerability of three dose levels of DBI-001 in patients with Tinea pedis. The purpose of the current protocol is to establish the safety and tolerability of a single application of J. lividum to the feet of patients with proven T. pedis. In addition, the effect of J liv on the T. pedis will also be evaluated.
Detailed Description
Open- label, single- dose, dose escalating evaluation of the safety and tolerability of three dose levels of DBI-001 in patients with Tinea pedis. Study Objectives and Purpose The purpose of the study is to evaluate the safety and tolerability of DBI-001 in patients with Tinea pedis. Secondly to evaluate presence or persistence of J. lividum of DBI-001 following a single application of DBI-001. Thirdly to see the effect on the abundance of T. rubrum. Lastly to see the effect of a single application of DBI-001 on the signs and symptoms of interdigital T. pedis. Tolerability will be evaluated through assessment of selected local signs and symptoms (pain / burning / stinging, pruritus, erythema, edema, and scabbing / crusting). Any local skin reaction that requires use of a concomitant therapy or study discontinuation will be reported

Phase 2
Interventional Study Model
Single Group Assignment
Model Description
A single center open label dose escalating study design will be used in a population of patients with interdigital Tinea pedis. Each subject will have a single application of the test article applied to each foot. The three test articles will be a low dose, medium and a high dose of J. lividum. Each of the three groups will have 4 subjects. After the first cohort has completed their day 7 visits and if no significant tolerability of safety issues is identified the second cohort will be enrolled. After the second cohort has completed the day 7 visits and if no significant tolerability or safety issues are identified the third cohort will be enrolled. At all evaluations, signs and symptoms of application site reactions will be recorded at baseline, as well as days 2, 3, 7, 14, and 28.
