Open Label, Single-dose, Dose Escalating Evaluation of the Safety and Tolerability of DBI-001 in Patients With T. Pedis

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.

2. A signed Health Information Portability and Accountability Act (HIPAA) authorization form which permits the use and disclosure of subject's individually identifiable health information.

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).
