Study summary

Placebo Controlled Trial of the Safety and Efficacy of DBI-001 in Patients with Interdigital Tinea pedis (T. pedis)

Read the detailed description

Double-Blind, Randomized, Placebo Controlled Trial of the Safety and Efficacy of DBI-001 Gel in Patients with Interdigital Tinea pedis (T. pedis). The primary objective is to observe the antimicrobial effect of a daily application of DBI-001Gel for 4 weeks in patients with interdigital T. pedis based on the change from culture positive for a dermatophyte to culture negative as determined by routine mycology culture.

Inclusion criteria

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

    1. A signed approved form 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.
    3. Male or Female Subjects of any race 18 years of age and older.
    4. Women patients of must: a. Have negative urine pregnancy tests prior to study treatment to rule out pregnancy, and b. Use at least one method of that results in a low failure rate (i.e. less than 1% per year) when used consistently and correctly such as implants, injectables, combined oral contraceptives, some intrauterine devices (IUDs), sexual abstinence or vasectomized partner for the duration of study participation.
    5. 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).
    6. Provisionally confirmed diagnosis at screening by a positive potassium hydroxide (KOH) wet mount at the clinical site.
    7. A positive dermatophyte culture from the sample obtained at the screening visit.
    8. The sum of the clinical signs and symptoms scores of at least one web space (Target web space) is at least 4 using the Grading of Signs and Symptoms of T. pedis 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).
    9. Target web space should have adequate amount of leading-edge scale to provide enough scale for KOH, fungal culture and molecular diagnostics.

Exclusion criteria

Exclusion Criteria:

Subjects with the following will be excluded from this study:

<!-- -->

  1. Females who are pregnant, planning a pregnancy, breastfeeding or have a positive pregnancy test at the site.
  2. Any dermatological conditions that could interfere with clinical evaluations.
  3. The clinical diagnosis of moccasin T. pedis.
  4. Any underlying disease(s) or some other dermatological condition that requires the use of interfering topical or systemic therapy.
  5. Subjects that have not undergone the specified (s) or subjects who require the concurrent use of specific topical medications applied to the foot.
  6. Subjects that have not undergone the washout periods for systemic medications or who require the use of specific systemic medications.
  7. Treatment of any type of cancer within the last 6 months.
  8. History of any significant internal disease (which contraindicates use of live microbiome e.g. leukemia, liver failure, cardiovascular disease).
  9. Subjects who are known to be allergic to any of the Test Article(s) or any components in the Test Article(s) or history of or allergic reactions to any of the study preparations as described in the Investigator's Brochure.
  10. AIDS or AIDS related complex by medical history.
  11. Known or suspected immune suppressive medications or diseases.
  12. Diabetes mellitus Type I or II by medical history.
  13. Peripheral vascular disease based on medical history.
  14. Any subject not able to meet the study attendance requirements.
  15. Subjects who have participated in any other trial of an drug or device within 30 days prior to enrollment or participation in a research study concurrent with this study.
Terms in these criteria, in plain language(6)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Washout period

A planned gap after a treatment, so that its effects can lessen before the study treatment or a study assessment. Ask the study team and the doctor who prescribed it before changing any medicine.

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. From Culture Positive to Culture Negative

    Antimicrobial effect. Effect will be measured by change from culture positive for dermatophyte to culture negative as determined by routine mycology culture.
