A Phase 2 interventional study of Janthinobacterium lividum in Tinea Pedis, sponsored by DermBiont, Inc.. Completed at 1 site in Dominican Republic. Open to male participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-06-17.

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. lividum on the T. pedis will also be evaluated.
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 test product will be applied by study personnel at the investigational site. Each subject will have a single application of approximately 0.5 ml of the test article applied to each foot. Both affected and unaffected feet will be treated covering the web spaces, toes, toe nails as well as the plantar and lateral aspect of both feet. Each of the three groups will have 4 subjects. After the first cohort has completed their day 7 visits, if no significant tolerability or safety issues identified the second cohort will be enrolled. After the second cohort has completed the day 7 visits and if no significant tolerability of safety issues is identified the third cohort will be enrolled.
73 studies on the registry are indexed under Tinea Pedis; 8 are open to participants now.
This study's enrollment of 12 is below the median of 128 across 66 interventional studies indexed under Tinea Pedis.

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.
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.
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.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
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.
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.

Safety Evaluation Cohort 1
Tolerability will be evaluated through assessment of local signs and symptoms. For simplicity, as there were no local tolerability reactions, the cumulative tolerability, inclusive of Pruritus, Erythema, Edema, Scabbing/crusting, and Burning/Stinging is represented in the table. Scoring for of each Pruritus, Erythema, Edema, Scabbing/crusting, and Burning/Stinging according to the scoring system below. Tolerability events were only considered adverse events if they were grade 3 or higher or required discontinuation of test article or use of conmeds. As no Tolerability events satisfied this criteria, there were no tolerability associated adverse events. 0 = none (complete absence) 1. = mild (slight) 2. = moderate (definitely present) 3. = Severe
Time frame: 28 days
