About this study
Official title: Clinical Evaluation of Bacitracin. A Phase II Dose-Response Study
The purpose of this study is to establish a concentration of a bacitracin-patch for diagnosing allergic contact dermatitis.
Read the detailed description
Thin-layer Rapid Use Epicutaneous Test (T.R.U.E. Test®) is a ready-to-use patch test method designed for diagnosis of allergic contact dermatitis.
The standard panel consists of two tape strips, panel 1, with 11 allergen patches and a negative control and panel 2, with 12 allergen patches. T.R.U.E. TestTM panels 1 and 2 contain 23 of the most frequent contact allergens. With the 23 allergens the test currently consists of, it is possible to detect about 60-70% of contact allergic reactions. Thus, there is a need for expanding the number of allergens included in T.R.U.E.Test in order to detect more contact allergic reactions. Bacitracin is one of these allergens, and the purpose of this study is to determine a concentration for the patch by using a bacitracin dilution series.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing bacitracin (allergen) in people with Allergic Contact Dermatitis, run by Mekos Laboratories AS at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Oct 2005. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Skin reaction to the patch test after 72-96 hours and after 7 days. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Oct 2005.
