About this study
Official title: A Phase I, Randomized, Observer-blind, Single-center, Vehicle- And Comparator-controlled, Initial Dose-ranging Study To Assess The Antipsoriatic Efficacy Of Different Concentrations Of An2728 Cream In A Psoriasis Plaque Test
The purpose of this study is to investigate dose-response relationship, antipsoriatic efficacy and safety of different concentrations of topical formulations with AN2728 in subjects with psoriasis vulgaris.
Read the detailed description
The study will be performed in 12 male subjects with stable psoriatic plaques. The study preparations and the comparator will be tested observer-blind. Treatments will be randomly assigned to the test fields. All subjects will receive all treatments, with intraindividual comparison of the treatments.
Altogether six test fields will be examined per subject (four active AN2728 creams of different concentrations: 2 %, 1 %, 0.3 %, 0.03 %, the active ingredient-free vehicle, and a marketed corticoid preparation). The test fields will be treated occlusively over a study period of 12 days. Topical application of approximately 200 uL of each assigned intervention is administered per treatment, for a total of 10 treatments over a 12-day treatment period.

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 4 inclusion and 13 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 27 Feb 2019. 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 Germany. 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. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Efficacy of the active study preparations compared to the corresponding vehicle using differences in infiltrate thickness on study day 12. (time frame: Day 12). 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 27 Feb 2019.
