About this study
Official title: Multiple Dose Bioequivalence Trial Comparing a Down-Scaled New Analgesic Transdermal Patch Formulation to an Analgesic Reference Patch (Protocol ID: 855509)
The purpose of this study is to determine whether two different analgesic transdermal patch formulations lead to same plasma levels of active ingredient after multiple dose application.
Read the detailed description
Main: To demonstrate the bioequivalence of the new transdermal patch versus the current transdermal patch (Reference) after multiple patch application. Pharmacokinetic target parameters are AUCss, and Css,max.
Further: To assess the safety, tolerability, skin tolerability and adhesiveness of the patch applications. To evaluate the following further Pharmacokinetic parameters: Css,min, Css,ave, PTF, Swing, tss,max, and t1/2,z

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Buprenorphine in people with Healthy, run by Grünenthal GmbH at 1 site in Germany.
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 25 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: stopped early, as of the sponsor's last update on 16 Nov 2007. 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. 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 was stopped early (reason given: The trail end was achived according to the definition in the trial protocol). Results are not available in the source record.
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.
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 16 Nov 2007.
