About this study

Official title: Open, Randomized, 2-period, 2-sequence, Cross-over Relative Bioavailability Study to Investigate the Pharmacokinetics and to Assess the Bioequivalence of a Rivastigmine Test Patch Formulation 9.5 mg/24 h (Twice-weekly Patch) (Luye Pharma AG, Germany) Compared to the Reference Patch Exelon® 9.5 mg/24 h (Once-daily Patch) (LTS Lohmann Therapie-Systeme AG, Germany) Applied for 11 Days

The present clinical trial will be conducted in order to compare the bioavailability of rivastigmine and to assess bioequivalence at steady-state of the marketed Test product Rivastigmine twice-weekly 9,5 mg/24 h transdermal patch (Manufacturer: Luye Pharma AG, Germany) and the marketed Reference product Exelon® 9.5 mg/24 h transdermal patch (Manufacturer: LTS Lohmann Therapie-Systeme AG, Germany) after multiple patch applications. Each of both treatments will last for 11 days with a washout period of at least 14 treatment-free days between the treatments.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. AUC96-264

    Partial area under the plasma concentration vs. time profile for the time interval 96 h 264 h

    Measured: From 96 to 264 hours after the first IMP application

  2. Cmax,96-264

    Maximum concentration in plasma during the nominal time interval 96 h-264 h, obtained directly from measured values

    Measured: From 96 to 264 hours after the first IMP application

  3. CTau264

    (Absolute) minimum concentration within the nominal time interval 96 h-264 h, obtained directly from measured values

    Measured: From 96 to 264 hours after the first IMP application

  4. Patch adhesion properties

    Lower one-sided 90% confidence limit for the mean of Test

    Measured: At 96, 168 and 264 hours after the first Test patch application

Secondary outcomes (1)

  1. Adverse events

    Descriptive evaluation of action taken, frequency, seriousness, intensity, relationship to the IMP/NIMP, and outcome, as well as period and treatment

    Measured: From 1st IMP application until individual discharge of a subject from the clinical trial, assessed up to approximately 2 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Rivastigmine twice-weekly 9,5 mg/24 h and Exelon® 9.5 mg/24 h in people with Bioequivalence, run by SocraTec R&D 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 7 inclusion and 33 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 2 Feb 2024. 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 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?

AUC96-264 (time frame: From 96 to 264 hours after the first IMP application). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05883124.

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 2 Feb 2024.
