About this study

Official title: Single Dose Bioequivalence and Adhesion Study of Rotigotina B7 TDS (2 mg/24h) (Rotigotine Transdermal Patch 2 mg/24 Hours) and 'NEUPRO®' (Rotigotine) 2 mg/24 Hours Transdermal Patch in Healthy Adult Human Participants.

This study was intended to demonstrate bioequivalence of the Amarin's Rotigotine patch respect to Neupro, (RLD), as well as non-inferiority in adhesion, when tested at a dose of 2 mg/24h in healthy subjects of both sexes. Local and systemic adverse events were also monitored and reported. Worn patches were recovered and analysed to compare residual drug.

Read the detailed description

Objectives:

  • To evaluate the bioequivalence and the non-inferiority in the adhesion of Rotigotina B7 TDS (2 mg/24h) (Rotigotine Transdermal Patch 2 mg/24 hours) respect to 'NEUPRO®' (Rotigotine) 2 mg/24 hours Transdermal Patch in healthy, adult human participants.
  • To compare the residual drug content, cold flow properties and to monitor the safety and tolerability of the participants.

Methodology:

This evaluator-blinded, randomized, two-period, two-treatment, four-sequence, crossover, balanced, single dose bioequivalence and adhesion study in healthy adult human participants was conducted to evaluate the bioequivalence and the non-inferiority in the adhesion of test formulation respect to reference formulation. The study was conducted with 36 (32 Male + 04 Female) participants and 35 participants (31 Male + 04 Female) completed the study in accordance with protocol. A single patch of either the test product Rotigotina B7 TDS (2mg/24h) (Rotigotine Transdermal Patch 2 mg/24 hours) (T) or the reference product (R). Neupro® 2 mg/24 h Transdermal Patch Rotigotin (e) was applied for 24 hours on the healthy skin (that was clean, dry, hairless and free of redness, irritation, burns or cuts) on left or right side of upper arm according to the randomization schedule of each participant in each study period (on Day 0 for Period 1 and Day 3 for Period 2) at ambient temperature.

Blood samples were collected at pre-dose (0.0 hour) and at 1.0, 2.0, 3.0, 4.0, 6.0, 8.0, 10.0, 12.0, 13.0, 14.0, 15.0, 16.0, 17.0, 18.0, 19.0, 20.0, 22.0, 24.0 (prior to removal), 26.0, 28.0, 32.0, 36.0, 42.0 and 48.0 hours post dose in each period. The plasma samples were shipped to the Bioanalytical facility for analysis.

Statistical analysis was performed on pharmacokinetic parameters to compare and evaluate the bioequivalence and statistical analysis was performed on adhesion score data to evaluate the non-inferiority in the adhesion of test formulation to the reference formulation. Bioequivalence was determined by a statistical comparison of Cmax, AUCt and AUCi for the test and reference products for Rotigotine. To demonstrate adhesiveness, the 90% confidence interval of mean adherence for the test product at the end of the dosing interval was to be lie above 90%.

    The area under the plasma concentration versus time curve (AUC 0-t) 90% confidence limits of T/R ratio must lie within 80-125 %

    Measured: 24 Hours

  4. Bioequivalence based on AUCi

    The area under the plasma concentration versus time curve extrapolated to infinite (AUC i) 90% confidence limits of T/R ratio must lie within 80-125 %

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Rotigotine Transdermal Delivery System (TDS) in people with Bioequivalence and Adhesion, run by Amarin Technologies S.A.U. at 1 site in India.

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 19 inclusion and 47 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 Aug 2026. 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 India. 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?

Bioequivalence based on Cmax (time frame: 24 Hours). 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?
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 Aug 2026.
