Comparing Skin Adhesiveness of a New Rotigotine 12 mg/24 h Transdermal Patch Versus Standard Treatment in Patients with Parkinson’s Disease

2 1 1 1

What is this study about?

This clinical trial is investigating the skin adhesion properties of a newly developed Rotigotine 12 mg/24 h transdermal patch compared to a reference product in patients with Parkinson’s disease. Parkinson’s disease is a progressive neurological disorder that affects movement, causing tremors, stiffness, and difficulty with balance and coordination. Rotigotine is a medication used to treat symptoms of Parkinson’s disease by delivering the medication through a patch that sticks to the skin and releases the drug continuously over 24 hours.

The purpose of this study is to compare how well the new Rotigotine patch adheres to the skin compared to the currently available patch. This is important because proper adhesion ensures consistent delivery of medication. The study has a crossover design, meaning that participants will try both the test patch and the reference patch at different times during the study, allowing for direct comparison between the two products.

During the trial, participants will wear each type of patch, and researchers will assess how well the patches remain attached to the skin near the end of the wearing period (after almost 24 hours). The study will also monitor any adverse events (unwanted side effects) that might occur during the use of either patch. Participants will need to avoid activities like swimming, bathing, or using saunas on assessment days as these could affect how well the patches stick to the skin.

1 Initial Patch Application

After joining the trial, you will be assigned to start with either the new rotigotine patch (Test product) or the standard Neupro 8 mg/24 h transdermal patch (Reference product).

The patch will be applied to your skin. Both patches contain rotigotine, a medication used to treat Parkinson’s disease symptoms.

You must already be using a stable dose of at least 12 mg/24 h of rotigotine for at least 2 weeks before starting the trial.

2 Wearing the First Patch

You will wear the first assigned patch for approximately 24 hours.

During this time, you should avoid swimming, bathing, or using a sauna, especially on assessment days.

The patch should remain attached to your skin throughout the entire 24-hour period.

3 First Assessment Period

After nearly 24 hours (specifically at 23 hours and 55 minutes), a healthcare professional will examine how well the patch has adhered to your skin.

They will assess and record the adhesion properties of the patch, checking if it has remained properly attached or if there has been any lifting or detachment.

4 Crossover to Second Patch

After completing the assessment of the first patch, you will switch to the other patch type (if you started with the Test product, you’ll now use the Reference product, or vice versa).

This is known as a crossover design, allowing you to try both patch types during the trial.

5 Wearing the Second Patch

You will wear the second patch for approximately 24 hours, following the same instructions as with the first patch.

The same restrictions apply regarding swimming, bathing, and sauna use.

6 Second Assessment Period

After nearly 24 hours with the second patch, another assessment will be conducted to evaluate its adhesion properties.

The healthcare team will compare how well both patches adhered to your skin during the 24-hour periods.

7 Monitoring for Side Effects

Throughout the trial, the healthcare team will monitor and record any adverse events (AEs) you experience. These are any unfavorable or unintended signs, symptoms, or diseases that occur during the trial.

They will also specifically track adverse events of special interest (AESIs), which are particular side effects they are especially concerned about monitoring.

8 Trial Completion

The trial is expected to run until October 15, 2025, with final results available by December 15, 2025.

After completing both patch assessments and any follow-up evaluations, your participation in the trial will be complete.

Investigated drugs:

Rotigotine

Rotigotine is a medication delivered through a transdermal patch (a patch that sticks to your skin) used to treat Parkinson’s disease. It works by mimicking the effects of dopamine, a natural substance in the brain that helps control movement and is lacking in people with Parkinson’s disease. The patch releases the medication continuously through the skin into the bloodstream over 24 hours.

Investigated diseases:

Parkinson's disease

Parkinson’s disease – A progressive neurological disorder that affects movement, characterized by tremors, muscle rigidity, bradykinesia (slowness of movement), and impaired balance and coordination. The disease occurs when nerve cells in the brain that produce dopamine become impaired or die, leading to a decrease in dopamine levels. As the disease progresses, patients may experience difficulty with walking, talking, and completing simple tasks. Non-motor symptoms can include depression, cognitive changes, sleep problems, and sensory abnormalities. Parkinson’s disease typically develops gradually, with symptoms worsening over time as more dopamine-producing cells are lost.
