About

The investigational medicinal product (IMP) to be tested in the clinical trial (Rotigotine (ROT)-Transdermal System (TDS) (8 mg/24 h)), which is subject to this submission, was designed as a generic of Neupro® 8 mg/24 h, which is marketed in the European Union since 2006 (date of first authorisation is 2006, date of renewal of the authorisation is 2016) and serves as Reference product.

It is the intention of this clinical trial to assess patch adhesion properties of the newly developed rotigotine patch and the marketed Reference product Neupro® 8 mg/24 h after multiple patch applications.

Full description

This multi-centre, open, randomized (order of treatments), multiple dose trial will be performed in a 4-period, 2-sequence-crossover design. A washout phase is not needed, i.e. the IMP application of the 2nd study period may take place the day of the IMP removal of the 1st study period (direct switch-over) and so forth.

Patients with a diagnosis of idiopathic Parkinson's disease and a continuous and stable dose of rotigotine (at least 8 mg/24 h) including use of an 8 mg/24 hours patch will be randomized.

In each of the 4 periods 1 patch, either of Test or Reference will be applied, with a release rate of 8 mg/24 h rotigotine each. Each patch will remain applied for 24 h.

Assessment of patch adhesion will be performed 5 min after application of each patch as well as at the end of the application interval prior to removal of the patch.

The clinical trial will be performed as a crossover investigation with intra-individual comparison, thus reducing variability of the patch adhesion parameters, which is supposed to be higher between patients than within an individual patient.

The patients will continue their usual medications and will only replace one 8 mg/24 h rotigotine containing patch per day with the IMPs for the duration of treatment in the clinical trial. In case of prescribed doses above 8 mg/24 h rotigotine, the remaining dose will be provided by Non-Investigational Medicinal Pproducts (NIMPs). Thus, no interruption in the prescribed dose of rotigotine will occur.
