A Phase 3b, Open-Label, Safety and Efficacy Study of Rotigotine as Add-On Therapy With Low Doses of Pramipexole or Ropinirole in Patients With Advanced Parkinson's Disease

An Open-Label Study to Investigate the Safety and Efficacy of Rotigotine Add-On Therapy With Low Doses of Pramipexole or Ropinirole in Patients With Advanced Parkinson's Disease Phase 3B

This study is to investigate the safety and efficacy of Rotigotine add-on therapy with low doses of Pramipexole or Ropinirole in patients with advanced-stage Parkinson's Disease (PD) who have insufficient response to L-dopa and low doses dopamine receptor agonists.

Inclusion Criteria:

• Subject is male or female, aged ≥ 30 and < 80 years at informed consent
• Subject has idiopathic Parkinson's Disease, of more than 3 years duration, as defined by the cardinal sign, bradykinesia, and the presence of at least 1 of the following: resting tremor, rigidity, impairment of postural reflexes, and without any known or suspected cause of Parkinsonism
• Subject has motor fluctuations such as wearing, dyskinesia
• Subject has experienced nocturias for at least 3 nights within 7 days prior to Baseline
• Subject is taking levodopa (L-DOPA, immediate and/or controlled release) in combination with benserazide or carbidopa and has been on a stable dose of L-DOPA for at least 28 days prior to Baseline (Visit 2)
• Subject is taking a non-ergot dopamine agonist (pramipexole ≤ 1.5 mg/day or ropinirole ≤ 6.0 mg/day) and has been on a stable dose of non-ergot dopamine agonist for at least 28 days prior to Baseline (Visit 2)

Exclusion Criteria:

• Subject is receiving therapy with tolcapone or budipine
• Subject is receiving therapy with one of the following drugs either concurrently or within 28 days prior to Baseline (Visit 2): alpha-methyl dopa, metoclopramide, reserpine, neuroleptics (except specific atypical neuroleptics: olanzapine, ziprasidone, aripiprazole, clozapine, quetiapine), monoamine oxidase A (MAO-A) inhibitors, methylphenidate, or amphetamine
• Subject has a history of symptomatic (not asymptomatic) orthostatic hypotension within the 6 months prior to Baseline (Visit 2)
• Subject has a known hypersensitivity to any components of the study medication, such as a history of significant skin hypersensitivity to adhesives, known hypersensitivity to other transdermal medications, or has unresolved contact dermatitis
• Subject is pregnant or nursing, or is of child-bearing potential (ie, is (i) not surgically sterile, or, (ii) not using adequate birth control methods [including at least one barrier method] or, (iii) not sexually abstinent, or (iv) not at least 2 years post menopausal)
