Inclusion Criteria:

• Idiopathic Parkinson's disease (PD) according to United Kingdon Parkinson's Disease Society (UKPDS) Brain Bank Criteria
• Levodopa-responsive with severe motor fluctuations
• Completion of protocol S187.3.001 (NCT00357994) or S187.3.002 (NCT00660387) and continue to meet the inclusion criteria for the preceding study
