Primary Outcome Measures:
  • Time to the need for symptomatic treatment with dopaminergic agents", defined as the number of days from the first dose of TCH346 study treatment to the date when it symptomatic treatment is required as determined by the investigator
  • Safety assessments as based on the frequency of adverse events and the number of laboratory values that fall outside of the ranges.

Secondary Outcome Measures:
  • Annual change rates for Unified Parkinsons Disease Rating Scalescore
  • Changes in UPDRS score after 4 weeks and after withdrawal of study treatment
  • Percentage of patients needing symptomatic treatment within 12 months

Enrollment: 301
Study Start Date: January 2002
Study Completion Date: November 2003
Primary Completion Date: November 2003 (Final data collection date for primary outcome measure)
