Study Overview
Brief Summary
The purpose of this study is to provide long-term safety data for rivastigmine capsule and transdermal patch treatments, in particular the effect of rivastigmine on worsening of the underlying motor symptoms of Parkinson's Disease (PD), in patients with mild to moderately severe dementia associated with PD.

Arms & Interventions
Rivastigmine capsule
Rivastigmine capsules starting at a total dose of 3 mg/day (1.5 mg twice daily orally) titrated up in 3 mg/day increments every 4 weeks to a final dose of 12 mg/day (6 mg twice daily orally). The 12 mg/day dose or the highest dose tolerated was maintained until week 76.
Intervention: Rivastigmine capsule (Drug)
Rivastigmine patch
Rivastigmine patch once a day in the morning, worn for 24 hours, starting at 5 cm^2 (delivering 4.6 mg rivastigmine over a 24 hour period) for 4 weeks then titrated up to 10 cm^2 daily (delivering 9.5 mg rivastigmine over a 24 hour period). The 10 cm^2 patch or the highest well tolerated dose was maintained until week 76.
Intervention: Rivastigmine transdermal patch (Drug)
Outcomes
Primary Outcomes
Percentage of Participants With Adverse Events (AEs) Due, or Potentially Due, to Worsening of Parkinson Disease (PD) Motor Symptoms (Tremor, Muscle Rigidity, Bradykinesia, Fall)
Time Frame: 76 Weeks
The AEs were summarized by presenting the number and percentage of patients having any of the 4 AEs or discontinued due to any of the 4 predefined AEs (tremor, muscle rigidity, bradykinesia, and fall)in each treatment group. The 95% CIs associated with the rates were also presented.
Percentage of Participants With Study Drug Discontinuations Due to Predefined AEs That Are Due, or Potentially Due, to Worsening of PD Motor Symptoms (Tremor, Muscle Rigidity, Bradykinesia, Fall)
Time Frame: 76 Weeks
The discontinuations due to these AEs were summarized by presenting the number and percentage of patients having any of the 4 AEs or discontinued due to any of the 4 predefined AEs (tremor, muscle rigidity, bradykinesia, and fall) in each treatment group. The 95% CIs associated with these rates were also presented.

- Change in Mattis Dementia Rating Scale (Mattis DRS-2) Scores at Weeks 16, 24, 52 and 76 Compared to Baseline(From Baseline to Weeks 16, 24, 52 and 76)
- Change in Ten Point Clock Test (TPCT) Scores at Weeks 16, 24, 52 and 76 (or Early Discontinuation) Compared to Baseline(From Baseline to Weeks 16, 24, 52 and 76)
- Change in Neuropsychiatric Inventory-10 (NPI-10) Scores at Weeks 16, 24, 52 and 76 (or Early Discontinuation) Compared to Baseline(At Week 16, 24, 52 and 76 (or early discontinuation))
- Change in Alzheimer's Disease Cooperative Study-Activities Of Daily Living (ADCS-ADL) Scores at Weeks 16, 24, 52 and 76 (or Early Discontinuation) Compared to Baseline(From Baseline to Week 16, 24, 52 and 76 (or early discontinuation))
- UPDRS Part V Stage (Modified Hoehn and Yahr Staging)at Baseline, Week 8,16,24,52 and 76 (or Early Discontinuation)(From Baseline to Week 8, 16, 24, 52 and 76 (or early discontinuation))
