Change From Baseline (BL) in Total Awake Time Spent "Off" at Week 4 of Maintenance Period [ Time Frame: Baseline and Week 4 of the Maintenance Period (Study Week 17) ]
"Off" time is defined as the state in which the participants(par) symptoms include lack of mobility(bradykinesia) with or without additional features such as tremor or rigidity. Par were asked to record awake time "off ", awake time "on", troublesome dyskinesias(TD) during awake time "on", or time asleep for 30 minute intervals in 24 hr diary cards for 2 days preceding visits. Total number of awake hrs spent "off" per 24-hr period was the average of the 2 diary cards of the sum of awake hours spent "off" in each 24-hr diary card. BL is the last non-missing assessment measured on or before the first dose, change from BL was calculated by subtracting the BL values from the MP Week 4 values. Mixed Model Repeated Measures (MMRM) model used BL total awake time 'Off', treatment, visit and treatment by visit
Patient reported awake time "off", measured in hours. [ Time Frame: Week 4 of the maintenance period ]
The general definition of "off" includes a lack of mobility (bradykinesia) with or without additional features such as tremor or rigidity. The primary analysis is based on change from baseline in total awake time "off", measured in hours.

  • Responder Rate Defined as the Percentage of Participants With a 20% Reduction in Baseline (BL) "Off" Time at Week-4 of Maintenance Period [ Time Frame: Week 4 of the Maintenance Period (Study Week 17) ]
    The responder rate was defined as the percentage of par with greater than or equal to (>=) 20 percent (%) reduction in their individual BL "off" time at Week 4 of the Maintenance Period. The "off" time is defined as the state in which the participants' symptoms include lack of mobility (bradykinesia) with or without additional features such as tremor or rigidity. BL is defined as the last non-missing assessment measured on or before the first dose date. Responder Rate (Least Squares [LS] means on inverse linked scale), odds ratio with 95% CI and p-value comparing against placebo were estimated by Generalized Estimating Equations (GEE) model. Baseline total awake time 'Off', treatment, visit and treatment*visit are included in the model.
  • Percentage of Participants With a >=1 Hour Reduction in Baseline "Off" Time at Week 4 of the Maintenance Period [ Time Frame: Baseline and Week 4 of the Maintenance Period (Study Week 17) ]
    The "off" time is defined as the state in which the participants' symptoms include lack of mobility (bradykinesia) with or without additional features such as tremor or rigidity. BL is defined as the last non-missing assessment measured on or before the first dose date. The percent change from BL was calculated by subtracting the BL values from the Maintenance Period Week 4 values. Percentage of participants meeting the criterion (LS mean on inverse linked scale), odds ratio with 95% CI and p-value comparing against placebo were estimated by Generalized Estimating Equations (GEE) model. Baseline 'off-time', treatment, visit and treatment*visit are included in the model.
  • Percentage of Participants With a >=2 Hours Reduction in Baseline "Off" Time at Week 4 of the Maintenance Period [ Time Frame: Baseline and Week 4 of the Maintenance Period (Study Week 17) ]
    The "off" time is defined as the state in which the participants' symptoms include lack of mobility (bradykinesia) with or without additional features such as tremor or rigidity. BL is defined as the last non-missing assessment measured on or before the first dose date. The percent change from BL was calculated by subtracting the BL values from the Maintenance Period Week 4 values. Percentage of participants meeting the criterion (LS mean on inverse linked scale), odds ratio with 95% CI and p-value comparing against placebo were estimated by Generalized Estimating Equations (GEE) model. Baseline 'off-time', treatment, visit and treatment*visit are included in the model.
  • Responder Rate According to the Clinical Global Impression-global Improvement (CGI-I) Scale at Week 4 of the Maintenance Period [ Time Frame: Week 4 of the Maintenance Period (Study Week 17) ]
    The CGI-I scale allows the investigator to rate the participant's total improvement since the beginning of treatment (Baseline). Baseline is defined as the last non-missing assessment measured on or before the first dose date. The scale is rated from 1-7 where 1 = "very much improved", 2 = "much improved", 3 = "minimally improved", 4 = "no change", 5 = "minimally worse, 6 = "much worse", and 7 = "very much worse". The responder rate is defined as the percentage of participants with a score of 1 or 2. The Generalized Estimating Equations (GEE) model was used to determine CGI responder rate with treatment, visit, and treatment by visit interaction included in the model. Only scheduled visits were included.

    The UPDRS is a clinician based rating scale used to measure motor impairments and disability. The UPDRS assesses six features of PD impairment. These are evaluated using a combination of data collected by interview and examination of the par.. One of the six features include the Part III-motor examination where scores can range 0 to 108 with par. in an "on" state where the maximum score indicates the worse condition. BL is defined as the last non-missing assessment measured on or before the first dose date. The change from BL was calculated by subtracting the BL values from the Maintenance Period Week 4 values.

Test were performed when the par. is in the "on" state of PD. BL is defined as the last non-missing assessment measured on or before the first dose date. The change from BL was calculated by subtracting the BL values from the Maintenance Period Week 4 values. LS means, 95% CIs and P-values were estimated from MMRM.

This component of the UPDRS is the total score for 4 items (the items 1 to 4 include intellectual impairment, thought disorder, motivation / initiative, and depression) and may have a value ranging from 0 to 16 as determined by a physician. The higher score (16) indicates the maximum score and the worse condition. All 4 items have to be present for a total score to be calculated. If one or more items are missing, the total score for the component would also be missing. BL is defined as the last non-missing assessment measured on or before the first dose date. The change from BL was calculated by subtracting the BL values from the individual post-randomization values. LS means, 95% CIs and P-values were estimated from MMRM.

A Fixed Dose Study of Ropinirole Prolonged Release as Adjunctive Treatment in Patients With Advanced Parkinson's Disease
A Fixed Dose, Dose-response Study of Ropinirole Prolonged Release (PR) as Adjunctive Treatment to L-dopa in Patients With Advanced Parkinson's Disease
This is a double blind, fixed dose, parallel group study to characterize the dose response of ropinirole PR as adjunctive therapy to L-dopa in patients with late stage Parkinson's disease. The primary endpoint of this study, mean change from baseline in total awake time spent "off' is the same endpoint as used in the ropinirole PR pivotal study for advanced Parkinson's disease patients. This study includes a wide range of ropinirole doses (4-24mg) with the 8mg, 12mg, and 16mg per day doses powered to detect a 1.7 hour difference in total awake time spent "off" compared with placebo. The dose of Ldopa will remain stable through the study, unless the subject experiences tolerability issues that require an L-dopa dose reduction. Up to three L-dopa dose reductions are allowed, making a total reduction of up to approximately 30%. Keeping the L-dopa dose constant where possible is important to avoid confounding the efficacy data. Clinical review of the primary and secondary endpoints will be performed in order to establish the lowest maximally effective therapeutic dose.
