Primary Outcome Measures :
- Change From Baseline in the Total "On" Time Without Troublesome Dyskinesia Based on the 2-day Average of the Self-completed Home Diary for Motor Function Status (Hauser Diary) [ Time Frame: 27 Weeks ]The Hauser diary (Hauser et al, 2000) assesses participant-defined clinical status over a period of time and provides a tool for assessment of the change in "off" time and "on" time with troublesome dyskinesia (which is a more accurate reflection of clinical response than "off" time alone). The Hauser diary asks participants to rate their mobility for each 30-minute period and to record their status for the majority of the period in 1 of 5 categories as: "on" time without dyskinesia, "on" time with nontroublesome dyskinesia, "on" time with troublesome dyskinesia, "off" time, or asleep. The total "on" time without troublesome dyskinesia will be assessed and reported at endpoint.
Secondary Outcome Measures :
- Change From Baseline in Total Daily "Off" Time Based on the 2-Day Average of the Self-Completed Home Diary for Motor Function Status (Hauser Diary) [ Time Frame: 27 Weeks ]The Hauser diary (Hauser et al, 2000) assesses participant-defined clinical status over a period of time and provides a tool for assessment of the change in "off" time and "on" time with troublesome dyskinesia (which is a more accurate reflection of clinical response than "off" time alone). The Hauser diary asks participants to rate their mobility for each 30-minute period and to record their status for the majority of the period in 1 of 5 categories as: "on" time without dyskinesia, "on" time with nontroublesome dyskinesia, "on" time with troublesome dyskinesia, "off" time, or asleep. The total daily "Off" time will be assessed and reported at endpoint.
- Change From Baseline in the Total "On" Time Without Troublesome Dyskinesia Based on the 2-day Average of the Self-completed Home Diary for Motor Function Status (Hauser Diary) [ Time Frame: Baseline, Weeks 2, 5, 8, 11, 14, 18, 22, 26, and 27 ]The Hauser diary (Hauser et al, 2000) assesses participant-defined clinical status over a period of time and provides a tool for assessment of the change in "off" time and "on" time with troublesome dyskinesia (which is a more accurate reflection of clinical response than "off" time alone). The Hauser diary asks participants to rate their mobility for each 30-minute period and to record their status for the majority of the period in 1 of 5 categories as: "on" time without dyskinesia, "on" time with nontroublesome dyskinesia, "on" time with troublesome dyskinesia, "off" time, or asleep. The total "on" time without troublesome dyskinesia will be assessed and reported at different time points.
- Change From Baseline in Total Daily "Off" Time Without Troublesome Dyskinesia Based on the 2-Day Average of the Self-Completed Home Diary for Motor Function Status (Hauser Diary) [ Time Frame: Baseline, Weeks 2, 5, 8, 11, 14, 18, 22, 26, and 27 ]The Hauser diary (Hauser et al, 2000) assesses participant-defined clinical status over a period of time and provides a tool for assessment of the change in "off" time and "on" time with troublesome dyskinesia (which is a more accurate reflection of clinical response than "off" time alone). The Hauser diary asks participants to rate their mobility for each 30-minute period and to record their status for the majority of the period in 1 of 5 categories as: "on" time without dyskinesia, "on" time with nontroublesome dyskinesia, "on" time with troublesome dyskinesia, "off" time, or asleep. The total daily "Off" time will be assessed and reported at different time points.
- Change From Baseline in the Movement Disorder Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Parts I, II and III Individual Score [ Time Frame: 27 Weeks ]The MDS-UPDRS is a multidimensional scale that assesses the motor and non-motor impacts of PD across 4 parts. Part I, non-motor aspects of experiences of daily living, comprises 13 items, 6 of which are rated by the physician (Part IA) and 7 of which are rated by the participant (Part IB). Part II, motor aspects of experiences of daily living, comprises 13 items that are rated by the participant. Part III, motor examination, comprises 18 items that are assessed by the investigator (resulting in 33 scores by location and lateralization). Part IV, motor complications, comprises 6 item (3 items for dyskinesia and 3 items for fluctuation) and requires the physician to use historical and objective information to assess dyskinesia and motor fluctuations. Each item of all the parts will be rated on a scale from 0 to 4 on which 0 = normal, 1=slight, 2=mild, 3=moderate, and 4=severe. Change from baseline in MDS-UPDRS parts I, II and III Individual score will be assessed.

- Participants who are capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the ICF and in this protocol.
- Participants with a diagnosis of PD that is consistent with the UK Parkinson's Disease Society Brain Bank diagnostic criteria, with bradykinesia and motor asymmetry.
- Participants with modified Hoehn and Yahr stage 2, 2.5, or 3 in the "on" state.
- Participants with a good response to levodopa (L-Dopa) in the judgment of the investigator.
- Participants who return a completed self-reported home diary for motor function status (Hauser diary) during the screening period (after diary training and concordance testing has occurred), with recordings for 2 consecutive days (ie, 2 consecutive 24-hour periods) showing at least 2 and half hours of "off" time on each of the 2 days.
- Participants who are on a stable dose of L-Dopa for at least 4 weeks prior to screening and are taking a minimum total daily dose of 400 milligram (mg) divided in at least 4 doses per day of standard carbidopa/levodopa or divided in at least 3 doses per day of extended-release carbidopa/levodopa capsules.
