| Primary | Mean Change From Week 0 (Baseline) in the Japanese Unified Parkinson's Disease Rating Scale (UPDRS) Part III Total Score at the Final Assessment Point (FAP) (up to Week 24) in the Non-Inferiority Verification Phase | The Japanese UPDRS assesses the status of Parkinson's Disease (PD) patients objectively. Part III assesses motor examination on 27 items. Participants receive a score of 0-4 points per item. The maximum total score is 108 points. A higher score indicates more severe PD symptoms. Mean change from Week 0 was calculated as the total score at FAP minus the total score at Week 0. Participants who withdrew before Week 2 and who had only one observation for the part III total score were not included in the analysis. | Per Protocol Set (PPS): participants with exclusion from the Full Analysis Set (FAS) of those violating the study protocol and assessed to be excluded from the assessment of drug efficacy. On-treatment last observations within the phase were carried forward as FAP values of the phase. FAP values do not include values of Weeks 0, 1, and 2. | Posted | | Mean | Standard Deviation | scores on a scale | | Week 0 and FAP (up to Week 24) | | | | ID | Title | Description |

| OG000 | Ropinirole PR-Ropinirole PR | Participants received ropinirole prolonged release/extended release (PR/XR) tablets orally once daily. Participants firstly received matching PR/XR placebo tablets for 2 weeks and then received 2 milligram (mg) PR/XR tablets with a weekly dose increase to 4 mg at Week 4. Between Weeks 6 and 24, the dose was optionally increased at intervals of 2 weeks or longer up to 16 mg/day. In the PR/XR Switching Phase, administration of the PR/XR tablets was continued until Week 32 at the same dose level as that at the end of the Non-Inferiority Verification Phase. Participants who entered into the Long-term Phase continued to receive ropinirole PR/XR tablets until Week 54 at the same dose level as that at the end of the PR/XR Switching Phase. Participants who did not enter the Long-term Phase entered the Down-titration Phase after completion of the PR/XR Switching Phase. | | OG001 | Ropinirole IR-Ropinirole PR | Participants received ropinirole immediate release (IR) tablets three times daily at the initial dose of 0.75 mg/day with a weekly dose increase to 3 mg/day at Week 4. Between Weeks 6 and 24, the dose was optionally increased at intervals of 2 weeks or longer up to 15 mg/day. Ropinirole IR tablets were administered until the night of the Week 24 visit and were replaced by ropinirole PR/XR tablets on the following morning, the morning of the first day of the PR/XR Switching Phase, at the same dose level. Participants who entered the Long-term Phase continued to receive ropinirole PR/XR until Week 54 at the same dose level as that at the end of the PR/XR Switching Phase.
