Intervention

Intervention type: Drug

Intervention name: Rotigotine, extended-release microspheres

Description: Four stable dose levels of LY03003 at 14, 28, 42 and 56 mg will be evaluated. For each dose level, the stable dose will be administered once a week for consecutive 5 weeks. To improve patient's tolerability, dose upward titration will be applied to 28, 42 and 56 mg dose groups according to the following schedule: Patients to be enrolled to 14 mg dose group will receive 14 mg for 5 consecutive weeks. Patients to be enrolled to 28 mg dose group will receive 14 mg in the first week and then 28 mg in the next 5 weeks. Patients to be enrolled to 42 mg dose group will receive 14 mg in the first week, 28 mg in the second week and then 42 mg in the next 5 weeks. Patients to be enrolled to 56 mg dose group will receive 14 mg in the first week, 28 mg in the second week, 42 mg in the third week and then 56 mg in the next 5 weeks.

Arm group label: LY03003

Intervention type: Drug

Intervention name: Placebo, extended-release microspheres

Description: Four stable dose levels of placebo at 14, 28, 42 and 56 mg will be evaluated. For each dose level, the stable dose will be administered once a week for consecutive 5 weeks. To improve patient's tolerability, dose upward titration will be applied to 28, 42 and 56 mg dose groups according to the following schedule: Patients to be enrolled to 14 mg dose group will receive 14 mg for 5 consecutive weeks. Patients to be enrolled to 28 mg dose group will receive 14 mg in the first week and then 28 mg in the next 5 weeks. Patients to be enrolled to 42 mg dose group will receive 14 mg in the first week, 28 mg in the second week and then 42 mg in the next 5 weeks. Patients to be enrolled to 56 mg dose group will receive 14 mg in the first week, 28 mg in the second week, 42 mg in the third week and then 56 mg in the next 5 weeks.

Criteria:

Inclusion Criteria:

- Patient had Parkinson's Disease that meet the clinical diagnostic criteria of the brain bank of the Parkinson's Disease Association of the United Kingdom.

- Patient was male or female aged 18 to 75 years;

- Patient had a Mini Mental State Examination (MMSE) score of ≥25;

- Patient had a Unified Parkinson's Disease Rating Scale (UPDRS) motor score (Part III) of ≤30 at Screening.

- Patient who signed the informed consent form volunteered to participate in this clinical trial and could cooperate with the prescribed inspections.

Exclusion Criteria:

- Patient had a history of pallidotomy, thalamotomy, deep brain stimulation, or fetal tissue transplant;

- Patient had dementia, schizophrenia or hallucinations, or clinically significant depression;

- Patient had a lifetime history of suicide attempt (including an active attempt, interrupted attempt, or aborted attempt), or presence of suicidal tendency in the past year;

- Patient had a history of orthostatic hypotension.

- Patient had received therapy with a dopamine (DA) agonist either concurrently or had done so within 28 days prior to the Screening;

- Patient had received therapy with 1 of the following drugs either concurrently or within 28 days prior to Screening: monoamine oxidase B (MAO-B) inhibitors (e.g., pargyline, selegiline), DA releasing agents (e.g., amphetamine), reserpine, DA-antagonists (e.g., metoclopramide), neuroleptics, or other medications that may interact with DA function;

- Patient was currently (at the time of Screening) receiving central nervous system active therapy (e.g., sedatives, hypnotics, antidepressants, anxiolytics), unless the dose had been stable for at least 28 days prior to Screening Visit and was likely to remain stable for the duration of the study;

- Patient had a current diagnosis of epilepsy, had a history of seizures as an adult within 1 year prior to Screening, had a history of stroke or transient ischemic attack within 3 months prior to Screening;

- Patient had a history of known intolerance/hypersensitivity to non-dopaminergic antiemetics, such as domperidone, ondansetron, tropisetron;
