What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of participants experiencing adverse events (AE) and serious adverse events (SAE)

    All AEs and SAEs will be assessed following National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) version 6.0.

    Measured: From Day 1 to Week 76

Secondary outcomes (15)
  1. Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III score

    MDS-UPDRS Part III is a scale used by the investigator to evaluate motor functions of Parkinson's disease. The total score ranges from 0 to 132. The higher score indicates more difficulties with movements.

    Measured: Baseline to Week 72

  2. MDS-UPDRS Part IV score

    MDS-UPDRS Part IV is a scale used by the investigator to evaluate the motor complications in Parkinson's disease. The total score ranges from 0 to 24 with the higher score indicating greater impact on the daily life due to motor complications.

    Measured: Baseline to Week 72

  3. Sum of MDS-UPDRS Part I score, MDS-UPDRS Part II score and MDS-UPDRS Part III score

    • MDS-UPDRS Part I is a scale, consisting of Part IA (conducted by healthcare professionals) and Part IB (participant's self-assessment), to assess how non-motor symptoms impact daily living. The total score ranges from 0 to 52. The higher score indicates more non-motor symptoms or greater impact on the activities of daily living due to non-motor symptoms.
    • MDS-UPDRS Part II is a participant's self-assessment to observe how motor symptoms affect your daily living. The total score ranges from 0 to 52. The higher score indicates more motor symptoms or greater impact on the activities of daily living.
    • MDS-UPDRS Part III is a scale used by the investigator to evaluate motor functions of Parkinson's disease. The total score ranges from 0 to 132. The higher score indicates more difficulties with movements.

    Measured: Baseline to Week 72

  4. Proportion of participants with 3-point or more increase in MDS-UPDRS Part III score

    MDS-UPDRS Part III is a scale used by the investigator to evaluate motor functions of Parkinson's disease. The total score ranges from 0 to 132. The higher score indicates more difficulties with movements.

    Measured: Baseline to Week 72

  5. Time to onset of motor complication

    The motor complication events are collected from the MDS-UPDRS Part IV, a scale to evaluate the motor complication in Parkinson's disease. The total score ranges from 0 to 24 with the higher score indicating greater impact on the daily life due to motor complications.

    Measured: From Day 1 to Week 72

  6. Non-motor symptoms scale (NMSS) total score

    NMSS is a scale to assess non-motor symptoms in Parkinson's disease. It contains 9 subdomains and the total score ranges from 0 to 360. The higher score indicates greater burden of non-motor symptoms.

    Measured: Baseline to Week 72

  7. Parkinson's Disease Questionnaire-39 (PDQ-39) total score

    PDQ-39 score is to assess the health-related quality of life with Parkinson's disease. The total score is transformed into a percentage score between 0 to 100 with higher percentage indicating worsen health-related quality of life due to Parkinson's disease.

    Measured: Baseline to Week 72

  8. Modified Hoehn and Yahr stage

    Modified Hoehn and Yahr stage is a scale to evaluate severity of Parkinson's disease in 8 stages. The staging ranges from Stage 0 (No sings of disease) to Stage 5 (Wheelchair bound or bedridden unless aided).

    Measured: Baseline to Week 72

  9. Levodopa equivalent daily dose (LEDD) of antiparkinsonian medications

    The doses of antiparkinsonian medications will be converted into levodopa equivalent daily dose (LEDD, mg).

    Measured: Baseline to Week 72

  10. Time to the first LEDD adjustment

    It refers to the changes in LEDD amount (defined as a ≥10% change in LEDD).

    Measured: From Day 1 to Week 72

  11. Number of participants with abnormalities in vital signs

    Vital signs measurement consist of systolic and diastolic blood pressure, respiratory rate, pulse rate, and body temperature.

    Measured: Baseline to Week 76
