A Dose-finding Study for SPM 962 in Advanced Parkinson's Disease Patients

The primary objective of this study is to investigate efficacy and safety of SPM 962 in advanced Parkinson's Disease (PD) patients in a multi-center, placebo-controlled study following once-daily multiple transdermal doses of SPM 962 within a range of 4.5 to 36.0 mg (12 weeks of dose titration/maintenance period). Recommended maintenance dose range is also to be investigated with distribution of the maintenance dose and accumulated response rate of efficacy.

Primary outcomes

  1. Unified Parkinson's Disease Rating Scale (UPDRS) Part 3 Sum Score

    Time frame: baseline, 12 weeks after dosing

    Mean change (LOCF) from baseline in UPDRS Part 3 sum score at 12 weeks after dosing.

    UPDRS is a scale for monitoring Parkinson's Disease-related disability and impairment. The UPDRS consists of the following four sub-scales. Part 1: Mentation, Part 2: Activities of Daily Living, Part 3: Motor, Part 4: Complications. Part 3 assesses 14 items. Each item is scored from 0 (normal) to 4 (severe). The sum score serves as the sub-scale score. A higher score indicates a greater severity of symptoms. Thus a decrease in the scores means improvement.

Secondary outcomes

  1. UPDRS Part 2 Sum Score (Average Score of on State and Off State)

    Time frame: baseline, 12 weeks after dosing

    Mean change (LOCF) from baseline in UPDRS Part 2 sum score (average scores of on state and off state) at 12 weeks after dosing.

    Mean change (LOCF) from baseline in UPDRS Part 2 sum score (average score of on state and off state) at 12 weeks after dosing.

    UPDRS sub-scale Part 2 assesses 13 items. Each item is scored from 0 (normal) to 4 (severe). The sum score serves as the sub-scale score. A higher score indicates a greater severity of symptoms. Thus a decrease in the scores means improvement.

  2. Off Time

    Time frame: baseline, 12 weeks after dosing

    Mean change (LOCF) from baseline in off time at 12 weeks after dosing.

  3. Effective Rate in UPDRS Part 3 Sum Score

    Time frame: Baseline, 12 weeks after dosing

    Effective rate (percentage of subjects with 20% or 30% decrease) (LOCF) in UPDRS Part 3 sum score at 12 weeks after dosing.

  4. UPDRS Part 1 Sum Score

    Time frame: Baseline, 12 weeks after dosing

    Mean change (LOCF) from baseline in UPDRS Part 1 sum score at 12 weeks after dosing.

    UPDRS sub-scale Part 1 assesses 4 items. Each item is scored from 0 (normal) to 4 (severe). The sum score serves as the sub-scale score. A higher score indicates a greater severity of symptoms. Thus a decrease in the scores means improvement.

  5. Effective Rate in Off Time

    Time frame: Baseline, 12 weeks after dosing.

    Effective rate (percentage of subjects with 20% or 30% decrease) (LOCF) in off time at 12 weeks after dosing.

  6. UPDRS Part 2 Sum Score (on State)

    Time frame: Baseline, 12 weeks after dosing

    Mean change (LOCF) from baseline in UPDRS Part 2 sum score (on state) at 12 weeks after dosing.

    UPDRS sub-scale Part 2 assesses 13 items. Each item is scored from 0 (normal) to 4 (severe). The sum score serves as the sub-scale score. A higher score indicates a greater severity of symptoms. Thus a decrease in the scores means improvement.

  7. UPDRS Part 2 Sum Score (Off State)

    Time frame: Baseline, 12 weeks after dosing

    Mean change (LOCF) from baseline in UPDRS Part 2 sum score (off state) at 12 weeks after dosing.

    UPDRS sub-scale Part 2 assesses 13 items. Each item is scored from 0 (normal) to 4 (severe). The sum score serves as the sub-scale score. A higher score indicates a greater severity of symptoms. Thus a decrease in the scores means improvement.

  8. UPDRS Part 4 Sum Score

    Time frame: Baseline, 12 weeks after dosing

    Mean change (LOCF) from baseline in UPDRS Part 4 sum score at 12 weeks after dosing.

    UPDRS sub-scale Part 4 assesses 11 items. Each item is scored from 0 (normal) to 4 (severe). The sum score serves as the sub-scale score. A higher score indicates a greater severity of symptoms. Thus a decrease in the scores means improvement.

  9. Total of UPDRS Part 2 Sum Score (Average Score of on State and Off State) and UPDRS Part 3 Sum Score

    Time frame: Baseline, 12 weeks after dosing

    Mean change (LOCF) from baseline in total of UPDRS Part 2 sum score (average score of on state and off state), and UPDRS Part 3 sum score at 12 weeks after dosing.

    UPDRS sub-scale Part 2 assesses 13 items and Part 3 assesses 14 items. Each item is scored from 0 (normal) to 4 (severe). The sum score serves as the sub-scale score. A higher score indicates a greater severity of symptoms. Thus a decrease in the scores means improvement.

  10. Total of UPDRS Part 1 Sum Score, UPDRS Part 2 Sum Score (Average Score of on State and Off State), UPDRS Part 3 Sum Score, and UPDRS Part 4 Sum Score.

    Time frame: Baseline, 12 weeks after dosing

    Mean change (LOCF) from baseline in total of UPDRS Part 1 sum score, UPDRS Part 2 sum score (average score of on state and off state), UPDRS Part 3 sum score, and UPDRS Part 4 sum score at 12 weeks after dosing.

    UPDRS sub-scale Part 1, 2, 3, and 4 assess 4, 13, 14, and 11 items respectively. Each item is scored from 0 (normal) to 4 (severe). The sum score serves as the sub-scale score. A higher score indicates a greater severity of symptoms. Thus a decrease in the scores means improvement.

  11. The Modified Hoehn & Yahr Severity of Illness

    Time frame: Baseline, 12 weeks after dosing

    Mean change (LOCF) from baseline in the Modified Hoehn & Yahr Severity of Illness at 12 weeks after dosing.

    The Modified Hoehn & Yahr criteria are measured on the following 8-point scale for staging: 0, No signs of disease; 1, Unilateral disease; 1.5, Unilateral plus axial involvement; 2, Bilateral disease without impairment of balance; 2.5, Mild bilateral disease with recovery on pull test; 3, Mild to moderate bilateral disease, some postural instability, physically independent 4, Severe disability, still able to walk or stand unassisted; and 5, Wheelchair bound or bedridden unless aided.
