Treatment and study plan

Rotigotine

Drug

Patches will contain 4 mg / 24 h (20 cm^2), 6 mg/ 24 h (30 cm^2), or 8 mg /24 h (40 cm^2) of Rotigotine. Application of study medication starts at the Baseline Visit. Rotigotine will be administered once daily starting at 4 mg / 24 h. Doses will then be up-titrated in weekly increments of 2 mg / 24 h until optimal or maximum dose (16 mg / 24 h) is reached and the Maintenance Period can be started. The duration of the Titration Period will vary from 1 to 7 weeks ± 3 days. The Maintenance Period will last 12 weeks ± 5 days. Thereafter, during the De-escalation Period, the dose of study medication will be decreased by 2 mg / 24 h every other day. The De-escalation Period may last up to 12 days.

Other names: (6S)-6-propyl-[2 (2 thienyl)ethyl]amino-5,6,7,8-tetrahydro-1-naphthalenol

Placebo

Drug

Placebo patches match the size of active patches 20 cm^2, 30 cm^2, or 40 cm^2 and will contain Placebo. Application of Placebo patches starts at the Baseline Visit. Placebo patches will be administered once daily starting with the equivalent of 4 mg / 24 h. Doses will then be up-titrated in weekly equivalents to 2 mg / 24 h until either optimal dose or maximum dose is reached. The maximum dose is the equivalent to 16 mg / 24 h. The duration of the Titration Period will vary from 1 to 7 weeks. The Maintenance Period will last 12 weeks ± 5 days. During the De-escalation Period, the dose of Placebo will be decreased by the equivalent to 2 mg / 24 h every other day. The De-escalation Period may last up to 12 days.

Primary outcomes

  1. Change From Baseline to the End of the Maintenance Period in Pain Severity Assessed Using an 11-point Likert Pain Scale

    Time frame: Baseline (Visit 2) until End of the Maintenance Period (Maintenance Period lasts 12 weeks ± 5 days after an up to 7 weeks Titration Period)

    An 11-Point Likert Scale was used to assess patients' average daily pain. The subject rated his/her average pain from 0 (no pain) to 10 (worst pain ever experienced).

    The average pain experienced in the last 7 days was calculated by the mean of the daily Likert Pain Scores within the 7 days prior to the respective visit (ie, Likert Pain Scores with a date of assessment before the date of visit and on or after the date of visit - 7 days). A negative value indicates an improvement.

Secondary outcomes

  1. Percentage of Responders at the End of the Maintenance Period

    Time frame: Baseline (Visit 2) until End of the Maintenance Period (Maintenance Period lasts 12 weeks ± 5 days after up to 7 weeks Titration Period)

    Responders are defined as patients experiencing a 2-Point or more Reduction on an 11-Point Likert Pain Scale from Baseline to the End of the Maintenance Period. An 11-Point Likert Scale was used to assess patients' average daily pain. The patient rated his/her average pain from 0 (no pain) to 10 (worst pain ever experienced).

  2. Change From Baseline to the End of the Maintenance Period in the Sum Score of the 8-Item Parkinson's Disease Questionnaire (PDQ-8)

    Time frame: Baseline (Visit 2) until End of the Maintenance Period (Maintenance Period lasts 12 weeks ± 5 days after up to 7 weeks Titration Period)

    The 8-Item Parkinson's Disease Questionnaire (PDQ-8) (Peto et al, 1998) is a self-administered questionnaire that provides a reliable measure of overall health status. The PDQ-8 contains 8 items of daily living, with 1 item selected from each of the following 8 scales: mobility, Activities of Daily Living (ADL), emotional well being, stigma, social support, cognitions, communication, and bodily discomfort. The total PDQ-8 score is the sum of all the individual items converted to a summary index score between 0 and 100, with lower scores indicating better health. A negative value indicates an improvement.

  3. Change From Baseline to the End of the Maintenance Period in the 7-Item Depression Subscore of the Hospital Anxiety and Depression Scale (HADS)

    Time frame: Baseline (Visit 2) until End of the Maintenance Period (Maintenance Period lasts 12 weeks ± 5 days after up to 7 weeks Titration Period)

    The Hospital Anxiety and Depression Scale (HADS) (Zigmond and Snaith, 1983) is a 14-item self-assessment scale for detecting states of depression and anxiety in the setting of a hospital medical outpatient clinic. It comprises a 7-item anxiety subscale and a 7-item depressive subscale that are also measures of severity of the emotional disorder. The 14 items are scored between 0 and 3. The 7-item depression subscore and 7-item anxiety subscore were calculated as the sum of the 7 corresponding individual scores. A negative value indicates an improvement.

  4. Change From Baseline to the End of the Maintenance Period in the 7-Item Anxiety Subscore of the Hospital Anxiety and Depression Scale (HADS)

    Time frame: Baseline (Visit 2) until End of the Maintenance Period (Maintenance Period lasts 12 weeks ± 5 days after up to 7 weeks Titration Period)

    The Hospital Anxiety and Depression Scale (HADS) (Zigmond and Snaith, 1983) is a 14-item self-assessment scale for detecting states of depression and anxiety in the setting of a hospital medical outpatient clinic. It comprises a 7-item anxiety subscale and a 7-item depressive subscale that are also measures of severity of the emotional disorder. The 14 items are scored between 0 and 3. The 7-item depression subscore and 7-item anxiety subscore were calculated as the sum of the 7 corresponding individual scores. A negative value indicates an improvement.

  5. Change From Baseline to the End of the Maintenance Period in the Combined Score of the Unified Parkinson's Disease Rating Scale (UPDRS) Parts II (Activities of Daily Living [ADL] Subscale) and III (Motor Subscale)

    Time frame: Baseline (Visit 2) until End of the Maintenance Period (Maintenance Period lasts 12 weeks ± 5 days after up to 7 weeks Titration Period)

    Part II of the Unified Parkinson's Disease Rating Scale (UPDRS) assesses the subject's activities of daily living. Part III assesses motor function. The UPDRS is completed by questioning the subject about his/her general state in conjunction with any observations made by the investigator (or designee) since the previous visit. Part II is subject-rated and Part III is physician-rated. The UPDRS Part II (Activities of Daily Living) consists of 13 items scored between 0 and 4. The sum score was calculated as the sum of these 13 individual scores. The UPDRS Part III (motor subscale) consists of 27 items and sub items scored between 0 and 4. The sum score was calculated as sum of these 27 individual scores. The sum score of UPDRS Parts II and III is the sum of the corresponding single sum scores. A negative value indicates an improvement.

  6. Change From Baseline to the End of the Maintenance Period in the 7 Domain Scores of Classification of Pain in Parkinson's Disease

    Time frame: Baseline (Visit 2) until End of the Maintenance Period (Maintenance Period lasts 12 weeks ± 5 days after up to 7 weeks Titration Period)

    The classification of pain in Parkinson's disease scale classifies pain in the following domains: musculoskeletal pain (item 1), chronic pain (items 2 and 3), fluctuation related pain (items 4, 5 and 6), nocturnal pain (items 7 and 8), oro-facial pain (items 9, 10 and 11), discoloration; edema/swelling (items 12 and 13), and radicular pain (item 14). Severity of the pain is measured on a scale from none (0) to severe (3) and frequency is measured on a scale from never (0) to very frequent (4).

    A score of a single item was calculated by multiplying severity with frequency. A domain score was calculated as the sum of every individual score related to the respective domain. A negative value indicates an improvement.
