A Post Marketing Observational Study of Activities of Daily Living in Advanced Parkinson's Disease Patients With Early Troublesome Motor Fluctuations and Treated With Duodopa - a Multi-country Study

Study Overview
=================
Brief Summary
-----------------
Patients with advanced Parkinson's Disease experience a range in the severity of their motor fluctuations. The rationale for this Post Marketing Observational Study is to demonstrate the benefits of Duodopa treatment on Parkinson's Disease patients entering the advanced stage of the disease whose motor fluctuations have become troublesome and complicate management with oral therapy. The aim of this post-marketing observational study is to assess the effect of Duodopa treatment on activities of daily living in advanced Parkinson's Disease participants characterised by either 2-4 hours of off time or 2 hours of non-troublesome or troublesome dyskinesia daily, supported by a Unified Parkinson's Disease Rating Scale Total Score in the best on state of at least 40 points at baseline.

Detailed Description
-----------------
Data are recorded from visits most closely aligned with the planned periods of Visit 0 (V0): Baseline (After decision to use the temporary naso-duodenal tube (approximately 2-14 days) and after signature of the Patient Authorization/Informed Consent Form); Visit 1 (V1): At discharge from hospital; Visit 2 (V2): 3 months after discharge; Visit 3 (V3): 6 months after discharge; Visit 4 (V4): 12 months after discharge. All participants have a temporary naso-duodenal tube used initially with the infusion pump to determine if the participant responds favorably to this method of treatment and to optimize the dose of Duodopa before permanent treatment is started. Participants who choose a treatment other than Duodopa after the temporary naso-duodenal test phase are considered for the Standard of Care group. Participants who go on to select Apomorphine pump or Deep Brain Stimulation at any stage are not eligible to continue in this group or to continue in the observational period of study. Participants who continue to with Duodopa treatment after the the temporary naso-duodenal test phase are the Duodopa group.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Unified Parkinson's Disease Rating Scale (UPDRS) II (Activities of Daily Living) Score: Mean Change From Baseline to 12 Months After Hospital Discharge | The UPDRS is an Investigator-used rating tool to follow the longitudinal course of Parkinson's disease. The Part II score is the sum of the answers to 13 questions, each of which are measured on a 5-point scale (0-4). The Part II score ranges from 0-52 and higher scores are associated with more disability. UPDRS scores during On time (when PD symptoms are well controlled by the drug) are presented. Last observation carried forward (LOCF) was used for missing data. | Baseline (Week 0) and 12 months after hospital discharge | 

Secondary Outcome Measures

| Unified Parkinson's Disease Rating Scale (UPDRS) III (Motor Examination) Score: Mean Change From Baseline to 3, 6, and 12 Months After Hospital Discharge | The UPDRS III questionnaire consists of 14 questions on motor examinations rated from 0 (absent/normal) to 4 (extreme impairment). Questions 20-26 are multi-part questions in that they are evaluated separately for multiple body parts (for example, for the left and right hand). Counting each of these assessments leads to a total of 27 answers. The UPDRS III score ranges from 0 to 108 with higher values indicating greater impairment and was calculated as the sum of the 27 answers provided to the 14 questions. Observed values are presented for each visit as well as LOCF at 12 months after discharge. n=the number of participants with data at baseline and given time point. | Baseline (Week 0) and 3, 6, and 12 months after hospital discharge | 
| Non-Motor Symptoms Assessment Scale for Parkinson's Disease (NMSS Rating Scale) Total Score: Mean Change From Baseline to 3, 6, and 12 Months After Hospital Discharge | Non-motor symptoms assessed over the previous month were scored with respect to severity (0 = none, 1 = mild, 2 = moderate, 3 = severe) and with respect to frequency (1 = rarely, 2 = often, 3 = frequent, 4 = very frequent). The total NMSS score ranges from 0 to 360 with higher values indicating greater impairment and was calculated as the sum of all individual score values. Observed values are presented for each visit as well as LOCF at 12 months after discharge. n=the number of participants with data at baseline and given time point. | Baseline (Week 0) and 3, 6, and 12 months after hospital discharge |
