Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Safinamide
Patient will receive film-coated Safinamide tablets orally at an initial dose of 50 mg once daily (OD) and then will be increased the day after the Visit 3/week 2 (ideally at day 15) to the final dose of 100 mg OD.
Treatment will continue daily for a total of 16 weeks.
|
At baseline (Day 1), eligible patients will be randomised to receive safinamide (initial 50 mg titrated to 100 mg the day after the Visit 3/week 2, ideally at day 15).
The investigational medicinal product (IMP) will be taken in the morning at breakfast time, in addition to the morning dose of L-dopa and other (if any) PD medications.
|
Placebo Comparator: Placebo
Patient will receive matching placebo orally at an initial dose of 50 mg once daily (OD) and then will be increased the day after the Visit 3/week 2 (ideally at day 15) to the final dose of 100 mg OD.
Treatment will continue daily for a total of 16 weeks.
|
At baseline (Day 1), eligible patients will be randomised to receive matching placebo, orally OD.
Placebo will be added to the standard stabilized treatment as a control of the safinamide group, hence patients on placebo will have benefit from other ongoing anti-PD medication

Measure Description |
Time Frame |

Change From Baseline to Week 16 in the Mean Total Daily "OFF" Time
Time Frame: At baseline and Week 16
|
The mean total daily "OFF" time was assessed by 24-hour patient diary cards, of safinamide 100 mg/day compared to placebo, given as add-on therapy in PD patients with motor fluctuations on stable doses of L-dopa. Patients completed the daily diary by selecting one of the following five options for each 30-minute time period:

Time Frame |
---|---|---|
Change From Baseline to Week 16 in Pain Severity, as Assessed by an 11 Point Numerical Rating Scale (NRS)
Time Frame: At baseline and Week 16
|
The pain severity, was assessed by an 11-point Numerical Rating Scale (NRS).
The NRS is a segmented numeric version of the visual analogue scale (VAS) in which a patient selects a whole number that best reflects the intensity of his/her pain, ranging from '0' ("no pain") to '10' ("worst possible pain").
|
At baseline and Week 16
|
Change From Baseline to Week 16 in the Mean Total Daily "ON" Time
Time Frame: At baseline and Week 16
|
The mean total daily "ON" time, as assessed by 24-hour patient diary cards. Patients completed the daily diary by selecting one of the following five options for each 30-minute time period:
|
At baseline and Week 16
|
Change From Baseline to Week 16 in the Mean Daily "ON" Time With no/Non Troublesome Dyskinesia
Time Frame: At baseline and Week 16
|
The mean daily "ON" time with no/non troublesome dyskinesia, as assessed by 24-hour patient diary cards. Patients completed the daily diary by selecting one of the following five options for each 30-minute time period:
|
At baseline and Week 16
|
Change From Baseline to Week 16 in the Unified Parkinson's Disease Rating Scale (UPDRS) Total Score During the "ON" Phase
Time Frame: At baseline and Week 16
|
The UPDRS comprises 3 parts that evaluates any complication of treatment: Part I: Evaluation of mentation or cognition, behavior and mood.
Part II: Evaluation of the activities of daily life.
Part III: Evaluation of motor function.
Part IV: Evaluation of complications of therapy.
The UPDRS performed by the Investigator with points assigned to each item in the scale based on the patient's response as well as observation and physical examination.
Together Parts I-III contain 44 items, with each item scored on a 5-point scale.
Part IV contains 11 questions with a scale ranging from 0 to 23.
Thus, the final total score may range from 0 (no disability) to 199 (total disability).
The UPDRS is the most commonly used scale in clinical studies to follow the longitudinal course of PD.
Part I Evaluation of mentation or cognition, behavior and mood contains 4 items with each item scored on a 5 point scale, the scale ranging from 0 to 16.
|
At baseline and Week 16
|
Change From Baseline to Week 16 in the UPDRS Part II Activities of Daily Living (ADL) Score During the "ON" Phase
Time Frame: At baseline and Week 16
|
The UPDRS= Unified Parkinson's Disease Rating Scale; is the most commonly used scale in clinical studies to follow the longitudinal course of PD. It is divided in 4 sections, each of them with several items. The score of each item is 0-1 or 0-4 (the majority) where 0 is no symptom while the highest score means the most severe symptom. UPDRS part I: 4 items, score 0-16 (total); UPDRS part II: 13 items, score 0-52 (total); UPDRS part III: 14 items, score 0-108 (total) UPDRS part IV: it is dived in 3 sections. Section A=dyskinesias, 4 items, score 0-13 (total); section B=clinical fluctuations, 4 items, score 0-7 (total); section C=other complications, 3 items, score 0-3 (total). The total score of the UPDRS (meaning of all the 4 parts) is 0-199 where 0 means no symptoms, 199 the most severe symptoms. |

At baseline and Week 16
|
Clinical Global Impression of Severity (CGI-S) Score Assessed at Week 16
Time Frame: At week 16
|
The CGI-S scale measures global severity of illness at a given point in time.
It is rated on a 7-point Likert-type scale ranging from 1 (normal, not ill at all) to 7 (extremely severe).
The CGI-S was assessed at all visits, starting at baseline.
|
At week 16
|
Clinical Global Impression of Change (CGI-C) Assessed at Week 16
Time Frame: At baseline and Week 16
|
The CGI-C scale measured the change in the patient's clinical status from baseline using a 7-point scale, ranging from 1 (very much improved) to 7 (very much worse), with a score of 4 indicating no change.
The change from the patient's baseline condition is assessed by the Investigator at all post-baseline visits.

At baseline and Week 16
|
Change From Baseline to Week 16 in the Parkinson's Disease Questionnaire-39 Items (PDQ-39) Score
Time Frame: At baseline and Week 16
|
The PDQ-39 comprises 39 questions measuring eight dimensions of health: mobility, activities of daily living, emotional well-being, stigma, social support, cognition, communication and bodily pain.
Dimension scores are coded on a scale of 0 (perfect health as assessed by the measure) to 100 (worst health as assessed by the measure).
