Brief Summary:
The study is a placebo controlled study, with two parallel arms, in which participants will be randomly assigned in a 2:1 ratio to receive either active (200 mg safinamide) or placebo in a double blind manner. Study population is patients diagnosed, with possible or probable parkinsonian variant of Multiple System Atrophy who are on a stable treatment of levodopa

Condition or disease Intervention/treatment Phase
Multiple System Atrophy Drug: Safinamide Methanesulfonate Drug: Safinamide Methanesulfonate matching placebo Phase 2

Detailed Description:

The overall design is a parallel group, placebo controlled, double blind study. The target population are participants diagnosed with possible or probable parkinsonian variant of Multiple System Atrophy who are on stable doses of levodopa.

Trial participation will be up to a maximum duration of 14 weeks and will comprise a screening period (up to 2 weeks), a 2-week run in period during which subjects will receive 1 tablet (either 100 mg safinamide or matching placebo), followed by a 10-week period, during which study participants will take 2 tablets of study medication (200 mg safinamide or placebo) once daily, taken in the morning in addition to their morning levodopa dose. A telephone follow-up call will be performed 2 weeks after the end of treatment.

Primary Outcome Measures :
  1. TEAEs (Treatment Emergent Adverse Events) and SAEs (Serious Adverse Events) [ Time Frame: Throughout the study, from baseline (and at each interim visit) to telephone follow-up visit at 14 week. ]
    While evaluating safety and tolerability of safinamide, 200 mg od, compared with placebo, severity of TEAEs, their relationship to study drug, their seriousness and their consequences were assessed. TEAEs were defined as adverse events (AEs) that started after the first dose of study drug.


Secondary Outcome Measures :
  1. Change From Baseline to Week 12 in the Goniometric Measurement for Anterior Displacement [ Time Frame: From baseline to week 12 ]
    To evaluate the potential efficacy of safinamide 200 mg od, as add-on therapy, on quality of life (change in anterior displacement). The goniometric measurement consists in the posture evaluation of the patient, measuring through a goniometer the angle of the flexion of the trunk. Goniometric measurement of "anterior" displacement was determined using a wall goniometer and expressing the value in degrees in the range of 0 to 90.

  2. Change From Baseline to Week 12 in the Goniometric Measurement for Lateral Displacement [ Time Frame: From baseline to week 12 ]
    To evaluate the potential efficacy of safinamide 200 mg od, as add-on therapy, on quality of life (change in anterior displacement). The goniometric measurement consists in the posture evaluation of the patient, measuring through a goniometer the angle of the flexion of the trunk. Goniometric measurement of "lateral" displacement was determined using a wall goniometer and expressing the value in degrees in the range of 0 to 90.

  3. Change From Baseline to Week 12 in Unified Multiple System Atrophy Rating Scale (UMSARS), Part II (ITT Population) [ Time Frame: From baseline to week 12 ]

    UMSARS is a validated, disease-specific scale representing the diverse signs and symptoms in MSA. Higher scores on the UMSARS scales mean poorer health.

    UMSARS has the following domains:

    Part I - Activities of Daily Living score (12 questions ranged in 0-4 [total score 0-48]) that evaluates motor including autonomic activities Part II - Motor Examination score (14 questions, [total score 0-56]) Part III - Autonomic Examination Part IV - Global disability scale ((1=completely independent; 2=not completely independent; 3=more dependent; 4=very dependent; 5=total dependent and helpless).

    Only UMSARS Part II total score is reported, which was obtained as the sum of the 14 items in the scale. If any of the items were missing, then the total score was considered missing. Higher scores indicate worse functional situation.


  4. Change From Baseline to Week 12 in Unified Multiple System Atrophy Rating Scale (UMSARS), Part II (PP Population) [ Time Frame: From baseline to week 12 ]

    UMSARS is a validated, disease-specific scale representing the diverse signs and symptoms in MSA. Higher scores on the UMSARS scales mean poorer health.

    UMSARS has the following domains:

    Part I - Activities of Daily Living score (12 questions ranged in 0-4 [total score 0-48]) that evaluates motor including autonomic activities Part II - Motor Examination score (14 questions, [total score 0-56]) Part III - Autonomic Examination Part IV - Global disability scale ((1=completely independent; 2=not completely independent; 3=more dependent; 4=very dependent; 5=total dependent and helpless).

    Only UMSARS Part II total score is reported, which was obtained as the sum of the 14 items in the scale. If any of the items were missing, then the total score was considered missing. Higher scores indicate worse functional situation.


  5. Change From Baseline to Week 12 in Multiple System Atrophy Health-Related Quality of Life (MSA-QoL) Scale [ Time Frame: From baseline to week 12 ]
    The MSA-QoL is a self-reported questionnaire focusing on MSA-specific symptoms and has a scale ranging from 0 to 160, with 0= 'no problem' and 160= "extreme problem".

  6. Change From Baseline to Week 12 in Montreal Cognitive Assessment (MoCA) Scale [ Time Frame: From baseline to week 12 ]
    The Montreal Cognitive Assessment (MoCA) was designed as a tool for rapid screening for mild cognitive impairment. It evaluates different cognitive domains: attention and concentration, executive functions, memory, language, visuoconstructive skills, abstraction, calculation and orientation. The administration time of the MoCa is 10 minutes. The MoCA scale ranges from 0 to 30, with higher scores indicating better cognitive functioning.

  7. Change From Baseline to Week 12 in Unified Dystonia Rating Scale (UDRS) [ Time Frame: From baseline to week 12 ]

    UDRS consists of a Historical Section, divided into questionnaires about 1) on-dyskinesia and 2) off -dystonia, and an Objective Section, divided into 3) impairment and 4) disability scales. The Historical Section is scored from 0-60, and the Objective section is scored 0-44, where higher scores reflect greater difficulty or impairment.

    The Unified Dystonia Rating Scale (UDRS) assesses the motor severity and duration of dystonia in 14 body areas. The total score, obtained as the sum of the severity and duration factors, ranges from 0 to 112. Higher scores indicate worse dystonia.
