E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this trial is to explore whether safinamide, administered orally at a dose of 100 mg daily for 12 weeks under double-blinded conditions as add-on therapy to a stable dopaminergic therapy, is superior to placebo in improving cognition in non-demented (ND) subjects with idiopathic PD and subjective complaints of cognitive dysfunctions. |
|
E.2.2 | Secondary objectives of the trial |
1. Explore whether safinamide, administered orally at a dose of 100 mg daily as add-on therapy to stable dopaminergic therapy further improves cognition during a 12-week open-label phase. 2. Explore the influence of safinamide on two cognitive phenotypes (i.e., fronto-striatal executive deficits and posterior cortically based deficits). 3. Gather data on the potential of safinamide to improve mood, sleep, and behavior (including apathy). 4. Further assess the safety and tolerability of safinamide in PD subjects. |

Cognitive impairment must be confirmed by a total score ≤ 26 on the Montreal Cognitive Assessment 5. Subjects must be able to speak, read, and write in the language in which the tests are written and must be able to perform all assessments in this language 6. Subjects treated with dopaminergic therapy at a stable dose for at least four weeks prior to Screening and for the duration of the study 7. Subjects must understand and sign the appropriate approved Informed Consent Form(s), one for the study (mandatory), one for the pharmacogenetic evaluation (optional) |
