Drug and/or alcohol abuse within 12 months prior to the screening visit.~10. History of dementia or severe cognitive dysfunction.~11. Use of any investigational drug or device within 30 days prior to screening or 5 half-lives, whichever is the longest, or during the study.~12. Allergy/sensitivity or contraindications to the investigational medicinal products (IMPs) or their excipients, to anticonvulsants or to anti-Parkinson drugs.~13. Any clinically significant condition (including laboratory values) which, in the opinion of the Investigator, would not be compatible with study participation or represent a risk for patients while in the study.~14. Moderate or severe liver failure using the Child-Pugh classification score, or human immunodeficiency virus (HIV) infection.~15. Treatment with monoamine oxidase inhibitors (MAOIs), pethidine, opiates, opioids, fluoxetine, fluvoxamine in the 4 weeks prior to the screening visit. These drugs are not allowed throughout the study and up 2 weeks after the last dose of study drug.~16. Ophthalmologic history including any of the following conditions: albinism, uveitis, retinitis pigmentosa, retinal degeneration, active retinopathy, severe progressive diabetic retinopathy, inherited retinopathy or family history of hereditary retinal disease.

Study Arms:
- Safinamide (Type: EXPERIMENTAL): 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.
- Placebo (Type: PLACEBO_COMPARATOR): 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.
