E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to evaluate the change from baseline to W78 in dyskinesia using the Dyskinesia Rating Scale during the “on” phase, comparing safinamide (50-100 mg/day) to placebo. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are to evaluate the changes from baseline to W78 in motor fluctuations, motor function, activities of daily living, quality of life, change in global clinical status, change in levodopa dose, and cognition.
Evaluate the changes from baseline to W78 in depression, disease staging, cognition and Health Resource Utilization. |

E.3 | Principal inclusion criteria |
To be eligible for inclusion into this trial, the subjects must fulfill all of the following criteria: 1. The subject completed 24 weeks of treatment in trial 27919. 2. The subject successfully completed all trial requirements in trial 27919. 3. If female, they must be either post menopausal for at least 2 years, surgically sterilized or have undergone hysterectomy or, if of child bearing potential they must be willing to avoid pregnancy by using an adequate method of contraception as defined in Section 6.4.9 of the protocol for four weeks prior to, during and four weeks after the last dose of study medication. For the purposes of this trial, women of childbearing potential are defined as: “All female subjects after puberty unless they are post-menopausal for at least two years, are surgically sterile or are sexually inactive”. 4. Subject is willing and able to participate in the trial and has provided written, informed consent. 5. Be able to maintain an accurate and complete diary (18-hour), with the help of a caregiver, recording “on” time, “on” time with minor dyskinesia, “on” time with troublesome dyskinesia, “off” time and time asleep.

The subject has shown clinically significant deterioration during participation in trial 27919. 4. Motor deterioration during trial 27919 that requires upward titration of existing anti-parkinsonian medication or the initiation of an additional anti-parkinsonian medication. 5. The investigator deems it is not in the subject’s best interest to participate to trial 27937. 6. Signs and symptoms suggestive of transmissible spongiform encephalopathy, or family members who suffer(ed) from such.
