E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objectives of this trial are to evaluate the safety and efficacy of two doses of safinamide (50 and 100 mg p.o. q.a.m.), compared to placebo, as add-on therapy in subjects with early idiopathic Parkinsons Disease who are currently receiving a stable dose of a single dopamine agonist. Evaluate the changes from baseline to W24 in motor symptoms (UPDRS Section III). |
|
E.2.2 | Secondary objectives of the trial |
Evaluate the changes from baseline to W24 in activities of daily living, cognition, change in global clinical status and health related quality of life |

E.2.3 | Trial contains a sub-study | Information not present in EudraCT |
E.3 | Principal inclusion criteria |
1. Diagnosis of idiopathic Parkinsons disease of less than 5 years duration, with a Hoehn and Yahr stage of I-III. The diagnosis should be based on medical history and neurological examination. 2.

If female, be either post-menopausal for at least 2 years, surgically sterilised or have undergone hysterectomy or, if of child bearing potential, be willing to avoid pregnancy by using an adequate method of contraception as defined in Section 6.4.9 for four weeks prior to, during and four weeks after the last dose of trial 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. Receiving treatment with a single dopamine agonist at a stable dose for at least 4 weeks prior to the screening visit. 5. Willing and able to participate in the trial and have provided written, informed consent |
