| E.1.3 | Condition being studied is a rare disease  |  No  | 
| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
| The aim of this study is to investigate in patients with early Parkinsons disease the putative neuroprotective action of rasagiline as an add-on treatment to ongoing ropinirole therapy, by means of a delayed start design of the MAO-B inhibitor | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
| This study project is aimed to assess in patients with early PD the long-term tolerability and efficacy of the combined therapy of the DA-agonist ropinirole and rasagiline, resulting from the  possible neuroprotective action of the MAO-B inhibitor in conjunction with the symptomatic effect of the two drugs | 
 
 
 | 
| E.2.3 | Trial contains a sub-study  |  No  | 
| E.3 | Principal inclusion criteria  | 
�Duration of Parkinsons disease  not longer than 24 months, Hoehn & Yahr stage I- II,  patients age 40 to 75 �Patients  on current non ergot DAagonist  treatment for not longer than 6 months for ropinirole and not longer than 5 months for pramipexole, at minimum  daily dosage of 8 mg for the former and of 1.5 mg for the latter, maintained stable for at least 4 weeks, or patients previously untreated with DAergic drugs de novo patients �To have given informed written consent to participate in the study | 
 
 
 | 
| E.4 | Principal exclusion criteria | 
�Diagnosis of secondary Parkinsonism or atipical degenerative Parkinsonism �Pregnant or suckling female patients  �History of alcohol or other substance abuse during the last 12 months �Contra-indication to the use of the drugs investigated in the study �Patients previously exposed to rasagiline or other Daergic drugs, as l-dopa, selegiline, amantadine, apomorphine, ergot-derived DAergic agonists. Patients treated with anticholinergics will be accepted if these drugs will be discontinued at least 3 weeks before inclusion �Current or previous therapy with neuroleptics or other DA-antagonists �Current or previous diagnosis of psychosis or  current diagnosis of mood depression of  moderate to severe degree (score of Beck Depression Inventory scale >17) to require or to have required antidepressant medication �Patients with behaviour disturbances, such as medication-related altered impulse control,  repetitive behaviours and dopamine dysregulation syndrome  �Patient cognitively impaired (Mini Mental State score < 24) �Current or remitting neoplastic diseases and other diseases involving the central or peripheral nervous system  �Inclusion of the patient in other clinical study in which the use of the same or other drugs is scheduled | 
 
 
 | 
| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| Primary outcome measure  will be considered the degree of  motor impairment to require l-dopa  therapy, as an index of  disease progression. The degree of functional motor impairment to require l-dopa  will be evaluated by means of UPDRS part II (total score higher than 15), Schwab & England scale (threshold value 70% of residual function in daily living activities, as compared to the condition preceding disease onset) and patients quality of life self-assessment (PDQ39) (total score higher than 30). At least two out of three above threshold values/scores have to be reached. |
