E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The PK profile of Ropinirole PR allows a continuous dopaminergic stimulation at receptors D2/D3 that could be translated - in a clinical setting- in an improved efficacy in reducing the wearing off time versus the DA agonists immediate release. The rational of this study is to evaluate the effect of ropinirole 24h prolonged release (Ropinirole PR) on wearing OFF induced by dopamine agonist’s immediate release (Ropinirole IR, Pramipexole IR) |
Il ropinirolo a rilascio prolungato (RRP), registrato in Italia nel Giugno del 2008, grazie al nuovo sistema di rilascio controllato geomatrix consente di avere livelli di farmaco stabili sull’arco delle 24 ore assicurando una stimolazione più continua e fisiologica. In questo studio pilota, randomizzato in aperto con valutazione in cieco, si vuole verificare se l’introduzione del RRP al posto dei dopamino agonisti a breve emivita, consenta di migliorare il fenomeno del WEARING-OFF in pazienti parkinsoniani in monoterapia. |

E.2.2 | Secondary objectives of the trial |
Mean change from baseline in the PDQ39 Mean change from baseline in Parkinson’s Disease Sleep Scale. Proportion of subjects with a score of much improved or very much improved on the CGI-I scale Mean change from baseline in the UPDRS - Motor Score Mean change from baseline in the UPDRS - Activities of Daily Living Adverse events incidence rate |
Valutazione e modifica delle scale: UPDRS II e III, Scale del sonno PDSS, CGI del miglioramento, effetti collaterali |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
A subject will be eligible for inclusion in this study only if all of the following criteria apply: Diagnosis of idiopathic Parkinson’s disease (according to modified Hoehn & Yahr criteria Stages I-IV) Subjects ia a stable DA agonists dose regimen for at least 18 months Subjects provided written informed consent for the study. Subjects are willing and able to comply with study procedures, including diary card completion and follow-up clinic visits. |
Saranno studiati venti pazienti con Malattia di Parkinson idiopatica, in trattamento monoterapico con ropinirolo standard o pramipexolo, che presentano fluttuazioni motorie. Verranno studiati solo pazienti in grado di riempire un diario clinico ON/OFF e firmare il consenso informato. I pazienti saranno randomizzati per seguire o la terapia precedente o per cambiare su RRP. |

E.4 | Principal exclusion criteria |
1. Late stage advanced subjects demonstrating incapacitating dyskinesias 2. Presence, or history within the previous 3 months, of significant and/or uncontrolled psychiatric, haematological, renal, hepatic, endocrinological, neurological (other than Parkinson’s disease), or cardiovascular disease or active malignancy (other than basal cell cancer). 3. Any abnormality, at screening, that the investigator deems to be clinically relevant on history, physical examination and in diagnostic laboratory tests including ECG. 4. Recent history of severe dizziness or fainting due to postural hypotension on standing. 5. Clinical dementia that in the judgment of the investigator would preclude assessment of the subject. 6. Subjects with neurotic behaviour, crippling degenerative arthritis or limb amputations, which would preclude efficacy or safety assessments. 7. Subjects with prior or current major psychosis (e.g. schizophrenia or psychotic depression) e.g., scoring 3 or 4 on UPDRS item 2 (thought disorder) or item 3 (depression). 8. Recent history or current evidence of drug abuse or alcoholism. |
1. stato di malattia avanzato o con discinesie gravi 2. presenza nella storia clinica dei tre mesi precedenti di malattie significative o non ben controllate farmacologicamente, di natura pschiatrica, ematologica, renale, epatica, endocrinologica, neurologica (oltre il Parkinson), cardiovascolare o tumori in fase attiva. 3. ogni parametro clinico che risulti significativo allo screening al giudizio dello sperimentatore. 4. storia recente di ipotensione o svenimenti 5. demenza 6. disturbi del comportamento o amputazioni di arti che precludano la valutazione clinica 7. sogetti con storia di psicosi significative 8. storia recente di abuso di sostanze o alcool |
