E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the long-term safety and tolerability of E2007 as an adjunctive therapy in levodopa treated Parkinsonメs disease (PD) patients with motor fluctuations. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the long-term efficacy of E2007 on the motor fluctuations of Parkinsonメs Disease including the duration of OFF time during the waking day, and ON period dyskinesias |
|
E.2.3 | Trial contains a sub-study | Information not present in EudraCT |
E.3 | Principal inclusion criteria |
Male or female patients with idiopathic PD who have fulfilled the entry criteria to either E2007-E044-301 or E2007-A001-302 and have completed that study up to and including the final efficacy visit. Patients will not be eligible if they withdrew from the core study prior to the final efficacy visit for any reason including lack of efficacy. Patients with SAEs which are ongoing or possibly or probably related to the study drug, will not be eligible for this study. Patients with ongoing adverse events categorized as severe and thought to be related to E2007 should not be entered. Patients with mild or moderate adverse events thought to be related to E2007 can be entered to the study if the investigator considers it safe. |

E.4 | Principal exclusion criteria |
1. Pregnant or lactating women. 2. Women of child bearing potential unless infertile (including surgically sterile) or practicing effective contraception (e.g. adstinence, IUD or barrier method plus hormonal method). These patients must have a negative serum or urine β-HCG test at their firs study visit. These patients must also be willing to remain on theircurrent form of contraception for the duration of the study. Postmenopausal women may be recruited but must be amenorrhoeic for at least 1 year to be considered of non-child bearing potential as determined by the investigator. 3. Patients with a past (within the past 5 years) or present history of drug or alcohol abuse as per DSM IV criteria. 4. Patients with a past (within one year) or present history of suicidal ideation or suicide attempts. 5. Patients with a past (within one year) or present hisotry of psychotic symptoms requiring antipsychotic treatment. Patients may be taking anti-depressant medication, however the dose must be stable for 4 weeks prior to the baseline visit. Use of anti-psychotic medication including clozapine and quetiapine is prohibited even if the indication is for movement disorders. 6. Patient with unstable abnormalities of the hepatic, renal, cardiovascular, respiratory, gastro-intestinal, haematological, endocrine or metabolic systems wich migh complicate assessment of the tolerability of the study medication. 7. Patients with significantly elevated liver enzymes (abnormal bilirubin or serum transaminase levels of more than 1.5 times the upper normal limit). 8. Medication known to induce the enzyme cytochrome P450 3A4 is prohibited throught the study. 9. Current or prior treatment (within 4 weeks prior to entry visit) with tolcapone, methyldopa, budipine, reserpine, seroquel. 10. Patients with conditions affecting the perpheral or central sensory system unless related to Parkinson's disease (such as mild sensory or pain syndromes limited to OFF periods) that could interfere with the evalutation of any such symptoms caused by the study drug. 11. Patients receiving or with planned (next 12 months) deep brain stimulation. 12. Patients with any condition that would make the patient, in the opinion of the investigator, unsuitable for the study. |
