E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the efficacy of one dose strenght 4 mg of E2007 with that of placebo on motor function in patients with Parkinson s disease PD who are on optimised and stabilised therapy and experience end-of-dose wearing off motor fluctuations |
|
E.2.2 | Secondary objectives of the trial |
To demonstrate that the efficacy of entacapone on motor function in patients with PD who are on optimised and stabilised therapy and experience end-of-dose wearing off motor fluctuations, is consistent with what has been reported in other clinical trials. To compare the safety and tolerability of E2007 to that of placebo. Other To assess the efficacy of E2007 on levodopa iduced dyskinesias as measured by the Unified Parkinson s Disease Rating Scale UPDRS part IV dyskinesia items and the patient diary. To compare the effects of E2007 to that of placebo on levodopa use. |

E.3 | Principal inclusion criteria |
1. Male or female patients with idiopathic PD fulfilling the UK Parkinson s disease Society Brain Bank diagnostic criteria, with a good response to levodopa. 2. Patients must have diagnosed with idipathic PD at 8805;30 years of age. In addition the onset of symptoms associated with Parkinson s disease must have occurred 8805;30 years of age. 3. Patients must have predictable moto fluctuations of the wearing OFF type with the presence of at least 2 hrs of OFF time during the waking day excluding the morning OFF time as evidenced by diary cards completed at screening and confirmed by diary data collected in the 3-day diaries completed before randomisation. 4. Before patients are randomised, they must be able to show that they are able to accurately complete the diary cards. During the diary-training period at Screeening Visit 1, there must be diary evidence of at least one transition of OFF to ON or from ON to OFF. 5. Patients must rate between II-IV on the Hoehn Yahr scale when in an OFF state. 6. Patients must be taking optimised levodopa plus dopamine decarboxylase inhibitors therapy according to the Investigator s opinion at least 3 times during the waking day not including bedtime/night time dose up to a maximum of 8 doses daily including bedtime/night time dose . 7.Patients who are treated with DA or MAOB inhibitors or other anti-PD drugs must be on optimised and stable doses for at least 4 weeks prior to the baseline visit and must remain stable throughout the study. Only levodopa dosage can be adjusted downwards in the first 6 weeks of the double-blind treatment phase. 8. In the Investigator s opinion, patients must be able to distinguish their own motor states and the absence or presence of troublesome or non-troublesome dyskinesias. 9. In the Investigator s opinion, patients are able to complete the study including the completion of the home diary cards and are capable of giving full written informed consent. |

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. abstinence, intrauterine device or barrier method plus hormonal method . These patients must have a negative serum 946;-human chorionic gonadotrophin 946;-HCG test at the initial screening visit Visit 1 and a negative urine pregnangy test at the baseline visit Visit 3 . These patients must also be willing to remain on their current 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 or present history of drug or alcohol abuse as per Diagnostic and Statistical Manual of Mental Disorders 4ht edition; DSM IV cirteria. 4. Patients with a past within 1 year or present history of psychotic symptoms requiring anti-psychotic treatment. Patients may be taking anti-depressant medication; however, the dose must be stable for 4 weeks prior to the Screening visit. Use of anti-psychotic medication including clozapine and quetiapine is prohibited. 5. Patients with a past within 1 year or present history of major depression, suicidal ideation or suicide attempts. 6. Patients with unstable abnormalities of the hepatic, renal, cardiovascular, respiratory, gastro-intestinal, haematological, endocrine or metabolic systems that might complicate assessment of the tolerability of the study medication. 7. Patients who have a past or present history of liver impairment, neuroleptic malignant syndrome, non-traumatic rhabdomyolysis or pheochoromocytoma. 8. Patients with significantly elevated liver enzymes abnormal bilirubin or serum transaminase levels of more than 1.5 times the upper normal limit . 9. Patients with current or prior treatment within 4 weeks prior to the Screening visit with medication known to induce the enzyme CYP3A4 refer to section 9.8.2 for list of prohibited medications . 10. Current or prior treatment within 4 weeks prior to the Baseline visit with tolcapone, methyldopa, budipine, reserpine, quetiapine or intermittent use of either liquid forms of levodopa or subcutaneous apomorphine. 11. Current treatment with non selective MAOA/B or combination of selective MAOA and selective MAOB inhibitors. 12. Patients with a known hypersensitivity to the active substance or to any of the excipients of entacapone. 13. Patients with previous stereotactic surgery e.g. pallidotomy for PD or with planned stereotactic surgery during the study period. 14. Patients receiving or with planned next 6 months deep brain stimulation. 15. Patients who have received entacapone previously or are currently using entacapone. 16. Patients who have received an investigational product within 4 weeks prior to the screening visit or patients that have participated in a previous study with E2007. 17 Patients with clinically significant cognitive impairment Mini-Mental State Examination 24 or fulfilling DSM IV criteria for dementia due to PD . 18. Patients with conditions affecting the peripheral or central sensory system unless related to PD 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. 19. Patients with any condition that would make the patient, in the opinion of the Investigaotr, unsuitable for the study. |
