Inclusion Criteria

1. Male or female patients with idiopathic PD fulfilling the (United Kingdom [UK])
Parkinson’s disease Society Brain Bank diagnostic criteria, with a good response to levodopa.
2. Patients must have been diagnosed with idiopathic PD at = 30 years of age. In
addition the onset of symptoms associated with Parkinson’s disease must have
occurred = 30 years of age.
3. Patients must have predictable motor 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 Screening
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 [DDI]) 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 Screening visit and must remain stable throughout the study. (revised per Amendment 02) 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.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes

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 ß-human chorionic gonadotrophin (ß-HCG) test at the initial screening visit (Visit 1) and a negative urine pregnancy 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 (4th edition; DSM IV) criteria.
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 pheochromocytoma.
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 Screening visit) with pergolide (only applies to patients entering after April 5, 2007), cabergoline (effective as of the date of the IRB/IEC approval of this amendment), tolcapone, methyldopa, budipine, reserpine, quetiapine or intermittent use of either liquid forms of levodopa or subcutaneous apomorphine. (revised per Amendment 02)
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 who have participated in a previous study with E2007.
(revised per Amendment 02)
17. Patients with clinically significant cognitive impairment (Mini-Mental State
Examination [MMSE] <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) th
