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 been diagnosed with idiopathic PD at ≥ 30 years of age.
3. Patients must have predictable motor fluctuations of the wearing OFF type with
the presence of at least 2 hours 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 at the baseline visit.
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 the
initial screening visit there must be diary evidence of at least one transition of
OFF to ON or from ON to OFF and patients must show 75% concordance with
Investigator?s completion of the diary card.
5. Patients must rate between II-IV on the Hoehn &Yahr scale when in an OFF
state.
6. Patients must be taking optimised levodopa therapy (according to 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 (includes bedtime/night time
dose).
7. Patients who are treated with dopamine agonists, COMT inhibitors or MAOB
inhibitors and other anti-PD drugs must be on optimised and stable doses for at
least 4 weeks prior to initial screening visit and must remain stable throughout
the study. Only levodopa dosage can be adjusted downwards in the first 8
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 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
F.1.3.1 Number of subjects for this age range
1. Pregnant or lactating women.
2. Women of child bearing potential unless infertile (including surgically sterile)
or practicing effective contraception (e.g. abstinence, IUD or barrier method
plus hormonal method). These patients must have a negative serum β-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. Fertile men not willing to use reliable contraception and fertile men with
partners not willing to use reliable contraception.
4. Patients with a past or present history of drug or alcohol abuse as per DSM IV
criteria.
5. Patients with a past (within one year) or present history 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. Patients with a past (within one year) or present history of suicidal ideation or
suicide attempts.
7. Patients with unstable abnormalities of the hepatic, renal, cardiovascular,
respiratory, gastro-intestinal, haematological, endocrine or metabolic systems
which might complicate assessment of the tolerability of the study medication.
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 baseline
visit) with medication known to induce the enzyme cytochrome P450 3A4
(refer to section 8.7.2 for list of prohibited meds).
10. Current or prior treatment (within 4 weeks prior to the baseline visit) with
tolcapone, methyldopa, budipine, reserpine, seroquel or intermittent use of
either liquid forms of levodopa or subcutaneous apomorphine.
11. Patients with previous stereotactic surgery (eg pallidotomy) for Parkinson?s
disease or with planned stereotactic surgery during the study period.
12. Patients receiving or with planned (next 6months) deep brain stimulation.
13. Patients who have received an investigational product within 4 weeks prior to
the baseline visit or patients that have participated in a previous study with
E2007.
14. Patients with clinically significant cognitive impairment (MMSE <24 and /or fulfilling DSM IV criteria for dementia due to Parkinson?s disease).
15. Patients with conditions affecting the peripheral 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 evaluation of any such
symptoms caused by the study drug.
16. Patients with any condition that would make the patient, in the opinion of the
Investigator, unsuitable for the study.
