PHASE2
Brief Summary
This is a randomized, double-blind, two treatment, two group, parallel group study. Subjects will be randomized to one of two treatment groups (E2007 or Placebo) in a 3 to 1 ratio and receive treatmen...
Eligibility Criteria
Inclusion
- Subjects of any race greater than or equal to 30 years of age
- Have a diagnosis of idiopathic Parkinson's disease. Subjects should fulfill the UK Parkinson's Disease Society Brain Bank Clinical Diagnostic criteria (Queen Square criteria) and have a rating of 2 - 4 on the Hoehn and Yahr scale when in an 'off' state.
- Receiving an optimized regimen of anti-Parkinsonian treatments that has been stable for at least four weeks before baseline. The regimen is not considered to be stable if "as required" or "on demand" dosing is routinely used or there is regular use of apomorphine or liquid forms of levodopa.
- Taking levodopa or levodopa-containing medications (e.g. co-beneldopa, cocareldopa) at least three times daily with a good response to each levodopa dose as evidenced from patient diaries or medical notes.
- Consistently experience end-of-dose "wearing-off" motor fluctuations. Subjects should:
- score greater than or equal to 1 on Question 39 (What proportion of the waking day is the patient "off" on average?) of the full UPDRS at screening.
- have at least 2.5 hours of "off" time on average per day recorded in the patient diary at baseline.
- Willing and able to provide written informed consent and adhere to the protocol requirements, including completion of a patient diary.
Exclusion
- Receiving treatment with medication known to induce CYP3A4 activity
- Previous stereotactic surgery (e.g. pallidotomy, subthalamic nucleus deep brain stimulation) for Parkinson's disease
- Received an investigational product within four weeks prior to screening or having participated in a previous study with E2007.
- Clinically significant cognitive impairment \[mini-mental state examination (MMSE) less than 24 or fulfilling DSM IV criteria for dementia due to Parkinson's disease\].
- Active hepatic disease, significantly reduced hepatic function or significantly elevated liver enzymes (abnormal bilirubin or serum transaminase levels of more than 1.5 times the upper limit of the normal range).
- Clinically significant ECG abnormality, including prolonged QTc (defined as QTc greater than or equal to 450 msec for males and greater than or equal to 470 msec for females using Fridericia's correction).
- Clinically significant, cardiovascular, metabolic, respiratory, renal, endocrinological, gastrointestinal diseases, psychiatric disorders, and bacterial or viral infections within the previous 30 days.
- History of drug or alcohol abuse.
- Women who are pregnant or lactating.
- Any condition that could, in the opinion of the investigator, place the subject at increased risk or is likely to prevent completion of the study
