Patients who have completed one of the core trials (E2007-E044-301 or E2007-A001-302) and who meet inclusion/exclusion criteria will be enrolled and will enter the Titration Phase, lasting 4 weeks (weeks 0-3) followed by the Maintenance Phase, lasting 52 weeks (weeks 4-56). All patients will receive active study drug. During the Titration Phase, patients will receive E2007 2 mg once daily (o.d.) for 2 weeks followed by 4 mg o.d. for 2 weeks. During the Maintenance Phase, patients will receive 4 mg o.d. Patients not tolerating the study drug at 4 mg, will be allowed to down titrate to 2 mg. Patients not tolerating 2 mg will be withdrawn from the study.
Patients will have visits at 2, 4, 8, 20, 32, 44, and 56 weeks after study entry. In addition, a follow-up visit will occur 4 weeks after study treatment has ended (week 60).
A home diary will be completed in which patients rate themselves as either:
2. ON without dyskinesia
3. ON with non-troublesome dyskinesias
4. ON with troublesome dyskinesias
These entries will be completed every half hour during the waking day and will be completed for 3 consecutive days following the visits at weeks 4, 8, 20, 32 and 44, and three days prior to the visits at weeks 56 and 60. At entry into the study (week 0) and at weeks 8, 20, 32, 44 and 56, the Unified Parkinson's Disease Rating Scale (UPDRS), Clinician's Global Impression of Change (CGIC) and Clinical Global Impression of Tolerance (CGIT) will be performed.

Visual hallucinations (VHs) are common in Parkinson's disease (PD), with prevalence ranging from 27-50% in cross-sectional cohorts of patients with well-established disease. However, minor hallucinati...
Neuroimaging in Parkinson's disease is an evolving field, providing in-vivo insights into the structural and biochemical changes of the condition, although its diagnosis remains clinical. Here, we aim...
Common forms of Parkinson's disease have long been described as idiopathic, with no single penetrant genetic factor capable of influencing disease aetiology. Recent genetic studies indicate a clear as...
Proteins associated with sporadic or familial cases of PARKINSON DISEASE.
A condition caused by the neurotoxin MPTP which causes selective destruction of nigrostriatal dopaminergic neurons. Clinical features include irreversible parkinsonian signs including rigidity and bradykinesia (PARKINSON DISEASE, SECONDARY). MPTP toxicity is also used as an animal model for the study of PARKINSON DISEASE. (Adams et al., Principles of Neurology, 6th ed, p1072; Neurology 1986 Feb;36(2):250-8)
A group of disorders which feature impaired motor control characterized by bradykinesia, MUSCLE RIGIDITY; TREMOR; and postural instability. Parkinsonian diseases are generally divided into primary parkinsonism (see PARKINSON DISEASE), secondary parkinsonism (see PARKINSON DISEASE, SECONDARY) and inherited forms. These conditions are associated with dysfunction of dopaminergic or closely related motor integration neuronal pathways in the BASAL GANGLIA.
Parkinsonism following encephalitis, historically seen as a sequella of encephalitis lethargica (Von Economo Encephalitis). The early age of onset, the rapid progression of symptoms followed by stabilization, and the presence of a variety of other neurological disorders (e.g., sociopathic behavior; TICS; MUSCLE SPASMS; oculogyric crises; hyperphagia; and bizarre movements) distinguish this condition from primary PARKINSON DISEASE. Pathologic features include neuronal loss and gliosis concentrated in the MESENCEPHALON; SUBTHALAMUS; and HYPOTHALAMUS. (From Adams et al., Principles of Neurology, 6th ed, p754)
Conditions which feature clinical manifestations resembling primary Parkinson disease that are caused by a known or suspected condition. Examples include parkinsonism caused by vascular injury, drugs, trauma, toxin exposure, neoplasms, infections and degenerative or hereditary conditions. Clinical features may include bradykinesia, rigidity, parkinsonian gait, and masked facies. In general, tremor is less prominent in secondary parkinsonism than in the primary form.
