CEP-1347 10mg

CEP-1347 was administered at a dosage of 10mg twice daily (bid); capsule strengths were 5, 12.5, and 25 mg. Each patient took 2 capsules at each dosing time, approximately 12 hours apart, within 30 minutes after the morning and evening meals) for a total of 4 capsules per day.Patients were randomly assigned to CEP-1347 or placebo treatment in a 1:1:1:1 ratio. A blocked randomization scheme was used to ensure approximately equal numbers of patients in each of the 4 treatment groups at each center.

Group Type EXPERIMENTAL

CEP-1347 25mg

CEP-1347 was administered at a dosage of 25mg twice daily (bid); capsule strengths were 5, 12.5, and 25 mg. Each patient took 2 capsules at each dosing time, approximately 12 hours apart, within 30 minutes after the morning and evening meals) for a total of 4 capsules per day.Patients were randomly assigned to CEP-1347 or placebo treatment in a 1:1:1:1 ratio.

Inclusion Criteria

Patients will be included in the study if all of the following criteria are met:

* Willing and able to give informed consent
* Age 30 years or older at time of diagnosis of Parkinson's disease
* Have idiopathic Parkinson's disease with at least 2 cardinal signs of disease: resting tremor, bradykinesia, or rigidity

Women must be given a pregnancy test unless they are at least 2 years postmenopausal or surgically sterile.

Exclusion Criteria

Patients will be excluded from participating in this study if 1 or more of the following criteria are met:

* Have any other known medical or psychiatric condition that may compromise participation in the study
* Have a history of prior malignancy (excluding basal or squamous cell cancer of the skin) within the previous 5 years
* Have an unresolved abnormal cancer screening test result before randomization
* Have greater than trace amounts of glycosuria at screening, except for known diabetic patients
* Have estimated creatinine clearance less than 50 mL/min
* Have liver function tests (LFT) greater than 3 times the upper limit of normal (ULN)

* Have any history of malignant melanoma
* Have history of seizures (except febrile) or posttraumatic epilepsy
* Have Mini-Mental State Exam (MMSE) score ≤ 26
* Have taken another investigational drug within 60 days before the baseline visit
* Have received prior treatment with CEP-1347
* Have received treatment with agents with potentially confounding anti-Parkinson's disease effects, with specified substrates for CYP3A4/5, or with inhibitors of CYP3A4/5
* Received treatment within 6 months before the baseline visit with agents that may induce Parkinson's disease
* Are expected, within the next 3 months, to reach a level of disability sufficient to require dopaminergic therapy
