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
  • Modified Hoehn and Yahr stage less than or equal to 2.5
  • Must have had screening procedures for cancer appropriate for the patient's age and gender, within the last 12 months; or be willing to obtain such screening before randomization
  • Women: are not breastfeeding
  • Women: nonchildbearing potential (ie, postmenopausal or surgically sterile) or must use a medically accepted contraceptive regimen for at least 60 days before the baseline visit, and agree to continue such use throughout the duration of the study and for 30 days after the final dose of study drug. 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 atypical Parkinsonism due to drugs, metabolic disorders, encephalitis, or other neurodegenerative diseases
  • Have confirmed diagnosis of Parkinson's disease for more than 5 years
  • Have a tremor score of 3 or more in any body part
  • 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 other clinically significant ECG or laboratory finding
  • 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
  • Have BECK depression score ≥ 15
  • Have known or suspected sensitivity to the investigational study drugs, including B-CIT

CEP-1347 10mgCEP-1347 10mgCEP-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.

Primary Outcome Measures
NameTimeMethod
Number of participants with disability using United Parkinson's Disease Rating Scale (UPDRS)48 months

Number of participants with disability sufficient to require dopaminergic therapy was assessed according to the United Parkinson's Disease Rating Scale (UPDRS) Parts I and II are historical data and are designed to rate mentation, behavior and mood; Part III is done as a motor examination at the time of a visit. The UPDRS measures patient status on a scale 0, which is normal or none, to 4, which is severe or the worst scenario.

Secondary Outcome Measures
NameTimeMethod
Change from Baseline to 22 months in ([123I]β-CIT) Uptake ParticipantsChange from Baseline to 22 months

The effect of CEP-1347 on dopaminergic transporter density using 2β-carboxymethoxy-3β-(4-iodophenyl) tropane (\[123I\]β-CIT) single-photon emission computed tomography (SPECT) imaging

Safety and Tolerability as assessed by the number of participants experiencing adverse events48 months

Safety was assessed by adverse events (including deaths, serious adverse events, and withdrawals due to adverse events.)
