NCT00087542

Brief Summary

The primary objective is to demonstrate that the investigational new drug, ACP-103, is well tolerated by, and will not worsen parkinsonism in, patients with Parkinson's disease and psychosis. The secondary objectives are to determine whether ACP-103 will ameliorate psychosis in patients with Parkinson's disease and whether ACP-103 is safe in Parkinson's disease patients taking multiple anti-parkinsonian medications.

Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Male and female patients of any ethnic group and of any age are eligible for participation in this study, providing they meet all the following criteria:
  • Subjects with a clinical diagnosis of idiopathic Parkinson's disease, defined as the presence of at least three of the cardinal features of the disease including: rest tremor, rigidity, bradykinesia and/or akinesia, postural balance abnormalities, in the absence of alternative explanations or atypical features.
  • Psychosis, defined by the presence of visual and/or auditory hallucinations, with or without delusions, of at least four weeks duration.
  • Psychosis, assessed by items A and B of the NPI, and defined as Hallucinations (Frequency x Severity) and Delusions (Frequency x Severity) = a total score of 4 or greater.
  • Stable anti-Parkinsonian medication(s) use for at least one week prior to study entry.
  • A reliable caretaker who will accompany the subject to each visit, and who can reliably report on the subject's daily level of function.

You may not qualify if:

  • Patients who meet any of the following conditions are excluded from the clinical study:
  • Inability of subject or caretaker to provide informed consent.
  • Pregnant or breastfeeding. Female subjects of child-bearing potential must have a negative urine pregnancy test at screening.
  • Female subjects must be of non-childbearing potential or must comply with double-barrier protection methods against conception during the study and for at least one month prior to randomization and one month following completion of the study.
  • Presence of any systemic factor contributing to the psychosis such as urinary infection, liver disease, renal failure, anemia, infection, etc. as defined by a comprehensive medical evaluation.
  • History of a significant pre-morbid psychiatric condition before the diagnosis of Parkinson's disease, including major depression, mania, or psychotic depression.
  • Dementia precluding accurate assessment on psychiatric assessment battery and defined as a score on the MMSE \< 21.
  • Use of depot neuroleptic within the past year.
  • Prior exposure to non-depot neuroleptics within the past 90 days, except for quetiapine or clozapine. Quetiapine and clozapine-treated patients may be enrolled if these agents were discontinued due to drug intolerability. Such patients must not have taken these drugs within the past two weeks.
  • Use of the following drugs within the past two weeks: benztropine, biperiden, trihexylphenidyl, amitriptyline, clomipramine, desipramine, nortriptyline, imipramine, doxepin, fluvoxamine, mirtazepine, nefazodone and trazodone.
  • Change of anti-depressant, anxiolytic, anticholinergic (specifically oxybutynin, tolterodine), or cognitive enhancer (specifically rivastigmine, tacrine, donepezil, galantamine) dose within the past 30 days and during the 28-day duration of the trial.
  • Use of any investigational product within the past 30 days.
  • Inability to tolerate a stable level of anti-parkinsonian medications for one week.
  • Uncontrolled angina or history of a myocardial infarction within the past three months.
  • Concurrent illness that would make use of ACP-103 potentially hazardous.
